Common (Translated Scientific) Name: Yellow Willow / Bluejoint Wet Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This is a riparian shrub type likely to occur in the foothills and mountains of central and eastern Montana and the valleys of western Montana, in the lower mountains and the basins of central and western Wyoming, and possibly in southeastern Idaho. In Montana, stands of this type can be found on moist alluvial terraces and around seeps, at elevations between 1116 and 1341 m (3660-4400 feet), which is lower than Salix boothii and Salix geyeriana stands. In Idaho, stands can be expected on gently sloping alluvial terraces below 2130 m (7000 feet), with Salix boothii stands or Salix exigua stands. In Wyoming, Salix lutea stands are found in the foothills and lower mountains. Stands of this association have a tall-shrub layer dominated or codominated by Salix lutea and often containing substantial amounts of Salix bebbiana and Salix exigua. Calamagrostis canadensis contributes as much cover to the undergrowth as does any other native species.

Classification Comments: This association apparently is based on the description by Hansen et al. (1995) of the Salix lutea / Calamagrostis canadensis habitat type from Montana, where the vegetation of "late seral to climax stands" has a tall-shrub layer dominated by Salix lutea and an undergrowth with substantial amounts of Calamagrostis canadensis or Calamagrostis stricta (or both), and less Deschampsia cespitosa. Other references offered as a basis for this association contain less information. All five of Padgett et al.''s (1989) Salix exigua community types contain small amounts of Salix lutea, but only the Salix exigua / Mesic Forbs community type contains Calamagrostis canadensis.
