Peter Coates
Dr. Peter Coates is a Wildlife Biologist with the U.S. Geological Survey's Western Ecological Research Center.
He is interested in sound science and management practices aimed at restoring wildlife communities and their habitats. He is committed to progressive, scientifically defensible conservation actions in the face of increasing human population size and individual consumption. Abundance and distribution of wild populations often can be linked to changes in their environments caused by human land use practices, but identifying the ecological mechanisms of declining populations are often challenging. Specifically, Dr. Coates is interested in investigating the links between nesting habitat, predator composition, and incubation behavior and success of birds. Additionally, he is interested in the effects of anthropogenic-resource subsidies on the survival and reproduction of predators and how these changes influence demographics and distribution of prey populations. Dr. Coates seeks to develop a broader understanding of how human-caused landscape changes affect communities and aim to identify restoration practices that preserve natural ecological processes. He is also interested in behavioral traits of grouse that affect population establishment and persistence in the face of environmental challenges.

Estimating spatial variation in greater sage-grouse lek buffers using seasonal space use models
Greater sage-grouse ( Centrocercus urophasianus ) management relies on the identification and protection of core habitat for the species. Core areas are often centered on leks where the potential impacts of anthropogenic development and other disturbances can be evaluated based on buffer distances around active leks. While buffer distances have been quantified for some regions, sage-grouse space...A user-friendly decision support tool for monitoring and managing greater sage-grouse populations

Researchers from the U.S. Geological Survey are reviewing, summarizing, and analyzing what is currently known about changes happening in pinyon-juniper ecosystems in the western U.S. in response to tree removal treatments.

This project will help identify key...Simulating the influence of sagebrush restoration on post-fire sage-grouse population recovery
Increased wildfire-induced loss of sagebrush in North American shrublands are outpacing natural recovery and leading to substantial habitat loss for sagebrush-obligate species like sage-grouse. Transplanting sagebrush ( Artemisia species) is a possible strategy for revegetating burned areas, but little is known about sage-grouse or other wildlife responses to restoration strategies.Using simulation models to project and evaluate post-fire success in restoring sage-grouse habitat over large landscapes
Wildfires are increasingly destroying wildlife habitat in sagebrush ( Artemisia species) ecosystems, and managers need approaches to scope the pace and degree to which post-fire restoration actions can re-create habitat in dynamic landscapes. Sagebrush recovery takes a long time, and it can be difficult to anticipate restoration outcomes over large, diverse landscapes that have experienced decades...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. - Data

Rasters representing Greater Sage-grouse space use, habitat selection, and survival to inform habitat management
We expanded developed methodology to incorporate habitat selection and survival during reproductive life stages and specific seasons with updated greater sage-grouse location and known fate datasets.

The data were collected at Morley Nelson, Birds of Prey National Conservation Area (NCA) where known grazing regimes, including the season of grazing, have been in practice for the last 30 years.

We combined approximately 28,000 raven point count surveys with data from more than 900 sage-grouse nests between 2009 and 2019 within the Great Basin, USA. We modeled variation in raven density using a Bayesian hierarchical distance sampling approach with environmental covariates on detection and abundance. Concurrently, we modeled sage-grouse nest survival using a hierarchical frailty model as aGreater Sage-Grouse Adult and Nest Observations Before and After Wildfire in Northwest Nevada (2008-2019)
Wildfire events are becoming more frequent and severe on a global scale. Rising temperatures, prolonged drought, and the presence of pyrophytic invasive grasses are contributing to the degradation of native vegetation communities. Within the Great Basin region of the Western United States, increasing wildfire frequency is transforming the ecosystem toward a higher degree of homogeneity, one dominaPredictive Maps of Fuel Break Effectiveness by Treatment Type and Underlying Resilience to Disturbance and Resistance to Invasion Across the Western U.S.
Escalated wildfire activity within the western U.S. has widespread societal impacts and long-term consequences for the imperiled sagebrush (Artemisia spp.) biome. Shifts from historical fire regimes and the interplay between frequent disturbance and invasive annual grasses may initiate permanent state transitions as wildfire frequency outpaces sagebrush communities' innate capacity to recover. TheGenotypes and cluster definitions for a range-wide greater sage-grouse dataset collected 2005-2017 (ver 1.1, January 2023)
Monitoring change in genetic diversity in wildlife populations across multiple scales could facilitate prioritization of conservation efforts.

Genetic variation is a well-known indicator of population fitness yet is not typically included in monitoring programs for sensitive species. Additionally, most programs monitor populations at one scale, which can lead to potential mismatches with ecological processes critical to species’ conservation.
