River Guadiana

Year of compilation: 2000

Site description
This recently designated Natural Park includes a stretch of the lower Guadiana valley and the surrounding areas, close to the south-east border of Portugal. The valley is steep, with cliffs and sclerophyllous scrub. In the remaining areas there are mainly steppic habitats, non-intensive cereal fields and scrub.

Key biodiversity
An important area for breeding raptors, especially cliff-nesting species, but with good numbers of some birds of steppic habitats and of wetlands as well. Significant proportion (³1%) of national population breeding at site: Circaetus gallicus (1-5 pairs).

Pressure/threats to key biodiversity
Ongoing abandonment of agriculture will lead to an increase in the extent of scrub and a reduction in extent of steppic habitats, reducing densities of open-country bird species. There are plans to build a dam downriver, which will partially flood the area, and another large reservoir is planned upstream, which will affect water-flow through the site.

Protected areas
National High International Partial69,733 ha of IBA covered by Natural Park (Guadiana, 69,733 ha). IBA overlaps with Special Protection Area.
