ON April 10, the World Wildlife Fund (WWF) and Global Tiger Forum (GTF) issued a report stating that the world’s wild tiger population was on the rise, and on track for a doubling in a decade (http://wwf.panda.org/wwf_news/?uNewsID=265197). We do not find this report and its implications scientifically convincing.
1. Having devoted years of our lives to trying to understand and save wild tigers, we believe their conservation should be guided by the best possible science. Using flawed survey methodologies can lead to incorrect conclusions, an illusion of success, and slackening of conservation efforts, when in reality grave concern is called for. Glossing over serious methodological flaws, or weak and incomplete data to generate feel-good “news” is a disservice to conservation because tigers now occupy only 7% of their historic range. A recent World Conservation Union (IUCN) assessment showed 40% habitat loss in the last decade, and a spike in poaching pressure in many regions. Cambodia, Vietnam, Lao PDR and China have virtually lost viable tiger populations in recent years. This is not a time for conservationists to take their eyes off the ball and pat each other on the back.
