The site was identified as important in 2002 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
Dark-backed Imperial-pigeon Ducula lacernulata	LC	resident	2000	present	A2
Wallace's Scops-owl Otus silvicola	LC	resident	2000	present	A2
Sumba Cicadabird Edolisoma dohertyi	LC	resident	2000	present	A2
Brown-capped Fantail Rhipidura diluta	LC	resident	2000	present	A2
Flores Monarch Symposiachrus sacerdotum	EN	resident	2004	present	A1, A2
Flores Crow Corvus florensis	EN	resident	2004	present	A1, A2
Yellow-spectacled White-eye Heleia wallacei	LC	resident	2000	present	A2
Thick-billed White-eye Heleia crassirostris	LC	resident	2000	present	A2
Golden-rumped Flowerpecker Dicaeum annae	LC	resident	2000	present	A2
Flame-breasted Sunbird Cinnyris solaris	LC	resident	2000	present	A2

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2002).

State (condition of the trigger species' habitats)
Habitat	Habitat detail	Reference area (ha)	Actual area (ha)	Habitat quantity (% remaining)	Habitat quality (carrying capacity)	Result
Forest		5500	5500	-	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1	Threat level 2	Timing	Scope	Severity	Result
Agricultural expansion and intensification	annual & perennial non-timber crops - small-holder farming	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Invasive and other problematic species and genes	invasive non-native/alien species/diseases - named species	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Transportation and service corridors	roads and railroads	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation	Management planning	Other conservation action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	The conservation measures needed for the site are being comprehensively and effectively implemented	high
