Estimating locally relevant scales of effect for population trends of a species of conservation concern

Wildlife movement and distribution can be influenced by local conditions like topography and landscape features, and the distances within which species respond to their landscape – scales of effect – can vary over space and time. We are estimating scales of effect for wildlife population trends to help land managers determine the distance within which wildlife will respond to landscape change.

USGS Science Syntheses for Public Lands Management

Scientific information is fundamental to understanding how proposed actions on public lands may impact the environment. Development of new science is occurring at rates that can make it challenging for biologists, resource managers, decision makers, private landowners, and other stakeholders to ensure they are using up-to-date, high-quality science information to inform their decisions. Further...

Economics of Wildland Fire

In recent decades, wildfires have increased in size and intensity, and the fire season has lengthened. This and other factors have increased wildfire suppression costs and risks to human health and safety. Economists in the Social and Economic Analysis Branch (SEA) at FORT investigate numerous aspects of wildland fire, its impacts, and how to mitigate the risk wildfire poses to people, resources...

The Wildfire Research (WiRē) Team

Wildfires cost billions of dollars to suppress annually, yet they still devastate lives, communities, and ecosystems. While wildfire is a natural phenomenon, learning to live with wildfire is a social issue – so we need a social solution.

Supporting energy and mineral development through successful reclamation

Federal lands of the US contain important reserves of oil, gas and other resources important for Unleashing American Energy (SO 3418). After development of these resources is complete, successfully reclaiming disturbed lands is a necessary step towards restoring wildlife habitat, forage production, and maintaining natural resources for future use. To improve reclamation outcomes on these lands and...

Fostering greater use of habitat models for managing rare and invasive plants on public lands

Habitat models can provide critical information on the current and potential distribution of plant species, as well as help target and support conservation efforts. Despite their potential utility in public land management, model use may be constrained by a variety of factors including staff access to and trust in models. In this project, we seek to bring together model users and model developers...

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...

Creating range-wide predictive maps of Greater Sage-Grouse seasonal habitats

Through a collaborative effort with multiple state and federal agencies, university researchers, and individual stakeholders, we are producing a set of predictive seasonal habitat maps for greater sage-grouse ( Centrocercus urophasianus) spanning the entirety of the species’ U.S. distribution. This is the largest habitat modeling effort of its kind for the species and uses a large, compiled...

Reconstructing Flow History From Riparian Tree Rings

FORT aquatic scientists analyze rings of riparian trees relating tree growth and establishment to historical flow. They then use the tree rings to reconstruct the flow in past centuries. Flow reconstructions discover the frequency and magnitude of past droughts and floods—information that is essential for management of rivers and water supplies. They have pioneered the use of cottonwood, a...
