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...

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...

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...

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...
