The climate-niche distribution--or the areas with suitable climate for survival--were mapped 130 reptile species in the recent time period and predicted for the late-century time period under the RCP 8.5 climate scenario. The RCP 8.5 scenario assumes carbon emissions continue at their current levels.

My research focuses on evaluating effects of disturbances, such as wildfire and invasive species, and effectiveness of restoration in a variety of terrestrial and aquatic ecosystems.
I lead a team of scientists that develop tools and models to improve understanding of ecological systems and solve challenging problems in natural resource management. We primarily address questions related to wildlife habitat, species conservation, and restoration. Our research team also develops data management and decision support systems to facilitate adaptive management, especially in western rangelands. We primarily work on issues affecting the Intermountain West and Great Basin regions of the U.S.

An examination of long-term data for lands managed by the Bureau of Land Management finds that land treatments in the southwestern United States are increasingly large, expensive and related to fire and invasive species control.

Wildland Fire Trends Tool
The Wildland Fire Trends Tool (WFTT) is a data visualization and analysis tool that calculates and displays wildfire trends and patterns for the western U.S. based on user-defined regions of interest, time periods, and ecosystem types. Users can use the tool to easily generate a variety of maps, graphs, and tabular data products that are informative for all levels of expertise.
Land Treatment Exploration Tool
The Land Treatment Exploration Tool is designed for resource managers to use when planning land treatments. The tool provides useful summaries of environmental characteristics of planned treatment areas and facilitates adaptive management practices by comparing those characteristics to other similar treatments within a specified distance or area of interest. Provisional Software.
