Lake Kaltern contains the largest preserved wetland area between the Po Valley and the main Alpine ridge, which was also included in the European network of "Natura 2002" protected areas. The reed area at the south end of Lake Caldaro is a nature reserve. It is a nesting place for countless and rare birds as well as marsh animals. Scientists have found more than 100 species of birds here. There are, for example, water pipit, reed bunting, bittern, reed warbler, wryneck, Ortolan, linnet, yellow wagtail, long-tailed warbler, tern, black-headed gull, water rail, marsh harrier, hoopoe, tree hawk and many others. This reed area is the only larger habitat of this species between the Reschenpass and Verona and lies at the fork of the main bird flight lines. This is why fish and purple herons, ruffs, snipe, lapwings, black swans, osprey, cranes, cormorants and white storks appear again and again. You can watch the animals from a lookout tower, where most of the birds are described. You can hike through the biotope and admire frogs and amphibians via the nature adventure trail. In the summer of 2010, the nature adventure trail on Lake Kaltern was expanded and extended. Especially recommended for families with children.

Kalterer See Biotopes

Highlight • Natural Monument

Today, Lake Kaltern is heavily influenced by humans: especially on the west and east banks, there are bathing establishments, campsites, restaurants and commercially used areas that lead to a burden on the natural environment. This makes this quiet zone on the south bank all the more important. It is a nature conservation project in which two ponds and bays were built in the reeds. These are intended to provide new habitats and nesting places for water birds and spawning grounds for fish. Source: kalterersee.com/de/highlights/natur-landschaft/der-kalterer-see/biotop

This reed area is the only large habitat of this type between the Reschen Pass and Verona and is located at the fork of the most important bird flight routes. This is why fish and purple herons, ruffs, snipes, lapwings, black terns, ospreys, cranes, cormorants and white storks appear here again and again.
The animals can be observed particularly well from this observation tower, where most of the birds are described. You can walk a bit through the biotope on the nature trail and admire frogs and amphibians.
We even saw a small water turtle here.

In the wet meadows you can observe some birds if you are patient and keep quiet 😉
