| Abstract |
In 1997-98 an area of approximately 1300ha of Flemish coastal dunes was censused for breeding birds. Territory maps were drawn and compared with maps on vegetation, hydrology and recreation pressure by the overlay method in a GIS. Twinspan recognized seven breeding bird communities; a DCA-ordination revealed the dominant importance of vegetation succession and the degree of urbanization for breeding bird community variance. Breeding habitats are characterized for all territorial songbirds. The comparison of the distribution of potential habitat and actually occupied habitat stresses the importance of increase of the groundwater level and recreation pressure for specific species. At the landscape level a positive relationship between area of shrub and grey dunes and species number was detected, an opposite relationship exists between area and total territory density. |
