V. WOLF MANAGEMENT
STRATEGIES
A. Wolf Management Zones
Zone management is frequently recommended as part of wolf recovery plans
and management plans (Mech 1995). The Federal Recovery Plan for the
Eastern Timber Wolf provides 5 different zones for managing wolves in
Minnesota (U.S. Fish and Wildlife Service 1992). Fritts (1990, 1993)
suggested 3 levels of zone management for wolf management in the
Yellowstone Ecosystem. Fritts (1990) indicated that normally only 3
zone levels would be needed for wolf management to avoid unnecessary
confusion. On the other hand, the Alaska Board of Game adopted a
strategy for wolf management in 1991 that incorporated 7 zones, ranging
from Zone 1 (Full Protection) to Zone 7 (High Use/Intensive Management)
(Anonymous 1992).
The purpose of zone management is to vary management depending on
potential wolf habitat and the possibilities of conflicts between wolves
and humans. Fritts (1993) listed 3 assumptions inherent in zone
management for wolves:
Generally the fewer the zones, the more simplified the management and
greater the understanding by the public and agency personnel (Fritts
1990). A disadvantage to fewer zones is that less fine tuning of
management is possible.
The WDNR will utilize 3 zones to manage wolves in the state (Figure 7).
Such a system provides maximum protection in most portions of suitable
habitat, yet allows a flexible system for controlling wolves in less
suitable areas where higher levels of conflict are likely to occur. The
characteristics of the 3 zones under this management system are listed
below.
Figure 7. Wisconsin Wolf Management Zones.{Click image for larger view} |
Zone 1a - Public (Wolf Conservation Area): Zone 1a includes 7600 square
miles of public land and industrial forests in the Northern Forest and
Central Forest Deer Management units in Wisconsin. Zone 1a contains 71%
of the state's favorable wolf habitat. These areas could support an
estimated 210-350 wolves (Appendix C). Wolves on public lands and
industrial forests will be totally protected, with few exceptions.
Only wolves with contagious diseases, such as rabies and animals
suspected of being captive-raised or wolf-dog hybrids could be
euthanized. Habitat consists mainly of forest and contains little farm
land and no urban areas. Therefore potential conflicts with domestic
animals would be limited to pets. Reimbursement for losses, and perhaps
payments for abatement practices would be provided. Wolf habitat
maintenance would be encouraged on suitable portions of public lands by
access management, protection of den and rendezvous sites, and
management for younger forests to support prey populations. No major
change in management would be required in this zone as the wolf
population is delisted. The wolf population would be allowed to
fluctuate with the deer population. Deer populations would probably
fluctuate with winter severity and hunter harvest.
Zone 1b - Private (Wolf Conservation Area): This represents privately
owned lands where wolves would be controlled on a case-by-case basis.
Private lands in the northern forest and central forest deer management
units cover about 15,400 mi2. Most private lands would not be highly
suitable habitat for wolf packs, but it does contain some portions of
suitable habitat and could perhaps support 80-150 wolves. About 60-90%
of these private lands would be forest with scattered farmland. Because
of the high interspersion of wildland and developed areas, depredation
on pets and livestock could occur on private lands. Flexible management
would be necessary to control problem wolves. Wolves that have become
habitual depredators on livestock or pets on private land would be
euthanized and control activities would be conducted up to 0.5 mile from
depredating sites. Wolf packs that do not cause depredation would be
protected and habitat protection may be done on a case-by-case basis.
Under state delisting control in areas of chronic wolf problems may be
done by proactive trapping by government agents to reduce or eliminate
wolves from these areas.
Zone 2 (Wolf Buffer Area): This zone represents areas having very
limited habitat for packs to colonize, but probably contains patches of
suitable dispersal habitat that connects the north and central
management zones. The zone would cover about 18,000 mi2 including the
mixed forest/farming areas of central Wisconsin and the rugged Coulee
country of western Wisconsin. Most of the area has less than a 10%
chance of being occupied by wolf packs, but some of the rugged bluff
country or bottom land areas along the Mississippi River have greater
than 25% chance of being occupied by wolf packs. Generally less than 20
wolves are likely to occur in this zone. About 20-60% of the landscape
is in wildland areas. Because of the importance of maintaining genetic
diversity in the central forest wolf population, some level of
protection should be provided for dispersing wolves that could move into
this area. Unless these wolves cause problems, they should not be
controlled. Wolves that do become depredators on livestock or pets
should be vigorously controlled. Trapping by government agents can be
conducted up to 5 miles from depredating sites. Wolf packs that
establish may be allowed to persist, but if depredation occurs the whole
pack may be removed. Under state delisting, control of depredating or
nuisance wolves could also be done by landowners with WDNR permits. If
the wolf population builds up in an area and causes chronic problems,
pro-active trapping could be considered once delisting has occurred.
Zone 3 (Low Wolf Tolerance Area): This zone represents areas that have
almost no opportunity for colonization by wolf packs. Wolves entering
this zone have a high probability of conflicting with people. This zone
would include southern and eastern counties that have less than 20%
wildlands and would include all the urban areas across the state. The
zone would cover about 16,000 mi2.
Few wolves are likely to occur in this area. Although non-depredating
wolves that avoid areas of human or livestock concentration can receive
some level of protection, any wolf or wolf-like animal that lacks fear
of people and readily approaches pets, livestock or people should be
captured or controlled. Many of the wolf-like animals that would be
controlled under such circumstances would probably be free roaming
wolf-dog hybrids. Along with federal and state trappers, local law
enforcement and animal control officers should be allowed to control
nuisance wolf-like animals in this zone. Following state delisting,
landowners could be granted permission to control wolves or wolf-like
animals on their land.
Zone management alternatives considered: The wolf management team
considered alternatives involving: no zones, or two zones. The "no
zone" alternative was rejected because it provided no special protection
to wolves in areas of suitable habitat. All nuisance wolves would need
to be controlled on case-by-case basis.
The two zone alternatives did not seem to provide as high levels of wolf
protection in areas of suitable habitat, while allowing flexible
control in areas of conflict with nuisance wolves. The two zone
alternatives did not tie as closely into habitat considerations as
would a more complex system.
B. Population Monitoring
and Management
1. Population Monitoring
Accurate counts are necessary to determine if wolves are attaining
management goals. Radio tracking of collared individuals is the most
precise way to monitor wolf populations (Mech 1974). By observing
collared wolves with other pack members, complete counts can be made of
wolf packs in winter (Mech 1974). One or two radioed animals per pack
enables biologists to monitor whole packs. However, the presence of a
collared wolf is not always a guarantee that the whole pack will be
monitored. Sometimes collared wolves disperse prior to winter, or a
pack may occur in dense conifer cover where few observations are
possible. Snow tracking can be used to estimate pack size (Thiel and
Welch 1982, Wydeven et al. 1996). Counting wolves by snow tracking is
less precise than observing wolves from the air, but is useful for
assessing wolf numbers, especially if done in conjunction with radio
telemetry. Usually the tracks of a wolf pack need to be observed
several times over a winter to get an accurate count.
Howling surveys are useful for determining summer home sites for wolves
and pup production (Harrington and Mech 1982). These surveys are done
mainly from July to October. Although howling surveys rarely allow
opportunity for accurate counts of wolves, the technique does allow
assessment of relative numbers and helps to separate packs.
Since 1979, the Wisconsin DNR has surveyed the state wolf population
using the techniques described above. Wolf live-trapping has been
performed during each spring and summer (approximately May 1 to
September 15), and 3-17 wolves were caught and radio-collared each year.
Wolves were located by airplane 1-2 times per week and remained on the
air from 1 week to 4 or more years. Normally about 15-20% of the
population was captured each year and 30-40% of the population had
active transmitting collars during the year. During the winter about
50-60% of packs had at least one collared wolf. Usually 2 crews, each
consisting of 2-3 people, conducted live trapping each year.
It requires 10-12 days to trap each wolf. Radio collars placed on wolves
cost about $350 and it normally costs about $300 to locate all the
collared wolves using aerial surveys. It costs about $1,000-1,500 to
capture each wolf. Live-trapping and radio-tracking is the most precise
system for monitoring wolves, but is expensive.
Snow tracking has been used to supplement telemetry data on wolves.
Most winters, 2,500 - 3,000 miles of survey were conducted in suitable
habitat. These surveys normally proceed at about 4-5 miles per hour
thus representing 500-750 hours of track surveys.
During summers howling surveys are conducted in pack territories across
the state to determine pup productivity. These surveys take about 100
hours to complete.
As the wolf population continues to increase the intensity of monitoring
will decline. Federal funds for monitoring will be eliminated 5 years
after federal delisting. The WDNR will use less costly methods for
monitoring wolves in the future, and seek other sources for funding wolf
monitoring.
Existing and potential surveys that could help assess wolf abundance
include:
A volunteer carnivore track survey was initiated by the WDNR in fall
1995 (Wydeven et al. 1996). Surveyors were asked to conduct 3 or more
surveys of 20 - 30 miles each on snow covered roads in each of the 123
survey blocks (200 square miles each). In 1996, 32 of 46 (67%) surveys
were returned for assigned survey blocks, and in 1997, 37 of 51 (75%)
blocks were surveyed. Surveyors in 1997 conducted 3,317 miles of
survey, averaging 90 miles and 4.7 surveys per block. Volunteer
surveyors were very close to WDNR estimates of wolf numbers in 1996, but
much less in 1997, probably due to poor tracking conditions. Once the
volunteer tracking program has been adequately tested and refined, it
may also be used as a monitoring tool, and be turned over to a volunteer
organization such as the Timber Wolf Alliance (TWA).
General recommendations for wolf population monitoring under threatened
status and as a delisted population are described below.
Threatened Status Population Monitoring
Live-trapping of wolves and radio-tracking will continue. As the wolf
population increases from 100 to 300 or more, the percentage of wolves
captured and radio-collared each year will decline to probably less than
10%, with less than 40% of the packs having radio-collared wolves.
Emphasis would be on collaring packs in new areas or in research
projects where special funding is available. Other packs would be
monitored mostly by snow tracking and summer howling surveys. Greater
reliance would be on tracking and howling surveys conducted by
volunteers. Other WDNR surveys would also be used more extensively for
comparing wolf abundance with track and telemetry surveys.
Delisted Status Population Monitoring
Once the wolf population is delisted, most intense live-trapping and
radio-tracking surveys would decline, except on specific research
projects where funding is available. Two steps of population monitoring
would be followed after delisting occurs:
2. Population Management
Only wolves causing depredations on pets or livestock would be
euthanized while wolves are classified as threatened and such control
would only occur in Zones 1b, 2 and 3. All depredation control activity
would be conducted by WDNR or APHIS-WS. Under special circumstances,
authorization to control nuisance wolf-like animals can be given to
local law enforcement or animal control officers in urban areas.
Landowner control would not be considered while wolves are listed as
threatened.
Once delisted, the gray wolf would be classified as a "protected nongame
species" similar to the badger . Most control activity would continue to
be done by WDNR or APHIS-WS personnel. Within Zone 3 and urban areas,
local law enforcement officers and animal control officers could be
authorized by WDNR permit to control wolf-like nuisance animals that are
free-roaming in urban areas. Control in these type of situations should
be flexible and be based on animal behavior. Most wolf-like animals
that would be controlled in these situations would probably be wolf-dog
hybrids or captive raised wolves.
Under delisted status landowners in Zones 2 and 3 can be issued permits
to kill nuisance wolves on their land. Landowners would be allowed to
kill a limited number of wolves, and all wolf carcasses would be turned
over to the WDNR.
Once the number of wolves reaches a level at which social tolerance
demands a limit to the population the Department of Natural Resources
will request a change in the status of the wolf to an game animal which
will allow use of a managed public take to maintain the population at or
near established goals. This Administrative Code revision removing the
wolf from nongame status to furbearer/game animal will require public
hearing and comment. Such a change is consistent with the management of
other recovered populations. It would not mandate an immediate open
season. Take methods and rules as well as the number of wolves to be
taken would first have to be defined.
By definition population management necessitates the identification of a
desirable population of a species. Preliminary analyses show a
population of 300 Wisconsin wolves is necessary to establish and
maintain a sustainable population. GIS habitat and prey-based modeling
shows that the probable carrying capacity in the state would be about
500 wolves. We do not know the level at which social conflict may
require a limit to wolf numbers. That number must yet be established.
Currently the Wolf Advisory Committee recommends managing wolves at a
range of 300 to 500 until more information on social tolerance is
obtained. The DNR will review wolf population goals every 5 years at a
minimum to determine if changes in goals are necessary. Any change in
population goals would need thorough public review.
Clearly, no take of wolves would be allowed until wolf numbers exceed
the 300 level considered necessary to maintain a self-sustaining state
population.
Public take will be considered if needed to maintain the population at
or near carrying capacity. Wisconsin Department of Natural Resources
supports the hunting or trapping of species as a population management
tool. Public harvest must depend, however, on other mortality and
population goals.
C. Wolf Health Monitoring
Health monitoring is necessary to assess impact of diseases and
parasites on the wolf population. Health monitoring includes collection
and analysis of biological samples from live-captured wolves, analysis
of wolf scats, and necropsies. While federally listed as endangered/
threatened, biological samples of live captured wolves and analysis of
scats will be conducted by WDNR, and wolf necropsies will be conducted
by the National Wildlife Health Lab in Madison. When federal delisting
occurs, all health monitoring will be the responsibility of WDNR.
Intensive health monitoring will continue while wolves are listed as a
state endangered or threatened species. Live-captured wolves will be
tested for diseases, physiological condition and parasites. Ideally
about 10% of a population of 100 wolves should be examined, but as the
population continues to increase, the percentage of the population
live-captured will decline. In recent years 12 to 17 wolves were
captured annually. Wolf scats will be collected to monitor canine
viruses and parasite levels. Dead wolves will be necropsied to
determine cause of death, physical condition and disease status. .
Following state delisting, WDNR live-trapping will decline and
eventually be discontinued. Periodic scat analyses will be performed by
WDNR to test for diseases and parasite loads in wolves. WDNR will
continue to necropsy dead wolves as necessary to monitor health trends.
Special research studies may occasionally be conducted on wolves and
these should include health monitoring. Wolf health monitoring should
be part of the capture protocol of all live-capture studies of any wild
wolves in Wisconsin, and should be carefully coordinated with WDNR
wildlife health specialists.
D. Habitat Management
1. Potential and Favorable Wolf Habitat: Based on computer models
Wisconsin contains large tracts of potential wolf habitat (Mladenoff et
al.1995, 1997 Appendix C). The variables used to determine what makes
up potential habitat include human population density, prey (deer)
density, road density, vegetation cover, spatial landscape pattern, and
land ownership. Of these, road density and complexity of spatial pattern
are most important. Wolves have selected areas that are most remote
from human influence, and with the least amount of landscape pattern
(e.g. least amount of agricultural land, lakes, and other separate land
cover patches). Based on these findings, there is currently 5,812 mi2
(15,052 km2) of favorable wolf habitat in Wisconsin (Figure 6).
Favorable habitat is defined as areas that has a greater than 50%
probability of being occupied by wolf packs. Most of this favorable wolf
habitat is located on public land, especially county forests, followed
by national forests, and private industrial forests (Mladenoff et al.
1995 Appendix C). Wolves have naturally expanded into Wisconsin and
have better defined what favorable habitat is to them by currently
occupying 2,200 mi2 (5,700 km2), most of which is also within the areas
identified as favorable through computer models (Figure 6).
Primary Wolf Habitat by Land Ownership {Click image for larger view}
|
The Wolf Advisory Committee recommends cooperative habitat management
efforts with land agencies and industrial forest and private land
owners, especially in the 5812 mi2 of the most favorable habitat
(Mladenoff 1995, Appendix C). Habitat management should include efforts
at access management, corridor protection, vegetation management, and
den site protection. Such habitat management should continue for wolf
populations listed as threatened or delisted.
2. Access Management: Wolf populations are affected by human caused
mortality (see Appendix F). Motorized access, and the level of human use
on such access, has been shown to be a key factor in establishing and
maintaining wolf populations (Thiel, 1985; Mech et al. 1988). These
studies suggest that wolves exist primarily in areas with less than, or
up to, one linear mile of open improved road per square mile (0.6
km/km2). Mladenoff et al. (1995) showed that road densities within pack
territories were lower, averaging 0.37 mi/mi2 (0.23 km/km2). The
expanding wolf population in the Lake States, however, has shown
increased tolerance for slightly higher road densities in recent years
(WDNR unpubl. data; per comm. Bill Berg, MN DNR).
Access management is important for many economic, social, and biological
reasons. Managing the amount, type and level of public motorized access
is recommended for Zone 1 areas to minimize encounters between humans
and wolves that may result in accidental or intentional wolf deaths.
Access management can include avoidance of new road construction, using
temporary or winter-only roads, closure of existing roads not needed for
management or public access, gating or berming logging roads, and road
obliteration. Emphasis in access management should be on maintaining
existing road densities in areas of suitable habitat (Zone 1). Access
management may help reduce maintenance costs, provide remote
recreational experiences, and may benefit certain wildlife including
bear, marten, lynx, bobcat, moose, goshawk, and spruce grouse. In
deciding upon an access management program, variables such as
administrative controls, economic and recreational land use, human
population demographics, attitudes of the local population towards
wolves, and historic trends in wolf mortality need to be taken into
account.
Low standard roads (the ones that are not shown on county maps,
including Forest Service class D roads), and off-road motorized vehicle
trails (including all-terrain vehicles and dirt bike areas) and open
areas, are two access situations that were not adequately addressed, in
the Wisconsin Wolf Recovery Plan. Low road density correlates well with
wolf colonization because road density is directly related to levels of
human access. Impacts associated with trails and low standard roads are
difficult to measure, but probably have similar effects on wildlife
species such as wolves. The Wolf Advisory Committee recommends that
excessive development of low quality roads or trails for motorized
vehicles should be avoided and recreational trails should be placed with
care when in suitable wolf habitat.
3. Vegetation Management: Wolves require deer, beaver and other prey to
survive. Deer are generally most abundant in early successional
forests. Historically, disturbances such as windstorms and fires created
this vegetation condition, but in recent times timber cutting and other
forest management practices have provided this habitat. Beaver are
especially fond of aspen for food. Aspen, jack pine, and regenerating
forests of all types are preferred by deer. Oak is important to deer in
central Wisconsin, and seasonally throughout the state for its periodic
acorn crop. Dense conifer cover such as hemlock, cedar and mixed
conifer swamps are important as winter thermal cover for deer. Small
grassy upland forest openings are important components of deer summer
range. Wolf pack territories have a higher proportion of mixed
conifer-hardwood forest and forested wetlands than non-pack areas
(Mladenoff et al. 1995). Wolf territory size tends to increase as local
deer populations decrease, and territory size decreases when deer
numbers increase (Wydeven et al. 1995).
We recommend a balanced approach to forest management on public and
private lands to provide younger forest for prey species used by
wolves, while also maintaining some areas of older forest for other
species. Young forests provide summer habitat for deer and mature
conifer forests provide wintering areas. Young forests provide higher
populations of prey, and large blocks of low access forest provide
seclusion for wolves.
Forest management on large blocks of public forest lands should strive
to maintain a balance of forest age distributions to provide habitats
for wolves and other wildlife species.
4. Habitat Linkages and Corridors: Wisconsin is more fragmented with
roads, towns, and open agricultural land compared to northern Minnesota
and the Upper Peninsula of Michigan. To maintain a wolf population in
Wisconsin, it is important to provide forested habitat linkages and
corridors for wolf dispersal to and from Minnesota and Michigan, as well
as within Wisconsin. We recommend the maintenance of forested blocks of
land that connect wolf habitats across Wisconsin. The WDNR will
encourage private landowners and public land agencies to cooperatively
manage corridor habitats as part of the state's Managed Forest program.
Protection of corridor habitat should be a factor in considering
acquisition of public land for other conservation purposes.
5. Management of Den and Rendezvous Sites: Wolf pups are born in dens
in April and remain there until mid to late June. Dens may be excavated
in the ground, or may be hollow logs and stumps, old beaver lodges, or
rock caves. Wolf pups are moved to rendezvous sites in mid or late June
which are used until late September or early October when wolves begin
their nomadic hunting period of fall and winter. Rendezvous sites often
consist of grassy areas or sedge meadows near beaver ponds or forest
streams, often near dense conifer cover.
The Wolf Advisory Committee recommends the continued protection of den
sites and rendezvous sites in Zone 1 areas of suitable wolf habitat.
Areas within 330 feet (100m) would be recommended for total protection
from tree harvest and areas within 0.5 miles (0.8km) would be
recommended for protection from disturbance such as logging from March 1
to July 31. These recommendations would continue in Zone 1 areas both
during threatened listing and eventual delisting. Normally only one or
two den sites would be affected within a 50-square mile area.
To facilitate such protections state wildlife biologists responsible for
designating such sites and state, county and consulting foresters will
cooperate to best manage logging operations to protect the wolves while
facilitating forestry projects.
6. The Role of Wilderness and other Forest Reserves: Federal
wilderness (69 mi2, 5 areas), state wilderness (50 mi2) and other
non-timber managed forest reserves with limited or no motorized access
contribute to wolf habitat in that they provide refuge areas where
wolves are not subject to human disturbances. Although designated
wilderness areas are used by wolves, experience in Wisconsin and other
areas of the Great lakes have shown that managed forests with adequate
access management also provide suitable wolf habitat. Therefore it is
not necessary to designate areas as wilderness for the benefit of
wolves.
7. Alternate Habitat Management Considered: Other habitat management
alternatives were considered by the Wolf Advisory Committee. The
committee considered less emphasis on vegetative and access management
once wolves are delisted. Because public land agencies manage for a
variety of wildlife species, biodiversity protection, and sustainable
resource use (forestry, wildlife, fisheries, etc.), it is assumed that
such management should also provide habitat for wolves as long as wolves
are protected. The committee felt that special considerations for
wolves should continue into the future as wildland areas decline. Lack
of aggressive access management may expose wolves to higher levels of
mortality, and disturbance of den sites may displace wolves to less
suitable areas where pups are vulnerable to higher risks of mortality.
Secondary Wolf Habitat by Land Ownership {Click image for larger view}
|
We also considered more intense management of habitat for wolves. Such
recommendations might include increasing wilderness and other roadless
areas to provide additional wolf habitat. But large wilderness and
roadless areas without natural disturbance or timber harvest may lack
deer habitat, and would support only very low wolf densities. Creation
of large wilderness areas may cause local economic distress and could
create resentment toward wolves. Wolf monitoring in Wisconsin, Michigan
and Minnesota have demonstrated that wolves can survive well in more
intensely managed forest, and do not need to have large blocks of
wilderness set aside for them.
E. Wolf Depredation Management
BACKGROUND
Wolf depredation management is one of the most sensitive segments of
this Wolf Management Plan. WDNR is charged with protecting and
maintaining a viable population of wolves in the state, but also must
protect the interests of people who suffer losses due to wolf
depredation.
Wolves occasionally kill livestock, poultry, and pets. Although wolf
depredation is not anticipated to impact a significant portion of the
livestock growers, poultry producers, and pet owners, it can bring
hardship to individuals. Minnesota currently has more than 2,000 wolves
but fewer than 1% of the farms in wolf range experience wolf depredation
problems.
WDNR paid $38,340.90 in wolf damage compensation claims for 23 calves,
12 sheep, 140 turkeys, and 16 dogs during 1976-97. (See Appendix A.)
Depredation on dogs represented 78% of reimbursement payments provided
by WDNR. Only 0.3% of the farms in the current wolf range have
experienced wolf depredation problems. Three wolves have been
translocated as a result of depredations.
Reclassifying wolves from federally and state endangered to threatened
status will provide the option to euthanize depredating wolves. Public
comments in autumn 1996 revealed concerns about killing wolves,
particularly through public harvests. Most who supported euthanizing
depredating wolves felt this should only be done by government
professionals. Many urged educational programs and preventive efforts
by livestock producers to minimize depredation losses. There was strong
support for continued damage compensation programs.
Depredation Management Goal
The goal of the wolf depredation program is to minimize depredations and
compensate people for their losses.
Strategies and Procedures
The goal of the wolf depredation program is to minimize depredations and
compensate people for their losses.
Verification Procedures
Quick, uniform, and accurate verification of wolf depredation is
critical. Previous experience has shown that the majority of wolf
complaints turn out to be non-wolf problems when properly investigated.
Immediate response to complaints by qualified people is necessary to
reasonably determine cause of death.
A. Upon receipt of a possible wolf depredation complaint, WDNR will
immediately notify APHIS-WS agents responsible for investigating
complaints.
B. APHIS-WS will contact the complainant by phone within 24 hours and
make an onsite inspection within 48 hours of receipt of the complaint if
it appears to be legitimate.
C. APHIS-WS will classify the complaint under one of the following
categories:
- Confirmed Depredation. Clear evidence that wolves were responsible
for the depredation, such as a carcass present with bite marks and
associated hemorraging, wolf tracks in the immediate vicinity or other
wolf sign.
- Probable Depredation. Carcass missing or inconclusive but presence
of good evidence such as kill site, blood trails, wolf tracks and scat
in the immediate vicinity
- Confirmed Non-Wolf Depredation. Conclusive evidence that something
other than a wolf killed the animal. Wolf-dog hybrids and wolves that
appear to have been raised in captivity will be treated as domestic
animals.
- Unconfirmed Depredation. Any depredation or livestock loss that does
not meet the above criteria. This could be missing animals, animals
that died of other causes, and even animals killed by wolves but
unconfirmed because of lack of evidence.
The first two categories, "Confirmed" and "Probable" are the only ones
that will warrant further action. If the investigating APHIS-WS agent
classifies a depredation complaint as "Confirmed Non-wolf Depredation"
or "Unconfirmed Depredation", no further action will be taken except
that the incident will be recorded and, if the depredation is determined
to be caused by wild animals other than wolves, APHIS-WS will provide
the appropriate assistance.
Control Response Options
Four control response options are available to resolve confirmed or
probable depredations. The depredation management program will use a
combination of these options as appropriate depending upon the
individual situation. These include:
- Technical assistance to help prevent/minimize problems,
- Compensation for losses caused by wolves.
- Livetrapping and translocation of wolves causing problems.
- Trapping and euthanization of depredating wolves.
Under cases of "Confirmed Depredation" or "Probable Depredation", the
local WDNR Wildlife Biologist, the WDNR Regional Wildlife Expert, and
APHIS-WS will jointly determine appropriate management activities using
the following criteria:
A. Technical assistance will be provided in all Wolf Zones. These will
include abatement materials such as flashing lights, electronic guards,
and proven chemical repellents. This may also include development of a
depredation prevention plan for the farmer and recommendations for
increased abatement measures such as guard dogs or fencing which would
be cost-shared by WDNR.
B. Compensation will be provided in all Wolf Zones for verified and
probable losses of domestic animals to wolves while they are listed as
threatened. The present compensation program is funded through
Endangered Resources revenues. Following delisting, compensation for
damage done by gray wolves will no longer be available. The WDNR will
seek sources for funding the compensation program when wolves are
delisted so that this program can be continued. Farmers must follow any
technical assistance recommendations to remain eligible for
compensation payments. Damage appraisals will continue to be performed
by APHIS-WS to provide accurate, timely and fair compensation for
losses.
C. Translocation and euthanization Wolves may be translocated from
private lands in Zone 1 and in Zone 2. Wolves may be euthanized in
private lands in Zone 1, in Zone 2, and in Zone 3 (Table 2).
Translocation may be effective at reducing future depredation problems
in certain cases. Eventually translocations may be limited by the number
of suitable release sites in Zone 1 as sites become occupied by wolves.
Identification of suitable release sites and agreements with appropriate
land owners/ managers must be done before translocation efforts can be
initiated.
Some wolves may be euthanized in the future due to conflicts with
humans. This option can be used when:
- there have been significant documented, confirmed losses at a site,
- the producer has a signed depredation management plan for the farm
and follows abatement/husbandry recommendations,
- the APHIS-WS Depredation Specialist recommends euthanasia, and the
WDNR approves.
- Wolf-dog hybrids will be euthanized in any zone where they are
captured at depredation sites.
Initiation of translocation and/or euthanization efforts will depend
upon the Wolf Zone in which the depredation problem occurs and the
status ("threatened"; delisted) of the wolf population. Guidelines for
each Wolf Zone are as follows:
- Zone 1a - No translocations or euthanizing of wolves will be
undertaken in this zone.
- Zone 1b - Trapping efforts will be initiated only in cases with
chronic depredation problems while wolves are still listed as state
threatened. Trapping will be limited to areas within 0.5 miles of the
depredation site, and most wolves captured will be translocated into
Wolf Zone 1a. Wolves will be euthanized only under extreme
circumstances as described above or when suitable translocation sites
are limited in Wolf Zone 1a. After wolves have been state delisted,
proactive trapping may be initiated before problems begin at depredation
sites which have had a history of reoccurring problems.
- Zone 2 - Trapping efforts will be limited to severe depredation
problems and to areas within 5 miles of the depredation site while
wolves are still listed as state threatened. Wolves captured will be
translocated into Wolf Zone 1a if there is a need for additional wolves
in areas within that zone. Wolves will be euthanized if there are no
suitable translocation sites. Special consideration will be given to
allow movements of wolves between Central and Northern Wisconsin. After
wolves have been state delisted, proactive trapping may be initiated as
described above, the maximum distance trapping from the depredation site
(5 miles) may be eliminated, and private landowners or their agents may
be given permits to destroy depredating wolves.
- Zone 3 - Only APHIS-WS agents, with WDNR approval, will be allowed to
trap and destroy wolves causing problems while they still are listed as
state threatened. Trapping for problem wolves will be allowed anywhere
within Zone 3. After wolves have been state delisted, proactive
trapping may take place, local authorities may be allowed to destroy
wolves, and private land owners or their agents may be given permits to
destroy depredating wolves.
Table 2 - Wolf Depredation Management Options by Management Zones.
{Click image for larger view} |
Table 2 shows the depredation control management options within each
wolf management zone. The same management options will apply to wolves
under state threatened and delisted classifications. Although
translocation and euthanization are listed as depredation management
options everywhere except on public lands in Zone 1, these practices
will be used only as a last resort. Depredation management will focus on
prevention and mitigation rather than wolf removal. This could include
cleaning up ""carcass dumps" frequent checks on livestock, birthing near
farm buildings or in corrals, and avoiding placing young livestock in
wooded pastures. It may also be necessary to include neighboring farms
in some cases. Poor husbandry practices on one farm could result in
depredation problems on nearby farms. Wolf removal without adequate
prevention and mitigation will likely result in large annual
expenditures of time and money. This could cause farmers with recurring
problems to doubt the adequacy or competency of the agencies involved.
F. Wolf Education Programs
Public education about wolves was a major factor in the success of wolf
recovery in Wisconsin. Education emphasized greater acceptance of
wolves and have reduced unfounded fears and myths. Education about
wolves will continue to be important in future wolf management, with
more focus on ways to live with wolves, needs for wolf control activity,
and needs for more of an understanding of the role of wolves in forest
ecosystems. Educational information will also be needed to explain the
reclassification and delisting process to the general public as wolves
pass through threatened and delisted status.
A multifaceted and multi-agency approach will be used to encourage wolf
education in Wisconsin. Some of the major education steps are listed
below.
1. Develop Special Education Materials:
a. The current (1996) edition of the "Timber Wolf Life Tracks"
publication will be updated about every 5 years or when major changes in
status or population occur.
b. A pamphlet will be developed between WDNR and APHIS-WS on means for
livestock owners to reduce or avoid depredation problems by wolves and
other predators.
c. Develop a booklet that explains the Wisconsin wolf management to
general audiences.
d. Periodically write and publish news releases and articles on
Wisconsin wolves for state newspapers, magazines, and others include the
"Wisconsin Natural Resources Magazine".
e. Incorporate information on wolf identification, protection, and trap
release methods in hunting and trapping pamphlets, and incorporate wolf
identification/ecology information into hunter and trapper education
courses.
f. Incorporate wolf information on the WDNR's Web Page
(www.dnr.state.wi.us)
2. Work with other organizations:
WDNR will continue to work with other organizations to promote wolf
education including: Timber Wolf Alliance (TWA), Timber Wolf
Information Network (TWIN), International Wolf Center, and other
organizations involved in promoting wolf education. The WDNR will
provide a person to serve on the advisory committee for TWA, provide
training at TWA workshops, review and edit educational material for TWA,
and help TWA promote the annual "Wolf Awareness Week". The WDNR will
assist TWIN with workshops when requested and provide survey information
for TWIN to use in developing educational materials. Periodic updates
on Wisconsin wolf status and management will be provided to the
International Wolf Center.
WDNR will assist other wolf organizations, schools, colleges, and
educational organization to teach members about wolves and assist in
developing wolf education material.
3. Provide Special Training:
As wolf populations continue to expand, and wolf management becomes more
decentralized, there will be more of a need to teach others about wolf
management including WDNR wildlife biologist and technicians, other WDNR
field workers, other agency personnel and tribal members. Education on
wolf management would include: identification of wolves and wolf sign,
methods of determining local wolf populations, methods of trapping and
releasing wolves, procedures for wolf habitat management, and means for
reducing wolf depredation problems. The WDNR will develop and conduct
such programs to teach others about wolves. Other programs in which
WDNR wolf program personnel will be involved would include training for
APHIS-WS trappers, and track training for WDNR, Great Lakes Indian Fish
and Wildlife Commission (GLIFWC), tribal members, Forest Service, and
other agency personnel conducting furbearer and carnivore surveys. WDNR
wolf program personnel will assist in the training of university
personnel conducting wolf studies on methods of trapping, handling and
monitoring of wolves.
4. Provide general wolf presentations:
The WDNR wolf program coordinator will continue to provide presentations
to the general public on Wisconsin wolves, as will others working on the
wolf program. But as wolves become delisted and wolf management becomes
more decentralized, no one individual will be as intensely involved with
the wolf program. Therefore the need to give wolf presentations should
be shared more broadly with other WDNR wildlife biologists, park
naturalists, other agency biologists, and trained volunteers.
G. Law Enforcement
Strict legal protection has been a key in the improved status of wolves
in Wisconsin and the Great Lakes region. In Wisconsin, important
factors in the increase of wolves has been the closing of coyote hunting
across the northern half of the state during the firearm deer hunting
season, increased fines for killing of endangered species, and vigorous
investigation of illegal killing of wolves. Changes and potential
regulations for necessary reclassified and delisted wolf populations are
listed below:
1. Threatened Status Regulations
a) The term "threatened species" needs to be added to Wisconsin Stats.
29.65 (civil actions for damage caused by law violations), and 29.9965
(wild animal protection assessments). These statutes would set the
value of an illegal killed wolf at $875, the value set for all
endangered species, but currently not including threatened species.
This amount would be added to the penalty for illegal killing of a wolf
upon conviction.
b) Penalties for killing threatened species remains the same as for
endangered species, that being (Wisconsin Stats. 29.415 (5) (a) (1)):
Unintentional violations would be subject to a fine of $500 to $2,000
and 1 year loss of hunting privileges. Intentional violations would be
subject to a fine of $2,000 to $5,000 or up to 9 months in prison, or
both, and loss of hunting privileges for 3 years.
c) A state endangered or threatened species permit would be required for
possessing of captive wolves.
d) Coyote-closed zones during the gun-deer season would be modified to
cover zone 1 (Figure 7), and would reduce areas with restricted coyote
hunting from 44% to 41% of the state.
e) While wolves remain federally listed as endangered or threatened, all
law enforcement work will be coordinated with the USFWS. Decisions as
to whether to prosecute violations as state or federal will be made by
federal and state wardens in consultation with the local district
attorney. Generally, federal violations carry much heavier fines and
longer periods of imprisonment.
2. Delisting Regulations
a) The wolf should be added to the animal list in Wisconsin Stats. 29.65
(1) (6) and 29.9965 (1) (6) (2). It would be added to moose, elk,
fisher, prairie chicken, and sandhill crane as animals valued at $262.00
for illegal kills.
b) The wolf should be added to the list of species for which unlawful
hunting would result in a "forfeiture of not less than $1,000 nor more
than $2,000 and revocation of hunting privileges for 3 to 5 years" which
currently exits for moose, elk, bear, and deer.
c) Additional regulations should be added to Chapter 29 making it
illegal to possess either wolf or wolf-dog hybrids in captivity without
obtaining a permit from the WDNR. Legislative authority should be sought
for Conservation Wardens to destroy free-roaming wolf-dog hybrids in
wildland areas.
d) Wolves would be added to Wisconsin Administrative Code NR 10.02 (1)
as a "protected wild animal".
e) A coyote-closed zone would be maintained during the gun-deer season
in Zone 1.
f) Investigations of illegal killing of wolves would be done by
Wisconsin conservation wardens or tribal wardens, and federal
involvement would not occur unless transport of illegally killed wolves
crosses state lines.
g) Wolf dens would be included under the category of regulations against
disturbing or molesting in Wisconsin Administrative Code under NR
10.13(2) and create a new subparagraph "(d) Molest or disturb any gray
wolf den".
H. Inter-Agency Cooperation/Coordination
Our effort to achieve a population of 300-500 wolves with our ultimate
goal to delist the gray wolf in Wisconsin requires the continued
involvement and cooperation among many agencies, private individuals
and organizations. The Wolf Advisory Committee recommends that the
WDNR continue to mesh its objectives with those in the USFWS Recovery
Plan (1992), Minnesota DNR, Michigan DNR, Wisconsin counties, industrial
forests, tribes and other concerned agencies and organizations.
In 1992 a Wisconsin Wolf Advisory Committee was formed similar to other
species advisory committees coordinated by the WDNR. The wolf advisory
committee is charged with reviewing and making recommendations on
policies and management procedures affecting wolves. the current
management plan was developed by the wolf advisory committee. Advisory
committee membership includes WDNR, USFWS, U.S. Forest Service, GLIFWC,
County Forests, University of Wisconsin-Stevens Point, APHIS - WS, and
Wisconsin Conservation Congress. The committee will continue to meet
regularly once the plan is approved to review and monitor progress.
Committee meetings are open to the general public and other agencies.
Since 1989 Great Lakes wolf stewards (an informal group of state, U.S.
Fish & Wildlife Service and U.S. Forest Service biologists working with
wolves) has met during most years to discuss wolf management issues
affecting the Great Lakes region. This group consists of
representatives from various agencies and private organizations from
Michigan, Minnesota, and Wisconsin. The GIS analysis of wolf habitat in
the Great Lakes region (Mlandenoff et al. 1995) and guidelines for wolf
management in the Great Lakes region (Fuller 1995) are two products that
resulted from these meetings. The WDNR will continue to promote,
support and occasionally sponsor Great Lakes wolf stewards meeting.
The chair of the Wisconsin Wolf Advisory Committee and the U.S. Forest
Service representative also serve on the Federal recovery team for the
eastern population of gray wolves in the U.S. This committee is
reviewing the 1992 recovery plan to determine if reclassification and
delisting criteria are being met. The Wisconsin members serve on the
federal recovery team with members from Michigan, Minnesota, Wisconsin
Chippewa tribes, and the National Park Service. This committee will
finalize recommendations for federal delisting in close cooperation with
the states.
Once wolves are state delisted, the Wisconsin Wolf Advisory Committee
will continue to meet at least once per year to review wolf management
in the state. Wisconsin biologists will meet periodically with
biologists from Michigan and Minnesota to coordinate wolf management
especially maintenance of habitat corridors that connect wolves across
the three states.
I. Program Guidance and Oversight
A Wolf Advisory Committee will continue to oversee state wolf management
in Wisconsin. The Wisconsin Wolf Advisory Committee reports to the
Bureau of Endangered Resources Director and Division of Lands, Land
Leadership Team of the Department of Natural Resources. Plans prepared
by the Wolf Advisory Committee are subject to approval of the Natural
Resources Board. The chairperson of the wolf advisory committee will be
the coordinator for wolf management activity in the state. Composition
of the Wisconsin Wolf Advisory Committee should consist of the
following:
a) The chairperson should be the mammalian ecologist in the WDNR
Bureau of Endangered Resources or, if the species is listed as a
furbearer, the WDNR furbearer ecologist in the WDNR Bureau of Wildlife
Management.
Other members should include:
a) WDNR wildlife biologists from each region that have wolves,
b) WDNR wildlife education specialist,
c) WDNR wildlife depredation specialist,
e) WDNR wildlife health specialist,
f) WDNR conservation warden,
g) APHIS-WS,
h) USFWS biologist,
i) USFS biologist,
k) tribal biologists,
l) WDNR mammalian research ecologist,
m)WDNR public affairs manager,
n) Conservation Congress representative,
o) a County Forest Administrator,
p) WDNR Furbearer Ecologist, and
q)GLIFWIC biologist.
The committee can also include other cooperators from private and public
agencies as are needed.
The Wolf Advisory Committee should meet at least once per year to assess
the state wolf population, assess wolf management zones, review
depredation control activities, assess impact of educational activities,
assess needs for additional control activity, review problems and
determine needs for new policies or management procedures. At 5 year
intervals, a thorough review should be made of the state wolf population
status, and a public review should be made to assess concerns and
support of wolf management.
J. Volunteer Programs
Many people have volunteered for wolf recovery efforts since the
development of the Wisconsin Wolf Recovery Program in the 1980's.
Volunteers have assisted in education programs, population monitoring,
and financial donations to wolf management. Such efforts have expanded
levels of wolf recovery work, provided additional funding, and helped
foster citizens that are very committed to wolf recovery. As the wolf
population expands, and are reclassified to threatened and eventually
delisted, greater reliance will be placed on volunteers to conduct wolf
conservation activity.
Timber Wolf Alliance (TWA) was formed in 1987 as a means for involving
private citizens into Wisconsin wolf recovery efforts. The Sigurd Olson
Environmental Institute out of Northland College, Ashland, Wisconsin
sponsors TWA, in a similar fashion as it has sponsored Loon Watch, a
successful program for volunteer monitoring of loon populations in the
Great Lakes. TWA has developed a speakers bureau of volunteers that
give wolf talks and assist at wolf education programs at sports shows
and other events. TWA also has an Adopt a Pack program which provides
education to groups and donates part of those proceeds from the program
to DNR wolf population monitoring efforts.
Students of Northland College and UW-Stevens Point have monitored
wolves. Students monitor wolves through snow tracking, howl surveys,
and radio-tracking. Programs such as these can continue, and could
expand to include universities, technical college and high schools.
Timber Wolf Information Network (TWIN) was formed in 1990 to encourage
wolf recovery through wolf education programs. TWIN provides a wolf
ecology course through which many people have been taught about wolves.
TWIN also has an Adopt a Pack program to teach schools and youth groups
about wolves and encourage wolf research. Volunteers trained through
TWIN's workshops have assisted on wolf population monitoring efforts in
the state.
The WDNR initiated a volunteer tracking program in 1995, to use trained
volunteers to search for wolves in winter and assess abundance of other
medium and large carnivores in Wisconsin. Forested portions of north
and central Wisconsin were delineated into 123 survey blocks averaging
200 square miles each. Volunteers are requested to conduct 3 or more
good snowtracking surveys covering about 30 miles of snow covered roads
each on their survey block each winter. This program is being evaluated
for its effectiveness in counting wolves.
Volunteers may eventually be responsible for conducting much of the wolf
tracking in Wisconsin, perhaps through organizations like TWIN or TWA..
The DNR will continue to encourage volunteer programs working with
wolves.
Opportunities for volunteers to work directly with WDNR wolf workers are
limited, therefore WDNR will continue to work with other organizations
and develop the volunteer tracking program. The WDNR will continue to
search for other opportunities for volunteer involvement.
Work with volunteers will also be important in developing methods for
preventing depredation and providing factual information to members of
the public about wolf behavior.
It may be desirable to enlist a volunteer organization to fund wolf
depredation claims once delisting occurs and WDNR endangered species
funds are no longer available.
The alternative to using volunteers would be to continue intense
involvement by WDNR and other agencies in all aspects of wolf recovery
and conservation. As the wolf population increases and funding declines,
it will not be possible to maintain existing levels of wolf conservation
efforts. Involvement of volunteers will be essential for the long-term
success of wolf conservation in Wisconsin.
K. Wolf Research Needs
The WDNR has been monitoring the status of the wolf population in the
state since 1979. Emphasis has been placed on determining population
status, pack sizes and distribution, mortality rates and factors,
productivity, rates of recolonization, dispersal behavior, and
disease/health status. More intensive research was initiated in 1992 in
extreme northwestern Wisconsin to determine the impacts of highway
expansion on resident and dispersing wolves near U.S. Highway 53.
Results of these efforts have provided excellent data for tracking the
progress of Wisconsin's recovering wolf population.
Reclassifying of wolves from "Endangered" to "Threatened" status, and
hopefully down to "Protected" status in the future will require
additional research to safeguard the wolf population and
develop/evaluate future wolf management practices. Future wolf research
needs include:
- Development of reliable, but more economical wolf census techniques
to accurately document numbers and distribution.
- Re-measurement of public attitudes towards wolves and recovery in the
state to define reasonable wolf population goals and acceptable wolf
habitat.
- Identification of wolf travel corridors and development of
appropriate management practices for travel corridors to allow continued
interchange of wolves among Minnesota, Wisconsin, and Michigan.
- Development of a model that can predict potential den and rendezvous
sites within suitable wolf habitat so these areas can be protected from
human disturbance.
- Continued health monitoring to identify factors causing low pup
survival and to document any future outbreaks of diseases or parasites
that may have significant negative impacts on the wolf population.
- Development of policy/procedures for handling depredating wolves and
explore possibilities to minimize depredation problems.
- Identification of factors apparently limiting wolf colonization in
northeastern Wisconsin
- Conducting special long-term research on wolf ecology, population
growth, and depredation concerns in central Wisconsin.
- Documentation of the impacts of future wolf populations on deer,
beaver, coyote and other wildlife within our wolf range.
- Conduct research on nonlethal means of reducing wolf depredation and
thoroughly examine the ecology of depredating wolves.
- Developing models that estimate the state wolf population using
existing survey and population data, as well as identifying needs for
additional surveys. Use modelling to further examine viability of the
state wolf population.
Availability of funding and personnel will determine the rate at which
these research needs will be met. Other research priorities may arise
with changes in wolf populations, human development, and land management
practices. Some research would be conducted by WDNR, universities and
other cooperators. Attempts will be made to secure outside funding to
allow more thorough research than possible under current funding.
L. Wolf-Dog Hybrids and Captive Wolves
A wolf -dog hybrid is the offspring of the mating of a wolf (Canis
lupus) with a domestic dog (Canis familiaris). Normally these are bred
in captivity because wild wolves rarely breed with dogs. These animals
have rapidly grown in popularity in the late 1980's and 1990's and seem
to be the pet of choice for a growing segment of the public that wants a
pet that is different, intelligent, semi-wild, and independent. The
macho characteristics of wolf/dog hybrids make them highly desirable to
some people but also highly unpredictable. Estimates of the number of
privately owned hybrids in this country run as high as 400,000 (Hope
1994).
The "predatory behaviors" of wild predators like the grey wolf have been
lost in domestic dogs. However, in hybrids these instincts are present
to varying degrees yet the animals commonly lack a fear of humans.
Attacks, maulings, dismemberments and deaths caused by wolf/dog hybrids
have received national media attention. Four children are known to have
been killed by hybrids between 1981 and 1988. The death of a four year
old in Florida in August of 1988 seemed to heighten media attention on
this subject. In this case a publicly trusted institution--an animal
shelter--featured a hybrid as the "pet of the week". Two hours after
the animal had been brought to it's adoptive home, it killed the
neighbor's child. The shelter paid a $425,000 settlement to the boy's
family. This tragedy set a national precedent for animal
shelters/agencies: wolf/dog hybrids are to be put down or returned to
their original owner but are not to be adopted out to an uneducated,
unsuspecting public.
This precedent makes it very difficult for distressed owners of
unmanageable adult wolf/dog hybrids to find a "good home" for the animal
they still love but just can't live with anymore. There are numerous
wolf and wolf/dog hybrid shelters throughout the country. At this time
they are all totally full. Unfortunately for the animals and the
reputation of wild wolves, many overwhelmed hybrid owners resort to
"setting their wolf free" when they cannot find a suitable home for
them. These freed hybrids however lack the hunting skills and pack
structure needed to survive by hunting wild prey. When these animals
become hungry they instinctively return to humans for food, invariably
get into trouble and often are shot to death by local enforcement
officers. There have been eleven cases of free-roaming wolf/dog hybrids
in Wisconsin between 1989 and 1996 (see Appendix G).
In addition to being inhumane, the release of hybrids and the problems
they cause gives wild wolves a bad reputation.
Wildlife biologists also worry about escaped or released wolf/dog
hybrids interbreeding with wild wolves--diluting their gene pool with
the instincts and behaviors of domestic dogs (Hope 1994). Dog genes
in a wolf population may reduce long term viability and increase rates
of livestock depredation.
Proposed Regulations
Attacks on humans by captive wolves and wolf/dog hybrids will continue
to contribute to a negative image of wolves to the public.
Additionally, released/escaped hybrids have the potential of destroying
the genetic purity and hence, the legal status, of wild wolves in
Wisconsin.
Possession of pure wolves is presently allowed only by WDNR permit.
While this species is listed as Endangered or Threatened the WDNR Bureau
of Endangered Resources is responsible for issuing such permits. These
permits can only be issued for "zoological, educational, or scientific
purposes or for propagation for preservation purposes" (s. 29.415 WI
Stats.). The Wolf Advisory Committee recommends that the possession of
wolves should continue to be highly regulated following delisting. The
WDNR should promulgate specific Administrative Rules to ensure this.
Possession of wolf/dog hybrids also needs to be regulated due to their
potential impact on wild, free ranging wolves. The WDNR should seek
statutory authority to regulate the ownership of these animals in the
state. Twenty-five other states presently regulate the possession of
these animals; these regulations range from simple registration to a
total prohibition of possession.
Free-roaming wolf-dog hybrids trapped at depredation sites will be
euthanized unless collars provide the identification of an owner. The
owner of such an animal may be responsible for the cost of depredations.
Legislative authority may be sought to allow Wisconsin Conservation
Wardens to destroy free-roaming wolf-dog hybrids. Local law
enforcement officers may kill animals which cause a substantial risk or
threat to human life by attack or aggressive behavior.
M. Wolf Specimen Management
To date wolf carcasses found in the wild have been necropsied to
determine cause of death and health status. While wolves are listed as
endangered, the DNR policy has been to have all wolf carcasses
necropsied by the National Wildlife Health Lab in Madison, Wisconsin.
Eventually all become specimens at research institutions, with most wolf
specimens deposited at the University of Wisconsin - Zoology Museum in
Madison. When wolves are reclassified, and eventually delisted, the
management of wolf specimens should be modified. The Wisconsin Wolf
Advisory Committee developed guidelines for managing wolf specimens
under threatened and delisted classification.
- Wolf Specimen Management - Threatened
With reclassification to threatened, research, population monitoring
and health evaluations of dead wolves found in the wild will remain the
top priority. Additional wolf carcasses will be made available as
euthanasia of depredating wolves become possible, and accidental
mortality caused by vehicle collisions increases. All wolf carcasses
will be necropsied by the National Wildlife Health Lab, and specimens
will be turned over to interested research museums when there is an
identified need and use for such specimens. If specimen remain
available after research needs have been met, the second priority for
use of wolf carcasses would be education purposes. Such carcasses can
be made available to nature centers, state parks, wolf education
organizations, DNR and other agency offices, and tribal centers.
Carcasses would not be available for private ownership.
Wolves found dead in the field should be collected by wildlife
biologists, wildlife technicians or conservation wardens and placed in
DNR freezers until arrangements can be made to ship the carcasses to
Madison. Any wolves euthanized by USDA-APHIS - Wildlife Service will
also be turned over to DNR for necropsies. All carcasses should be
tagged, and labeled with all pertinent information kept with each
carcass. The WDNR regional wildlife expert should be notified of all
wolf carcasses found in his/her region. The wildlife specialist will
coordinate shipment, necropsies, and eventual designation of specimens.
Regional wildlife experts will keep lists of organizations interested in
receiving carcasses, and will coordinate distribution of carcasses.
Reports will be submitted at the end of each year to WDNR - Endangered
Resources by regional wildlife experts on carcasses collected, and final
disposition of each. Any wolf suspected of being killed illegally will
be held for conservation wardens until legal investigation and
prosecution are completed.
- Wolf Specimen Management - Delisted
When wolves are no longer listed as threatened or endangered in
Wisconsin, ownership of wolf carcasses can be broadened in Wisconsin.
Within the Chippewa Ceded Treaty areas of northern Wisconsin, a portion
of the wolf carcasses may be requested by tribal members. Wolf
carcasses would be available from depredation control activities,
natural mortality, illegal kills, and accidents.
Research will continue to be an important priority, but will require a
research proposal identifying needs and anticipated results, and such
proposals would need WDNR and/or tribal approval. A portion of
carcasses collected each year may be requested by WDNR-Wildlife Health
specialist to evaluate health status, and all skinned carcasses may be
requested most years. Following research and health monitoring, wolf
education would be the next priority for ownership of wolf carcasses.
Skins and skulls would be made available for schools, nature centers,
state parks, WDNR and other agency offices, tribal centers, wolf
education organization, and qualified wolf educators. Wolf specimens
could be turned over to private individuals if specimens are not needed
for research or education, or carcasses are likely to spoil before they
can be transferred to others. A portion of specimens may be requested
by tribal members in Ceded Territory. No carcasses should be provided
to landowners conducting control on their land, or to persons involved
in accidental killing of wolves. Dead canids suspected of being
wolf-dog hybrids, but appear to be mostly wolf, should be treated as
wolves for the purpose of wolf specimen management.
Regional wildlife experts will coordinate wolf specimen management in
each WDNR region. The wildlife experts will maintain lists of
organizations and individuals interested in receiving specimens, and
will determine disposition of carcasses. Annual reports will be
submitted to WDNR Endangered Resources on carcasses collected and
handled in each region, including biological information and final
disposition of carcasses.
N. Ecotourism
Ecotourism has developed in recent years as a means for obtaining
financial benefits from natural ecosystems and wild animals, while also
encouraging protection of wildlands (Hunter 1996). Ecotourism at times
can be a double-edged sword; it may encourage protection and
conservation of biological diversity, but at times could cause
disturbance of wild animals and disruption of their habitats.
Guidelines and occasional regulations may be necessary to prevent or
minimize negative affects of ecotourism.
Wolves can at times contribute to ecotourism. In Ely, Minnesota,
tourist visits to the International Wolf Center provide a $3 million
annual impact to the local economy (Mech 1996). Ecotourism dealing with
wolves is not likely to be as profitable in Wisconsin, but there are
means that ecotourism involving wolves could impact local economies.
Howling sessions could potentially be conducted by tour guides across
portions of northern Wisconsin. Tours of wolf territories to search for
wolf sign could be done during winter months. Snowmobiling and ATV
tours of wolf territories have been suggested for the Minocqua area.
Volunteer or paid naturalist at resorts could include wolf programs and
tours of wolf territories. Naturalist programs by WDNR, Forest Service
or National Park Service could attract tourist use of surrounding areas
by providing wolf programs. Persons attending wolf workshops at
Drummond and Tomahawk, make use of restaurants, taverns, gas stations
and convenient stores in the local areas.
Ecotourism could also potentially have negative impacts on wolves in
Wisconsin. Excessive howling sessions could cause abandonment of
preferred rendezvous sites, and perhaps displace wolves to less suitable
areas where they may be exposed to more mortality or cause depredation
problems. Howling sessions may cause energy drains on adult wolves
constantly returning to rendezvous site to protected pups, while
abandoning their hunts. Disturbance of den areas may cause premature
abandonment of den sites, and may expose pups to mortality; wolf pup
mortality is already fairly high in Wisconsin. Frequent disturbance of
wolves at kills may become energy costly for wolves. Frequent
disturbance at rendezvous site may also display wolves.
The Timber Wolf Alliance and Timber Wolf Information have developed
guidelines for minimizing impact from howl surveys on wolves. These
guidelines include: avoid howling during the denning period in
April-June, limit howls in specific territories to once per week or
less, avoid repeated howlings at individual wolf packs, and refrain from
visiting rendezvous sites. Similar guidelines would be recommended to
others planning to conduct wolf howls in Wisconsin. Encouragement would
be made to groups conducting wolf tours or howl sessions to minimize
impact on wolves, avoid certain portions of wolf territories, and
refrain from excessive visits to wolf areas. It would also be
recommended to any groups conducting such tours that these be conducted
by individuals knowledgeable in wolf ecology and behavior. It may be
necessary in the future to regulate wolf tours done for profit, in a
fashion similar to existing guide permits.
