In 2006, Ecuadorian conservationist Santiago Espinosa received a Russell E. Train Fellowship from WWF’s Education for Nature Program (EFN) to conduct research in wildlife ecology. Santiago’s research involved spending long periods of time in the Amazonian rainforest. He captured photos that highlight the spectacular wildlife that lives in Yasuní National Park.

WWF caught this tiger on camera in Malaysia. While a "camera trap" might sound menacing, it actually does not harm wildlife. The name is derived from the manner in which it "captures" wildlife on film.

Camera traps are not the intricate and elaborate devices you might imagine. These innovative conservation tools are in fact nothing more than everyday cameras, armed with infrared sensors that take a picture whenever they sense movement in the forest.

On the Indonesian island of Sumatra, WWF collaborates with the Riau Forestry Department to use camera traps to help determine which species are present and absent from the region.

A July 2012 camera trap study in Nepal identified 37 individual tigers—a marked increase from 18 tigers counted in 2009. The tigers were monitored over a three-month period inside Bardia National Park in Nepal and the Khata wildlife corridor in the Terai Arc Landscape.
