1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2002) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2002. The most recent assessment (2014) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high

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	Not assessed	Not assessed	low

Year	Protected Area	Designation	% overlap with IBA
1990	Rios Sabor e Maçãs	Special Protection Area (Birds Directive)	93
1997	Rios Sabor e Maçãs	Site of Community Importance (Habitats Directive)	62
1998	Minas de St. Adrião	Site of Community Importance (Habitats Directive)	<1
