Upper River Tejo


Year of compilation: 2002

Site description
Steep valleys with cliffs and Mediterranean scrub, located at the eastern border of central Portugal. The riverbed is much wider than it was 25 years ago, due to the construction of a large dam, and now allows the small-boat traffic of professional fishermen and recreational purposes.This site includes a great diversity of habitats that hold a wide mediterranean animal and vegetal diversity.



Key biodiversity
This area has a great value due to its wide diversity of species, withh special importance of cliff-nesting species and some steppic birds in plain areas. This site holds the greates population in Portugal of ciconia nigra and a significative proportion of large raptors. Also it is the only place in Portugal with breeding Aegypius monachus and still it is possible to found a Pterocles alchata.



Pressure/threats to key biodiversity
Important cliff-nesting species are disturbed by boating and fishing activity in the reservoirs along the cliffs. In recent years several forest plantations (Eucalyptus) and special hunting areas have been established along the edge of the site, which have affected birds. In particular, there have been attempts in the hunting areas to control predators, including large raptors (`Other' threat).
