Freshwater Ecoregions of the Mekong Basin

This dataset was created from Hydrosheds level 3 dataset to represent approximate freshwater ecoregions of the Mekong basin. Based upon the WWF freshwater ecoregions dataset which is defined as, a large area encompassing one or more freshwater systems that contains a distinct assemblage of natural freshwater communities and species. The freshwater species, dynamics, and environmental conditions within a given ecoregion are more similar to each other than to those of surrounding ecoregions and together form a conservation unit.

Positional Accuracy This dataset contains inaccuracies as it is a simply an export of relevant hydrosheds that lay within the approximate boundaries of the ecoregions dataset and therefore is only an approximation and can not be used as definitive boundaries for the freshwater ecoregions
Logical Consistency There are no known issues with logical consistency.
Completeness This dataset is not complete.
Process Step Hydroshed areas were selected based upon the largest area that fall within each freshwater ecoregion. These area's were dissolved to create individual shapes before merging into one area covering the Mekong basin.
