Riparian Plants: Sandbar Willow - Salix exigua

Return to riparian plant list or the Ecological Tolerances of Riparian Plants page.

Sandbar willow can be a dominant species in willow scrub communities and is common in mixed riparian forests. Sandbar willow is moderately shade tolerant. These willows require root access to the water table within 2 meters, which typically places them on low elevation floodplains. With this proximity to the channel, they can contend with physical battering and long duration floods. They have multiple, small diameter stems (most <10 inches) that bend or break under high flows. They can re-sprout easily from branches that break off, which makes sandbar willows easy to plant in restoration using cuttings. They are adapted to coarse and medium grain soils, and require bare gravel or sand substrate that is moist to germinate and develop.

Sandbar willows grow as erect, small shrubs in willow scrub communities and as small trees in mixed riparian forests. They can reach up to 8 meters tall. They spread quickly through root sprouting. Sandbar willow frequently forms a wide patch of several small diameter stems. Sandbar willow thickets and sandbar willows in mixed riparian forests create ideal nesting substrate for many songbirds. The leaves of sandbar willows attract multiple insects, and both leaves and branches make good foraging material.
