Camera traps: a window into a hidden world
It costs $35 a day for a survey team to place and maintain camera traps
Camera traps use infra-red to detect animals moving in front of the lens, then take photographs without disturbing wildlife. Species that are hard to observe in the wild because they are shy or active at night can be observed, and important data on their presence, distribution, and population can be estimated. For many species, especially rare species occurring at low density, camera traps are sometimes the only way to find out this information, which is then used to inform protected area management and conservation interventions. WCS Cambodia has published more than 20,000 camera trap records, allowing researchers from all over the world to use the data to improve conservation actions.
