There are extensive areas of cork oak and Pyrenean oak. Holm oak is found on xeric sites. Sweet chestnut grows at higher elevations.

There are also large areas of olive, Maritime pine, and Eucalyptus plantations. Within the area you can find the European otter, Cabrera’s vole and, mainly in the north, the Iberian lynx. The Iberian wolf also lives in the area in small numbers.
