Mass tourism for gaur (Bosgaurus) has been currently happening at KhaoPhaeng Ma, Wang Nam Khiao, Nakhon Ratchasima. The effect of mass tourism on gaur and local communities may be overlooked.For example, the effect of emigration of gaurs outside the protected area that may bring human-gaur conflict. The mapping system (aerial map with grid (UTM) system) has been developed as a tool of gaur monitoring to empower local community for participatory gaur management. Other reference points were also added. Basic information of gaur and age / sex identification were also added for guiding observers in data collection. In addition tourists can also use map for ecotourism.
