Land cover types
- Agricultural land: Cropped land, fallow land and grassland (excluding extensive grassland)
- Extensive grassland: Land covered by grass with potential productivity of less than 25% of world maximum for grassland
- Biofuel Land: cropped for biofuels
Managed forest land and regrowing vegetation
- Carbon plantation: Lands planted with wood species used for biofuel production or C sequestration
- Regrowing vegetation (abandoning): Abandoned agricultural land that reverts back to its natural vegetation
- Regrowing vegetation (timber): Vegetation harvested for timber or fuelwood production that reverts back to its natural vegetation type
- Wood plantations: Planted forests where management is optimized for efficient wood production with shorter rotation cycles.

- Wooded tundra
- Boreal forest
- Cool coniferous forest
- Temperate mixed forest
- Temperate deciduous forest
- Warm mixed forest
- Grassland and steppe

Areas not shown on land cover maps or graphs
- Built-up areas; Urban and built-up areas (fractions of grid-cells covered by built-up areas are excluded from being used for agricultural practices).
- Bioreserves: Protected nature reserves, national parks and monuments occurring within the above natural vegetation types; these areas are excluded for being used as managed forest or agriculture.
