Fifteen fires from the Chronosequence dataset (see Knutson et al. 2014) were visited in 2012 and 2013 and surveyed for cover of lichens and mosses. Fires were selected to cover the range of average precipitation for each of three water years following fire, fire severity, time since fire, season of ignition, total acres burned and grazing intensity. Cattle grazing was characterized by distance from water sources for cattle, cow dung density counts and Animal Unit Months from the Rangeland Administration System of the Bureau of Land Management. Fire was characterized by whether or not a site burned, time since fire, the area burned, and an estimated amount of shrub cover consumed by the fire as compared to seemingly...

Five principal components are used to represent the climate variation in an original set of 12 composite climate variables reflecting complex precipitation and temperature gradients. The dataset provides coverage for future climate (defined as the 2040-2070 normal period) under the RCP8.5 emission scenarios. Climate variables were chosen based on their known influence on local adaptation in plants, and include: mean annual temperature, summer maximum temperature, winter minimum temperature, annual temperature range, temperature seasonality (coefficient of variation in monthly average temperatures), mean annual precipitation, winter precipitation, summer precipitation, proportion of summer precipitation, precipitation...

Monthly Standardize Precipitation Evapotranspiration Index (SPEI), Daily soil-water potential (MPa) and soil temperature (degree C) data for plots from SageSuccess. The SageSuccess Project is a joint effort between USGS, BLM, and FWS to understand how to establish big sagebrush and ultimately restore functioning sagebrush ecosystems. Improving the success of land management treatments to restore sagebrush-steppe is important for reducing the long-term impacts of rangeland fire on sage-grouse and over 350 other wildlife species that use these habitats.

The distribution and abundance of cheatgrass, an invasive annual grass native to Eurasia, has increased substantially across the Intermountain West, including the Great Basin. Cheatgrass is highly flammable, and as it has expanded, the extent and frequency of fire in the Great Basin has increased by as much as 200%. These changes in fire regimes are associated with loss of the native sagebrush, grasses, and herbaceous flowering plants that provide habitat for many native animals, including Greater Sage-Grouse. Changes in vegetation and fire management have been suggested with the intent of conserving Greater Sage-Grouse. However, the potential responses of other sensitive-status birds to these changes in management...

FY2014One of the primary challenges facing public land managers in the Great Basin is identifying adaptation strategies to increase resiliency to climate change in an area that is already struggling with profound environmental challenges. Recent efforts to understand how the Great Basin weathered past droughts and climate variability may offer insight into approaches that could work in future decades. One approach to gather this information is to understand Traditional Ecological Knowledge (TEK). Gathering this information is challenging and requires an acknowledgment that much of this information is highly sensitive and proprietary. Translating this information into actionable management plans is even more challenging.This...

The dataset supports a larger study that examined the impacts of three tackifiers (guar, psyllium, and polyacrylamide) on growth of two dryland mosses (Bryum argenteum and Syntrichia ruralis). Moss fragments were grown in petri dishes and subjected to individual tackifiers in one of three possible concentrations (0.5x, 1x, or 2x) of the respective manufacturer's recommended application rate. Distilled water was used as a control treatment, giving a total of ten treatments (nine tackifier-concentration combinations and a water control). Bryum fragments were watered four times daily for six weeks and Syntrichia fragments were watered twice daily for five weeks, after which the experiments were concluded. Shoot length,...

This dataset includes the magnetotelluric (MT) sounding data collected in 2003 along a north-south profile west of Tooele, Utah. It is important to know whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province. It is also important to know the location and orientation of the Archean/Proterozoic suture zone between these provinces as well as major basement structures within these terranes because they may influence subsequent patterns of sedimentation, deformation, magmatism, and hydrothermal activity. This study was funded by the U.S. Geological...

FY2017There is an increasing concern and need for the conservation of springsnails and other endemic mollusks and for conservation of the unique spring and springbrook habitats on which they depend (Hershler et al 2014; Abele 2011). Nationwide, several of these species have been listed as endangered or threatened under provisions of the ESA; others are candidates for federal listing or are undergoing review by USFWS for possible future listing actions. These species can be particularly susceptible to localized threats and specific knowledge necessary for effective site-based conservation is often limited or lacking.Springsnail are particularly susceptible to extinction because the entire population of any single...

The study's goal was to downscale 2013 250-m expedited Moderate Resolution Imaging Spectroradiometer (eMODIS) Normalized Difference Vegetation Index (NDVI) to 30 m (Gu, Y. and Wylie, B.K., 2015, Developing a 30-m grassland productivity estimation map for central Nebraska using 250-m MODIS and 30-m Landsat-8 observations, Remote Sensing of Environment, v. 171, p. 291-298)using 2013 Landsat 8 data. The eMODIS NDVI was downscaled for four periods: mid spring, early summer, late summer and mid fall. The objective was to capture phenologies during periods that correspond to 1) annual grass growth, 2) annual grass senescence, 3) the optimal NDVI profile separation between sagebrush and other shrubs in the region, and...

FY2016This project will develop a strategic approach for conservation of wet meadows and riparian ecosystems and the species they support that focuses on threats caused by natural and anthropogenic disturbance. It uses information on (1) the factors that affect wet meadow and riparian ecosystem resilience to both natural and human-caused disturbances at the scale of the watershed and meadow or riparian ecosystem, and (2) the distributions and population abundances of at risk species to determine focal areas for management. Maps of the relative resilience of watersheds and wet meadows are overlaid with data on at risk species and the predominant threats to facilitate this process. Decision matrices are developed...

FY2014Although the future of sage grouse depends on the future of sagebrush, we have limited ability to anticipate impacts of climate change on sagebrush populations. Current efforts to forecast sagebrush habitat typically rely on species distribution models (SDMs), which suffer from a variety of well-known weaknesses. However, by integrating SDMs with complementary research approaches, such as historical data analysis and mechanistic models, we can provide increased confidence in projections of habitat change. Our goal is to forecast the effect of climate change on the distribution and abundance of big sagebrush in order to inform conservation planning, and sage grouse management in particular, across the Intermountain...

FY2015Collaborators are investigating the effect of low rise dams water supply, ecosystem functions and health, and habitat for a wide range of organisms, including sage grouse. They are assessing the economic cost and attitudes of ranchers and managers towards both low-rise dams and proposed re-introductions of beavers. Remote sensing is used to identify locations of incised streams across the Great Basin.

FY2015The Northwestern Great Basin ecoregion is one of the most intact ecosystems in the west. It is also a biological hotspot for migratory birds, greater sage-grouse and a stronghold for pronghorn antelope. However, altered fire regimes, invasive species, water scarcity, development, and climate change threaten the integrity of this landscape. Several efforts are ongoing for individual species, specific threats or sub-geographies, and over 60 existing plans and assessments have been identified for the region. This project will pull the pieces together to create a holistic view of shared priorities on the landscape.
