Site description This site covers parts of Cachar and Hailakandi districts in southern Assam, bordering Mizoram and Manipur. The Innerline Reserve Forest (RF) is the largest RF in Assam, with an area of more than 110,000 ha. Katakhal and Barak RFs are contiguous with Innerline. The area is mainly composed of low hills that are the northern promontories of the Lushai or Mizo Hills. Small patches of plain area found between the hills are mostly under human habitation. Dhaleswari, Barak and Sonai are the main rivers. These reserve forests, along with some other adjacent reserve forests, were proposed as Dhaleswari Wildlife Sanctuary in the early 1980s. The area has a rich diversity of mammals and birds (Choudhury 1983). Part of Katakhal RF has been ornithologically surveyed as far back as the 19th century (Inglis 1896-1910). The forests are mainly Tropical Wet Evergreen and Tropical Semievergreen. The two characteristic tree species of the area are Dipterocarpus turbinatus and Palaquium polyanthum. There are vast and continuous stretches of bamboo with cane and reeds. There are some small but excellent patches of tropical rain forest on the plains in the Innerline RF.
