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 (2005) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Transportation and service corridors	happening now	small area/few individuals (<10%)	very rapid to severe 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

Year	Protected Area	Designation	% overlap with IBA
1995	Vale do Guadiana	Parque Natural	91
1997	Guadiana	Site of Community Importance (Habitats Directive)	23
1999	Vale do Guadiana	Special Protection Area (Birds Directive)	100
2012	Ribeira do Vascão	Ramsar Site, Wetland of International Importance	2
