Outdoor recreation activities- Supply

General description:

<font 14px/inherit;;inherit;;inherit>The supply of outdoor recreation is collected in three steps: First, we map the recreation potential provided by ecosystems, then the accessibility is calculated, and finally both aspects are integrated into one map.</font>

<font 14px/inherit;;inherit;;inherit>Different landscape variables serve as indicators for the recreation potential. These are all based on recent literature (see table 1). Every dataset was converted to raster data with a spatial resolution of 100 m in order to easily overlay them. Furthermore, all indicators were considered to equally contribute to the recreation potential and were rescaled to 0–100. In a last step, they were then overlaid to obtain a recreation potential index (Paracchini et al., 2014). The recreation potential index ranges from 0 (low) to 100 (high) and was further analysed considering accessibility. All calculations were performed using standard routines provided with ArcGIS 10.4. The following explanations are quoted directly from the supplementary material of Schirpke et al. (2017).</font>

Input Data

<font 14px/inherit;;inherit;;inherit>Protected areas</font>

  • <font 14px/inherit;;inherit;;inherit>DEM</font>
  • <font 14px/inherit;;inherit;;inherit>Open street map</font>
  • <font 14px/inherit;;inherit;;inherit>Landcover</font>

Calculation processes:

<font 14px/inherit;;inherit;;inherit>(3) Calculate recreational value of protected areas</font>

<font 14px/inherit;;inherit;;inherit>Natural environment and high biodiversity contribute considerably to recreational value (Sonter et al., 2016) and, thus, protected areas are considered public recreation areas (Paracchini et al., 2014). The recreational value of protected areas was mapped considering the Natura 2000 network and the Common Database on Designated Areas (CDDA) (EEA, 2015a, b). The Natura 2000 network consists of sites designated under the Birds Directive (Special Protection Areas, SPAs) and the Habitats Directive (Sites of Community Importance, SCIs, and Special Areas of Conservation, SACs). The CDDA is an inventory of nationally designated areas. The database follows the IUCN (International Union for Conservation of Nature and Natural Resources) categories, classifying protected areas according to their management objectives. Protected areas from the Natura 2000 network and the CDDA were overlaid and reclassified in relation to their importance for recreational uses according to Zulian et al. (2013) (Table 1). The score ranges from 0 to 100. The highest score was assigned to the category of protected areas with the highest natural value, whereas 0 was used for sites that are inaccessible for recreation purposes (category Ia).</font>

<font 12.0pt/inherit;;inherit;;inherit>(4) Reclassify to hemeroby classes</font>

<font 14px/inherit;;inherit;;inherit>The degree of environmental naturalness (hemeroby) is one of the most important factors when selecting locations for outdoor recreation (Peña et al., 2015; Willemen et al., 2008). The hemeroby index measures the extent of human impacts on the natural environment on a scale from 1 (natural) to 7 (artificial) and can be attributed to land cover types (Steinhardt et al., 1999; Wrbka et al., 2004). The hemeroby was calculated based on CORINE land cover data (EEA, 2016a). All land cover types were attributed to the hemeroby classes as proposed by Paracchini and Capitani (2011). The index was inverted to assign highest recreational values to more natural environments and rescaled from 0 to 100.</font>

<font 14px/inherit;;inherit;;inherit>(5) Calculate distance to water</font>

<font 14px/inherit;;inherit;;inherit>Water offers a variety of recreational opportunities (Keeler et al., 2015) and has a high visual attraction compared with or in conjunction with surrounding areas (Arriaza et al., 2004; Ode et al., 2009). To calculate the influence of water bodies on the recreation potential, inland and marine water bodies were extracted from the CORINE land cover database (EEA, 2016a). The Euclidean distance was calculated up to 2,000 m from the coastline of seas and lakes, and the recreational potential was assessed by applying an impedance function (Paracchini et al., 2014) and subsequently rescaled from 0 to 100, resulting in high values for areas close to the coastline.</font>

<font 14px/inherit;;inherit;;inherit>(6) Calculate number of land cover types</font>

<font 14px/inherit;;inherit;;inherit>Diverse landscapes provide high recreational and visual attractiveness (Kienast et al., 2012; Ode et al., 2009; Schirpke et al., 2016). The landscape diversity was assessed by calculating the number of different land cover types per km2 (Kienast et al., 2012) based on the CORINE land cover database (EEA, 2016a). The result was rescaled from 0 to 100. Great landscape diversity indicates high recreation potential.)</font>

<font 14px/inherit;;inherit;;inherit>(7) Calculate Terrain roughness</font>

<font 14px/inherit;;inherit;;inherit>Rough landscapes provide many recreational opportunities and are visually more appealing than flat landscapes (Weyland & Laterra, 2014). The Terrain Ruggedness Index (TRI) reveals the degree of topographic heterogeneity by measuring elevation differences between adjacent cells (Riley et al., 1999). We calculated the TRI based on the DEM (EEA, 2016b), which was aggregated to 100 x 100 m and classified into seven classes as proposed by Riley et al. (1999). All scores were rescaled from 0 to 100. High ruggedness suggests high recreation potential.</font>

<font 14px/inherit;;inherit;;inherit>(8) Calculate density of mountain peaks</font>

<font 14px/inherit;;inherit;;inherit>Mountain peaks are very attractive for recreation, providing opportunities, for example, for mountaineering and climbing (Pomfret, 2011). Furthermore, they can be considered as a proxy for long vistas and remoteness (Kienast et al., 2012), and influence people’s choices for recreational purposes due to their high visual attractiveness (D'Antonio & Monz, 2016). We used the density of mountain summits as an indicator for recreation potential, as also applied by other studies (Kienast et al., 2012; Peña et al., 2015).</font>

<font 14px/inherit;;inherit;;inherit>To select important mountain summits on a local to regional level, several steps were applied following Podobnikar (2012):</font>

  • <font 14px/inherit;;inherit;;inherit>Calculation of local peaks by applying a moving window with the kernel of size 5 × 5 cells (focal statistics; maximum) based on the DEM (EEA, 2016b) using a spatial resolution of 100 m</font>* <font 14px/inherit;;inherit;;inherit>Selection of local peaks above 600 m</font>* <font 14px/inherit;;inherit;;inherit>Elimination of local peaks on flat areas (curvature > 0.2: significant concave areas; ruggedness >= moderately rugged)</font>

<font 14px/inherit;;inherit;;inherit>The density of the identified mountain peaks was then calculated by counting the peaks per 10 km2 by applying a moving window. The resulting values were reclassified from 0 to 100, with high density of mountain peaks representing high recreation potential.</font>

<font 14px/inherit;;inherit;;inherit>(9) Calculate recreation potential</font>

<font 14px/inherit;;inherit;;inherit>All indicators were considered to equally contribute to the recreation potential. All indicators, which were first rescaled to 0–100, were overlaid to obtain a recreation potential index (Paracchini et al., 2014) by summing all layers and dividing them by 6 (number of all layers). The recreation potential index ranges from 0 (low) to 100 (high).</font>

<font 14px/inherit;;inherit;;inherit>(10) Calculate accessibility</font>

<font 14px/inherit;;inherit;;inherit>Accessibility through infrastructure determines whether suitable recreation areas can be used, and proximity to residential areas is a crucial factor for the use of recreational sites (Ala-Hulkko et al., 2016; Kienast et al., 2012; Paracchini et al., 2014; Peña et al., 2015; Weyland & Laterra, 2014). We therefore identified the accessible areas as well as the level of accessibility defined by the proximity to residential areas.</font>

<font 14px/inherit;;inherit;;inherit>First, we identified recreational areas that are accessible through infrastructure such as paved and unpaved roads, hiking trails, and cycling paths. Information on the road network was obtained from OpenStreetMap (OSM, 2016), which was used to calculate the Euclidean distance from roads and paths. Assuming that people would rather stick to existing paths and trails for most recreational activities rather than moving off-road, accessible areas were mapped by selecting all areas up to 1,500 m distance from the road network, as this distance contributes most to visual landscape enjoyment (Schirpke et al., 2013).</font>

<font 14px/inherit;;inherit;;inherit>To assess the level of the supply, we calculated the proximity of recreational areas from residential areas in terms of travel time by private car (on paved roads) and foot (on roads and paths closed for cars). The road network contained information on the maximum speed of most roads. Missing data were integrated by assigning each type of road a mean travelling velocity. Further, we assumed an average off-road velocity of 1 km/h, to include the whole surface of the study area into the calculation. Residential areas were extracted from the CORINE land cover database (EEA, 2016a) (classes ‘continuous urban fabric’ and ‘discontinuous urban fabric’). The travel time from urban areas was then estimated using the cost distance algorithm as implemented in ArcGIS 10.4 (ESRI, Redlands, CA, USA). The resulting travel time was rescaled from 0 to 1.</font>

<font 14px/inherit;;inherit;;inherit>(11) Calculate recreation supply (status)</font>

<font 14px/inherit;;inherit;;inherit>The recreation potential was overlaid with the level of accessibility by multiplying the two layers in order to exclude inaccessible areas and map the recreation supply.</font>
