The site was identified as important in 2004 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 List1	Season	Year(s)	Size	IBA criteria
Grey-faced Buzzard Butastur indicus	LC	breeding	2003	present	A3
Japanese Paradise-flycatcher Terpsiphone atrocaudata	LC	breeding	2003	present	A3
Japanese Robin Larvivora akahige	LC	breeding	2003	present	A3
Japanese Accentor Prunella rubida	LC	breeding	2003	present	A3
Yellow Bunting Emberiza sulphurata	LC	breeding	2003	present	A3
Grey Bunting Emberiza variabilis	LC	breeding	2003	present	A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2015) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	good (> 90%)	poor (40-69%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Energy production and mining	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Geological events	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Human intrusions and disturbance	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Pollution	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Transportation and service corridors	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>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
