2003 UN List of Protected Areas

This is the thirteenth list produced by the United Nations since 1962, and the first version to attempt a comprehensive presentation of all the world's known protected areas.  The introductory text presents an analysis and the accompanying CD lists more than 102,000 sites covering 18.8 million square kilometers.  Significant progress has been made in conserving representative areas of the world's terrestrial biomes, although some, including Lake Systems and Temperate Grasslands, remain under-represented.  It is an essential reference document for all who want to understand the progress made in responding to the challenges of biodiversity loss and other environmental threats around the world.
