Lacken, Burgenland, about 40 small, up to 3 km long, 1 km wide and 0.5 m deep lakes or pools in the Seewinkel area in Burgenland (east of Lake Neusiedl). The largest lakes are Lake Zicksee (Zicklacke) and Lake Lange Lacke. The smaller lakes dry out in summer, which favours the development of salt crystals and halophytes typical of the area. Like the shores of Lake Neusiedl, Lacken are the habitat for more than 250 species of birds. In 1993 Austria and Hungary founded the Lake Neusiedl - Seewinkel national park. Most of the Lacken (except Lake Zicksee) are part of the conservation area of the national park.
