Description: You are a Rangeland Manager for the United States Forest Service, your duties include monitoring several grazing allotments. The last couple of years you have noticed a perplexing situation on the “Best 40 Acres in the West” area. During the last 5 years the ‘West’ has gone from the best to a mess. Over that same five year span you have noticed that a yellow flowering plant has nearly overtaken the “Best 40 Acres in the West.” You have spent a week watching the cows and the wildlife on this allotment. The animals just won’t even try a bite of that yellow flower; in fact they almost appear to be afraid of it. So what is the deal with this plant?
