Future climates are simulated by general circulation models (GCM) using climate change scenarios (IPCC 2014). To project climate change for the sagebrush biome, we used 11 GCMs and two climate change scenarios from the IPCC Fifth Assessment, representative concentration pathways (RCPs) 4.5 and 8.5 (Moss et al. 2010, Van Vuuren et al. 2011). RCP4.5 scenario represents a future where climate policies limit and achieve stabilization of greenhouse gas concentrations to 4.5 W m-2 by 2100. RCP8.5 scenario might be called a business-as-usual scenario, where high emissions of greenhouse gases continue in the absence of climate change policies. The two selected time frames allow comparison of near-term (2020-2050) and longer-term...

In 'Predicted (1989-2015) and forecasted (2015-2114) rate of change and recovery of sagebrush (Artemisia spp.) following energy development in southwestern Wyoming, USA (ver. 2.0, January 2021)', we provide spatially- and temporally-explicit maps of predictions for the rate of change and time to recovery and percent recovery of sagebrush cover after 100 years (Monroe et al. 2020). The rasters beginning with "sage.rate" depict the predicted annual rate of change in sagebrush cover for each timestamp interval, across the Wyoming Landscape Conservation Initiative area (WLCI) in southwestern Wyoming, USA (1989-2015). The files 'time_to_recov_v2.0.tif' and 'perc_recov_v2.0.tif' are rasters for predicted time to recovery...
Juniper conservation element was measured using an euclidean distance modifier and then low sagebrush was used to extract the distance from juniper.
Juniper conservation element was measured using an euclidean distance modifier and then sagebrush was used to extract the distance from juniper.
These rasters are the result of calculating the difference in Greater Sage-grouse nest survival after a simulated reduction of raven density to 0.1 ravens per square kilometer. The difference in nest survival represents spatial variation in potential to improve nest survival by reducing raven impacts. The extent of each individual raster is the extent of the field site at which sage-grouse nest observations were recorded.
Accurate and consistent estimates of shrubland ecosystem components are crucial to a better understanding of ecosystems condition in arid and semiarid lands. We developed an innovative approach by integrating multiple information to quantify shrubland components as continuous field products within the National Land Cover Database (NLCD). The approach consists of five major parts: field sample collection, high-resolution mapping of shrubland components using WorldView-2 imagery and regression tree models, Landsat 8 radiometric balancing and phenological mosaicking, coarse resolution estimate of shrubland components across a large geographic extent using Landsat 8 phenological mosaics and regression tree models, and...
This fire risk assessment was conducted to understand how resilience and resistance and sage-grouse breeding bird habitat may inform wildland fire management decisions including preparedness, suppression, fuels management and post-fire recovery for western sagebrush communities. The assessment is based on the premise that risk = probability of a threat and the consequences of that threat (negative or positive). Fire risk was determined by the probability of a large wildfire and the consequences of fire on greater sage-grouse breeding habitat. These consequences were modified by the capacity of sage-grouse habitat to be resilient and thus recover from fire processes, and be resistant to invasive annual grasses. The...

We evaluated sagebrush on 24 post-fire seeding sites encompassing >50,000 acres on the Snake River Plain in the Northern Great Basin, specifically in southwest Idaho. Sites were initially identified using the Land Treatment Digital Library (LTDL; http://greatbasin.wr.usgs.gov/ltdl/; and Inciweb fire information (http://inciweb.nwcg.gov/) websites to identify seeding projects located in predominantly Wyoming big sagebrush sites (2,500 to 4,000 feet ASL; 2 sites also had A.t. vaseyana, 2 other sites had only A.t. vaseyana) that (1) had burned and were seeded within the year following fire, from 1987-2010, (2) but had not burned since, and (3) had information on seed sources. Standard USDA species abbreviations are...

These datasets provide early estimates of 2023 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a weekly basis from May to early July. The EAG estimates are developed typically within 7-13 days of the latest satellite observation used for that version. Each weekly release contains four fractional cover maps along with their corresponding confidence maps for: 1) a group of 16 species of EAGs, 2) cheatgrass (Bromus tectorum); 3) medusahead (Taeniatherum caput-medusae); and 4) Sandberg bluegrass (Poa secunda). These datasets were generated leveraging field observations from Bureau of Land Management (BLM) Assessment, Inventory, and Monitoring (AIM) data plots; Harmonized...

This dataset includes modeled outputs for structural connectivity and trends in connectivity patterns in the sagebrush biome of the United States at 270-meter resolution. Connectivity was calculated using an omnidirectional circuit-based algorithm, with sources, targets, and conductance based on sagebrush fractional component from the RCMAP sagebrush products for 1985, 1990, 1995, 2000, 2005, 2010, 2015, and 2020. Cumulative current density was used to represent connectivity and normalized cumulative current density represented relative flow patterns. We also calculated rasters to represent linear trend in connectivity class, relative flow, and the consistency of connectivity classes.
This funding will be used to hire 1 GS 12 Sagebrush Coordinator, who will focus on conservation delivery through completion and implementation of CCAA with NDOW, and other public/private landowners.

PI’s and student have compiled and coded an extensive literature review of social science in the sagebrush biome. They have also developed, piloted and refined a social science needs assessment survey which has been transmitted to over 600 stakeholders in the sagebrush system (identified through Patrick Bixler’s work). They are now planning to conduct focus sessions in 4 states they are focusing on (WY, CO, ID, and OR), with the intent to focus a significant portion of the focus group discussion on the ways in which social science can inform decision making for sagebrush management and conservation.

This project expands upon a large, multi-agency collaborative study (Univ. of Idaho, Idaho Game and Fish, BLM, Great Basin LCC & two grazing Associations) evaluating the impacts of alternative grazing systems on sage-grouse over a 10-year period using a staggered entry BACI design. This project will evaluate the effects of grazing management prescriptions (intended to be compatible with greater sage-grouse) on other sagebrush-obligate or associated avian species. The results will contribute to an adaptive management process by: 1) assessing current state of populations of sagebrush-dependent birds as well as limiting factors, 2) compilation of models describing population-habitat relationships that can lead to species-habitat...

Rest-rotation grazing, defined as lack of livestock grazing in a pasture for 15-18 months, is suggested to improve the quality of sagebrush, shrubland, and grassland habitat for a wide range of species. However, little work has been done to evaluate impacts of rest-rotation grazing on migratory avian species which serve as indicators of sagebrush ecosystem integrity. Evaluating the impacts of rest-rotation grazing using indicator species can provide valuable insight into how rest-rotation grazing may affect multiple species in the ecosystem.Our research is focused on how different grazing systems, rest-rotation and traditional, change songbird community structure (e.g., species abundance and richness). Traditional...

Emerging applications of ecosystem resilience and resistance concepts in sagebrush ecosystems allow managers to better predict and mitigate impacts of wildfire and invasive annual grasses. Soil temperature and moisture strongly influence the kind and amount of vegetation, and consequently, are closely tied to sagebrush ecosystem resilience and resistance (Chambers et al. 2014, 2016). Soil taxonomic temperature and moisture regimes can be used as indicators of resilience and resistance at landscape scales to depict environmental gradients in sagebrush ecosystems that range from cold/cool-moist sites to warm-dry sites. We aggregated soil survey spatial and tabular data to facilitate broad-scale analyses of resilience...

Invasive annual grasses and wildfires have created a rangeland restoration emergency in the western U.S. This project seeks to demonstrate the efficacy of an integrated and multi-faceted approach to restoration using a case study in a ranch setting that represents the typical restoration needs and challenges common across rangelands of the Intermountain West. These include invasive annual grass and other weed species, wildfire, conifer encroachment, and loss of native bunchgrass and sagebrush cover. This variety of ecological stressors and restoration needs typical of many sites necessitates implementation of a diversity of restoration tools such as annual grass control, conifer cutting, prescribed fire, herbicides,...
