WCS is now still working on the site, closely with DNP and KKNP staffs regarding the strengthening of law enforcement through smart patrol system. Moreover, we have expanded our collaborative supports to local communities around KKNP, particularly, strategic informative and technical supports such as tiger and prey monitoring, crocodile survey and conservation, including Human & Elephant Conflict (HEC) mitigation.
