Are there twice as many wolves running around parts of Washington as WDFW’s minimum count suggests?
It seems more likely in the wake of a state Senate committee work session on the species Tuesday afternoon.
Information from it is giving Washington wolf world observers a chance to compare WDFW’s figures for parts of two northeastern counties with how many wolves that dung dog-gathered data says were actually there at the time.
Dung dogs would be canines that the University of Washington’s Dr. Samuel Wasser et al have trained to find scat. They’re so good that they can smell Puget Sound orca ordure a mile away, Wasser told senators.
On dry land between April 2015 and February 2016, they helped researchers sniff out 4,685 piles of poo in wild portions of Pend Oreille and Stevens Counties.

Their survey area that season overlapped the territories of the Smackout, Dirty Shirt, Carpenter Ridge, Goodman Meadows and Skookum Packs.
With 3,917 of the samples subsequently analyzed in the lab so far, 1,878 (48%) were determined to be coyote crap, 714 (18%) to be bobcat BMs, 541 (14%) to be wolf waste, 323 (8%) to be black bear brownies and 212 (5%) to be mountain lion leavings.
What the remaining 7 percent was wasn’t clear, but the scat not only told researchers what species excreted it (as well as what they’d been, er, wolfing down), but also allowed them to genetically identify the specific animal from whose alimentary canal it exited.
While counting wolves has been an inexact science up to this point, Wasser told members of Sen. Kevin Van De Wege’s Agriculture, Water, Natural Resources & Parks Committee they were able to determine that those 541 wolf samples were left by 60 different individual wolves.

He said his abundance estimate for the area between spring 2015 through midwinter 2016 was 68.
Now, it’s not quite apples to apples, more like apples to pears, but that timing does allow us to compare his findings with some from WDFW’s 2015 year-end count, which came out in early 2016.
The state agency estimated that the packs that left all that poop numbered at least 30 wolves — eight in Smackout, eight in Dirty Shirt, two in Carpenter, seven in Goodman and five in Skookum.
Thirty is, I want to stress, a minimum number, the confirmed headcount, but it is also a lot fewer than 60, let alone 68.
Hunters and others have long suspected that there are more wolves running around than WDFW’s minimum, and the evidence collected by scat-sniffing dogs from just one part of the state, albeit a wolf-heavy one, seems to bear that out.
So how might the state agency explain such a big numerical difference?
Partially it’s that this is a different, more precise way to count wolves than how WDFW has had funding to do it — collaring wolves and trying to find them and their packies later on.
But some of Wasser’s 60 known animals could have been pups born in spring 2015, defecated all over, but didn’t survive to the end of the year to be counted during the state’s aerial surveys.
They could have been dispersers from elsewhere that, say, ate a 49 Degrees North deer/moose/elk/cow/bird/rodent/snowshoe hare/etc., left a dropping or two and continued on their journey out of the area.
They could have been born to one of the packs, learned how to hunt and subsequently dispersed before biologists buzzed around that winter in the Cessna.
They could have been poached — state game wardens did find evidence that a man illegally killed at least two members of the Goodman Meadows Pack prior to a March 2016 search warrant on his cabin.
And it’s possible that at least three if not more of WDFW’s nine listed known lone/miscellaneous wolves in the greater Eastern Recovery Zone at the end of 2015 were in this area during the survey, so it’s the known 30 plus that many more.
Still, it’s eye-opening, and what’s more Wasser also told senators that during the following field season his dogs found evidence of at least 92 wolves in the same area, and he estimated there were 95 there then.
He said that between the two sessions of fieldwork, they found evidence of 114 unique wolves there.
The bottom line?
Later this winter WDFW will release its 2018 year-end minimum count. That figure is likely to be a lot higher than 2017’s 122, and it may also include new packs from a whole new area of Washington.
While state wolf managers have yet to confirm there are any wolves in the South Cascades, thanks to legislative funding, last year Wasser’s dogs found potential evidence in northwestern Yakima County and multiple parts of Skamania County.

Those feces are now undergoing final analysis with results expected soon, but if “potential wolf” droppings the dung dogs found in the known Teanaway Pack territory are any indication, it seems possible there may be a pack or two in the South Cascades.
Yes, wolves, wolf impacts and wolf people are pains in the ass to manage, but having four successful breeding pairs there is important to reaching the recovery goals that begin statewide delisting processes, and the sooner that occurs the better.
Well, the better for everyone except the groups that are trying to keep the species under kid-glove management, including through an upcoming court case against WDFW.
But this new data strengthens the argument that there are far more wolves in Washington, they’re likely far more widespread and they’re far, far more resilient than Arizona’s Center for Biological Diversity etc., want you to know.
