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...

FY2013Cheatgrass die-offs are unexplained instances of stand failure observed in areas of Nevada and Utah, where cheatgrass fails to grow even though it has been a dominant component of plant communities in the past. The goals of this project are to:1) provide information on the size and extent of historic (1985 - 2012) die-offs in the Winnemucca area using satellite imagery, and 2) determine if die-offs are restoration opportunities by planting and monitoring local and commercially available native grasses in die-off areas.Support is requested to fund monitoring of the restoration project through a second growing season and to develop predictive spatial models of die-off from analysis of satellite imagery and GIS...

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.

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.

FY2014The project team surveyed land managers working on invasive weeds in the west. These surveys provided information for the Western Association of Fish and Wildlife (WAFWA) Wildfire and Invasive Species Initiative Working Group. The survey results and other findings were used to inform a report titled Invasive Plant Management and Greater Sage-Grouse Conservation,published last spring.

FY2013“The loss of big sagebrush (Artemisia tridentata Nutt.) on sites disturbed by fire has motivated many restoration seeding and planting efforts. However, the resulting sagebrush establishment is often lower than desired, especially in dry areas. Sagebrush establishment may be increased by addressing factors such as seed source and condition or management of the plant community. The research team assessed initial establishment of seeded sagebrush and four populations of small outplants (from different geographies, climates, and cytotypes) and small sagebrush outplants in an early seral community where mowing, herbicide, and seeding of other native plants had been experimentally applied. No emergence of seeded...

FY2011Aspen populations are in decline across western North America due to altered fire regimes, herbivory, drought, pathogens, and competition with conifers. Aspen stands typically support higher avian biodiversity than surrounding habitats, and maintaining current distributions of several avian species is likely tied to persistence of aspen on the landscape. We are examining effects of climate change on aspen and associated avian communities in isolated mountain ranges of the northern Great Basin, by coupling empirical models of avian-habitat relationships with spatially-explicit landscape simulations of vegetation and disturbance dynamics (using LANDIS-II) under various climate change scenarios. We are addressing...

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.

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)...

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...
