Name: Chorizanthe rigida - Geraea canescens Desert Pavement Alliance
Reference: NatureServe Biotics 2019
Description: This alliance consists of sparsely vegetated rock outcrops where the most abundant species include <i>Chorizanthe rigida, Eriogonum fasciculatum, Eriogonum inflatum, Geraea canescens</i>, and/or <i>Larrea tridentata</i>. This alliance is composed of unvegetated to very sparsely vegetated (&lt;2% plant cover) landscapes, typically flat basins where extreme temperature and wind develop ground surfaces of fine to medium gravel coated with "desert varnish." This alliance occurs throughout much of the warm deserts of North America. It may surround playas in valley bottoms or near washes and, less commonly, on dissected, eroding alluvial fans. Very low cover of desert scrub species is usually present. However, ephemeral herbaceous species may have high cover in response to seasonal precipitation.
