Natuurcombinaties en Europese natuurdoelen : ontwikkeling van een methode om natuurdoelen te realiseren buitenhet Natuurnetwerk Nederland

This study explored the possibilities for developing a method to determine what nature combinations outside Natura 2000 areas can contribute to the realisation of conservation objectives for Birds and Habitats Directive (BHD) species. A total of 54 species were selected that represent the BHD conservation objectives and for which the area outside the National Ecological Network is relevant; these are considered to be target species. For 43 of these species fiches were compiled containing a description of the most important habitat characteristics. An attempt was made to obtain a picture of the potential nature conservation effects of nature combinations related to conservation objectives. Using the ecological characteristics of the target species, an adapted version of the Model for Nature Policy (MNP) was developed to predict potential habitat from GIS information and the changes in habitat size and quality that can be brought about by nature combinations. An initial set of calculations was made for four species, limited to the eastern central region of the Netherlands. To obtain useful information it would appear necessary to have GIS data at a high level of spatial detail. Technically the model works and the first impression is that the results are ecologically plausible
