Abstract
Summary The main stages of well managed and degraded wet and moist meadows are reviewed together with their respective species diversity. Results of three case studies are presented, demonstrating changes in species diversity under various management and experimental treatments. The studies are of (a) alluvial meadows; (b) wet meadows adjacent to a standing water body; (c) submontane moist meadows. Results indicate that despite the great degradation of the majority of moist (i.e. slightly wet) and wet meadows in the Czech Republic, potential still exists to restore many of them. Re—establishment of a regular cutting regime and a decrease in nutrient inputs are necessary for successful restoration or rehabilitation of the meadows, which can be rapid under certain conditions, especially if the input of diaspores of desirable species is ensured, such as in many flooded alluvial meadows. Résumé Les principaux types de prairies humides bien gérées et dégradées sont présentés avec leurs diversités spécifiques respectives. Les résultats de trois études de cas sont donnés, montrant les changements de diversité spécifique sous différents modes de gestion et traitements expérimentaux: (a) des prairies alluviales, (b) des prairies humides avec une nappe d'eau perchée, (c) des prairies fraîches submontagnardes. Les résultats indiquent que, malgré la dégradation importante de la majorité des prairies humides de la République Tchèque, un potentiel de restauration existe encore pour un grand nombre d'entre elles. Le rétablissement d'un régime de fauche régulier et la diminution des apports de nutriments sont les conditions nécessaires à une restauration ou réhabilitation réussie des prairies. Celle—ci peut être rapide sous certaines conditions, en particulier si l'apport de diaspores des espèces désirables est assuré, comme c'est le cas dans de nombreuses prairies inondables.
