Recycling nutrients in fishpond sediment - a key study of fishpond Horusický

Original language description

Periodically flooded ephemeral pools on arable soil are overlooked endangered habitats which serve as refuge for many wetland organisms within mostly homogenous agricultural landscape. In the Czech Republic, these habitats are especially in lowlands critical for the survival of more endangered and protected plant and animal species, which are often bound to open and shallow, early successional stage of aquatic biotopes with unvegetated substrates and without fish. The research of these habitats revealed information about the composition of assemblages and distribution of interesting plants, aquatic invertebrates, amphibians and wetland birds. Especially large branchiopods (Branchiopoda: Anostraca, Notostraca, Spinicaudata) and some waders (Aves: Charadriiformes) are there flagship species, while populations of some of them are the most abundant in field wetlands within the country. Unfortunately, these habitats are very endangered especially by field drainages, filling of field depressions with soil, ploughing absence or using of chemicals. Moreover, it is usually not possible to protect them by site protection, since they are located on arable soil and require very specific management, including conservation of water regime in combination with regular disturbances, such as ploughing. Further research targeted on effective conservation and suitable management of these unique refuges is necessary.
