Indicators and MapsIndicator Description●●●●●●●●Agricultural AreaThe share of agricultural area within a region gives information on the potentiallyutilizable area for agricultural purposes. It is calculated on the bases of CorineLand Cover classes 211-244.Farm Productivity (Average Standard Gross Margin, SGM)The SGM provides a measure of a holding's business size, irrespective of its areaand intensity of production. It is thus a measure for agricultural incomegeneration.No. of Part-Time FarmersThis indicator is based on the number of farm holder's being natural person with awork time below 25%. It indicates a shift of farming intensities towards a morediverse income generation, which is supposed to be more likely closer to the urbanfringe.Unsealed SoilThe unsealed soil is the opposite to the share of artificial surface. It highlightsareas where ecological processes, like groundwater recharge or soil developmentcan still take place in an undisturbed manner.Unfragmented Landscape (Effective Mesh Size Index, MESH)The MESH index is based on the probability that two individuals can meet in acertain area without barriers. It indicates the size of effective meshes, integratingthe extent and structure of fragmentation by transportation infrastructure andsettlements.Landscape Patchiness (Landscape shape index, LSI)The Landscape shape index provides information on class aggregation/disaggregation or clumpiness resp. patchiness of a landscape. It calculates theperimeter-to-area ratio of a landscape. When LSI increases, the patches becomeincreasingly disaggregated – providing more niches for different species andtherefore enhancing biodiversity (in a certain direction).Landscape Interspersion (Interspersion and juxtaposition index, IJI)The IJI takes the spatial configuration and neighbourhood of the patch types intoconsideration. The more patch types of an area are equally adjacent to each otherand are so directly neighbouring, the higher the IJI. It can be interpreted as theaccessibility of habitats of a certain kind.Density of Natural Habitats (Green Background Index)The Green Background Index is an indicator for naturality of a region; representingthe regional richness regarding natural land-cover types, provided by the EuropeanEnvironmental Agency. It is based on an aggregation of CORILIS components for“green” classes (Pastures & mixed farmland, Forests and transitional woodlandshrub, Natural grassland, Heathland, Sclerophylous vegetation, Open space withlittle or no vegetation and Water bodies).Page 6 • PLUREL report D2.3.14_15 • July 2010
●●Density of Endangered Bird SpeciesThe number of endangered bird species per 100km² is a measure of ecologicalintegrity of a region; It shows the importance for the preservation of endangeredspecies and is based on data from BirdLife International.Heavy Metal EmissionsFor the Heavy Metall Emissions an index was created, by cumulating and hazardpotential-weighing(thresholds) heavy metal emissions; It shows the degree ofpollution of air, water and soil from Heavy Metals. The database is the EPERdataset 2008 with the reporting year of 2001.Page 7 • PLUREL report D2.3.14_15 • July 2010
