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...Pinyon-Juniper Disturbance Effects on Wildlife
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. Although tree removal can help restore sagebrush ecosystems, these treatments also impact wildlife, wildfire fuels, and invasive plants. This project will help identify key...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.Wildland Fire Trends Tool

USGS scientists are contributing to the development of the Western Association of Fish and Wildlife Agencies Sagebrush Conservation Strategy, a strategy intended to provide guidance so that efforts to conserve the iconic greater sage-grouse can be expanded to the entire sagebrush biome to benefit the people and wildlife that depend on it.Vulnerability of Lower-Elevation Aspen Forests to Altered Fire and Climate Dynamics: Assessing Risks and Developing Actionable Science
Aspen forests are considered keystone ecosystems, meaning that loss of aspen habitat would result in negative impacts to numerous plant and animal species. Aspen also provide important economic and social benefits, including drawing tourists, serving as potential fire breaks, improving local economies, and providing forage for wildlife and livestock. Ecologically-valuable aspen forests are consideCheatgrass and Medusahead
Invasive annual grasses, such as cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae), are one of the most significant stressors to rangeland ecosystems in the western U.S. Their expansion and dominance across this area are the most damaging ecosystem agents on this iconic landscape.Assessing the Effectiveness of Fuel Breaks for Preserving Greater Sage-Grouse in the Great Basin
Fuel breaks have the potential to minimize catastrophic losses of sagebrush habitat and sage-grouse populations by altering fire behavior and facilitating fire suppression. However, they may carry risks to sage-grouse populations—of habitat loss, fragmentation, cheatgrass (Bromus tectorum) invasion, and alteration of sage-grouse movements—that have not been quantified.Role of Fire and Fuels in Ecological Restoration
Fuel loads are important drivers of fire behavior, and fire is an important natural process that can also be used as a tool for ecological restoration purposes. Land managers and fire experts attempt to track and manipulate fuel loads in order to assess fire risk, control fire behavior, and restore ecosystems. Thus, understanding the relationships between fire, vegetation dynamics, and fuel loads...Modeling Disturbance and Ecosystem Change at Landscape Scales
Models can be used to investigate changes in ecosystems and disturbance regimes across large landscapes and over long periods of time, i.e., at spatial and temporal scales that are typically not possible or practical using field-based observational or experimental methods. These spatially explicit models can also be used to investigate complex relationships and interactions among various...Disturbance History in Natural Communities
Disturbance is an important process in most natural communities, shaping ecosystem composition, structure, and function. Studying and quantifying natural disturbance regimes (e.g., fire) often reveal complex relationships with climate, vegetation, and topography, as well as with other disturbance agents (e.g., insects and wind). Characterizing and quantifying past disturbances regimes is also key... - Data

Predictive 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.

The dataset includes several variables sampled across burned and unburned sagebrush communities located in an approximately 30 square kilometer portion of the Columbia Plateau Ecoregion in eastern Washington, USA. The study area is characterized by landforms interspersed at fine-scales, representative of the channeled scabland topography of the region (Baker 2009), including: "mounds," which are dNorthern Nevada aspen (Populus tremuloides) data (2010-2011)

Executive SummaryIncreasing density of pinyon (Pinus spp.) and juniper (Juniperus spp.) woodlands (hereinafter “pinyon-juniper”), as well as expansion of these woodlands into adjacent shrublands and grasslands, has altered ecosystem function and wildlife habitat across large areas of the interior western United States.

Young, Todd E. KatznerImplications of tree expansion in shrubland ecosystems for two generalist avian predators
Shrublands globally have undergone structural changes due to plant invasions, including the expansion of native trees. Removal of native conifer trees, especially juniper (Juniperus spp.), is occurring across the Great Basin of the western U.S. to support declining sagebrush (Artemisia spp.) habitats and associated wildlife species, such as greater sage-grouse (Centrocercus urophasianus).

Fire regimes in sagebrush (Artemisia spp.) ecosystems have been greatly altered across the western United States.

Increased fire frequency in semi-arid ecosystems can alter biochemical soil properties and soil processes that underpin ecosystem structure and functioning, thus threatening native plant communities and the species that rely on them.

Quaking aspen (Populus tremuloides) forests throughout the western United States have experienced significant mortality in recent decades, much of which has been influenced by climate variability, especially drought.

Wildfires in sagebrush (Artemisia spp.) dominated semi-arid ecosystems in the western United States have increased dramatically in frequency and severity in the last few decades. Severe wildfires often lead to the loss of native sagebrush communities and change the biogeochemical conditions which make it difficult for sagebrush to regenerate.
