Seven sampling sites were selected along the Mekong River in:Cambodia: Mondulkiri and Krong Preah Sihanouk provinces.
These locations represent a gradient of deforestation and human pressure, from highly forested areas with low human densty, to poorly forested areas with high human density. These sampling sites cover from 10*10 up to 15*15 square kilometres. Based on our experience, this spatial scale roughly corresponds to that of rodent populations.
Rodents are sampled in each site during two sessions: one during the dry hot season (February-April) and one during the rainy season (June-September).
