Site description (2002 baseline):
Site location and context
A flat basin bordered by hills, drained by the Luznice river, and containing a unique system of c.500 fish-ponds connected by a network of drains, canals and artificial streams. Many of the ponds support littoral vegetation, and there are remnants of wet meadows and
Alnus riverine forest bordering the shores and watercourses. The region is an important source of gravel, sand and peat, and is highly suitable for recreation and tourism. This area includes three areas that were treated as subsites in the previous The Tøeboòsko IBA covers a part of the Tøeboòsko plateau between the cities of Veselí nad Lunicí and Èeské Velenice in the south-eastern part of Southern Bohemia on the border with Austria. The area has changed dramatically since the Middle Ages. The forests were logged, land drained and a complex of more than 500 fishponds of various sizes connected by a network of drains, canals and artificial streams (Nová øeka river, Zlatá stoka - Golden Canal) was created. Different types of biotopes of shallow ponds have since evolved at the original locations of primeval floodplain forests and wetlands, reaching a secondary ecological equilibrium. Other large wetlands lie in the floodplains of the Lunice and Nová øeka rivers. The numerous peatbogs are considered to be the most valuable ecosystems of Tøeboòsko. They originated during the last glaciation at sites with favourable conditions and limited permeability of the base. The prevailing types of forests are pine forests with spruce or oak; floodplain oakwoods and wetland alderwoods dominate the floodplains. Stands of Swiss Mountain Pine (Pinus rotundata) in peatbogs are also considered valuable.
The Trebon region is one of the most important areas for waterbirds in central Europe, with 10,000-20,000 individuals visiting the fish-ponds on autumn migration. More than 150 species nest within the IBA, including a variety of raptors, woodpeckers and forest passerines. Breeding species of global conservation concern that do not meet IBA criteria:
Crex crex (7-15 pairs).
Pressure/threats to key biodiversity
Fishery practices, including manuring and manipulation of water-levels, present a particular threat. Hunting, intensive pig-breeding and the generally unfavourable state of farmland pose additional problems.
About 89% of this IBA is covered by the Tøeboòsko Protected landscape Area and Biosphere Reserve, almost 18% belongs to a Ramsar site and there are 27 small-scale protected areas. IBA covers SPA Trebonsko (47,360 ha)
