Conservation Biology Institute selected closed USFS roads from the "Roads with Core Attributes" dataset based on the following criteria:Roaded areas for closed roads were determined based on the NFS definition:"ROUTE_STATUS" = 'EX - EXISTING' AND "JURISDICTION" = 'FS - FOREST SERVICE' AND "SYSTEM" = 'NFSR - NATIONAL FOREST SYSTEM ROAD' AND ("OPER_MAINT_LEVEL" = '1 - BASIC CUSTODIAL CARE (CLOSED)')Original metadata: A route feature stores the spatial locations (geography) of the road. These feature classes have an (M) value or measure on their vertices. A route system depicts all roads within or in close proximity to an administrative unit. A road is a motor vehicle travel way over 50 inches wide, unless classified...
This dataset depicts roads built on the Tongass National Forest prior to 1960. 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://www.consbio.org/cbi/projects/show.php?page=roadless/roadless.htm), pp 70-73. Road segments from a US Forest Service roads layer were attributed to the most likely decade in which the road was built, as determined by an analysis of connectivity to clearcuts on the Tongass National Forest from that decade. It was assumed that following 1960, harvests required access to mills or extraction sites, and thus roads connecting to them were most likely built...
This geospatially explicit vector-based polygon dataset identifies 85 terrestrial ecological subsection delineations present in Southeast Alaska and the Tongass National Forest. Within each subsection one can expect to find a relatively consistent occurence and distribution of vegetation types. Due to the hydrologically-influenced geomorphology of Southeast Alaska specific key indicators of physiography, lithology, and surface geology were employed to systematically distinguish terrestrial ecosystems.
A depiction of the boundary that encompasses a Ranger District. The original dataset was clipped to display select ranger districts within the Tongass National Forest.
Created by the Roadless Rule (WO-Group). It's the Law. This coverage contains the true inventoried roadless area and it will not change. Use this feature class for Roadless. http://www.fs.usda.gov/wps/portal/fsinternet/!ut/p/c5/04_SB8K8xLLM9MSSzPy8xBz9CP0os3gjAwhwtDDw9_AI8zPwhQoY6IeDdGCqCPOBqwDLG-AAjgb6fh75uan6BdnZaY6OiooA1tkqlQ!!/dl3/d3/L2dJQSEvUUt3QS9ZQnZ3LzZfMjAwMDAwMDBBODBPSEhWTjBNMDAwMDAwMDA!/?ss=119930&navtype=BROWSEBYSUBJECT&cid=null&navid=151150000000000&pnavid=151000000000000&position=BROWSEBYSUBJECT&ttype=main&pname=Roadless-%2520Maps
A route feature stores the spatial locations (geography) of the road. These feature classes have an (M) value or measure on their vertices. A route system depicts all roads within or in close proximity to an administrative unit. A road is a motor vehicle travel way over 50 inches wide, unless classified and managed as a trail. This feature is only SPATIAL ROAD DATA, other data (open, closed, jurisdiction, maintenance level) is stored in INFRA. Used to link spatial roads to INFRA data, ROAD NO., BMP, EMP and Calibration. Routed roads are a single spatial line, all have data in INFRA and this data must be attached. Routed roads need to have INFRA data table attached by use of R10 Geospatial Interface (GI) tool and...

Operable roads were buffered by 800ft by Conservation Biology Institute (CBI).Operable roads were selected by CBI from the "Roads with Core Attributes" dataset based on the following criteria:Roaded areas for operable roads were determined based on Sheila Sporesâ definition: Route status = existing Jurisdiction = forest service System = NFSR Oper_Maint_Level of â2â and above, which excludes roads assigned â 1 â Basic Custodial Care (Closed)â.Original metadata: A route feature stores the spatial locations (geography) of the road.

This dataset displays the boundaries of Intact Forest Landscapes for the islands in the Tongass region of the state of Alaska. Intact Forest Landscapes for islands are defined as areas at least 500 hectares that are absent of human disturbance visible on satellite imagery (e.g., roads, logging, mining, settlement). For more information, see the full report, available on the Global Forest Watch website (www.globalforestwatch.org), or the Conservation Biology Institute website (http://www.consbio.org/cbi/projects/show.php?page=alaska).

The original dataset was modified by adding a field for calculating stand age. Calculations were based on dates listed in Date_Origin field of original dataset. The dataset is styled based on the stand age. Original dataset description:Depicts the area of activities within or in close proximity to an administrative unit. The ActivityPolygon layer is updated for new treatment units and will display the gross boundary of the unit as well as the retained sub-units. Units being managed by the US Forest Service are all that is reliably displayed on this layer.

This dataset is used to denote USFS Land Use Designations (LUD) on the Tongass National Forest. Chapter 3, of Land and Resource Management Plan includes the complete management prescription for the 19 LUDS used in the Forest Plan. Please refer to the following document for further information:Â https://fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5367422.pdfNote: Private land was taken out from this layer. Before doing any calculations, users will need to overlay with currrent ownership.
