Quantifying Western U.S. shrublands as a series of fractional components with remote sensing provides a new way to understand these changing ecosystems. The USGS NLCD team in collaboration with the BLM has produced the most comprehensive remote sensing-based quantification of Western U.S. shrublands to date. Nine shrubland ecosystem components, including percent shrub, sagebrush (Artemisia spp.), big sagebrush, herbaceous, annual herbaceous, litter, and bare ground cover, along with sagebrush and shrub heights, were quantified at 30-m resolution by mapping region. Each region required extensive ground measurement for model training and validation, two scales of remote sensing data from commercial high-resolution...

The wildfire probability map was produced to spatially map the potential of wildfire across the sagebrush biome. This dataset may inform wildland fire management decisions including preparedness, suppression, fuels management and post-fire recovery for western sagebrush communities. The extent of the dataset covers all sagebrush communities and grassland with sagebrush components occurring across portions of thirteen western states: Washington, Oregon, California, Idaho, Nevada, Arizona, New Mexico, Utah, Montana, Wyoming, Colorado, North Dakota and South Dakota. Probabiilty values for wildfires => 300 acres were estimated by Short et al. (2016; https://doi.org/10.2737/RDS-2016-0034) and were extracted for the sagebrush...
Management intended to benefit a target species may also affect non-target species that co-occur over space and time. Pinyon jay (Gymnorhinus cyanocephalus) populations experienced long-term declines and rely on habitat that could be lost to conifer removal programs for greater sage-grouse (Centrocercus urophasianus). Using 13 years of point count data (2008-2020) collected across the western United States and a suite of relevant covariates for habitat, we fit a hierarchical model to characterize and predict pinyon jay densities and evaluate population trends. The resulting maps include pinyon jay density at the beginning (PIJA_2008_PredictedDensity.tif) and end (PIJA_2020_PredictedDensity.tif) of our study period,...
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...

We combined approximately 28,000 raven point count surveys with data from more than 900 sage-grouse nests between 2009 and 2019 within the Great Basin, USA. We modeled variation in raven density using a Bayesian hierarchical distance sampling approach with environmental covariates on detection and abundance. Concurrently, we modeled sage-grouse nest survival using a hierarchical frailty model as a function of raven density as well as other environmental covariates that influence risk of failure. Raven density commonly exceeded more than 0.5 ravens per square kilometer and increased at low relative elevations with prevalent anthropogenic development and/or agriculture. Reduced sage-grouse nest survival was strongly...
The Washington Shrubsteppe Restoration and Resiliency Initiative (WSRRI) is a new collaborative effortdedicated to conserving the states shrubsteppe wildlife and habitat in the face of increasing threatsfrom wildfire, climate change and other stressors. As part of a long-term transboundary strategy, we willwork with our partners to further co-develop and integrate TerrAdapt into adaptive management plans,enabling managers to better prioritize where shrubsteppe conservation actions (e.g., protecting corehabitat from invasive annual grasses and fire, restoring sagebrush and mesic habitats post-fire, ormitigating key highway movement barriers) are implemented to maintain ecologically connectednetworks of habitat that...

We will use recently-developed models (see Hanser et al. 2011a) mapping the occurrence or abundance of six sagebrush obligate or near-obligate species of conservation concern (four songbirds, one reptile, and one mammal). We will evaluate how important habitats for each species overlap with similarly developed sage-grouse habitat occurrence models (Hanser et al. 2011b), as well as how sage-grouse priority habitats overlap with biodiversity hotspots for the other sagebrush species. This project will evaluate the degree to which sage-grouse conservation can act as an umbrella for other sagebrush dependent species within the Wyoming Basins ecoregion, the Utah-Wyoming-Rocky Mountain ecoregions in their entirety and...

The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across the western U.S. using Landsat imagery from 1985-2021. The RCMAP product suite consists of nine fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, and tree, in addition to the temporal trends of each component. Several enhancements were made to the RCMAP process relative to prior generations. First, we have trained time-series predictions directly from 331 high-resolution sites collected from 2013-2018 from Assessment, Inventory, and Monitoring (AIM) instead of using the 2016 “base” map as an intermediary....

Conservation of biological communities requires accurate estimates of abundance for multiple species. Recent advances in estimating abundance of multiple species, such as Bayesian multispecies N-mixture models, account for multiple sources of variation, including detection error. However, false-positiveerrors (misidentification or double counts), which are prevalent in multispecies data sets, remain largely unaddressed. The dependent-double observer (DDO) method is an emerging method that both accounts for detection error and is suggested to reduce the occurrence of false positives because it relies on two observers working collaboratively to identify individuals. To date, the DDO method has not been combined with...

EARTH SCIENCE > LAND SURFACE > LANDSCAPE,
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). 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 and...

Candidate Conservation Agreements (CCAs) with Assurances (CCAAs) are valuable conservation tools developed with landowners in conjunction with the FWS to conserve species at risk with the intent of negating an Endangered Species Act listing action. Monitoring is typically the responsibility of the landowner, with varying levels of monitoring of biological parameters (e.g., vegetation characteristics). We propose a pilot project to assess if these conservation tools are actually meeting their intended purpose, provide essential information for any necessary adaptive management and inform future CCAs and CCAAs. Without this information, we will be unable to determine whether FWS conservation efforts are eliciting...

Demographic vital rates differently impact population growth across species, and effective conservation takes advantage of this by targeting management towards the most limiting critical life stages anticipated to respond to management. Current conservation efforts for sagebrush obligate songbirds is inextricably linked to breeding habitats, yet the relative contribution of breeding ecology (e.g. nest success) to overall population declines remains unknown. Combining readily available data with cutting edge analytical tools can fill this missing piece of the conservation portfolio, while also identifying key knowledge gaps. Ultimately this project seeks to empower management with the scientific basis for a demographic...

Climate change over the past century has altered vegetation community composition and species distributions across rangelands in the western United States. The scale and magnitude of climatic influences are unknown. While a number of studies have projected the impacts of climate change using several modeling approaches, none has evaluated impacts to fractional component cover at a 30-m resolution across the full sagebrush (Artemisia spp.) biome. We used fractional component cover data for rangeland functional groups and weather data from the 1985 to 2018 reference period in conjunction with soils and topography data to develop empirical models describing the spatio-temporal variation in component cover. To investigate...
