Occurrence of forest ecosystem services

Wood Basic information: the data shows the 20% of forests supplying the largest amount of timber on a per unit area basis. Timber provision is measured in terms of growing stock volume (m3/ha). Pixels with a value of 1 identify the top suppliers, whereas pixels with a value of 0 identify other forested land parcels (i.e. bottom 80%).

Water supply Basic information: the data shows the 20% of forests supplying the largest amount of freshwater on a per unit area basis. Water supply is measured as mm/year. Pixels with a value of 1 identify the top suppliers, whereas pixels with a value of 0 identify other forested land parcels (i.e. bottom 80%).

Erosion control Basic information: the data shows the 20% of forests providing the most powerful action of erosion control on a per unit area basis. Erosion control is measured as avoided soil erosion (tons/ha year). Pixels with a value of 1 identify the top suppliers, whereas pixels with a value of 0 identify other forested land parcels (i.e. bottom 80%).

Pollination Basic information: the data shows the 20% of forests showing the strongest pollination potential on a per unit area basis. Pollination potential is a qualitative indicator measuring the capacity of ecosystems, including forest edges, to support pollinator insects. Pixels with a value of 1 identify the top suppliers, whereas pixels with a value of 0 identify other forested land parcels (i.e. bottom 80%).

Habitat provision Basic information: the data shows the 20% of forests with the strongest relative potential as a habitat for bird species. Habitat provision is expressed as the ratio (%) between local bird species richness and the average richness in the regional context (250-km radius). Pixels with a value of 1 identify the top suppliers, whereas pixels with a value of 0 identify other forested land parcels (i.e. bottom 80%).

Soil formation Basic information: the data shows the 20% of forest soils storing the largest amount of organic carbon on a per unit area basis. Soil organic carbon is intended as the content of organic carbon in both the topsoil (0-30 cm) and the subsoil (30-100 cm), and is measured in tons/ha. Pixels with a value of 1 identify the top suppliers, whereas pixels with a value of 0 identify other forested land parcels (i.e. bottom 80%).

Climate regulation Basic information: the data shows the 20% of forests storing the largest amount of above- and below-ground carbon on a per unit area basis. The data, which is expressed in tons/ha, accounts for forest type (coniferous or broadleaved) and ecological zone. Pixels with a value of 1 identify the top suppliers, whereas pixels with a value of 0 identify other forested land parcels (i.e. bottom 80%).

Recreation Basic information: the data shows the 20% of forests guaranteeing the highest recreation potential on a per unit area basis. The recreation potential is a qualitative indicator accounting for recreational quality and accessibility. Pixels with a value of 1 identify the top suppliers, whereas pixels with a value of 0 identify other forested land parcels (i.e. bottom 80%).
