Description
Considerable contingent of endemic species with a western centre of gravity in an environment where there is still an optimal balance between silvo-pastoral activities and naturalistic values.
Area of international interest for the transit of many medium- and long-range migratory species in late summer and autumn (post-reproductive migration).
Habitats of special interest not included in Annex I of Directive 92/43/EEC are present: underwater environments with Hymenolubius and Saxifraga arachnoidea (1%).
