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.

    For those who speculated there would be a Washington State wolf population explosion, these figures compared to the previous year tell us that it isn’t likely.

      So why not a larger population increase? interesting to note one pack, the Diamond Pack is Idaho -Washington interstate.

      I understand tracking livestock deaths as political reality but hard to swallow pet deaths. Should pet deaths be a consideration in managing predators, I think not.

      anyhow why do you think such a small increase?

        I had read that the wolf number was likely in the 120 range but actual individual wolves that could be positively confirmed number of 52.
        I think the 100 + is more accurate, the number of pack, BP, and population grow each year.

    Interesting – I like that there were almost no livestock depredations either. Good for Washington!

    Hey, where is your planned story on wolves in Utah? Huh??

    Oh, right, our wolves either get shot and buried or run out of the state.

‎"At some point we must draw a line across the ground of our home and our being, drive a spear into the land and say to the bulldozers, earthmovers, government and corporations, “thus far and no further.” If we do not, we shall later feel, instead of pride, the regret of Thoreau, that good but overly-bookish man, who wrote, near the end of his life, “If I repent of anything it is likely to be my good behaviour."
