Stream Temperature Modeling and Monitoring: Air Temperature Based Thermal Stream Habitat Model

    The Air Temperature Based Thermal Stream Habitat Model was originally developed from weather station information across the Columbia River basin in the Pacific Northwest. Multiple regression was used to predict mean annual air temperatures from elevation, latitude, and longitude with good success R^2 ~ 0.89). The model was developed as an alternative to PRISM data interpolations based on spline surface smoothing and should more accurately represent thermal conditions in stream valleys.

    Stream Temperature Modeling and Monitoring: Multiple Regression Stream Temperature Model

      This simple Stream Temperature Modeling and Monitoring approach uses thermograph data and geomorphic predictor variables from GIS software and digital elevation models (DEM). Multiple regression models are used to predict stream temperature metrics throughout a stream network with moderate accuracy (R^2 ~ 0.65). The models can provide basic descriptions of spatial patterns in stream temperatures, suitable habitat distributions for aquatic species, or be used to assess temporal trends related to climate or management activities if multiple years of temperature data are available.

      The Aquatic eDNAtlas Project: Lab Results Map - USFS RMRS

        The eDNA samples in the eDNAtlas database describe species occurrence locations and were collected by the U.S. Forest Service and numerous agencies that have partnered with the National Genomics Center for Wildlife and Fish Conservation (NGC) throughout the United States. The eDNAtlas is accessed via an interactive ArcGIS Online (AGOL) map that allows users to view and download sample site information and lab results of species occurrence for the U.S. The results are primarily based on samples analyzed at the National Genomics Center for Wildlife and Fish Conservation (NGC) and associated with geospatial attributes created by the Boise Spatial Streams Group (BSSG).

        The Range-Wide Bull Trout eDNA Project - USFS RMRS

          The bull trout (*Salvelinus confluentus*) eDNA survey results Online Map allows users to view the survey results in an interactive map by coupling 1) predictions from the range-wide, spatially precise Climate Shield model on the location of natal habitats of bull trout with 2) a sampling template for every 8-digit hydrologic unit in the historical range of bull trout, based on the probability of detecting bull trout presence using environmental DNA (eDNA) sampling. The map provides the ability to zoom in and look at an area of interest, as well as to create queries or select an area to download points as a shapefile.

          Arctic Peregrine Falcon Abundance on Cliffs Along the Colville River, Alaska, 1981-2002 and Covariate Input Files

            This data set consists of fourteen data files. Rcode_arctic_peregrine_abundance.R contains R code that was used to analyze Arctic peregrine falcon data collected between 1981 and 2002. The code primarily uses the R package "UNMARKED" and is based on the Dail-Madsen model for estimating population abundance. To run this code in an R environment, download the file and open it in an R interpreter (such as RStudio). The remaining files are all covariate matrices that act as inputs to the R code.

            Mt Hood National Forest GIS (Geographic Information Systems) data

              Located twenty miles east of the city of Portland, Oregon and the northern Willamette River valley, the Mt. Hood National Forest extends south from the strikingly beautiful Columbia River Gorge across more than sixty miles of forested mountains, lakes and streams to Olallie Scenic Area, a high lake basin under the slopes of Mt. Jefferson. These data sets were made using ESRI© ArcGIS.

              Northern Region (Region 1) Geospatial Data

                The Northern Region (R1) of the U.S. Forest Service uses ArcGIS Online to share maps, data, and applications for use by other federal agencies, partners, and the public. This gallery displays some of the web map applications developed by the Region and our Forests.

                Pacific Northwest Region (Region 6) Geospatial Data

                  The Pacific Northwest Region (Region 6) of the US Forest Service contains 17 National Forests, two National Scenic Areas, a National Grassland, and two National Volcanic Monuments, all within the States of Oregon and Washington. These national forests provide timber for people, forage for cattle and wildlife, habitat for fish, plants, and animals, and some of the finest recreation lands in the country. This database contains links to the Pacific Northwest Forests with GIS data currently available online.
