Lake Neusiedl (, ; or ; ; ; ) or Lake Fertő (), is the largest endorheic lake in Central Europe, straddling Austria and Hungary. The lake is saline and covers , of which is on the Austrian side and on the Hungarian side. Its drainage basin is about , about three times its size excluding the lake itself. From north to south, the lake is about long, and it is between and wide from east to west. On average, its surface is above the Adriatic Sea and it is no more than deep.

The surrounding landscape has been occupied since about 6000 BC, and the towns and villages around the lake have been trading and meeting points for local people and wider cultures for centuries. Given its cultural importance and the often handed-down, rustic architecture of the villages, Lake Neusiedl and environs is inscribed on the UNESCO World Heritage List since 2001.

Before the regulation works of the 19th century, the lake reached in the southeast to the marshlands of the Hanság () which have been increasingly drained and claimed for agriculture from the 16th century onward. Originally, the lake was thus closely connected to the Danube and the Rába river systems.

Nature and wildlife

Most of the lake is surrounded by reeds, a habitat for wildlife (making the lake an important resting place for migratory birds). Reeds are harvested in winter as soon as the ice is solid enough. This serves its ecology (removal of the bulk of organic matter that would otherwise decay in the lake) and the local economy (the reed is sold for various purposes, mostly related to construction and housing). During the summer months, there are occasional reed fires, as dry reed is easily flammable; these often spread quickly as it tends to be windy. Water quality is determined by temperature, wind, and by the amount of salt and mud emanating with the ground water from the sediments.

Several plans for dams and other intrusive construction works for economic growth/sustainable energy directly threatened its endemic biotopes (rather uniform and rare still, brackish water and temperate climate habitats for hundreds of species) were mooted during the first half of the 20th century. A drainage scheme to recover much land which would be reasonably fertile soil as well as intensive aquaculture had been finalized and approved in 1918. This was aborted when most of the lake became Austrian territory after World War I ended that year. In 1971 plans for a bridge across the Austrian part of the lake were thwarted by environmentalists.

In 1993 the National Park Neusiedler See-Seewinkel gained international acceptance as an IUCN Category II preserve. In 2001 the national parks in Austria and Fertő-Hanság in Hungary were together accepted as a World Heritage Site. Lake Neusiedl See and its surrounding areas in Austria also enjoy protection through the Ramsar Convention on Wetlands.

Mammals

Over 40 mammal species have been recorded from the area, including the European ground squirrel, the steppe polecat and the European hamster.

Birds

In the area over 300 bird species have been recorded with the earliest studies made by the Hungarian naturalist István Fászl. Of these, around 150 breed, representing around 40% of the European and 80% of all Austrian bird species. The area contains one of the largest breeding populations of great egrets, with up to 700 pairs. There are also around 35 pairs of grey heron and 70 pairs of great bustard. One of the best known bird species in the area is the white stork, which is seen as a symbol of the region. Other species present include Eurasian spoonbill, purple heron, eastern imperial eagle, white-tailed eagle, greylag goose, golden oriole, European bee-eater, pied avocet, ruff, Kentish plover, common tern, common redshank, black-tailed godwit, Eurasian curlew, western yellow wagtail, short-eared owl, Montagu's harrier, bittern and many others which are of interest to local and visiting birdwatchers.

Fish

Native fish species include the pike, zander, European carp and wels catfish, alongside numerous minnows, such as stickleback, common bleak, white bream, common bream and ruffe. The European eel is not native to the lake, but was introduced as a food source for humans. Due to environmental concerns, further releases of young eels has been banned. Prussian carp has also been introduced, alongside the pumpkinseed.

Amphibians

The European tree frog is a common species in the area. Other amphibians that can be found, especially in the reed belt and the lakeside edge, include common toad, European green toad, common spadefoot, moor frog, agile frog, pool frog, marsh frog, edible frog and the European fire-bellied toad. Danube crested newt and smooth newt are also present.

Reptiles

Reptiles are represented by the grass snake and a number of lizard species including the European green lizard, sand lizard and the common lizard. Occasionally, dice snakes may be seen, but the meadow viper, which was previously identified around the lake, has not been seen since 1973.

Towns and villages around the lake

Traces of human settlement around Lake Neusiedl go back to the Neolithic period. The area became densely populated from the 7th century BC onward, initially by people of the Hallstatt culture and remained so throughout Roman times. In 454 Theodoric the Great, the preeminent king of the Ostrogoths, was born here. Near Fertőrákos there are two Roman villas and a 3rd-century Mithras temple open to visitors.

The more important extant towns lying on the lake's shore are Illmitz (Illmic), Podersdorf am See (Pátfalu), Weiden (Védeny), Neusiedl am See (Nezsider), Jois (Nyulas), Winden (Sásony), Breitenbrunn (Fertőszéleskút), Purbach am Neusiedlersee (Feketeváros), Donnerskirchen (Fertőfehéregyháza), Oggau (Oka), Rust (Ruszt) and Mörbisch (Fertőmeggyes) in Austria, and Sopron, Fertőrákos, Fertőboz, Fertőd, Balf and Fertőújlak in Hungary, with the communities of Illmitz, Apetlon (Mosonbánfalva) and Podersdorf am See forming the so-called Seewinkel (lake corner), which is located between the lake and the Hungarian border. Hungarian names of Austrian towns lying on the lake's shore are given in parentheses.

Tourism

Despite remaining a protected wildlife habitat, the region of Lake Neusiedl, particularly in its Austrian part, draws significant numbers of tourists. The lake is known as the "Sea of the Viennese", as it offers ample opportunities for sailing and windsurfing at a reasonable distance from Vienna. There is also some commercial fishing.

Low water levels at times cause sailing and fishing boats to run aground much more frequently and many moorings suffer. However, they somewhat help the annual freestyle mass crossing, by foot, from Mörbisch to Illmitz. Everybody who can swim and is more than in height can participate in this event, which was revived in 2004.
