patrick,
Thnx, but I was aware of this. If you read it carefully you will find that the research has centered on the Wanglang panda reserve. Where 65 pandas were found through DNA dung analysis, more than twice the number previously counted. Now, they infer that if these findings were replicated over the entire panda range and reserves, their number would be more in the range of 3,000 individuals.
However, given the secretive nature of the panda, I can well imagine that their number is much greater than the actual sightings of pandas have suggested. Thus I look with great interest to the research being extended to other panda reserves and the results confirming earlier findings at Wanglang.
Hopeful signs, but yet to be .. fully corroborated.
