Site description The Ango or Anko Hills lie on the Indo-Myanmar border, in the Ukhrul district, northeast of Manipur. Owing to its remoteness, the area is largely undisturbed. The local community is also inclined to give it some protection. The forests consist of Moist Subtropical and Tropical Evergreen types. The flora and fauna are poorly known, however, the Green Peafowl Pavo muticus and Rufousnecked Hornbill Aceros nipalensis, two threatened species, are reported from this site (A. U. Choudhury pers. comm. 2003).
