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...

This data set consists of polylines representing groundwater-level altitude contours, 1982, for middle Humboldt River basin, north-central Nevada as published on plate 2, figure 3 in the U.S. Geological Survey Water-Resources Investigations Report 98-4209 titled "Hydrogeologic framework and ground-water levels, 1982 and 1996, middle Humboldt River basin, north-central Nevada," 1999. A subset of the contours were published as part of a larger data set representing water-table contours for Nevada (Buto and others, 2006). The remaining contours have been added to complete this data set.

These datasets provide early estimates of 2022 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a bi-weekly basis from May to early July. The EAG estimates are developed within one week of the latest satellite observation used for that version. Each bi-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 Landsat...

FY2014There is increasing interest in climate change adaptation, particularly since the release of the Presidents Executive Order on Climate Preparedness in November, 2013, yet many field staff remain uncertain how to put adaptation into practice. Our goal with this project is to bridge the gap between the wealth of high-level climate adaptation guidance and the field staff who carry out specific regulatory processes, specifically Habitat Conservation Plans. Following best practices from the literature on linking science and management, we will begin with a focus on what people do rather than on the climate science. We will map the current HCP development and approval process in Region 8, identify where and how...

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...

These contours represent static groundwater levels based on depth-to-water measurements made at 165 monitoring wells during water years 2016-2020 in Smith Valley and Mason Valley, Nevada. For each monitoring well, the median groundwater-level altitude during the five-year period (2016-2020) was used for developing the groundwater-level contours. Depth-to-water measurements were collected by the USGS and the Nevada Division of Water Resources (NDWR).

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...

FY2017Increasing effectiveness of post-fire treatments is a management priority, such as is emphasized in Secretarial Order #3336 on rangeland fire and restoration, which prescribes a programmatic, longer-term approach that accommodates the layering of different treatments in sagebrush-steppe rangelands. The phasing of treatments by applying them in different post-fire years is an important part of wildfire response that, along with timing of livestock grazing resumption, likely affects overall project success - but is yet under studied. This projects objective is to determine the incremental gains in increasing desirable perennials and decreasing exotic annual grasses with the phasing of land management actions...

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...
