Tambohorano Wetland NPA This is an IBA in Danger! 


IBA Justification

The site was identified as important in 1999 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):
Species Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Madagascar Teal Anas bernieri EN resident 1998 67 individuals A1, A2, A3, A4i
Madagascar Heron Ardea humbloti EN resident 1998 present A1, A2, A3
Black-banded Plover Charadrius thoracicus VU resident 1998 61 individuals A1, A2, A3, A4i
Madagascar Jacana Actophilornis albinucha EN resident 1998 present A2
Roseate Tern Sterna dougallii LC non-breeding 1998 883 individuals A4i
Lesser Crested Tern Thalasseus bengalensis LC non-breeding 1998 3,200 individuals A4i
Madagascar Fish-eagle Haliaeetus vociferoides CR resident 1998 present A1, A2, A3
Sickle-billed Vanga Falculea palliata LC resident 1998 present A3
Sakalava Weaver Ploceus sakalava LC resident 1998 present A3

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1999).
