State Rank Reason (see State Rank above)
Salix discolor is known from 21 widely scattered locations in Montana from 1911-2010. Plants have been found in city parks that have some native habitat, along roads and a diversion dam, in or adjacent to orchards and homesteads, and in native, un-impaired habitats. Current data is needed on the twelve locations found prior to 1970. This species resembles Salix planifolia and could be overlooked.
