Last updated on 7/1/2011 12:55:48 PM.


This dataset is a spatial dataset of public and private lands and waters secured by a conservation situation that includes an explicit level of security from future conversion and current incompatible uses. Includes spatial data from TNC's Conservation Lands System (CLS) database, which is the legal database of record for all TNC land transactions (fee, easement, lease and deed restrictions).

Conservation Management Status (CMS) is a measure derived from the intent, duration and the effective management potential of spatial features of interest ("conservation situations") in the dataset. It is defined as a measure of the likelihood that an existing conservation situation is sufficient to secure biodiversity and allow for its persistence.

Data Input

This dataset was developed in partnership with the Conservation Biology Institute (CBI), whose efforts are closely aligned with the work of United States Geological Service (USGS) GAP Analysis Program (GAP) and the IUCN World Commission on Protected Areas. These organizations have developed valuable geospatial datasets that provide the most comprehensive collection of U.S. public lands protection and management data in the nation. Both the CBI Protected Areas Database (CBI PAD) and the GAP Analysis Program (GAP) Management Status Classification provide the foundation for collecting, mapping, and managing information on this measure. This dataset builds on the work of these organizations by using data they have created and maintaining the standards they have set, while adding new layers of information that more directly meets TNCs needs to measure and track the status and progress of biodiversity conservation.

TNC Lands GIS Team Contacts

The WFDSS application is "data rich". It requires data which is spatially oriented and graphically displays information to support wildland fire and other natural resource decisions. Due to the type and number of interagency spatial data sets required in April 2009 an interagency GIS Team was formed to provide data support for WFDSS. This Team is responsible for acquiring, consolidating, and validating their agency spatial and tabular data. In addition this team developed and maintained communications among local, regional, and national agency personnel to improve the collection process and provide explicit guidance on data needs. The members of the WFDSS GIS Team are:
