While many thought the big cats require reserves away from human activity, a new analysis of camera trap data from Chitwan National Park in Nepal reveals humans and tigers can coexist by occupying the forest at different times of day. The findings reported in the Proceedings of the National Academy of Sciences may open up new opportunities to protect the endangered animals in the face of mounting population pressure from nearby settlements. Known for being shy and elusive, tigers are thought to avoid populated areas where they would have to compete with humans for space and resources. To test this notion, researchers set up camera traps in and around Chitwan to assess tiger, prey, and human activity in the shared use forests surrounding the park compared to more secluded areas. Chitwan is a premier tiger reserve at the base of the Himalayas. But the surrounding area also supports more than 200,000 people. Nearby residents frequent the jungle to gather firewood and food for livestock. The photos, collected over two years, show that tigers did not avoid areas frequented by humans, but instead laid low in daytime hours during peak human activity. While a fifth of all tiger sightings within the park happened during the day, only five percent of sightings outside the park occurred in daylight. The switch to a more nocturnal schedule allowed humans and tigers to share the same space at different times. While further research is necessary to determine the factors contributing to coexistence, the findings suggest good conservation may go beyond mere zoning. At the very least it forces conservationists and policy makers to rethink some of the basic premises of conservation models, says study author Neil Carter of Michigan State University. This kind of opens the door a little bit. There might be a possibility to have these animals coexist even in 1/5

2 areas where there are people and human activities. With 80 percent of the tigers range occurring outside of protected areas in mixed-use forests, that s good news. Smart measures like restrictions on nighttime driving and better overnight security for livestock could ensure residents coexist peacefully with these endangered beasts.

Robin says: September 5, 2012 at 7:27 am This makes sense considering how large predators are increasingly coexisting with people in the American West, including mountain lions. It seems to me that many large animals can and will adapt to living amongst humans, even large numbers of humans, if we humans will simply allow them to (ie, don t shoot them on sight).
