Experts identify 21 key areas in Indian subcontinent for healthy tiger conservationNovember 14th, 2007 - 8:33 am ICT by admin
The remaining 129 protected areas do not have the potential to sustain high numbers of tigers. Nonetheless, these reserves could be capable of containing tigers over the long term if the landscape surrounding the reserves are better managed to reduce negative impacts.
The research that appears in the most recent edition of the journal Biological Conservation, said these protected areas have the potential to support between 58 percent and 95 percent of the subcontinent’s potential tiger capacity, estimated to be between 3,500 to 6,500 tigers.
“We were happy to find that the most important reserves identified in the study already have made tiger conservation a priority,” lead author Dr. Jai Ranganathan of the National Center for Ecological Analysis and Synthesis, was quoted, as saying.
The tiger is endangered in all of its natural habitats, a range stretching from India down into Southeast Asia as far as the island of Sumatra, and in the Russian Far East, and is listed as endangered according to both international and U.S. law.
In the absence of reliable data to produce a reliable estimate, tiger conservationists say the big cats may currently number between 1,500 to 4,000 animals in the four countries combined.
The study is a part of continuing efforts to conserve the tigers and their wild lands wherever they survive.
On a broader scale, WCS is currently working with the Panthera Foundation on an ambitious new program that calls for a 50 percent increase in tiger numbers in key areas over the next decade.
This new initiative, called “Tigers Forever,” blends a business model with hard science, and has already attracted the attention of venture capitalists who have pledged an initial 10 million dollars to go to specific projects to support the initiative.
Unlike earlier efforts to set tiger conservation targets that were mostly based on land cover maps, this study for the first time incorporated field data on tiger densities derived from the pioneering camera trapping work of WCS researcher Dr. Ullas Karanth and colleagues.
The study also assessed the impact of the landscape matrix surrounding the reserves using tiger population models based on measured and expected tiger densities.
Though no truly accurate global numbers exist, conservationists guess that 5,000 tigers remain in the wild. About 150 years ago, 100,000 tigers may have roamed throughout much of Asia. (ANI)
