The different terrestrial biodiversity priority setting exercises analyzed can be reasonably assessed comparatively from an ecoregional perspective since they basically use the same ecoregional cartographic base for Latin America and the Caribbean. Nevertheless, the Global 200 utilizes updated ecoregions (Olson and Dinerstein, 1997) which do not match precisely the The World Bank’s ecoregions (Dinerstein, 1995) utilized in all other exercises. The major difference amongst them resides in the level at which the prioritization exercise was carried out, which provides the best detail in the World Bank exercise.
