News from the Wolverine Tracking Project and more
This week we've seen some old favorites and made some new friends.
Camera teams went to Government Camp East, Little Zig Zag, and Yellowjacket East. Our tracking trip explored near Salmon River Meadows.
Tracking Trip Updates
The tracking trip to Salmon River Meadows found some incredible examples of snowshoe hare tracks. Check out this perfect bound!
We are still EXCITED about finding snowshoe hare tracks. Are you? Although they are undeniably some of the most common tracks to find in the snow, NOT finding them would be devastating. Snowshoe hares are a keystone species, and without them our forests would be drastically different. Whenever you see a coyote, fox, marten, or other carnivore track, thank a snowshoe hare.
While the keystone-species relationship between snowshoe hares and Canada Lynx has been discussed at length, their relationship to other species is equally interesting. When hare populations rise, their effect on willow and alder begins to take a toll. Incredibly, new willow and alder shoots will begin to produce a distasteful and slightly toxic substance to discourage the hares from decimating the young trees. As a result, hare populations begin to decline. Within a few seasons, willow and alder shoots lose the toxic substance and hare populations begin to rise again.
Wildlife Camera Findings
It's March which means it's that time of year for foxes! Breeding season is finishing up around now and come April, anywhere from 2 to 10 pups will come into the world in a cozy den, loyally tended to by both of their parents.
Every family has their share of drama, and Family Canidae is no exception. There is some history of hostility between the different members of the canine family, whether it be wolves and coyotes or coyotes and foxes.
Wolves and foxes seem able to tolerate one another, as their substantial size difference probably does not threaten competition between them. Now that wolves, coyotes, and foxes are all sharing Mount Hood National Forest again, we imagine the first fox-wolf meeting went something like this!
Marten are going to be expecting their kits in the next month or two as well! Marten, like the rest of the family mustelidae, exhibit delayed implantation; if you can believe it, their breeding season was way back in July or August!
This is not the first time this dusky grouse has appeared on camera. For a few months, she has made regular appearances perusing the snow around the camera looking for her favorite wintertime snack: pine and fir needles. Interestingly, this might be one of the last times we see her until next year, check out this article to find out why!
If you do get a chance to see this grouse before she heads back down in the spring, be ready because she is FEARLESS!
She was NOT fed or approached. Incredibly, she approached while the team was talking and assembling the camera, sticking around for the entire time! She would snack on pine needles, watch the camera team, approach, retreat to a nearby branch, and then do it all over again!
