Ecology and population study of gaur has been carried out in Khlong Saeng Wildlife Sanctuary, Surat Thani Province during 1994-1995. The result reflected that gaur herds are not roaming only in moist evergreen forest, but also various vegetation types. They feed mostly in natural forest gap, old clearing patches and seasonal draw down areas of Racha Prapha reservior with elevation ranging from 68 to 600 m MSL. Gaur use at least 71 forage plant species from 63 genera from 33 families. Because of good spatial distribution of water sources in this sanctuary, thus, water is not the limiting factors for the population. Mineral lick visiting behavior shows a different pattern of those population of Huai Kha Khaeng WS. They cause damages to 26 species of vegetation which are seperated into 6 categories e.g. rub, stem broken, peel, scar, fall and death. Gaur's dung decay rate is 0.0161 per day (S.D. = 0.00068+-0.0013) at 95 percent Cl. The results from dung density counted from line transect method in two sample sites reflected that population density for Khlong Khuan area is 2.05 animals/square km and 3.30/square km in Huai Thum Chan valley. The average of gaur's herd size is 6.55 (range 2-13, N=7). Causes of threat for this wild cattle are both pouching and interferance mainly from some group of fishermen activities in the reservior nearby gaur feeding sites.
