Temperate and Boreal Forest Types

1 Evergreen needleleaf forest
Natural forest with > 30% canopy cover, in which the canopy is predominantly (> 75%) needleleaf and evergreen.
2 Deciduous needleleaf forest
Natural forests with > 30% canopy cover, in which the canopy is predominantly (> 75%) needleleaf and deciduous.
3 Mixed broadleaf/needleleaf forest
Natural forest with > 30% canopy cover, in which the canopy is composed of a more or less even mixture of needleleaf and broadleaf crowns (between 50:50% and 25:75%).
4 Broadleaf evergreen forest
Natural forests with > 30% canopy cover, the canopy being > 75% evergreen and broadleaf.
5 Deciduous broadleaf forest
Natural forests with > 30% canopy cover, in which > 75% of the canopy is deciduous and broadleaves predominate (> 75% of canopy cover).
6 Freshwater swamp forest
Natural forests with > 30% canopy cover, composed of trees with any mixture of leaf type and seasonality, but in which the predominant environmental characteristic is a waterlogged soil.
7 Sclerophyllous dry forest
Natural forest with > 30% canopy cover, in which the canopy is mainly composed of sclerophyllous broadleaves and is > 75% evergreen.
8 Disturbed natural forest
Any forest type above that has in its interior significant areas of disturbance by people, including clearing, felling for wood extraction, anthropogenic fires, road construction, etc.
9 Sparse trees and parkland
Natural forests in which the tree canopy cover is between 10-30%, such as in the steppe regions of the world. Trees of any type (e.g., needleleaf, broadleaf, palms).
10 Exotic species plantation
Intensively managed forests with > 30% canopy cover, which have been planted by people with species not naturally occurring in that country.
11 Native species plantation
Intensively managed forests with > 30% canopy cover, which have been planted by people with species that occur naturally in that country.
Unspecified forest plantation
Forest plantations showing extent only with no further information about their type, This data currently only refers to the Ukraine.
Unclassified forest data
Forest data showing forest extent only with containing no further information about their type.

Tropical Forest Types

12 Lowland evergreen broadleaf rain forest
Natural forests with > 30% canopy cover, below 1200m altitude that display little or no seasonality, the canopy being >75% evergreen broadleaf.
13 Lower montane forest
Natural forests with > 30% canopy cover, between 1200-1800m altitude, with any seasonality regime and leaf type mixture.
14 Upper montane forest
Natural forests with > 30% canopy cover, above 1800m altitude, with any seasonality regime and leaf type mixture.
15 Freshwater swamp forest
Natural forests with > 30% canopy cover, below 1200m altitude, composed of trees with any mixture of leaf type and seasonality, but in which the predominant environmental characteristic is a waterlogged soil.
16 Semi-evergreen moist broadleaf forest
Natural forests with > 30% canopy cover, below 1200m altitude in which between 50-75% of the canopy is evergreen, > 75% are broadleaves, and the trees display seasonality of flowering and fruiting.
17 Mixed broadleaf/needleleaf forest
Natural forests with > 30% canopy cover, below 1200m altitude, in which the canopy is composed of a more or less even mixture of needleleaf and broadleaf crowns (between 50:50% and 25:75%).
18 Needleleaf forest
Natural forest with > 30% canopy cover, below 1200m altitude, in which the canopy is predominantly (> 75%) needleleaf.
19 Mangroves
Natural forests with > 30% canopy cover, composed of species of mangrove tree, generally along coasts in or near brackish or salt water.
20 Disturbed natural forest
Any forest type above that has in its interior significant areas of disturbance by people, including clearing, felling for wood extraction, anthropogenic fires, road construction, etc.
21 Deciduous/semi-deciduous broadleaf forest
Natural forests with > 30% canopy cover, below 1200m altitude in which between 50-100% of the canopy is deciduous and broadleaves predominate (> 75% of canopy cover).
22 Sclerophyllous dry forest
Natural forests with > 30% canopy cover, below 1200m altitude, in which the canopy is mainly composed of sclerophyllous broadleaves and is > 75% evergreen.
23 Thorn forest
Natural forests with > 30% canopy cover, below 1200m altitude, in which the canopy is mainly composed of deciduous trees with thorns and succulent phanerophytes with thorns may be frequent.
24 Sparse trees and parkland
Natural forests in which the tree canopy cover is between 10-30%, such as in the savannah regions of the world. Trees of any type (e.g., needleleaf, broadleaf, palms).
25 Exotic species plantation
Intensively managed forests with > 30% canopy cover, which have been planted by people with species not naturally occurring in that country.
26 Native species plantation
Intensively managed forests with > 30% canopy cover, which have been planted by people with species that occur naturally in that country.
