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 60,000 waterfowl, especially geese including the globally threatened lesser white fronted goose Anser erythropus and the 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 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, as well as invasive species. Marshland restoration projects have been carried out while the town of Tata has started establishing rainwater harvesting gardens, with the active involvement of the communities concerned, to keep storm water in place. The Site was significantly extended in 2006 and renamed “Lakes by Tata”, from “Tata, Öreg-tó (Old Lake)”.
