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.

    Shawnee National Forest Geospatial Data

      GIS data is available on the Forest’s FTP site in the form of “shape files” or layers and is available free for downloading. To utilize these data layers you will need a program that uses the Geographic Information System (GIS) such as ESRI’s ArcMap, ArcView or the free map reading program ArcGIS Explorer. ArcGIS Explorer has tools that let you zoom in/out, print the map, and query data. It also has map tips to identify features, and a help menu. Included is a list of GIS data files available for the Shawnee National Forest. These GIS data files are updated on a continuing basis.

      Data from: Effects of conifer treatments on soil nutrient availability and plant composition in sagebrush steppe

        Conifer control in sagebrush steppe of the western United States causes various levels of site disturbance influencing vegetation recovery and resource availability. The data set presented in this article include growing season availability of soil micronutrients and levels of total soil carbon, organic matter, and N spanning a six year period following western juniper (*Juniperus occidentalis* spp. *occidentalis*) reduction by mechanical cutting and prescribed fire of western juniper woodlands in southeast Oregon. These data can be useful to further evaluate the impacts of conifer woodland reduction to soil resources in sagebrush steppe plant communities.
