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)...
Using Soil Climate and Geospatial Environmental Characteristics to Determine Plant Community Resilience to Fire and Fire Surrogate Treatments
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...
How Will Coldwater Fish Survive in a Warming Future? Identifying Life-Stage Specific Use of Coldwater Refugia in the Klamath Basin and Willamette River
Oregon’s Upper Klamath Basin is one of the warmest watersheds in the Pacific Northwest. Despite its naturally warm waters, the basin supports abundant redband trout. These are some of the largest-bodied trout in the entire U.S., and are a culturally and economically important species, providing the last remaining subsistence fishery for the Klamath Tribes and drawing recreational anglers. The ability of this coldwater species to survive in one of the region’s warmest watersheds could hold valuable clues for conservation in the face of warming global temperatures, which represents one of the biggest threats to North America’s coldwater fish. Previous research has found that redband trout rely heavily on spring-fed...
