The Site comprises a portion of the Lake Fertö alkaline steppe and the Herlakni and Oberlakni lake areas. Both sectors support extensive reedbeds, saline grassland, marshland and open waters. The area is important for the breeding, wintering and staging of several species of internationally endangered waterbirds such as lesser white-fronted goose (Anser erythropus) and red-breasted goose (Branta ruficollis). The Site also supports endemic plant and invertebrate species which are important for maintaining the biological diversity of the Pannonic biogeographic region. The lake plays an important role in sediment trapping and climate modification but is in a state of advanced eutrophication. Human activities include traditional fishing, reed harvesting and recreation. There are two visitor centers, nature trails and bird watching towers. In the surrounding area outstanding castles and classical Roman era sites such as a temple to Mithras give a particular cultural value to the Site.
