Site description Kuarbari or Koabari is a small marshy area near Dhakuakhana township in Lakhimpur district, eastern Assam. Surrounded by villages with cultivation, this site attracts a large number of waterfowl including Spot-billed Pelican Pelecanus philippensis, Greater Leptoptilos dubius and Lesser L. javanicus Adjutants and Asian Openbill Anastomus oscitans (Choudhury 2000). The villagers in the area are highly motivated to protect the area and there is virtually no hunting, although poisoning was regular in the past. Dalani means swamp. Dal is a kind of aquatic grass. This wetland IBA has the usual short grasses on the fringe. Bamboos and tall trees are found in the surrounding villages.

Key Biodiversity 

AVIFAUNA: Detailed study on this site has been conducted since 1989. Due to the protection by villagers, quite a large number of waterfowl are found here, although the site still does not qualify in A4iii criteria (= 20,000 waterbirds). This site has been selected purely on the basis of regular and significant numbers of the adjutant storks found here. Critically Endangered Oriental White-backed Vultures Gyps benghalensis and Slender-billed vultures G. tenuirostris are also seen, but they are widespread, move around a lot and are found in numerous other areas.

OTHER KEY FAUNA: As the wetland is surrounded by human habitation, not many wild mammals are found in the site.
