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
Giant Coua Coua gigas	LC	resident	1996	present	A3
Running Coua Coua cursor	LC	resident	1996	present	A2, A3
Olive-capped Coua Coua olivaceiceps	LC	resident	1996	present	A3
Archbold's Newtonia Newtonia archboldi	LC	resident	1996	present	A2, A3
Lafresnaye's Vanga Xenopirostris xenopirostris	NT	resident	1996	present	A2, A3
Sickle-billed Vanga Falculea palliata	LC	resident	1996	present	A3
Thamnornis Thamnornis chloropetoides	LC	resident	1996	present	A2, A3
Sakalava Weaver Ploceus sakalava	LC	resident	1996	present	A3

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