            State Rank Reason (see State Rank above)
            Viburnum edulis is a boreal species that occurs in northwest, north-central, and southwest (in vicinities of Yellowstone National Park and Beartooth Plateau) Montana.  Although documented locations are scattered, the available information suggests that populations are stable with few, if any, threats.  Current data on locations, population sizes, and threats are needed.
