This work presents the state of the art of aquatic and semi-aquatic ecological restoration projects in The Netherlands. Starting from the conceptual basis of restoration ecology, the successes and failures of hundreds of restoration projects are described. Numerous successful projects are mentioned. In general ecological restoration endeavours greatly benefit from the progressive experience achieved in the course of the years. Failures mainly occur through insufficient application of physical, chemical or ecological principles. Spontaneous colonization by plants and animals, following habitat reconstruction, is preferred. However, sometimes the re-introduction of keystone species (e.g. eelgrass, salmon, beaver) is necessary in case the potential habitats are isolated or fragmented, or if a seed bank is lacking, thus not allowing viable populations to develop. Re-introducing traditional management techniques (e.g. mowing without fertilization, low intensity grazing) is important to rehabilitate the semi-natural and cultural landscapes that are so characteristic for The Netherlands.
This l:::ook comes as part of a new series on Solar Energy R+D, includlng Biomass which is carried out by the Euro:pean Community.. The commission of the European Comrmmities' Directorate General (XII) for Science, Research and Developnent is currently implementing, on a cost-sharing basis, a solar energy R+D pro;Jranune through contracts with European industry, research institutions and uni versi ties. This prcgrarrrrne includes a very strong acti vi ty on Biomass. Besides general R+D work on all aspects of Biomass growth and utilization which is reported elsewhere in this series, the Canmission is currently starting a new activity on Pilot Plants based on the use of Biomass for energy purp:Jses, and in particular on methanol prcx:luction from wood. The commission considers that the subject of methanol prcxiuction from wood offers llnp:Jrtant prospects for application wi thin the European Canmilllity and in other parts of the world, in particular some of the developing countries & The state of art in Europe In this field is still considered to be very high as a result of related work which was performed in Europe during ~vorld War II and the time before.
