To revegetate disturbed desert lands, practitioners often reestablish fertile islands as a first step in restoring native plants and associated fauna on disturbed desert sites. This research brief discusses the pros and cons of this approach considering native and non-native species.Read More
For desert shrubland species that have evolved without fire, the introduction of a grass-fire, positive feedback cycle is particularly problematic. This brief discusses work done by researchers who modeled the grass-fire cycle for non-fire-adapted desert shrublands under three sets of climate conditions.Read More
Study results from arid regions in Southern California show how fire trends differ based on unique sets of circumstances. This brief discuses how combinations of direct drivers (like powerline and roadside ignitions), indirect drivers (like invasive grasses, air pollution, and landscape fragmentation terrestrial intactness) and unknown factors cause diversity in fire trends.Read More
Collaboratively with the National Park Service, the authors performed a study along Northshore Road in Lake Mead National Recreation Area (eastern Mojave Desert, Nevada) to develop biocrust restoration strategies. Results and management recommendations for the most effective restoration methods are discussed.Read More
Presented at the Mojave Desert Fire Science and Management Workshop. Barstow, CA 2014.
Conclusions from this presentation include statements about the prehistoric, historic, and current characteristics in the Mojave desert area. For example, high elevation and riparian vegetation types contain many species that evolved with fire, whereas lower elevation vegetation is characterized by species that evolved with very little fire.

This journal article provides a decision framework that integrates fire regime components, plant growth form, and survival attributes to predict how plants will respond to fires and how fires can be prescribed to enhance the likelihood of obtaining desired plant responses.

Presented here is scientific information regarding wildland fire and nonnative invasive plant species, identifies the nonnative invasive species currently of greatest concern in major bioregions of the United States, and describes emerging fire-invasive issues in each bioregion and throughout the nation.

This brief summarizes the current state of knowledge on the use of fire as a tool to manage invasive plants in wildlands. The authors of two publications discuss risks and challenges of conducting prescribed burns, types of systems and circumstances in which burning may be effective for the management of invasive plants, complexities of fire and plant community interactions, impacts of prescribed burning on the broader plant community and the soil, and comprehensive monitoring plans.Read More
