Name: Naturalis Combined

Display Field:

Type: Raster Layer

Geometry Type: null

Description: Designated areas for nature protection do not exist in isolation to their surroundings. They are created for providing protection to natural features within their boundaries, as well as for providing refuge to nature in core areas which will in turn influence their neighbourhood and in many cases they are created to serve as corridors or nodes of ecological networks. Symmetrically, the long term sustainability of many high value habitats depends on their exchanges with their environment and/or similar habitats. Therefore, the areas of high ecological value to consider are not only important in themselves but their buffer zones as well (see definition of the ecological networks, CoE 2007 ). The buffers should reflect an influence which is proportional to the size and inversely proportional to the distance from the border of the designated area. This is the “potential in the neighbourhood” of designated areas. By analogy to CORILIS, the database of smoothed values of designated areas of high ecological value is called NATURILIS (or COMB_NATURILIS when several layers are combined). Without judging whether nature conservation has achieved all its objectives, the areas of high ecological value are defined, in a first instance, from the designated areas: CDDA national designations, Natura2000 sites, EMERALD sites, and other international designations. This restrictive approach, based on the value attributed by society, bears the advantage of a broad scientific consensus on the designated sites and consequently on available databases.
