This dataset depicts sales of a non-mineral resource by the State of Alaska. These sales include timber sales in addition to sand and gravel sales. This shape file characterizes the geographic representation of land parcels within the State of Alaska contained by the Resource Sale category. It has been extracted from data sets used to produce the State status plats. This data set includes cases noted on the digital status plats up to one day prior to data extraction. Each feature has an associated attribute record, including a Land Administration System (LAS) file-type and file-number which serves as an index to related LAS case-file information. Additional LAS case-file and customer information may be obtained...
The original CoverType Dataset was clipped by the four Ranger Districts of interest:Â Thorne Bay, Craig, Wrangell, and Petersburg.Below is the information from the original dataset:CoverType is a photo-interpreted delineation of the Tongass National Forest by land type and timber cover type. Classification of lands was done sequentially: 1) land and water identified; 2) forested and non-forested areas were identified; 3) forested areas were classified by forest type and forest productivity; and 4) productive forest lands were further characterized by volume class, tree size, species composition. The original classifications were based on photo-interpretation of 1:15840 aerial photographs in 1978. The minimum map...
This dataset displays PCT and CT second growth forest suitable for harvest overlapping open, FS-roaded areas on the Craig, Petersburg, Thorne Bay, Wrangell and Ketchikan-Misty Ranger Districts of the Tongass National Forest. The Conservation Biology Institute performed GIS analysis identifying the following areas based on criteria specified by Mater Engineering and NRDC:Forest stands with at least some portion within (overlapping) 800 feet of USFS-operable roads where 1. commercial and precommercial thinning have previously taken place 2. on acreage suitable for timber harvest with less than 72% slope (based on prior Forest Service analysis) 3. with null suitability values removed, 4. karst formations removed,...
