Biome classification

Natural vegetation types (biomes) are classified based on the area shares of the plant functional types (PFT)s and their foliage projected cover (FPC); the mean temperature; and net primary production (NPP) according to the flowchart below.


Flowchart for the classification of natural land cover types (biomes) based on of plant functional types
Natural land cover type (biome) classification from area shares of individual Plant Functional Types (PFT)s (expresses as foliage projected cover, FPC) and mean annual temperature (Tmean). Subscripts of FPC refer to individual PFTs (1: tropical broadleaved evergreen, 2: tropical broadleaved raingreen, 3: temperate needleleaved evergreen, 4: temperate broadleaved evergreen, 5: temperate broadleaved summergreen, 6: boreal summergreen, 7: boreal needleleaved evergreen, 8: C3 herbaceous, 9: C4 herbaceous), tropical PFTs (“trop”) are PFTs 1 and 2, temperate PFTs (“temp”) are PFTs 3-5, boreal PFTS (“bor”) are PFTs 6 and 7, tree PFTs (“tree”) are PFTs 1-7, grass PFTs are PFTs 8 and 9.
