Lake Naplas

With its 150 hectares, the area of the lake Naplas is the second biggest natural protected area in Budapest. It has four main parts: the lower swamp, the lake, the upper swamp and the Cinkota forest. The area consists of wide variety of biotops so many species of insects, reptiles, birds, and amphybians are able to find their habitats there. The lake is also very popular among local people, it is used as a fishing pond in summer and as an ice court in winter.

A small forest of willow and alder trees determines the landscape on the lower swamp. The most valuable plants are autumn crocus (Colchicum autumnale), iris (IIris sibirica), orchid (Dactylorhiza incarnata), and a clematis (Clematis integrifolia). Nightingale, robin, cuckoo and golden oriole net in the forest, and many pheasant can use the bushes as hiding-place.

The lake Naplas is situated in the centre of the area. The water surface is only 16 hectares, but it is the biggest lake of Budapest. The lake was made as an artificial water-basin of the stream Szilas in the early seventies (Originally there were a swamp). The deepest part bordered by reed is situated at the dam and becomes less and less deep towards the eastern part. The reed and the clear water surface attracts lots of birds during the whole year. Most of them are black-headed gulls and mallards, but moorhens (Gallinula chloropus) and little bitterns (Ixobrychus minutus) are able to find their net sites as well.

The most intact part of the protected area is the old forest on the upper swamp. The old crack willow trees (Salix fragilis) are the most typical ones on the flood plain. There are almost impenetrable rushes mixed with stinging nettle on the clearings and grass meadow on the dryer upper parts. The stream is bordered by elderberry (Sambucus nigra) bushes which provide with food and hiding place for migratory birds.

The Cinkota forest is situated on the hill above the lake. It has an older part of English oak (Quercus robur) forest. There are also can be found introduced trees as black locust, European black pine, red oak, and native plants as blind nettle, stinging nettle, greater celandine in the grass. Many protected birds have nets in the forest, among them the black woodpecker (Dryocopus martius) is the rarest.
