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

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Fischer's Turaco Tauraco fischeri	NT	resident (1999)	present	A1, A3
Eastern Green Tinkerbird Pogoniulus simplex	LC	resident (1999)	present	A3
Mombasa Woodpecker Campethera mombassica	LC	resident (1999)	present	A3
Green-headed Oriole Oriolus chlorocephalus	LC	resident (1999)	present	A3
Chestnut-fronted Helmetshrike Prionops scopifrons	LC	resident (1999)	present	A3
Fischer's Greenbul Phyllastrephus fischeri	LC	resident (1999)	present	A3
Lowland Tiny Greenbul Phyllastrephus debilis	LC	resident (1999)	present	A3
Little Yellow Flycatcher Erythrocercus holochlorus	LC	resident (1999)	present	A3
Black-bellied Starling Notopholia corusca	LC	resident (1999)	present	A3
Spotted Ground-thrush Geokichla guttata	VU	non-breeding (1999)	present	A1
Plain-backed Sunbird Anthreptes reichenowi	NT	resident (1999)	present	A1, A3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1999. The most recent assessment (2023) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	good (>90%)	good (>90%)	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	likely in short term (<4 years)	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high
Climate change and severe weather	happe­ning now	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	high
Agricultural expansion and intensification	happe­ning now	whole of popul­ation/area (>90%)	no or slight decline (<1% over 3 gener­ations)	low
Residential and commercial development	happe­ning now	most of popul­ation/area (50–90%)	no or slight decline (<1% over 3 gener­ations)	low
Biological resource use	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Invasive and other problematic species and genes	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
Natural system modifications	likely in long term (>4 years)	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	A compre­hensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Some limited conservation initiatives are in place	medium
