| Description | South Moravian wetlands with salt marshes are rare biotopes that are significantly threatened by eutrophication, overgrowth, changes in the water regime and water quality. The goal of the LIFE in Salt Marshes project is to reverse these changes in 10 salt marshes in South Moravia. Within aquatic biotopes, the diversity of aquatic invertebrates, algae and cyanobacteria is monitored, as well as physico-chemical parameters, including the water regime. Initial monitoring at the sites showed very high concentrations of chlorides (up to 380 mg/l) and sulfates (up to 3,600 mg/l), which is a typical characteristic of South Moravian salt marshes. Undesirably high concentrations of nutrients, especially ammonium ions detecting municipal waste pollution, and phosphorus were recorded in some localities during the growing season. Eutrophication, in addition to increased saprobity, is also indicated by the presence of mixotrophic taxa (flowerheads, pantheria), bacteria and colorless ciliates. A typical halophyte microflora represented by e.g. filamentous cyanobacteria of the order Oscillatoriales, diatoms of the genera Pinnularia and Gyrosigma was found only at a small number of locations. The initial measurement also points to pesticide pollution in a total concentration of up to 3.44 µg/l. The monitoring of hydrobiological parameters during the implementation of the project will provide valuable data reflecting the success of ecological restoration of sites. |
