1.2.2.3 Forest Land

Definition: Those ecosystems that have a tree crown density (crown closure percentage) of 10% or more and are stocked with trees capable of producing timber or other wood products. This includes land from which trees have been removed to less than 10%, but which have not been developed for other uses.

Forest Land Categories:

1.2.2.3.1 Deciduous Forest Land: All forest ecosystems having a predominance of trees that lose their leaves at the end of the frost- free season or at the beginning of a dry season. This does not include tropical hardwoods and deciduous forest types characteristic of wetlands are not included in this category.

1.2.2.3.2 Evergreen Forest Land: All forest ecosystems having a predominance of trees that remain green throughout the year. This includes both coniferous and broad-leaved evergreens. In most areas, the coniferous evergreens predominate, but some of the forests of Hawaii are notable exceptions. This does not include evergreen species commonly associated with wetlands.

1.2.2.3.3 Mixed Forest Land: All forest ecosystems where both evergreen and deciduous trees are growing and neither predominates. This includes forestland where evergreen and deciduous trees each represent at least one-third of the land cover.
