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...

FY2013The increase in large wildfires at a time when habitat for Greater Sage Grouse and other species dependent on big sagebrush has also increased has led to substantial needs for big sagebrush seeds. Significant decisions on which sagebrush seed to use and on management treatments that affect competing herb layers on the same restoration sites affect the trajectory of habitat.This project will evaluate how seed source, specifically genotype and climate-of-origin, interact with landscape-scale and replicated treatments (fencing, herbicide application, mowing, and seeding).

FY2010In addition to regional Science and Traditional Ecological Knowledge projects that the Great Basin LCC (GBLCC) supports, GBLCC staff lend technical expertise to a range of projects and have contributed to important regional publications on a range of subjects. These publications range in type from textbooks, to management-oriented science and conservation plans, to scientific papers and have covered subjects like wind erosion following fire, soil microbiota response to drought, plant community resilience to invasive species, and alpine plant communities. In many cases these publications form foundations for scientifically-informed management strategies across the Great Basin.

FY2011Increasingly large wildfires in the Great Basin and Columbia Plateau have led to large dust storms in areas historically without them. Large dust storms have adversely affected human health, energy production operations, soil fertility, and mountain snowpack hydrology. USGS research efforts have investigated the causes and consequences of post-fire dust storms. Publications from this work are being used by managers with the Bureau of Land Management, Department of Energy, and other land managers to develop management practices that will minimize dust production.

FY2013Shrub-dominated ecosystems of the Great Basin are being threatened by disturbances, typically wildfire followed by encroachment of invasive plants (e.g., cheat grass). To mitigate these threats and future changes in the climate to big sagebrush (Artemisia tridentata), restorationists require a knowledge base and tools to inform them of the most appropriate seed sources to plant to greatly enhance the success of restoration under contemporary and future climates. We propose to develop climate-responsive seed transfer zones based on associating plant quantitative traits and ecophysiological data from common gardens to the climate of the seed source.

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...

This project aimed to contribute to effective decision making in the region for the scientific community and general public. Resource managers in the Great Basin are dealing with significant questions regarding how best to make decisions in the natural and human systems in response to climate change. Vulnerability assessments and other tools are used for climate change adaptation, but their effectiveness is not widely understood or examined. Assessing these tools for their utility and for their ability to translate science into accessible and available information for users, including the general public, is critical for the future viability and sustainability of the Great Basin. This project applied social and policy...

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...
