CEGL001653 Panicum bulbosum - Alopecurus aequalis Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bulb Panicgrass - Short-awn Foxtail Grassland
Colloquial Name: Bulb Panicgrass - Short-awn Foxtail Grassland
Hierarchy Level: Association
Type Concept: This association occurs in the lower foothills zone of an isolated desert mountain range in New Mexico. It is found along narrow channels of intermittent streams in draws or small canyons of the Animas Mountains foothills, at about 1770 m elevation. Soils are derived from silty alluvium and are gravelly loams, with a component of surface rocks. This is a lush, herbaceous wetland association, dominated by the mid-height perennial bunchgrasses Panicum bulbosum and Alopecurus aequalis. Together these species average 60% cover. Scattered seedling or saplings of the broad-leaved deciduous tree, Fraxinus velutina, may occur. Other herbaceous species are primarily graminoids, with few forbs, and contributing little cover (<5%). No other information is available. Although only one example of this association has been documented, it is probably a remnant example of a type once much more extensive. The documented example is in very good condition, with little evidence of grazing impacts.

Environmental Description: This association occurs in the lower foothills zone of an isolated desert mountain range. Most of the annual precipitation occurs during the summer months as the result of convectional thunderstorms and during winter as occasional rains. Late spring and early summer are typically dry. Summers are hot, and winters can have periods of cold weather and occasional snows.
