Upper River Douro and Águeda valleys

Year of compilation: 2002

Site description
The central area of the site is constituted by little plateaus cross-cut by river valleis that run up to river Douro, where abound marshes rounded by hedgerows, crop-lands, vineyards, etc...Shrublands of cistus, genistas and holm oak are also important and forest of oaks and cork trees.

Key biodiversity
The cliffs provide exceptionally good breeding habitat for raptors and other soaring birds that feed in near plateaus where agricultural and cattle breeding activities are developed. Is also important for mediterranean and pseudo-steppic birds.

Pressure/threats to key biodiversity
The area is almost undisturbed by human activities, although important cliff-nesting species are sometimes disturbed by boating and fishing in the reservoirs along the cliffs. The ongoing abandonment of cultivation and sheep-raising will reduce the food resources currently available for the large raptors.
