CEGL005754 Juniperus osteosperma / Eriogonum fasciculatum - Yucca baccata Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Utah Juniper / Eastern Mojave Buckwheat - Banana Yucca Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This upland woodland association occurs in the Mojave Desert in California. Juniperus osteosperma is dominant and characteristic in the sparse to open tree overstory (1-15% cover) with Yucca brevifolia often present at lower cover. The sparse to open shrub layer is variable, ranging from 3 to 23% cover, and is codominated by Eriogonum fasciculatum and/or Yucca baccata often with Cylindropuntia acanthocarpa, Ephedra nevadensis, and Ericameria linearifolia. If present, the herb understory is typically sparse and ranges from 4 to 18% cover. Commonly associated herbs include Achnatherum speciosum, Achnatherum hymenoides, Aristida purpurea, Bouteloua eriopoda, Cryptantha sp., Pleuraphis jamesii, Sphaeralcea ambigua and exotic species Bromus rubens and Erodium cicutarium. Stands are typically found on slopes of rolling hills and mountains, but also occur on channel walls. Sites often occur on mid to high slopes between 1200 and 1800 m elevation with variable aspect. Slopes range from flat to somewhat steep (to 24°). Substrates are variable, such as alluvium, gneiss, granodiorite, limestone, rhyolite, and sandstone that produce a variety of soil textures, but tend to be well-drained, shallow and rocky.

Floristics: This upland woodland is dominated by characteristic species Juniperus osteosperma in the sparse to open tree overstory (1-15% cover) with Yucca brevifolia often present at lower cover (Evens et al. 2014). The sparse to open shrub layer is variable, ranging from 3 to 23% cover, and is codominated by Eriogonum fasciculatum and/or Yucca baccata often with Cylindropuntia acanthocarpa, Ephedra nevadensis, and Ericameria linearifolia (Evens et al. 2014). Other associated shrubs include Echinocereus engelmannii, Gutierrezia sarothrae, and Opuntia polyacantha var. erinacea (Evens et al. 2014). If present, the herb understory is typically sparse and ranges from 4 to 18% cover. Commonly associated herbs include Achnatherum speciosum, Achnatherum hymenoides, Aristida purpurea, Bouteloua eriopoda, Cryptantha sp., Pleuraphis jamesii, Sphaeralcea ambigua, and exotic species Bromus rubens and Erodium cicutarium (Evens et al. 2014)
