Type Concept Sentence: This association comprises improved pastures dominated by Cynodon dactylon, with varying degrees of native composition remaining. It is currently only reported from Arizona and California, but also could be found in other western states and ecoregions.
Common (Translated Scientific) Name: Bermuda Grass Western Ruderal Grassland
Colloquial Name: Western Ruderal Bermuda Grass Pasture
Hierarchy Level: Association
Type Concept: This association comprises improved pastures dominated by Cynodon dactylon, with varying degrees of native composition remaining on a wide variety of soils and sites. It is currently only reported from Arizona in Grand Canyon National Park and Tuzigoot National Monument and the Channel Islands of California, but also could be found in other western states and ecoregions. Vegetation is dominated by the introduced grass Cynodon dactylon, with various remnant native species. Although originally planted, Cynodon dactylon maintains itself spontaneously and is considered weedy or "semi-natural" as opposed to cultivated.

Floristics: Vegetation is dominated by the introduced grass Cynodon dactylon, with various remnant native species. Although originally planted, Cynodon dactylon maintains itself spontaneously and is considered weedy or "semi-natural" as opposed to cultivated. Scattered shrubs often occur intermixed or around the periphery of these dense patches of grass. Along riverbanks the tall non-native shrub Tamarix ramosissima is often present.
Dynamics: Although originally planted, this vegetation maintains itself spontaneously and is considered weedy or "semi-natural" as opposed to cultivated.
Environmental Description: This vegetation is weedy or "semi-natural" and is found in pastures and riverbanks, where it maintains itself spontaneously, aided by grazing or mowing.
