HABITAT TYPES AND PLANT COMMUNITIES : 
Barren-ground willow codominates in several willow and mixed shrub
floodplain communities in Alaska and northern Canada [2].  In
northwestern Colorado, it is a codominant along rivers and streams along
with diamondleaf willow (Salix planifolia), marsh marigold (Caltha
leptosepala), and water sedge (Carex aquatilis) [3].  Other riparian
community associates include Alaska willow (S. alaxensis), littletree
willow (S. arbusculoides), grayleaf willow (S. glauca), and alders
(Alnus spp.) [4,18].
