HABITAT TYPES AND PLANT COMMUNITIES : 
Mountain willow is a common thicket-forming shrub of streambanks and
moist slopes in the arctic and forested regions of Alaska and the Yukon
[3,14].  Mountain willow can also be found in floodplain thickets on
rivers and grows on recent alluvial deposits characterized by exposed
mineral soil, low moisture content, and absence of permafrost [22].
Mountain willow is best adapted to a cool, moist northern environment
but is also found in warmer, more temperate climates.  In these more
temperate climates, mountain willow occurs at middle to rather high
elevations (6,000 to 10,500 feet [1,800-3,100 m]) in the mountains along
riparian zones [14,15,36].  Published classifications describing
mountain willow as a dominant or codominant in community types are
listed below:

Classification of the riparian vegetation of the montane and subalpine
zones in western Colorado [4].  
Riparian community type classification of Utah and southeastern Idaho [29].
