No wolf population growth and almost no livestock depredations-
The 2013 official Washington State wolf report is out today. It shows a very slight population increase from 2012 — from 51 to 52 wolves. Because random effects loom so large in small populations, it is most reasonable to call the situation “no growth,” “stable.”
Because there is often a lot of shouting about actual or suspected wolf depredations on livestock and pets, 2013′s numbers show a case for silence on the matter. Only one cow calf died from wolves and none were injured. Three dogs sustained injuries from wolves.
Washington wolf packs were less productive than average for wolves in the Western U.S. with an average litter size of just 2.4 wolves. Packs were small with a mean of 3.8 members. Thirteen wolf packs were identified, and five of them had what are considered to be “breeding pairs.” Washington wolf populations are evaluated in three areas — Eastern Washington, North Cascades, and South Cascades/Coastal Washington. All of the wolves were in Eastern Washington (10 packs), or the North Cascades (3 packs). Of the Eastern Washington wolves, all were clustered up in Northeastern Washington.
One pack was interstate – Idaho-Washington. This is the Diamond Pack. With 9 members, it is the largest of all the Washington State wolf packs. Two packs lapped into British Columbia — the Salmo at 4 wolves and the Wedge at just two wolves. Both Salmo and Diamond were breeding pair packs. Other breeding pair packs were the Lookout, the Teanaway, and the Huckleberry.
We earlier posted a report on Oregon wolves in 2013. Later we plan stories on Idaho, Montana, and Wyoming wolves in 2013. Their official 2013 reports were released today.
