Tigers can recover given protection, adequate food supplies mongabay.com December 13, 2006 A new study says that if tigers are protected and have sufficient access to abundant prey, their populations can quickly stabilize. The findings have implications for conservation of the world's largest cat species which is fast-disappearing due to habitat loss and poaching for the animal parts trade. Conducted over a nine-year period in India's Nagarahole National Park, the joint Wildlife Conservation Society (WCS) and U.S. Geological Survey (USGS) study found that 23 percent of the park's tigers migrate or are killed each year yet the park's population remains relative stable due to their high reproductive rate of 3-4 cubs per litter born every 2-3 years. The study employed remote camera traps to identify and count individual tigers in the park. "This study shows that even well-protected wild tiger populations have naturally high rates of annual losses, and yet do fine because of their high reproductive rates," said WCS researcher Dr. Ullas Karanth, lead author of the study, which is published in the journal Ecology. "The conservation implications of this study show that effectively protecting reserves to maintain high prey densities is a key pillar in an overall strategy for the conservation of tigers."
According to a study published this summer by the National Fish & Wildlife Foundation, tigers now occupy only 7 percent of their historic range. Further, poaching for a thriving tiger parts market in Western China is putting the species at risk, according to an investigation conducted this summer by the Environmental Investigation Agency. "The good news is that given the chance, tigers can replenish their numbers; the bad news is that they are not being given that chance in many parts of their range," said WCS's noted big-cat researcher Dr. Alan Rabinowitz. In July, WCS launched a new tiger conservation initiative. Known as "Tigers Forever", the program blends a business model with hard science and has already attracted $10 million from venture capitalists. Tigers can recover given protection, adequate food supplies. This article is based on a news release from WCS. Recommend this article?
