Brittany's contrasting landscapes give shelter to a remarquable biodiversity. Its 2370 km long shoreline facing the  Atlantic ocean is a meeting place for many species that don't normally encounter.  It is also a refuge for numerous endangered species. Tidal reservoirs and marshes bear a particularly rich ornithologic fauna, and the wild inland regions, like the Monts d'Arrée, are equally favorable for rare floral species.

The flora
The Islands are particularly appreciated by certain species: the sea-daffodil, normally rather to be found in meditarranian areas, chose the breton island Houat for a host. The delicat Glenan narcissus, that grows in no other place than on the Glenan archipelago, owes its survival to the sole mobilisation of  the « Bretagne Vivante »organisation, and the National Botanic Conservatory in Brest. There are many more, like the pretty « Crozonnaise bleue du Finistère ». Sea holly prefers to bury its roots deeply into the sand to defeat the stormy winds. Insectivorous plantes, like sundew, can be found in the peat bogs of the Monts d'Arrée. Hanging on to the cliffside, like sea-thrift (Armeria maritima) and campion (silene), or hidden away in stone-hollows like rock samphire, some plants have chosen most inhospitable places to proudly hold up their delicate colours against the roughness of the elements.

Fauna
Sometimes sedentary, but mostly migrating, the species that inhabit the armoric peninsula are great explorers, some of them even go as far as to the limits of the Arctic Circle. First region in France for seabird breeding, Brittany is a paradise for bird-enthousiasts. With a little discretion, you can observe various species, like the Great Cormorant, the Nothern Gannet, Puffins, Choughs and many others.

Even if 25 different species of marine mammals have been located in Brittany over the last 20 years, most of them don't stay long. Only the grey seal, earless seal and bottlenose dolphin, who give regular signs of life in the bay of the Mont Saint Michel, as well as in the surroundings of the île of Sein and the Molène archipelago, are living near the breton coasts all through the year. Some rare humpback whales, few orcas and sperm whales come venturing here, but they quickly leave   searching for waters that would better suit their needs. Certain semi-aquatic mammals, like otters or beavers, like breton streams and rivers. But the European mink, an endangered species, is seriously rivalled by its American cousin. About fifty species of  various terrestrial mammals have been registered in Brittany, among which several protected species of bats.
