The type forests are made up of laurel-leaved evergreen hardwood trees, reaching up to 40 m in height when older. Many of the species are endemic to islands, and harbour a rich biota of understorey plants, invertebrates, some species of lizards ("Lacerta lepida", "Podarcis bocagei", "Chalcides striatus"), slowworms ("Anguis fragilis"), and snakes, ("Elaphe scalaris", "Coronella girondica", "Natrix maura"). The island has some goats and wild boars ("Sus scrofa"), wild horses lived there until recently ("Crocidura russula", "Erinaceus europaeus", "Talpa occidentalis"), bats ("Pipistrellus pipistrellus", "Eptesicus serotinus", "Rhinolophus ferrumequinum"), feral cats ("Felix catus"), feral mink ("Mustela vison"), rabbits, mice, rats and birds such as Iberian chiffchaff, the coal tit, the great tit, woodpecker, Eurasian wryneck, collared dove, common wood pigeon, blackbird, "Scolopax rusticola", greenfinch, warbler, finch, saithe, stonechat, robin, goldfinch, wagtail, black redstart, buzzard, goshawk, and peregrine falcon. Besides many seabirds species such as cormorants and shorebirds take refuge on the island and several species of gulls nest in the breeding season.
