  General Description   Iroise Biosphere Reserve, located on the coast of Brittany, comprises small rocky marine islands and islets and open marine areas to a depth of -20 meters with strong currents and a high tidal range. It is of significance from a biodiversity point of view since it encompasses a variety of habitats e.g. for more than 300 species of seaweed, large sea bird colonies and populations of basking shark (Cetorhinus maximus) and grey seal (Halichoerus grypus). The Isle of Ouessant reaches no higher than 60 meters in altitude and its landscape is one of meadows grazed by sheep and crisscrossed with stone walls and numerous hamlets.
The transition area of the biosphere reserve includes the islands of Ouessant and Molène with their 1,200 inhabitants (2001). With about 300,000 passengers on marine and air transports annually (2001), daily tourism is a significant element of the local economy, providing the basis for commercial activities on the islands. However, also fishing activities remain important. Numerous educational and training activities are carried out in the biosphere reserve, such as guided visits for school classes, exhibits, public information meetings and internships.
