Wildlife Conservation Society uncovers record number of jaguars in Bolivia
Date:10/19/2011

In a new camera trap survey in the world's most biologically diverse landscape, researchers for the Wildlife Conservation Society have identified more individual jaguars than ever before.

Using technology first adapted to identify tigers by stripe patterns, WCS conservationists have identified 19 individual jaguars by spot patterns in the rainforests of Bolivia, a record number for a single camera trap survey in the country. The animals were identified from a total of 975 photographs, a record number of images due to the use of digital cameras as opposed to camera traps that use film.

The images come from the Alto Madidi and Alto Heath, a region at the headwaters of the Madidi and Heath Rivers inside Bolivia's outstanding Madidi National Park. The survey also included Ixiamas Municipal Reserve, created following a previous WCS survey in 2004 along the Madidi River, which revealed a high abundance of jaguars and other species such as white-lipped peccaries, spider monkeys, and giant otters.

"We're excited about the prospect of using these images to find out more about this elusive cat and its ecological needs," said WCS Conservationist Dr. Robert Wallace. "The data gleaned from these images provide insights into the lives of individual jaguars and will help us generate a density estimate for the area."

The study is noteworthy in its use of digital camera traps replacing the traditional film units used in the past. The cameras are strategically placed along pathways in the forest and especially the beaches of rivers and streams for weeks at a time, snapping pictures of animals that cross an infrared beam. Now, researchers returning to the traps can download the images in seconds, rather than waiting days for film to develop. Before embarking on second field trip to the even more remote Heath River, Bolivian jaguar field biologist Guido Ayala noted that "series of digital images also capture more data than traditional film."'/>"/>
