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.
Biography
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.

Status: Active Wildlife Ecology and Conservation Biology Team (FRESC)
Wildlife respond to changes in their environment, some of which are dramatic and others subtle. To fully understand the factors that drive changes in populations and communities, we need better information on wildlife ecology in natural and human-altered landscapes. We conduct research and provide technical assistance to address applied questions about the ecology and conservation of wildlife...

Status: Active Wildlife Responses to Climate, Land Use, and Invasive Species
Wildlife issues drive many federal and state land management decisions, either because of litigation or mandates to protect habitat and limit extinction risks. We conduct applied research to meet this need, particularly related to the effects of natural (disease, predation) and anthropogenic (habitat loss, invasive species) stressors on wildlife populations and communities. Research on the...

Resource monitoring is critically important for documenting trends and learning from the past (i.e., adaptive management), yet it has been plagued with poor design and execution. We are developing and testing novel approaches to wildlife monitoring, including the use of non-invasive field sampling and molecular markers to determine patterns of species occurrence and population abundance...

Land Treatment Digital Library (LTDL)
The Land Treatment Digital Library (LTDL) was created by the USGS to catalog legacy land treatment information on Bureau of Land Management lands in the western United States. The LTDL can be used by federal managers and scientists for compiling information for data-calls, producing maps, generating reports, and conducting analyses at varying spatial and temporal scales.
Date published: July 24, 2013
Data Entry Module for the Land Treatment Digital Library (LTDL)
This software allows agencies, organizations, and individuals to download an empty, stand-alone Land Treatment Digital Library database to individual or networked computers. Data entered in these databases may be submitted to the USGS for possible inclusion in the online Land Treatment Digital Library (https://ltdl.wr.usgs.gov).
