[1] Due to its geographical and climatic context - between the Atlantic and Mediterranean - Portugal has a high level of biodiversity on land and at sea.
[7] Remnants of these laurisilva forests are also present in continental Portugal with its few living testimonies Laurus nobilis, Prunus lusitanica, Arbutus unedo, Myrica faya and Rhododendron ponticum.
[14][15] Portugal as a whole is an important stopover for migratory bird species: the southern marshes of the eastern Algarve (Ria Formosa, Castro Marim) and the Lisbon Region (Tagus Estuary, Sado Estuary) hosting various aquatic bird species, the Bonelli's eagle and Egyptian vulture on the northern valleys of the Douro International, the black stork and griffon vulture on the Tagus International, the seabird sanctuaries of the Savage Islands and Berlengas and the highlands of Madeira and São Miguel all represent the great diversity of wild avian species (around 450 in continental Portugal), not only migratory but also endemic (e.g. trocaz pigeon, Azores bullfinch) or exotic (crested myna, pin-tailed whydah).
[19] Due to their isolated location, the volcanic islands of the Azores, Madeira and Salvages, part of Macaronesia, have many endemic species that have evolved independently from their European, African and occasionally American relatives.
[22] while blue whiting, monkfish, Atlantic cod, cephalopods, skates or any other form of seafood are traditionally fished in the local coastal villages.
[29][30] Some protected areas in Portugal other than the ones previously mentioned include: the Serras de Aire e Candeeiros with its limestone formations, paleontological history and great diversity in bats and orchids,[31] the Southwest Alentejo and Vicentine Coast Natural Park with its well preserved, wild coastline.
