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
Copper Pheasant Syrmaticus soemmerringii	NT	resident	2003	present	A3
Mandarin Duck Aix galericulata	LC	breeding	2003	present	A3
Latham's Snipe Gallinago hardwickii	NT	breeding	2003	present	A3
Ashy Minivet Pericrocotus divaricatus	LC	breeding	2003	present	A3
Narcissus Flycatcher Ficedula narcissina	LC	breeding	2003	present	A3
Japanese Accentor Prunella rubida	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%)	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	likely in short term (within 4 years)	small area/few individuals (<10%)	no or imperceptible deterioration	low
Geological events	likely in long term (beyond 4 years)	some of area/population (10-49%)	no or imperceptible deterioration	low
Residential and commercial development	likely in short term (within 4 years)	small area/few individuals (<10%)	no or imperceptible deterioration	low
Transportation and service corridors	likely in short term (within 4 years)	small area/few individuals (<10%)	no or imperceptible 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	Unknown	Very little or no conservation action taking place	low
