Phu Khiao Wildlife Sanctuary

Phu Khiao Wildlife Sanctuary (or written as Phu Khieo; Thai: เขตรักษาพันธุ์สัตว์ป่าภูเขียว) is a wildlife sanctuary in Thailand. It overlaps with three districts of Chaiyaphum province, namely Khon San, Kaset Sombun, and Nong Bua Daeng, covering about 975,000 rai (1,560 km²).

The wildlife sanctuary contains Thung Kamang (ทุ่งกะมัง), an extensive grassland covering an area of approximately 5,000 rai (8.0 km²) at an elevation of 900 m (3,000 ft). It features natural Arundinaria pusilla grassland on the undulated hills alternating with the forest line that make it look like continuous waves with many streams running through it and is surrounded with hill evergreen forest. This grassland is well-known as a breeding ground for endangered wildlife like hog deer, a medium-sized deer that is almost extinct in Thailand. Nowadays, they are distributed throughout the wildlife sanctuary.^[1][2] The surrounding area of Thung Kamang consists of many reservoirs.^[1]
