GRAY WOLF
There were 13 survey areas that followed our species-specific protocols for detecting gray wolves, and all but four
were located south of I-90 (Figure 4). Our monitoring efforts dedicated to detecting wolves consisted of 32
installations and a total of 3,632 trap nights, making up for 33.3 percent of the 2018 monitoring season (Table 4,
Figure 2).
While no wolves were detected in this region, fishers were captured on camera at two locations. Images have
been shared with our project partners involved in recent fisher reintroduction efforts. While the first generation
of reintroduced fishers have a transmitter to aid in monitoring efforts, the detection of fishers will become even
more important to help monitor the reproduction and recovery of this species on the landscape. Mountain lions
were seen at eight survey areas. Nine Level 3 species (black bear, bobcat, coyote, elk, mule deer, striped and
spotted skunks, porcupine, snowshoe hare and smaller mammals) and humans (non-volunteer) (Table 5), were
detected during the season. Blue Lake Ridge and Manastash detected eight Level 3 species and Eagle Creek, Little
Naches, and Taneum detected seven. Three sites, Loup Pass, Jack Creek and Cispus, all had a relatively-low
number of species detections. It is noted that all of these sites were primarily active during the winter months,
and this is not representative of this area over a full calendar year.
