CEGL005589 Cercocarpus ledifolius - Purshia tridentata / Poa secunda Scrub
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Curl-leaf Mountain-mahogany - Antelope Bitterbrush / Sandberg Bluegrass Scrub
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: The vegetation of this association is characterized by low to moderate shrub cover dominated by Cercocarpus ledifolius. Purshia tridentata is also important in the shrub stratum of this community, but it often occurs at low cover values. Other shrub species may also be present on occasion. Juniperus osteosperma may occur sporadically, but not with enough regularity or abundance to form a tree canopy. The sparse herbaceous layer has few graminoids, but Poa secunda is always present and Elymus elymoides commonly occurs. The introduced annual grass Bromus tectorum also occurs with some regularity. Forb cover is very low but Lactuca serriola, Phacelia hastata, and Stephanomeria minor are all commonly found in the understory of this plant community. This association, like all associations in ~Inter-Mountain Basins Volcanic Rock and Cinder Land (CES304.791)$$, is limited to barren and sparsely vegetated volcanic substrates of basalt and basaltic andesite origin, including tuffs, cinder cones, spatter cones, pressure plateaus, or cinder fields. It may occur in large-patch, small-patch or linear spatial patterns.

Classification Comments: This plant community description is based on data from Craters of the Moon (Bell et al. 2009) and on related plant communities that have been previously described. The description provided herein may vary slightly from similar plant communities found elsewhere due to the local scale at which data were collected. Additional global information will be added as it becomes available.
This association is uncommon at Craters of the Moon National Monument and Preserve. Due to the limited spatial extent of occurrence and associated low sample size, the classification of this plant community is considered provisional. Consequently, the characteristic species list for this plant community at Craters of the Moon is also limited.
