Habitat comments: "matorral... predominantly evergreen sclerophyllous shrubland... Today the entire area is mainly devoted to recreational activities (e.g. hiking, mountain-biking, picnics, and horse riding), but occasional low-intensity grazing by horses and cattle still occurs. Until 1982 limited farming and firewood extraction took place in lowland areas"
