Rocky Mountain iris (Iris missouriensis) increased in dominance with increasing livestock grazing. These wet meadows occasionally had low to moderate cover of shrubby cinquefoil (Dasiphora fruticosa). Emergent marsh was the second most sampled wetland system (Figure 17). Marshes had similar species composition to wet meadows; however, these wetlands typically had lower species diversity, tending to be dominated by graminoids, particularly sedges. Marshes also had a higher proportion of wetland obligates such as C. utriculata and common cattail (Typha latifolia). Riparian shrubland sites were the third most sampled system (Figure 18). These wetlands were dominated by various willow (Salix) species, particularly Booth's willow (S. boothii), Geyer willow (S. geyeriana), and Drummond's willow (S. drummondiana). Redosier dogwood (Cornus sericea), gooseberry (Ribes spp.), and Wood's rose (Rosa woodsii) were also commonly occurring woody species. ^T| ^^2 ^^gl_ k;2 . IK SE9 3 Jk U « to' Figure 17.
