The tiger is one of the most visible icons of conservation in India, and massive investments have been made for its conservation for over five decades. While there have been a few, well-documented success stories at the scale of individual reserves, there have been no concerted efforts to assess the efficacy of long term conservation programs at large regional scales (> 10,000 sq km). In a recent paper titled “Tigers against the odds: Applying macro-ecology to species recovery”, published … Read More
A Flawed Vision — Demystifying India’s Tiger Counts
This article was originally published in The Telegraph.
For some reason, reports on India’s ‘tiger numbers’ get a lot of people excited. This was the case on July 28, 2020 when a report on the country’s tiger numbers from 2018 was released accompanied by profuse self-laudatory statements. The fact is there is nothing new in this report because the same results were released by the prime minister a year earlier. Perhaps everyone was bedazzled by the beautiful tiger photos and … Read More
Statement of Concern by Tiger Biologists on the WWF-GTF Report
On Sunday, April 10th, 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. We do not find this report1 and its implications scientifically convincing.
- 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
Man-eaters — When Caring Less May Actually Help
Conservationists should be concerned about saving the species, rather than every individual tiger.
The shooting of a man-eating tiger, as it happened recently in the Nilgiris, Tamil Nadu — barely two weeks after two other tigers preyed on four people in neighbouring Karnataka — invariably polarises public opinion. Locals, whose lives are at risk, want maneaters shot. Animal lovers, on the other hand, demand their “safe capture.” Caught in the middle, officials have to confront increasingly angry mobs, while authorities … Read More
Counting Tigers Reliably — Combining Information From Multiple Sources
Authors Arjun M. Gopalaswamy, K. Ullas Karanth, Andy Royle, Mohan Delampady, James D. Nichols and David W. Macdonald demonstrate innovative approaches that integrate information from photographic capture-recapture and genetic data to derive more robust estimates of tiger densities in Bandipur Tiger Reserve, India. These are the highlights of their study published in the journal Ecology in 2012.
In landscapes where wildlife occurs in low densities, gathering information from a single method often does not allow accurate estimation of population densities … Read More
