| Popis: |
The conversion of agricultural fields into nature is a demanding task for ecological restoration in the Netherlands. Such conversion is considered important to conserve and increase the surface of endangered habitats and to increase the connectivity between sites. Intensive agricultural use has lead to a very high nutrient content in such fields, making restoration of low-productive vegetation a difficult task. Several strategies to reach this goal have beenapplied during the last two decades: sod cutting c.q. removal of the complete nutrient rich top soil, mining of P through addition of a surplus of N and K, nutrient removal through mowing without fertilisation and/or grazing, stimulating P-binding, and not removing the nutrients but instead focus on different, more productive targets. Reasearch on the effectiveness of different techniques has been carried out both in the Netherlands and abroad but the results of the different studies seem to contradict each other. Such apparent controversies have also lead to controversies in the debate on the conversion of nutrient-rich agricultural fields including debates on the question whether or not to remove the entire top soil, how to handle the soil fauna, the question whether other strategies also allow for the restoration of low-productive habitats and how to best measure phosphate availability.The project has several goals:1. Summarising existing knowledge and comparing the effects of different restoration techniques for to low-productive habitats.2. Evaluation of practical projects on the conversion of agricultural fields into lowproductive nature.3. Elaborating a practical guidance for nature managers how to restore low-productive habitats including the required pilot research.4. Describing the most important knowledge gaps.The results are offered in two different forms, each for their own target audience:1. A background report (this OBN report) for staff members of nature conservation organisations and/or restoration managers who have to work out restoration plans in detail.2. A summary report (seperate publication) about potential strategies and necessary pilot studies. This report is intended for project managers of organisations involved in restoration. |
