HABITAT TYPES AND PLANT COMMUNITIES : 
Sandbar willow usually occurs in early seral communities.  These are
typically riparian and occur as narrow bands immediately adjacent to the
stream or river edge.  Throughout the Rocky Mountain States, it commonly
occurs as a dense shrub layer adjacent to bottomlands of cottonwood
(Populus spp.) and birch (Betula spp.) [23,31,60].  Published
classifications listing sandbar willow as an indicator or dominant in
community types (cts), habitat types (hts), plant associations (pas),
riparian site types (rst), or riparian zone associations (rzas) are
