Thailand has the most extensive protected area system in the region, encompassing 60 percent of its remnant wildernesses and 15 percent of the total land area. Unfortunately, many of these habitats are fragmented, which has jeopardized the wildlife populations that reside here. Furthermore, wildlife within protected areas is still threatened by poaching for commercial sale. Cattle herds are also increasingly ranging freely inside protected areas, causing competition with native ungulates. All these pressures pose a particular danger to the long-term viability of tigers and many other threatened species.
