Biodiversity Conservation of the World's Lakes: A Preliminary Framework

+ SIGNETS

LIEN: http://www.worldlakes.org/Biodiversity.htm

Description

This report suggests a preliminary methodology for identifying lakes, out of approximately five million that exist worldwide, with the most significant biodiversity in order to maximize the value of lake conservation work and funding. Much can be done to halt water diversion, invasive species, accelerated eutrophication, toxic contamination, sediment inundation, over-utilization of natural resources, global climate change and fragmented lake management, but the work is difficult and expensive, and needs to be prioritized to achieve meaningful progress. Two hundred and fifty lakes in 73 countries are identified as initial priorities for biodiversity conservation based on the available but very limited data on fish, mollusc, crab, shrimp, and bird biodiversity supported by each lake, and the rarity of certain representative types of lakes.
