FY2015The Great Basin Region, which covers much of Nevada, and portions of California, Oregon, Idaho, and Utah, managers are already confronting a changing climate and are beginning to make management decisions despite uncertainty in how climate change effects will manifest in the region. To support decision making, the Great Basin Landscape Conservation Cooperative (LCC) and the National Oceanic and Atmospheric Administration (NOAA) Regional Integrated Science Assessment Program (RISA) funded this project to explore how two scenario planning approaches might be used effectively with existing management planning processes and data sources and how to begin prioritizing adaptation strategies. The two approaches used...

FY2016Develop and utilize both correlative and experimental approaches to evaluate effects of different intensities of spring cattle grazing on sage-grouse habitat selection, insect abundance, and sage-grouse demographic and behavioral traits. Collect data and document the effects of different levels of spring cattle grazing intensity on:1) sage-grouse demographic traits; 2) abundance and biomass of arthropods; 3) sage-grouse nest concealment and other vegetation/habitat features.Analyze the relationship between cattle grazing and sage-grouse demography at multiple spatial scales and evaluate the effects of experimental changes in cattle grazing on sage-grouse reproductive parameters.

FY2014This project proposes to test the hypothesis that soil fungistasis (suppression of fungal pathogens by soil microbes in carbohydrate-limited soil) and its alleviation through natural carbohydrate augmentation (e.g., cheatgrass litter, leakage from cheatgrass roots) are the principal processes mediating patterns of cheatgrass die-off and recovery in die-off-prone areas.The project team will use laboratory, greenhouse, and field manipulative experiments to examine the effect of soil carbohydrates on cheatgrass disease incidence.

FY2013Pion (Pinus spp.) and juniper (Juniperus spp.) (PJ) currently occupy approximately 19 million hectars in the Intermountain West. Prior to 1860, approximately 66% of what is now woodland occurred as sagebrush plant communities.This watershed scale project: Documents the impact of PJ treatments in formerly sagebrush steppe communities on understory vegetation composition, hydrologic function, and surface runoff and soil erosion at the landscape scale. Expands the snow monitoring component to understand snow dynamics and timing of plant phenology in cut and uncut treatments. Secures expertise to analyze existing datasets.

FY2017This study addresses the need to develop treatments, soil amendments, and other site-preparation techniques that enhance germination, establishment, and development of healthy sagebrush communities. This study addressed the following objectives: (1) Determine whether seeded sagebrush established more frequently in fertile islands compared to burned shrub interspaces and locations where sagebrush was absent prior to the fire; (2) Determine whether the soil characteristics of sites and fertile islands within those sites influence sagebrush establishment patterns; and (3) Consider whether fertile island soil characteristics could be reporduced by manipulation post-fire soils in areas that had no pre-fire sagebrush....

FY2016Information on climate adaptation of native plants used in restoration is needed to help guide seed transfer from collection sites to restoration areas across the Great Basin. This project evaluates variation among populations planted together in common gardens of sagebrushes or bluebunch wheatgrass to achieve the goal.The need for seeds for sagebrush ecosystem restoration and rehabilitation projects has led to the transfer of seed across climate zones and hundreds of miles. Development and application of climate-based seed zones are needed to improve seeding success and return-on-investment. USGS, in collaboration with USFS, has accumulated considerable data on climate responses of key native (and cultivar)...

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...

FY2014Recent drought, change agents and the spectrum of greater management needs have highlighted the relative dearth of in situ weather and climate measurement stations in the Great Basin. Thus, interest has grown in supplementing or initiating atmospheric and hydrologic measurements.The purpose of this project was: To review the existing station networks in the context of management needs by providing examples of how climate observation gaps can be assessed Provide some guidelines for the placement of new or augmented stations.This project was funded as a target of opportunity.

FY2017The Integrated Rangeland Fire Management Strategy Actionable Science Plan places a high priority on assessing control measures for invasive annual grasses, which provide fuel for rangeland fire and impede restoration of desirable perennials. Weed-suppressive strains of the bacterium Psuedomonas fluoresens (P.f.) are an emerging but yet untested tool for selectively reducing these annual grasses. P.f. may suppress annuals for approximately 2-5 years, bridging the short-term action of herbicides and long-term resistance provided as native bunchgrasses recover. In 2015-2016, the USGS responded to a request from the Idaho sage grouse action group to establish a series of field-based experiments to assess the efficacy...

FY2014Avoiding cheatgrass dominance following tree-reduction treatments on woodland-encroached sagebrush communities is a priority for managers in the Great Basin. Perennial herbaceous and weedy annual cover have been related to site resilience after treatment and associated with soil climate regimes and site physical characteristics. Additional investigation of site characteristics associated with vegetation response will allow us to better decide which sites to treat and whether seeding is needed or not in conjunction with tree reduction treatments. Site-level planning also requires an understanding of how climate change may influence vegetation response to treatments. We propose to associate site-measured soil...
