Transient Nenets campsite near BGF (see Fig. S1). Under long-term grazing, trampling, and feces deposition, plant functional types shift from woody plants to clonal rhizomatous graminoids (e.g., Alopecurus, Eriophorum, Carex, Poa). Such lush habitats constitute nutrient-rich and easily digestible forage (37, 59), which foster more intensive localized feeding. Photo by B.C.F.
