Create ponds for amphibians
A before-and-after study in 1990–1992 of a man-made pond within woodland on the constructed Danube Island, Austria (Chovanec 1994) found that at least six amphibian species reproduced in the pond within the first two years. In the year of completion, three species reproduced successfully: green toad Bufo viridis, European tree frog Hyla arborea and marsh frog Rana ridibunda. A further three species reproduced in the pond over the next two years: European fire-bellied toad Bombina bombina, common toad Bufo bufo and agile frog Rana dalmatina. Two smooth newts Triturus vulgaris were also recorded. The 2 ha pond was sealed with a layer of clay and was completed in 1990. The slope, shore and planting scheme were created to attract amphibians and dragonflies and to discourage human disturbance. Amphibians were monitored during 30 visits in March-October by visual surveys and hand-netting.
