We evaluated sagebrush on 24 post-fire seeding sites encompassing >50,000 acres on the Snake River Plain in the Northern Great Basin, specifically in southwest Idaho. Sites were initially identified using the Land Treatment Digital Library (LTDL; http://greatbasin.wr.usgs.gov/ltdl/; and Inciweb fire information (http://inciweb.nwcg.gov/) websites to identify seeding projects located in predominantly Wyoming big sagebrush sites (2,500 to 4,000 feet ASL; 2 sites also had A.t. vaseyana, 2 other sites had only A.t. vaseyana) that (1) had burned and were seeded within the year following fire, from 1987-2010, (2) but had not burned since, and (3) had information on seed sources. Standard USDA species abbreviations are...

The datasets in these child pages are continuous parameter grids (CPG) of evapotranspiration data for March through September, years 2000 through 2015, in the Pacific Northwest. Source evapotranspiration data was produced using the operational Simplified Surface Energy Balance (SSEBop) model.
The U.S. Geological Survey (USGS) has developed the PRObability of Streamflow PERmanence (PROSPER) model, a GIS raster-based empirical model that provides streamflow permanence probabilities (probabilistic predictions) of a stream channel having year-round flow for any unregulated and minimally-impaired stream channel in the Pacific Northwest region, U.S. The model provides annual predictions for 2004-2016 at a 30-m spatial resolution based on monthly or annually updated values of climatic conditions and static physiographic variables associated with the upstream basin (Raw streamflow permanence probability rasters). Predictions correspond to pixels on the channel network consistent with the medium resolution National...

Managing species and habitat in a changing climate requires locally specific information about expected changes in the physical environment, key stressors and related ecological changes. Federal investments have supported the development of a significant scientific knowledge base detailing potential future conditions for many Northwest ecosystem types and geographies. Yet scientists, managers and other decision makers continue to be challenged by the difficulty of efficiently assessing the current state of understanding regarding both impacts and pathways for adaptation. For example, while the most recent Washington and Oregon State Wildlife Action Plans included detailed consideration of climate change-related...

Abstract: Wetlands in the remote mountains of the western US have undergone two massive ecological “experiments” spanning the 20th century. Beginning in the late 1800s and expanding after World War II, fish and wildlife managers intentionally introduced millions of predatory trout (primarily Oncorhynchus spp) into fishless mountain ponds and lakes across the western states. These new top predators, which now occupy 95% of large mountain lakes, have limited the habitat distributions of native frogs, salamanders, and wetland invertebrates to smaller, more ephemeral ponds where trout do not survive. Now a second “experiment” – anthropogenic climate change – threatens to eliminate many of these ephemeral habitats...

Abstract (from http://www.sciencedirect.com/science/article/pii/S0169534715000075): Extrinsic factors influencing evolutionary processes are often categorically lumped into interactions that are environmentally (e.g., climate, landscape) or community-driven, with little consideration of the overlap or influence of one on the other. However, genomic variation is strongly influenced by complex and dynamic interactions between environmental and community effects. Failure to consider both effects on evolutionary dynamics simultaneously can lead to incomplete, spurious, or erroneous conclusions about the mechanisms driving genomic variation. We highlight the need for a landscape community genomics (LCG) framework to...

Abstract (from Wiley Online Library): As evidenced by past climatic refugia, locations projected to harbor remnants of present‐day climates may serve as critical refugia for current biodiversity in the face of modern climate change. We mapped potential climatic refugia in the future across North America, defined as locations with increasingly rare climatic conditions. We identified these locations by tracking projected changes in the size and distribution of climate analogs over time. We used biologically derived thresholds to define analogs and tested the impacts of dispersal limitation with 4 distances to limit analog searches. We identified at most 12% of North America as potential climatic refugia. Refugia extent...

Over 50% of commercial and recreationally important fish species depend on coastal wetlands. In the Pacific Northwest, coastal wetlands, where the ocean meets the land, are highly productive areas that support a wealth of wildlife species from salmon to ducks. The tidal marshes, mudflats, and shallow bays of coastal estuaries link marine, freshwater, and terrestrial habitats and provide economic and recreational benefits to local communities. However, wetlands in this region and elsewhere are threatened by sea-level rise and other climate-related changes. According to a USFWS and NOAA report, between 2004 and 2009, 80,000 acres of wetland were lost on average each year, which is a significant increase from the previous...

Tribal communities’ traditions, identities, and economies rely heavily on local natural resources, making tribes especially vulnerable to climate change impacts, including changes in seasonal patterns and the potential loss of culturally and economically important species. The goal of this project was to build tribal capacity in the Pacific Northwest to successfully plan for and adapt to the effects of climate change. The funds associated with this project supported the Affiliated Tribes of Northwest Indians (ATNI) Tribal Leaders Summit on Climate Change held on March 10-11, 2015 in Portland, Oregon. The summit gathered tribal leaders to discuss climate change impacts; share tribal strategies, plans, and policies;...

Projected current and future distributions of Abies amabilis (Pacific silver fir), Abies grandis (Grand fir), Abies procera (Noble fir), Acer macophylla (Big leaf maple), Larix lyallii (Subalpine larch), Larix occidentalis (Western larch), Pinus albicaulis (Whitebark pine), Quercus garryana (Garry oak), Taxus brevifolia (Pacific yew), Thuja plicata (Western red cedar) based on empirical bioclimatic models. Tree distributions models were built using 42 climate and bioclimatic variables from Climate Western North America climate dataset (www.climatevulnerability.org). I used random forest to project USGS range maps (http://esp.cr.usgs.gov/data/little/) for historical (1961-1990) and five general circulation models...
A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study by the U.S. Geological Survey.
These files contain all of the source USGS/EPA taxa, temperature, and percent abundance of urban and agricultural land cover within the watershed upstream of the sampling site data used to calculate taxa specific macroinvertebrate optimal temperatures and tolerances. They also contain a taxa specific list of temperature optima and tolerances generated from the data contained in source USGS/EPA data.

Mean modeled snow-water-equivalent (meters) on April 1 for the T2 climate change scenario. T2 scenario: the observed historical (reference period) meteorology is perturbed by adding +2°C to each daily temperature record in the reference period meteorology, and this data is then used as input to the model.

This dataset delineates wetland ponds and emergent wetland vegetation in Mt. Rainier National Park. It was created through object based image analysis of high resolution imagery from 2006 and 2009 and LiDAR data acquired in the fall of 2008. Riparian wetlands are not included in this dataset. Accuracy is only verified for wetland ponds in the subalpine region. Forested wetlands, riparian wetlands, and emergent vegetation were only visually assessed. This data maps all wetland habitat, but was primarily used to locate and delineate amphibian habitat in Mt. Rainier National Park.
