Great Basin Naturalist Memoirs


Ecotonal distribution of salt-tolerant shrubs was investigated under different kinds of edaphic conditions common to open an closed drainage basins in the northern Mojave Desert. Contributing causal factors involved changes in soil salinity, texture, and moisture stress. Varying degrees of halophytism occured, ranging from plant species that are facultative in their adaptation to salinity to those that require comparatively high salt concentrations in soil for normal growth and development.
