MONDULKIRI, CAMBODIA - 2002/05/01: Here, Pnong man Ply Ch'hroeut helps to measure one of his resin trees along with Pet Paktra of the Wildlife Conservation Society. The WCS wants to deliniate a conservation area that would protect the Pnong resin trees and the surrounding wildlife. Deep in the forests of eastern Cambodia, the Pnong people live hours from roads and other towns, and far from the lifestyles of the rest of the world..
