Ecological restoration of aquatic and semi-aquatic ecosystems in the Netherlands: an introduction

In 1989, a symposium was held under the title 'Netherlands-Wetlands', aiming at the presentation of the state of the art of the existing knowledge of structure and functioning of wetlands, characteristic for the Netherlands. The present multi-author volume can be seen as a logical successor of the results of this symposium. The focus is now fully on the results of ecological restoration measures over the past 25 years. The main question to be answered is what makes a project a success in terms of ecological performance, and when are we speaking about a failure? The present volume contains 10 case studies, roughly covering all aquatic and semi-aquatic ecosystems in the Netherlands.
