The site was identified as important in 2010 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
Chilean Pigeon Patagioenas araucana	LC	resident	2008	abundant	A2
Slender-billed Parakeet Enicognathus leptorhynchus	LC	resident	2008	common	A2
Black-throated Huet-huet Pteroptochos tarnii	LC	resident	2008	present	A2
Ochre-flanked Tapaculo Eugralla paradoxa	LC	resident	2008	present	A2

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2010) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2021) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	likely in short term (within 4 years)	whole area/population (>90%)	very rapid to severe deterioration	very high
Pollution	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Residential and commercial development	likely in short term (within 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90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium

Year	Protected Area	Designation	% overlap with IBA
1988	Cerro Nielol	Monumento Natural	100
