The Tongass National Forest has identified resources that are important to stakeholders and vulnerable to climate-related stressors. Cooperators will review an action plan and convene a workshop to be held in Southeast Alaska in 2016. The workshop will foster collaboration between scientists, managers, and stakeholders. Workshop goals include: sharing information about climate-related stressors and effects on NPLCC Priority Resources in the Tongass National Forest; developing strategic priorities for improving understanding, reducing risks, and increasing adaptive capacity and resilience; coordinating support for increasing knowledge and informing resource managers

This dataset contains small cutthroat trout lakes within Southeast Alaska. These are smaller lakes that do not produce cutthroat trout large enough to reach the 11-inch regional minimum size limit. Each of these lakes has a 9-inch minimum size limit, and bait is prohibited. Regionwide limits of 2 per day and 2 in possession apply. Currently there are seven lakes in Southeast Alaska with the small cutthroat lake designation. Please verify fishing regulations with current Alaska Department of Fish and Game Sport Fishing Regulations at the following link: http://www.adfg.alaska.gov/index.cfm?adfg=fishregulations.se_sportfish
This dataset contains polygons describing photo interpreted map classifications of the Tongass National Forest developed in 1978. The dataset's primary objective was to delineate major land types and their attributes. The land types were mapped at a polygon level - areas generally homogenous in character. Mapping was done to a 10 acre minimum except for non-commercial and non-forest types which were mapped to a 5 acre minimum. The classification identifies water as well as land. It segregates land into non-forest and forest. Polygons in forested areas were assigned a single, representative set of attributes; species composition, age, and volume class. Tim86 was updated in the 1980's (mostly in 1986) to reflect timber...
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 unit size is approximately 10 acres, though the average area for forested polygons is 60 acres. Additionally, CoverType is updated for new stands created through natural events or...
Data represent presence/absence for cedar decline occurrence. Cedar decline refers to the dying or decline of yellow-cedar (Chamaecyparis nootkatensis) forests in Southeast Alaska and is characterized by red or yellow foliage in trees currently dying, or by white-gray snags of old mortality. Mapped snags can be standing dead as long as eighty years. The data were collected via aerial sketch mapping techniques and recorded on 1:250,000 USGS base maps from 500-3000 foot above ground level(AGL) observations. Survey coverage has been most intense for forests adjacent to shorelines and waterways. Data are collected, refined and updated on an annual basis. This data represent not one year's mortality but the cumulative...

This cover dataset contains polygons which depict Riparian Management Areas and wind farm buffers (no cut areas) on the Tongass National Forest.
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,...

This dataset is used for cartographic representation of "double-line" streams where braided watercourses, wide channels and multi-channels occur on stream/river systems. This particular version of the dataset was developed to submit to the National Hydrography Dataset (NHD) As the SEAK Hydro database evolves, so to will the metadata for this dataset. Until noted otherwise, please reference this metadata for an older version of the source data. This dataset provides cartographic representation of "wide" linear water features of the Tongass National Forest in Southeast Alaska with the inclusion of some features from state and private lands.
The Preliminary Classification of Terrestrial Ecosystems in Southeast Alaska is based on 4 major data layers: USDA Forest Service Existing Vegetation database, the National Wetland Inventory, the USDA Forest Service Landforms and Karst from USFS soils and karst inventories. These layers were merged with auxillary sources from Landsat Enahnced Thematic Mapper (ETM) and supplemented with aspect and elevation from the Shuttle Radar Topography Mission Digital Elevation Model (SRTM DEM) . This master database retains all of the detailed features from each of these datasets to allow maximum flexibility for future researchers to use unique combinations of habitat variables that suit their subject of interest.
As the SEAK Hydro database evolves, so to will the metadata for this dataset. In the interim, please reference this metadata for an older version of the source data. This dataset contains polygons that depict lakes within the Tongass National Forest (not currently all of SE AK) that were derived from the USFS "Landstat" dataset.

This dataset displays PCT and CT second growth forest suitable for timber harvest in 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:Areas within 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, 5. potential habitat conservation areas removed using...
This dataset depicts clearcuts on the Tongass National Forest (Alaska, USA) prior to 2000. This dataset is part of a larger analysis of road building and timber harvest on the Tongass National Forest, compiled for the report Scientific Basis for Roadless Area Conservation (http://consbio.org/what-we-do/scientific-basis-for-roadless-area-conservation/?searchterm=tongass), pp 70-73. Prior to 1960, timber extraction was primarily accomplished from the ocean shore. Following 1960, due to increased road-building activity, inland forests were increasingly harvested. A spatial time-series analysis of road-building and clearcuts by decade, as depicted by this and other layers within this analysis, demonstrates this trend....
