Located near the Duna River by the border with Slovakia, the Site is composed of a mosaic of habitats including meadows, pastures, spring bogs, remnants of former extensive fen and bog areas, reedbeds, agricultural land, fishponds, streams and a lake. Öreg-tó (“old lake”), an artificial lake created in the centre of the town of Tata during the middle ages, collects water from the Által-ér stream and is important for maintaining the biological diversity of the region. The Site is an important habitat for migratory birds, supporting up to 80,000 waterfowl, especially geese, and supports the globally threatened lesser white fronted goose Anser erythropus and red-breasted goose Branta ruficollis. It is wedged between urban and industrial regions as well as the agglomeration of Tata. Human activities are concentrated around agriculture and fishing. A number of educational activities and excursions are organized on the Site, and an annual wild geese festival takes place in the town. The main threats to the ecological character of the Site are organic and oil pollution of the streams and creeks that flow into the lake, and the expansion of private land ownership and building activities in the surrounding area. Marshland restoration projects have been carried out. Local restrictions on hunting help to preserve the natural values of the Site. The Site was significantly extended in 2006 and renamed “Lakes by Tata”, from “Tata, Öreg-tó (Old Lake)”.
