    The issue is explored in a recent article in New Scientist | 
The Red List, produced   by the International Union for Conservation of Nature (IUCN), is widely   recognised as the leading global assessment of extinction risk, and provides an   indication of which species are most in need of conservation action. The Red   List is also increasingly being used to monitor the success of conservation   initiatives, such as the Convention on Biological Diversity.  
  
  However, the   process of classifying species according to the Red List categories is often   highly uncertain, because of the lack of accurate information about the   conservation status of many species. This issue is explored in a recent article   in New Scientist, which questions whether the Red List is flawed (http://www.newscientist.com/article/mg20126992.700-flawed-red-list-putting-species-at-risk.html
).   
  
  The article draws upon a series of papers in the journal Endangered Species Research
, including   recent research by Prof. Adrian Newton, of the Centre for Conservation Ecology   and Environmental Change, which reviews recent progress in Red Listing the   world's tree species. http://www.int-res.com/abstracts/esr/v6/n2/
