Conservation of Leafhoppers in Floodplain Grasslands – Trade-off between Diversity and Naturalness in a Northern German National Park

Abstract

The impacts of mowing and of flooding on the leafhopper communities of a river flood plain were investigated. Samples were taken by a motor-driven suction apparatus. In 2001 leafhoppers were collected in a variety of sites differing in land use (fallows, mown sites) and in flood intensity (high, medium, low, none). In 2002 samples were only taken in fallows subject to different flooding regimes.
