Bryan C Tarbox, PhD
Bryan Tarbox is a Biologist at the Fort Collins Science Center, whose current work focuses on sage-grouse conservation efforts.
Bryan Tarbox is an interdisciplinary ecologist with experience in conservation planning and adaptive management, prioritization modeling and landscape conservation design, land use/cover change dynamics, avian ecology, wildlife-agriculture dynamics, and human dimensions of conservation. Conservation in working landscapes is a common theme that ties together projects ranging from foraging behavior of avian insectivores in Andean silvopastures to conservation prioritization of Texas grass- and rangelands. Specific methodologies he has employed include: tree-based fuzzy logic modeling systems, The Open Standards for the Practice of Conservation, generalized linear mixed models using both frequentist and Bayesian approaches, and various other statistical, remote sensing and GIS techniques.
He received a BS in rangeland ecology and management from Texas A&M University, completed his PhD at the University of Florida studying conservation biology, and conducted a post-doc at Texas State University focused on landscape conservation design and conservation planning. He is currently working on a variety of projects related to sage-grouse conservation efforts.
Science and Products
Spatiotemporal conditions of vegetation and invasive plant species on mine lands.
To support the Bipartisan Infrastructure Law Ecosystem Restoration program, we are developing 1) a document highlighting remote sensing approaches that can be leveraged for site prioritization, recovery design, and long-term assessments of recovery trends, and 2) data products of vegetation conditions, change, recovery potential, and risk of exotic plant invasion on mine lands. We will incorporate...
Gunnison Sage-grouse Prioritizing Restoration of Sagebrush Ecosystems Tool (PReSET)
In partnership with the United States Fish and Wildlife Service, and other partners, scientists from USGS Fort Collins Science Center are working to create a suite of prioritization scenarios that will inform adaptive management for Gunnison sage-grouse.
Prioritizing restoration and conservation of sagebrush ecosystems in northwestern Colorado
We are working with Colorado Parks and Wildlife (CPW) to pilot an expansion of the Prioritizing Restoration of Sagebrush Ecosystems Tool (PReSET; Duchardt et al. 2021) across northwestern Colorado. We are in the initial phase of a two-phase project where we are leveraging existing data resources to provide customized scenarios that directly guide landscape-scale conservation delivery by CPW. This...
Prioritizing sagebrush protection and restoration within the upper Colorado River Basin
Arid shrublands of western North America face growing threats from disturbances such as wildfire, drought, and invasive species. These threats are increasingly altering the sagebrush ( Artemisia species) biome and degrading habitat for species of conservation concern such as greater sage-grouse ( Centrocercus urophasianus ). Effective management and restoration are needed to slow or reverse these...
Prioritizing restoration and conservation of Wyoming’s sagebrush ecosystems for wildlife and sagebrush connectivity
To support strategic ecosystem management across the imperiled sagebrush steppe in Wyoming, USA, we developed an extension of the Prioritizing Restoration of Sagebrush Ecosystems Tool (PReSET). Our expanded tool leverages emerging spatial data resources to provide a structured but customizable set of scenarios that can guide landscape-scale planning efforts by prioritizing conservation and...
Assessing invasive annual grass treatment efficacy across the sagebrush biome
We are using existing datasets that span broad spatial and temporal extents to model the efficacy of invasive annual grass treatments across the sagebrush biome and the influence of environmental factors on their success. The models we develop will be used to generate maps of predicted treatment efficacy across the biome, which will be integrated into the Land Treatment Exploration Tool for land...
Predicting Recovery of Sagebrush Ecosystems Across the Sage-grouse Range from Remotely Sensed Vegetation Data
USGS researchers are using remote-sensing and other broadscale datasets to study and predict recovery of sagebrush across the sage-grouse range, assessing influence of disturbance, restoration treatments, soil moisture, and other ecological conditions on trends in sagebrush cover. The results will be used to inform conservation prioritization models, economic analyses, climate change projections...
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.
Economic assessment of addressing annual invasive grasses across the sagebrush biome
This interdisciplinary project combines expert judgment on treatment costs with spatially explicit ecological modeling to estimate the financial resources needed to address the threat of invasive annual grass across the entire sagebrush biome. Results of the assessment will provide economic insights that can inform cost-effective resource allocation to efficiently achieve sagebrush conservation...
Prioritizing Restoration of Sagebrush Ecosystems Tool (PReSET): A USGS-facilitated Decision-support Tool for Sagebrush Ecosystem Conservation and Restoration Actions
Sagebrush ecosystems represent one of the most imperiled systems in North America and face continued and widespread degradation due to multiple factors including climate change, invasive species, and increased human development. Effective sagebrush management must consider how to best conserve and restore habitats to stem the decline of species that rely on them, especially given limited...
Invasive Annual Grass (IAG) Spatial Dataset Compilation and Synthesis
USGS is working closely with partners in the Bureau of Land Management (BLM), U.S. Fish and Wildlife Service (USFWS), and the Intermountain West Joint Venture (IMJV) to collect and summarize spatial datasets that describe measurable aspects of invasive annual grasses (e.g., biomass or presence) across the western United Stated and beyond. The products developed through this project provide...
Field of Sagebrush Dreams: Planting and Restoring Functional Sagebrush in Burned Landscapes
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. The products and information developed for this project will help restoration practitioners, biologists, and land managers evaluate the efficacy of sagebrush restoration approaches as well as their ability...
