This is a vine and can create some fairly large patches but it is also palatable to cattle and I suspect deer and elk use it as well. I see quite a bit of it locally, but none that has ever grown so thick and large that it seems to be a problem.
After one of my last hikes of last summer into the Patrick’s Knob Roadless area on the top part os USFS trail 205 and the east end of USFS trail 404 I put these photos into a pending file and forgot them. It might be interesting to note that these plants are presently resting under about eight feet of snow.
