The landscape services were identied through ground observa-tions at 389 locations. Spatial indicators were used to identify and map the landscape services. Basedon the ground observations, correlations between the landscape services and spatial characteristics (e.g.elevation, soil, road-type) were calculated within a neighbourhood with a radius of 0m, 50m, and 100m.These correlations identied several site-specic indicators to map the landscape services.

The indicators proved to be adequately reliable forforest recreation and reasonably reliable for land-based animal husbandry and recreation for hikers. Onlylandscape service map forest recreation was shown to be highly accurate. The four landscape servicesrarely coincide, but within a 1km radius it is apparent that some occur closer together. The approachthat we have used is applicable for a wide range of different services and establishes a fundamental basisfor determining their spatial variation. As such, it should provide vital information for policy makers andspatial planners.

    ortance of landscape services, provided by both naturall landscapes, is increasingly recognised (e.g. CostanzaMA, 2005; de Groot, 2006; Termorshuizen and Opdam,rg et al., 2009). Landscapes are spatial social-ecologicalt deliver a wide range of functions, which are valued byterms of economic, sociocultural, and ecological ben-es et al., 2004; Termorshuizen and Opdam, 2009). Aervice is dened here as the goods and services pro-andscape to satisfy human needs, directly or indirectlyizen and Opdam, 2009). We prefer the term landscaper ecosystem services, as it infers pattern-process rela-nites scientic disciplines, and is better understood bytioners (Termorshuizen and Opdam, 2009). Examplese services include food production, pollination, waterand provision of recreation.

    Increasing attention is paid, both by policy makers and scien-tists, to the multifunctionality (Fry, 2001; Holmes, 2006; Wilson,2008) and the potential synergies and conicts that may arise.Policy makers and spatial planners are gradually directing theirpolicies and plans to provide and strengthen desired landscapeservices. To support the establishment of these policies and plans,geographical maps of existing and desired services are requiredto identify where services border each other or coincide and, thus,lead to possible synergies or conicts. In thisway, theymay be usedto determine optimal solutions. Hence, it is necessary to developmethods and tools to quantify andmap the different services acrossthe landscape.

    The spatial distribution of intended landscape services that arerelated to the intended land use (e.g. food and bre production)are often documented. However, the spatial distribution of land-scape services that are often an unintended consequence of landmanagement (e.g. provision of aesthetic beauty), are commonlyunknown. Additionally, they may be unrelated to a single land-coveror land-use type,whichmakes themmoredifcult toquantifyand map. It is postulated that landscape analyses based on land-cover and land-use are inadequate for landscape characterisation
