We used a combination of reports of occurrence, harvest locations, and hunter and trapper questionnaires to determine the distribution of mountain lions in North Dakota. We examined abundance of mountain lions in relation to previous years (i.e. trend information) via these same methods, as well as previous habitat analysis. Additionally, we necropsied mountain lion carcasses to collect demographic, dietary, and genetic information. Necropsies indicate a small, but healthy population of mountain lions occurring in western North Dakota.
