Sport hunters depleting lion and cougar populations in US and Africa

Washington, June 18 (ANI): A new study has indicated that sport hunters are depleting lion and cougar populations in the United States and Africa.

The study was led by Craig Packer, a University of Minnesota professor and renowned authority on lion behavior, who worked with an international team of conservationists.

The study looked at numbers of lions and cougars killed by hunters over the past 15 to 25 years in Africa and the western United States.

The analysis suggested that management agencies often adjusted quotas to control rather than conserve the big cats in areas where humans or livestock were threatened.

Sport hunting takes a significant toll on these large feline species because replacement males routinely kill their predecessors' cubs to improve their mating opportunities.

The team of scientists confirmed this effect by comparing the impact of hunting on populations of lions, cougars and leopards with its impact on black bear populations because male black bears do not routinely kill infants of other males.

The researchers found that lion and cougar populations have suffered the greatest decline in African countries and US states where sport hunting has been most intense over the past 25 years.

Leopards were not as affected as lions and cougars, most likely because they benefited from reduced numbers of lions.

Black bears, by contrast, appear to be thriving despite the thousands of bears killed by hunters.

The study results point to the need for new approaches to protect humans and livestock and to manage sport hunting without endangering these vulnerable species. ne possibility would be to restrict sport hunting to older males whose offspring have matured.

"We need to develop scientifically-based strategies that benefit hunters, livestock owners and conservationists," Packer said.

"It's important to educate the public about the risks these large predators pose to rural communities and to help hunters and wildlife managers develop methods to sustain healthy populations," he added. (ANI)
