CEGL005599 Juniperus (scopulorum, osteosperma) / Ericameria nana Wooded Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: (Rocky Mountain Juniper, Utah Juniper) / Dwarf Goldenbush Wooded Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This community of the intermountain western U.S. is characterized by an open tree canopy dominated by Juniperus osteosperma, Juniperus scopulorum, or a combination of both. Total tree cover is usually less than 10% and canopy height is usually 2-10 m. The dwarf-shrub Ericameria nana is characteristic of this association. Ericameria nauseosa and Purshia tridentata often occur in the sparse shrub stratum, and other shrub species, such as Holodiscus dumosus, may occasionally be present but not very constant across stands of this type. The moderate herbaceous layer is dominated equally by graminoids such as Poa secunda, Achnatherum hymenoides, Elymus elymoides, and Bromus tectorum, and forbs such as Linanthus pungens, Penstemon deustus, Potentilla glandulosa, and Stephanomeria minor. 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.

Floristics: This community is characterized by an open tree canopy dominated by Juniperus osteosperma, Juniperus scopulorum, or a combination of both. Total tree cover is usually less than 10% and canopy height is usually 2-10 m. The dwarf-shrub Ericameria nana is characteristic of this association. Ericameria nauseosa and Purshia tridentata often occur in the sparse shrub stratum, and other shrub species, such as Holodiscus dumosus, may occasionally be present but not very constant across stands of this type. The moderate herbaceous layer is dominated equally by graminoids such as Poa secunda, Achnatherum hymenoides, Elymus elymoides, and Bromus tectorum, and forbs such as Linanthus pungens (= Leptodactylon pungens), Penstemon deustus, Potentilla glandulosa, and Stephanomeria minor. It may occur in large-patch, small-patch or linear spatial patterns.
Dynamics: This community may show immense variability in annual forb cover. Grazing, precipitation and other factors are likely to influence the presence and abundance of native and introduced annuals.
Environmental Description: 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.
