Name: Pinus monophylla Wooded Tall Herbaceous Alliance
Reference: Western Ecology Working Group of...
Description: These communities have been described from the Basin and Range Province of southern Idaho at between 1800 and 2200 m in elevation. The climate is semi-arid, with approximately 25-30 cm of precipitation annually. Soils are derived from gneiss, schist, quartzite, and amphibolite, and are well-drained. Leymus cinereus is known to typically occur on gravelly soils, but especially on those derived from alluvium along washes and gullies. From this it can be inferred that this alliance may occupy topographic depressions and narrow canyons where alluvial deposition has occurred. It may also occupy small alluvial fans at the base of erosional features such as rock ridges and tors. These communities are characterized by an open canopy (typically less than 25% cover) of Pinus monophylla, usually in association with Juniperus osteosperma. There is apparently no shrub layer. The herbaceous layer is dominated by Leymus cinereus, a tall perennial bunchgrass. A number of Great Basin species probably occur in these stands, however, no other information on species composition is available.
