CEGL000706 Juniperus monosperma / Artemisia tridentata Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: One-seed Juniper / Big Sagebrush Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland community is known to occur in northern New Mexico within Bandelier National Monument and the upper Rio Puerco watershed. It has been found along breakslopes or on mesatops and on northeasterly to easterly aspects of low solar exposure. Stands occur on rubble of steep canyon slopes with rocky soils derived from basalt or andesite colluvium. Within Bandelier National Monument, this community has been found at elevations ranging from 1695 to 1825 m (5460-5740 feet), and it occurs at 2012 m (6600 feet) within the upper Rio Puerco watershed. Within Bandelier National Monument, this association is a short-statured coniferous and open-canopied (10-20% cover) woodland dominated by Juniperus monosperma. Occasionally, mature individuals of Pinus edulis or Pinus ponderosa can be present, although they are typically poorly represented. The understory is characteristically shrubby with Artemisia tridentata well-represented and Ephedra viridis codominant. Fallugia paradoxa, Gutierrezia sarothrae, Opuntia phaeacantha, or Yucca baccata are common associates. Graminoids are common to well-represented with Bouteloua curtipendula and Poa fendleriana the most frequent species. Forbs, while common, are variable in composition and include Eriogonum jamesii and Heterotheca villosa. Within the upper Rio Puerco watershed, this community forms a unique floristic group with Juniperus monosperma and Artemisia tridentata codominant. Additional characteristic species include Pleuraphis jamesii and Sporobolus cryptandrus.
Diagnostic Characteristics: This plant association has Artemisia tridentata in the understory, and a Juniperus monosperma overstory which seldom exceeds 10% canopy cover.

Floristics: Within Bandelier National Monument, this association is a short-statured coniferous and open-canopied (10-20% cover) woodland dominated by Juniperus monosperma.

Forbs, while common, are variable in composition and include Eriogonum jamesii and Heterotheca villosa. Within the upper Rio Puerco watershed, this community forms a unique floristic group with Juniperus monosperma and Artemisia tridentata codominant. Additional characteristic species include Pleuraphis jamesii (= Hilaria jamesii) and Sporobolus cryptandrus. The community can be somewhat degraded with Gutierrezia sarothrae occurring within 30% of sample plots (Francis 1986).
Dynamics: Big sagebrush is easily killed by fire and does not resprout; however, it can reinvade a site if soil-stored or off-site seed is available.
