It is also important to understand that once more accurate data is available for those countries without national surveys, this latest global estimate will change. Estimations based on guesswork have often been exaggerated, as we saw in Bangladesh whose estimate was while their national tiger survey found tigers.
Equally there is no current data available for Myanmar, however wild tigers are believed to be present in certain areas. It is crucial that governments carry out regular tiger surveys so the global estimate is accurate. Once we know how many tigers we have and where they are, countries can protect them — and with protection comes increased numbers.
Four tiger biologists issued a Statement of Concern by Tiger Biologists questioning the source and credibility of the data used to compile the new global tiger population figure. The full WWF response can be read here. This is incorrect.
No report was published and the figure was compiled using the best available published data. The IUCN assessors including three of the authors of the statement totalled the global number at 3, Since then, India, Russia, Bangladesh and Bhutan published the results of their national tiger surveys.
Where a range was stated by the IUCN assessment, the lower end of the range was used for the updated tiger population figure. This brought the total to 3, WWF and the GTF share the concerns of authors of the statement that tiger population data should be based on the best scientific data available.
It is for that reason the estimate was based on the IUCN Red Data listing completed in Goodrich et al, updated with the national tiger survey results from India, Russia, Bangladesh and Bhutan. WWF and the GTF also agreed that the increase in tiger numbers must be balanced with recognition of the severe threats that tigers continue to face.
This was clearly stated in the press release and was the message carried by all credible media. Yes, but only with full action, investment and collaboration from all tiger range countries. At the recent tiger conference in Delhi, governments restated their commitment to the Tx2 goal but this needs to be translated immediately into action on the ground or we will miss the window of opportunity.
Tx2 is still possible but it depends on the speed and scale of government action in the next few months. She says we can ensure the items we buy, such as wood and paper, don't come as a result of illegal logging, which harms tigers. Other countries can learn from the likes of India and Nepal which have seen big increases. That means supporting communities and including them in the conservation efforts.
