Explains biological soil crusts, organism-produced soil formations commonly found in semiarid and arid environments, with special reference to their biological composition, physical characteristics, and ecological significance.
Fact sheet on the need to protect biological soil crusts in the desert. These crusts are most of the soil surface in deserts not covered by green plants and are inhabited by cyanobacterium (blue-green algae) and other organisms useful to the ecosystem.
Buffelgrass (Pennisetum ciliare) poses a problem in the deserts of the United States, growing in dense stands and introducing a wildfire risk in an ecosystem not adapted to fire. This report explains what we are doing to help mitigate its effects.
Study of wildland fire history and fire ecology such as plants in the Sierra Nevada forests, California shrublands, the Mojave, and Sonoran deserts to develop management techniques that will reduce hazards.
Overview of studies of fragile and active landscape of the American Southwest deserts, including projects on geologic mapping, surface processes, remote sensing research, ecological processes, and earthquake hazard applications.
Research results (publications, photographs, maps) on ecological processes within the Mojave Desert Ecosystem to provide land managers with scientific understanding and tools needed to conserve and restore threatened desert landscapes.
