Combined Thickness of the Modeled Wanapum Basalt and Vantage-Latah Interbed Geomodel Units (wnthk_f)
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The wnthk_f grid represents the modeled combined thickness of the Wanapum Basalt and the Vantage/Latah interbed geomodel units at a 500 foot resolution. It is one grid of a geomodel that consists of eleven grids and a spatial extent polygon shapefile. As part of a U.S. Geological Survey Groundwater Resources Program study, a three-dimensional geomodel was constructed for approximately 53,000 mi2 of the Columbia Plateau in Washington,...
This GIS dataset is part of a suite of wildlife habitat connectivity data produced by the Washington Wildlife Habitat Connectivity Working Group (WHCWG). The WHCWG is a voluntary public-private partnership between state and federal agencies, universities, tribes, and non-governmental organizations. The WHCWG is co-led by the Washington Department of Fish and Wildlife (WDFW) and the Washington Department of Transportation (WSDOT). This dataset quantifies current wildlife habitat connectivity patterns for the Columbia Plateau Ecoregion in Washington, Oregon, and Idaho. Available WHCWG raster data include model base layers, resistance, habitat, cost-weighted distance, and landscape integrity. Grid cell size is 90 m...

These data are the final landscape permeability data as described in the report "Conserving Nature's Stage: Identifying Resilient Terrestrial Landscapes in the Pacfic Northwest."Permeability refers to the connectivity of a focal cell to its ecological neighborhood when it is viewed as a source; in other words, it asks the question: “to what extent are ecological flows outward from that cell impeded or facilitated by the surrounding landscape?” Thus,permeability starts with a focal cell and looks at the resistance to ecological flow outward in all directions through the local neighborhood. As resistance increases, flow is impeded or stopped altogether. Areas of no resistance allow the flow to proceed until a user-specified...

The catastrophic, explosive eruption of Mount St. Helens, Washington, on May 18, 1980, is the most well-known eruption of the volcano. Less well known is the May 18th eruption marked the beginning of a period of eruptive activity that lasted through 1986. From October 1980 through October 1986, a series of 17 dome-building episodes added millions of cubic meters of lava to the crater floor. Most of the growth occurred when magma extruded onto the surface of the dome, forming short (650 to 1,300 feet), thick (65 to 130 feet) lava flows. This data release is a 1-meter resolution digital elevation model (DEM) and a corresponding hillshade raster derived from a previously unpublished 1:2,000 scale topographic contour...
The purpose of this project is to use existing climate change datasets from the Climate Impacts Group (CIG) to summarize the the projected climate change impacts to United States Forest Service (USFS) lands in Oregon and Washington (Figure 1). Stakeholders in the Forest Service of this region were particularly interested in the variables that are likely to impact freshwater aquatic species, including projected changes in water availability, snowpack, and flood and low flow severities. Our objective is to summarize climate and hydrologic projections for USFS lands in Oregon and Washington. Since individual national forests may contain numerous distinct ecological regimes and cross hydrologic boundaries, averaging...
The NetMap concept is based on standardized, contiguous digital map databases that interact with a plug & play analysis tool library (erosion, stream temperature, in-stream wood etc.) to create customizable analysis platforms for decision support in a wide range of natural resource activities. Refer to the 2009 American Geophysical Union article on “the future of applied watershed science at regional scales” for additional information (available for download at the bottom of NetMap’s home page). The uniform, contiguous and attributed stream map databases can be downloaded, and then adjusted with respect to locations of channel heads, drainage density and the length scales of stream networks (default stream segment...
For his MS thesis, Brendan Rogers used climate data from the PRISM group (Chris Daly, Oregon State University) at a 30arc second (800m) spatial grain across the western 2/3 of the states of Oregon and Washington to generate a climatology or baseline. He then created future climate change scenarios using statistical downscaling to create anomalies from three General Circulation Models (CSIRO Mk3, MIROC 3.2 medres, and Hadley CM 3), each run through three CO2 emission scenarios (SRES B1, A1B, and A2).
This tabular data set represents the soil pH as processed from STATSGO2 database compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. The source data was produced by the United States Geological Survey (Wieczorek, 2019). Soil pH units are approximately the negative of the base 10 logarithm of the molar concentration, measured in units of moles per liter, of hydrogen ions. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. Reach catchment information characterizes data at the local scale. Reach catchments...
This tabular data set represents the percent of land cover classes from the 2011 National Land Cover Dataset compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is the "National Land Cover Database 2011" produced by the United States Geological Survey (Homer and others, 2011). Units are percent. The "National Land Cover Database 2011" (NLCD 2011) is a 16-class (additional four classes in Alaska only) land cover classification scheme that...

The dataset contains 3 maps that show the current and predicted range of Lodgepole pine (Pinus contorta) in the Pacific Northwest region. The layers include: 1) the species range modeled under current climate conditions for 1950-75 2) a continuous model of the predicted range for 1950-2006 and 3) potential range expansion and contraction from 2000-2009.
A warming climate could profoundly affect the distribution and abundance of many fishes. Bull trout (Salvelinus confluentus) may be especially vulnerable to climate change given that spawning and early rearing are constrained by cold water temperatures creating a patchwork of natal headwater habitats across river networks. Because the size and connectivity of patches also appear to influence the persistence of local populations, climate warming could lead to increasing fragmentation of remaining habitats and accelerated decline of this species. We modeled the relationships between (1) the lower elevation limits of small bull trout and mean annual air temperature and (2) latitude and longitude across the species'...
