Asia's tigers could get big boost from small changes
November 5, 2007
Examining 157 reservers throughout the Indian subcontinent, the study found that 21 protected areas meet the criteria needed to support large healthy tiger populations. The research suggests that these protected areas could potentially support 3,500 to 6,500 tigers, up from the current estimate of 1,500 to 4,000 cats.
"We were happy to find that the most important reserves identified in the study already have made tiger conservation a priority," said the lead author Dr. Jai Ranganathan of the National Center for Ecological Analysis and Synthesis.

Conservationists estimate that around 5,000 tigers exist in the wild today--down from 100,000 a century ago.
