Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Blue Grama - Sand Dropseed Grassland

Colloquial Name: Blue Grama - Sand Dropseed Shortgrass Prairie

Hierarchy Level:  Association

Type Concept: This herbaceous association is currently only known from El Malpais National Monument in New Mexico, and the following description is based on occurrences there. Additional information will be added as it becomes available. This association occurs between 2085 and 2200 m (6840-7230 feet) elevation on a variety of landforms including valley bottoms, gentle shoulders or footslopes of low hills, and occasionally kipukas and depositional areas in lavaflows. Substrates are mainly derived from alluvium or sometimes from volcanics or sandstone formations. Typically, ground surface cover is dominated by soil, with gravel, rock, litter, and coarse woody debris as minor components. In some areas, pocket gopher mounds and kangaroo rat burrows have disturbed the soil. In this shortgrass prairie grassland, graminoids dominate (generally >25% cover) with Bouteloua gracilis and Sporobolus cryptandrus the most frequent and abundant species. Forbs are scattered and most frequently include Sphaeralcea coccinea and Artemisia carruthii, along with the non-native Salsola tragus. Among trees, Juniperus monosperma and Pinus edulis are scattered about this grassland association, along with the shrubs Ericameria nauseosa and Gutierrezia sarothrae, but seldom exceed 1 or 2% cover.
