DISTRIBUTION AND OCCURRENCE

SPECIES: Salix geyeriana | Geyer Willow
GENERAL DISTRIBUTION : Geyer willow occurs from southern British Columbia southward in the mountains to central California, central Arizona, and southern Colorado. It is widespread in the Cascades, Sierra Nevada, and northern and central Rocky Mountains, and is found in scattered mountain ranges in southern Idaho, eastern Oregon, Nevada, northern Utah, southern Colorado, and Arizona [33,34].

These communities have an "open and clumpy appearance" or an "open, corridor-like structure". Large patches of Geyer willow form the overstory, with lesser amounts of shrubby willow species intermixed in the openings. Willow associates include Booth willow (Salix boothii), yellow willow (S. lutea), Bebb willow (S. bebbiana), planeleaf willow (S. planifolia ssp. planifolia), Drummond willow (S. drummondiana), and Lemmon willow [5,30,54]. The undergrowth is often dense, and dominated by sedges (Carex spp.), bluegrasses (Poa spp.), tufted hairgrass (Deschampsia caespitosa), bluejoint reedgrass (Calamagrostis canadensis), or mesic forbs [24,30,44,54].
