<DIV STYLE="text-align:Left;"><DIV><P><SPAN>This map is a simplified representation of the eight Biogeographical Realms of the world. This global map provides a useful general framework for conducting biogeographical or macroecological research. The realms are based originally on ecoregion delineations on hundreds of previous biogeographical studies, and refined and synthesized existing information in regional workshops over 10 years to assemble the global dataset. Ecoregions were then nested within two higher-order classifications to produce biomes (14) and biogeographic realms (8). Together, these nested classification levels provide a framework for comparison among units and the identification of representative habitats and species assemblages.</SPAN></P></DIV></DIV>

This dataset was created to allow complete diagrammatic representation of the world's Biogeographical Realms on a map. The original data only showed boundaries which crossed land masses. Such data was extremely intricate and detailed. To represent this information clearly on a global map, original data was much simplified (by eye) where it crossed land masses and was extended across the oceans in the same way. Efforts were made to enable features to link across at longitude 180 degrees so that the information can be shown with a central meridian of other than 0 degrees (Greenwich).

Two-letter code for Realm which links to WWF Terrestrial Ecoregions dataset
The dataset is based on the WWF Terrestrial Ecoregions dataset and was created with illustrative purposes in mind. The terrestrial boundaries have been considerably simplified and boundaries which cross marine areas were digitised by eye from a sketch map.
