My research focuses on species conservation, habitat management, and effectiveness of restoration in a variety of terrestrial and aquatic ecosystems. I also co-lead the Pacific Northwest Environmental DNA Laboratory.

Pacific Northwest Environmental DNA Laboratory
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 species conservation, wildlife habitat, and restoration. We combine molecular methods, remote sensing, field studies, and statistical modeling. 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.
Science and Products
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...

LTDL and LTET Team (FRESC)
The Land Treatment Digital Library (LTDL) and The Land Treatment Exploration Tool (LTET) are practical resources for land managers planning restoration and rehabilitation projects on public lands.
Project ROAM
USGS is identifying, testing, and verifying rapid methods for rangeland assessment and restoration monitoring. Our methods complement existing monitoring frameworks, providing land management agencies with timely information that can be used to determine if restoration investments are successful, and why. Standardization, validation, repeatability, data management, and training are at the core of...
Proof of concept airborne eDNA testing to detect invasive species in shipping containers
Shipping containers that are transported by water vessels traveling between islands and the mainland or other islands can act as a vector for invasive species that are accidentally transported with the cargo. If the vessel carries a lot of cargo, or cargo has areas for different species to hide, inspections can be difficult, time consuming, and expensive, or in the case of non-agricultural...
Fuel Break Science in the Great Basin
Researchers from the U.S. Geological Survey are developing a strategic framework for assessing and monitoring the impacts of fuel breaks in sagebrush ecosystems of the western U.S. Fuel breaks are increasingly being used to reduce the threat of wildfire, but more information on their efficacy and impacts on wildlife habitat and exotic annual grass invasion is needed.
Systematic Review and Analysis of Seeding and Herbicide Treatment in the Sagebrush Steppe
Seeding and herbicide treatments are a key aspect of the strategy used to break the annual grass-fire cycle in sagebrush steppe. However, past studies report considerable variability in the effectiveness of seeding and herbicide treatments. To generate a more consistent interpretation of post-fire herbicide and seeding effects, we are compiling, reviewing, and synthesizing findings from past...
Using Pollinator Environmental DNA to Assess the Ecological Resilience of America’s Grasslands
Scientists from six USGS science centers are collaborating with USDA, university, and Tribal partners, and Department of the Interior land managers, to assess the status of pollinator communities and the distribution of species of conservation concern using environmental DNA. These methods will be used to improve assessments of habitat quality and pollinator responses to restoration, including...

Dakota Skipper Surveillance, Monitoring, and Assessment
The Dakota Skipper is a small butterfly that once lived throughout the grasslands of the north-central U.S. and south-central Canada but is now listed as threatened under the Endangered Species Act.
Using Artificial Flowers to Survey for Pollinators
Pollinators, such as bees and butterflies, are critical for the success of agriculture and must have suitable habitat to thrive. Planting pollinator-friendly plants under and around solar panels has the potential to benefit pollinators and nearby agriculture while contributing to renewable energy production.
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. The WFTT provides...
READI-Net: Providing Tools for the Early Detection and Management of Aquatic Invasive Species
The USGS has developed the Rapid environmental (e)DNA Assessment and Deployment Initiative & Network (READI-Net) to accelerate the implementation of environmental DNA (eDNA) analysis as a best practice for the early detection of aquatic biological threats. READI-Net provides tools and a strategy to collect and deliver early detection data for natural resource managers and public health protection...

GIS Clipping and Summarization Tool for Points, Lines, Polygons, and Rasters
Geographic Information System (GIS) analyses are an essential part of natural resource management and research. Calculating and summarizing data within intersecting GIS layers is common practice for analysts and researchers. However, the various tools and steps required to complete this process are slow and tedious, requiring many tools iterating over hundreds, or even thousands of...
The Wildfire Trends Tool: A data visualization and analysis tool to meet land management needs and facilitate scientific inquiry
Fighting wildfires and reducing their negative effects on natural resources costs billions of dollars annually in the U.S. We will develop the Wildfire Trends Tool (WTT), a data visualization and analysis tool that will calculate and display wildfire trends and patterns for the western U.S. based on user-defined regions of interest, time periods, and ecosystem types. The WTT will be...
