Title: |
Ecoregions Database |
Purpose: |
World Wildlife Fund Ecoregions provides a global
view of mainly terrestrial ecoregions defined by the World Wildlife
Fund Conservation Science Program 1998 - 1999, and can be used
for geographic display and analysis at national and world levels |
Abstract: |
World Wildlife Fund Ecoregions represents global
terrestrial and freshwater ecoregions defined as relatively large
areas of land or water in the world that share a large majority
of their species, dynamics, and environmental conditions. It contains
the terrestrial habitats and some freshwater habitats of the Global
200 ecoregions, a collection of the Earth's most outstanding and
diverse terrestrial, freshwater, and marine habitats--areas where
the Earth's biological wealth is most distinctive and rich, where
its loss will be most severely felt, and where we must fight the
hardest for conservation. The data is from the World Wildlife
Fund Conservation Science Program 1998 - 1999. |

| BDI |
The biological distinctiveness index. It is based
on the species richness, endemism, rareness, etc |
THREAT |
The degree of threat to the ecoregion. Such threats
are from logging, conversion to agriculture/urbanization, etc |
FINAL |
The final assessment of the ecoregion as the estimated
threat to the ecoregion over the next 20 years. |
