The GAP Land Cover data set contains several categories that represent human land use: Current and Historic Mining Activity, Developed Urban, Herbaceous Agricultural Vegetation and Recently Disturbed or Modified. This layer package shows the four categories in isolation from the complete data set, and converted to a shapefile format. The symbology is based on the National Vegetation Classification (NVC) level "formation", which is the 3rd level of thematic resolution in the GAP data set. The GAP GIS layer has been clipped to the boundary of the SRLCC. There is also an Excel table showing each category's percent of the total SRLCC area. From GAP land cover metadata: "this dataset combines the work of several different...

This dataset compiles land ownership and management data from state and federal agencies to create a map showing ownership, management, and conservation status of all land in Alaska. State, federal, and private lands, including Native corporations and Native allotments, are included. Conservation status describes the degree to which land, particularly public land, is legally designated and explicitly managed for biodiversity conservation. The most common classification, developed by the USGS GAP Program (www.gap.uidaho.edu), classifies land management types into four conservation status categories according to the degree to which the land is explicitly managed for conservation. In general, conservation status 1...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
