Scientists are using unattended cameras to record evidence of rich wildlife diversity in the Cambodian jungle, which until recently had been off-limits to scientists during three decades of civil war. This effort — the first of 10 planned by the Cambodian Wildlife Protection Office working with the World Wildlife Fund and Wildlife Conservation Society — photographed 14 mammal species, including two kinds of leopards, wild dogs, sun bears, and wild pigs. But scientists are troubled that there were no signs of endangered tigers, elephants, or banteng, a large species of wild cattle, and fear theses species are being hunted by poachers.
