- Abstract
- World Wildlife Fund Terrestrial Ecoregions is a polygon theme representing global terrestrial ecoregions. Ecoregions are defined as relatively large areas of land or water in the world containing a characteristic set of natural communities that share a large majority of their species, dynamics, and environmental conditions. This data set contains all terrestrial ecoregions, which include those of the Global 200. Global 200 ecoregions are a collection of the Earth's most outstanding and diverse terrestrial, freshwater, and marine habitats where the Earth's biological wealth is most distinctive and rich, where its loss will be most severely felt, and we must protect if we are to preserve the web of life. For more information, contact http://www.worldwildlife.org.
- Purpose
- World Wildlife Fund Terrestrial Ecoregions provides a global view of terrestrial ecoregions defined by the World Wildlife Fund Conservation Science Program, and can be used for geographic display and analysis at national and world levels.

- Data Quality Information
- Logical Consistency Report
- The shapefile is converted to SDC (Smart Data Compression) format using tools in ArcGIS. The SDC data set is then imported into a file geodatabase to verify, validate, and if needed repair the geometry.
- Completeness Report
- After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
- Horizontal Positional Accuracy Report
- The geospatial part of this data set is based on the Digital Chart of the World (1:1,000,000 scale) that has been generalized. Generalizing reduces positional accuracy and the tolerance was not recorded so the positional accuracy is not known.

- Entity Type Definition
- The polygons represent global terrestrial ecoregions defined as relatively large areas of land in the world that share a large majority of their species, dynamics, and environmental conditions. Ecoregions function effectively as conservation units because they encompass similar biological communities and because their boundaries roughly coincide with the area over which key ecological processes most strongly interact. These features can help conservation planners better achieve representation and persistence of biodiversity when developing conservation strategies for individual ecoregions.
