2 European Forest Data Centre (EFDAC) Forest Focus database + BIOSOIL datasets (forest condition, forest fragmentation) Metadata Catalogue European Forest Fire Information System (EFFIS) European Forest Resources Information System (NFI data platform) Forest and forest type maps Data Sets at JRC Applications at JRC Services at JRC Related: Documents Projects Links

3 Objectives BIOSOIL Biodiversity Collect harmonised information relevant to forest biodiversity at European level Present European forest type (habitat) classification Test indicators of forest biodiversity Integrate information and ongoing projects (e.g., BioSoil) on forest biodiversity Quantify European forest biodiversity and monitor changes 3

4 Collected data General plot characteristics location, altitude, management, forest type Stand structure and composition Tree species, DBH, height, density Deadwood Type, dimensions, state of decay Ground vegetation species, cover

5 Forest types (14 classes) EFTC Null Boreal forest Hemiboreal & nemoral Scots pine forest Alpine coniferous forest Atlantic/nemoral oak/ashwoods, dune forest Oak-hornbeam forest Beech forest Montaneous beech forest Thermophilous deciduous forest Broadleaved evergreen forest Conif. forests of Med, Anatolian & Macronesia Swamp forest Floodplain forest Native plantations Exotic plantations and woodlands Distribution of scores Null

6 Age Age Class No information/unknown 1: 0-20 years 2: years 2: years 3: years 4: years 5: years 6: >120 years 7: Irregular stands Distribution of scores Irregular Unknown

7 Stand structure and composition Species richness 1-2 species 3-4 species 5-6 species 7-9 species species Distribution of scores
