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 (2014) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	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	No management planning has taken place	Some limited conservation initiatives are in place	low

Year	Protected Area	Designation	% overlap with IBA
2010	Nonguen	Reserva Nacional	100
2010	Nonguén	National Reserve	100
