Crown: The leaves and branches of a tree measured from the lowest branch on the trunk to the top of the tree.

Leader: A dominant or co-dominant, upright stem.

Raise: Selective pruning to provide vertical clearance.

Reduce: Selective pruning to decrease height and/or spread by removing specified branches.

Restore: Selective pruning to improve the structure, form, and appearance of trees that have been severely headed, vandalized, or damaged.

Thin: Selective pruning to reduce density of live branches, usually by removing entire branches.

Vista pruning: Selective pruning to allow a specific view, usually by creating view “windows” through the tree’s crown.
