But this has also triggered much practical and fundamental research aimed at understanding the mechanisms of wet ecosystem decline in the Netherlands. During the eighties and nineties the government decided to buy out farmers in areas where modern agriculture was no longer viable and hand them over to nature conservation organizations. Such areas were then transformed into nature areas, by raising water levels and decreasing nutrient availability. During that period much knowledge was developed in restoring wet ecosystems that had been in former agricultural use. We aim to show the participants areas where scientific and practical knowledge in Dutch restoration areas has developed.
