The Miramare Biosphere Reserve and Marine Reserve is situated about 7 kilometres km from the city of Trieste on the Gulf of Trieste close to the Slovenian border. It represents a rocky promontory of karst with coastal cliffs and beaches. Marine habitats of special interest from a conservation perspective are the tidal zone which harbours many endemic species, such as Fucus virsoides, and undisturbed cliffs with a diverse benthic fauna. The aim of the biosphere reserve is to maintain biological diversity in the marine environment surrounding Trieste through scientific research and monitoring activities. Environmental education designed for students and the public is also a major activity in the area.
This small biosphere reserve is not inhabited, however many tourists enjoy underwater tours or visit the castle and garden of the Habsburg family. Both commercial and amateur fishing as well as other recreational activities infringe on the marine habitat.
