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.
This small biosphere reserve (290 hectares) is not inhabited, however many tourists enjoy underwater tours or visit the castle and garden of the Habsburg family.
The area is managed by the Italian World Wildlife Fund on behalf of Italy’s Ministry of the Environment and Protection of the Territory.
Major habitats and land cover include Zostera marina and Cymodocea nodosa meadows, a tidal zone with endemic species such as Fucus virsoides, and Mediterranean sclerophyllous vegetation on terrestrial part.
