Terrestrial Ecoregions Base Global Dataset Request
The base global data set (BGDS) is available for download as an Excel spreadsheet. It has been compressed using WinZip (www.winzip.com) and is 558 KB in size.
This dataset was generated by intersecting multiple biological, environmental and population coverage's of the world and using, using spatial analyses and simple statistics. A separate report contains a detailed description of the processes involved in calculating the values in the BGDS, notes and explanations about some issues encountered during the analyses and a thorough description of each output variable. All the variables calculated were summarized for each of the 827 terrestrial ecoregions (Olson et al 2001), and were compiled into a spreadsheet for further use
This database is available for use for valid scientific, conservation, and educational purposes. We ask that you credit the Terrestrial Ecoregions data as follows:
