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
Nilgiri Woodpigeon Columba elphinstonii	VU	resident	2004	present	A1, A2
Rufous-throated Wren-babbler Spelaeornis caudatus	LC	resident	2004	present	A2
Nilgiri Chilappan Montecincla cachinnans	NT	resident	2004	present	A1, A2
Nilgiri Flycatcher Eumyias albicaudatus	LC	resident	2004	present	A2
Nilgiri Sholakili Sholicola major	NT	resident	2004	present	A1, A2
Black-and-orange Flycatcher Ficedula nigrorufa	LC	resident	2004	present	A2
Crimson-backed Sunbird Leptocoma minima	LC	resident	2004	present	A2
Nilgiri Pipit Anthus nilghiriensis	VU	resident	2004	present	A2

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 (2003) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	slow but significant deterioration	high
Natural system modifications	happening now	whole area/population (>90%)	slow but significant deterioration	high
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed
