Sand Dune Willow

About Sand Dune Willow in Alberta

In this Alberta-focused treatment, sand dune willow is best anchored to Salix brachycarpa, a native low shrub of mountain, northern, wet-cold, and specialized substrate habitats rather than a common prairie dune or urban willow. In Alberta it is associated with open forests, sedge fens, seepage on limestone, scree slopes, gravel floodplains, and other cold or high-elevation settings where compact stature and hairy glaucous foliage fit a specialized native shrub role. For Ancient Roots Alberta, it matters through intact mountain and northern wetland systems, calcareous seepage habitats, and uncommon native willow assemblages rather than through large ornamental or settlement plantings.

Identification: Leaves are narrowly oblong to elliptic, narrowly oblanceolate, or obovate, with entire margins. The lower surface is glaucous and white-villous or long-silky, while the upper surface can be somewhat shiny with white hairs that may become reduced with age. Compared with narrow alluvial willows, the leaves feel short, compact, and specialized rather than long and streambar-like.

Alberta range and habitat: Salix brachycarpa is native in Alberta, but it is not a broad lowland willow of ordinary settled landscapes. Alberta occurrence is real yet ecologically selective, centered on mountain, northern, seepage, calcareous, and other cold open habitats.
