Impacts of Exotic Annual Grass Invasion, Wildfire, and Restoration on Carbon Storage in the Sagebrush Steppe

USGS is investigating the impact of the annual grass-fire cycle-- and restoration land treatments aimed at slowing that cycle-- on carbon storage in dryland soils.

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...

Climate-Smart Vegetation Treatments - Using 15 Years of SageSTEP Data to Inform Management of Resilient Ecosystems

Land managers require clear, forward-looking information about where and how vegetation treatments may make the greatest difference for drought resilience in sagebrush and woodland ecosystems. We are using soil moisture and vegetation data from SageSTEP-- a long-term ecological study on fuel treatments in the Great Basin-- to analyze soil moisture dynamics and vegetation responses after common...

Understanding the Sagebrush Steppe’s Threshold for Transitions Through Resistance and Resilience Models

We are investigating ecosystem transitions and thresholds in the sagebrush steppe, studying factors influencing the shift from native to invaded plant communities after disturbances like fire. Our research tests region-wide resistance and resilience models, focusing on real-world recovery patterns, pre-fire conditions, plant succession, and land management treatments.

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...

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.

The Effect of Pre-Emergent Herbicides on Soil in The Sagebrush Steppe

We are studying how herbicides sprayed onto soil to prevent the establishment of exotic annual grasses such as cheatgrass may impact the health, growth resources and microbiota of soils in sagebrush-steppe, where herbicide use is an important and common tool. Our findings will help make herbicide applications more successful.

Longevity of Herbicides Targeting Exotic Annual Grasses in Sagebrush-Steppe Soils

Pre-emergent herbicides applied to soil are a primary tool for reducing exotic annual grasses, such as cheatgrass, in sagebrush steppe rangelands. Effective herbicide application can allow existing perennials to grow and spread to outcompete cheatgrass, preventing reinvasion, but most perennials are slow-growing and require more years of relief from annual-grass competition than standard...

Grazing Effects on the Annual Grass Fire-Cycle after Post Fire Management

In order to break the annual grass fire-cycle in the sagebrush steppe, land managers use pre-emergent herbicides to reduce annual grass populations and seeding to increase fire-tolerant perennials. These tools must be applied to the same soils in ways that are not counterproductive, and their application must therefore be staggered in time, which we refer to as layering. Livestock grazing can also...

Quantifying Carbon Storage and Greenhouse Gas Emissions in Sagebrush Rangelands

Management partners have identified a major need to understand the short and long-term consequences of altered wildfire patterns, vegetation change, climate, and management actions for the carbon cycle. This project aims to quantify carbon storage and greenhouse gas emissions in sagebrush rangelands. Researchers will link findings to the Sagebrush Conservation Design Framework and provide...

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 effects...
