Bromus tectorum Ruderal Grassland | NatureServe Biotics 2019
click to update datacart
Name: Bromus tectorum Ruderal Grassland Reference: NatureServe Biotics 2019 Description: This herbaceous vegetation type is found throughout much of the intermountain western and southwestern U.S. It occurs most often after disturbance of a natural shrub- or grass-dominated community that results in the replacement of the natural vegetation by non-native, annual grass species of <i>Bromus</i>. <i>Bromus tectorum</i> typically dominates the community with over 80-90% of the total vegetation cover, making it difficult to determine what natural community was formerly present. This vegetation also includes grasslands dominated or codominated by other Eurasian introduced annual <i>Bromus</i> species such as <i>Bromus hordeaceus, Bromus madritensis, Bromus arvensis, Bromus diandrus ssp. rigidus</i>, or <i>Bromus rubens</i>. It is distinct from the annual <i>Bromus</i> communities found along the Pacific coast typical of the Mediterranean or maritime climates. Sites are variable as it occurs on a wide variety of semi-arid landscapes. Elevation ranges from near sea level to 2200 m. In the Great Basin, <i>Bromus tectorum</i> grasslands have invaded large areas of burned-over sagebrush steppe. <i>Bromus tectorum</i> increases the fire frequency of steppe communities, which eventually eliminates sagebrush.  Accession Code: urn:lsid:vegbank.org:commConcept:31919-{044C9D25-6BEA-4B72-A533-A4364F11ACA7} Plot-observations of this Community Concept: 8
