Impacts of Soil Climate on Desert Scrubs Distribution in the Mojave Desert
Abstract
Based on the mean annual soil temperature collected with the Pallmann method and data on evaporation, precipitation, and the perennial plant species in 75 monitoring sites in the Mojave Desert from 1982 to 2000, we investigated the interrelationships of soil temperature and aridity on the distribution of several dominant desert scrubs in the Mojave Desert. It showed that the creosote bush-white bursage communities populated in the areas with lower elevation (<1,200 m) and higher soil...
