kokonaiskorkeustilavuus

Kokonaiskorkeustilavuus, often abbreviated as KKT, is a Finnish term that translates to "total height volume" or "gross volume." In forestry and related fields, it refers to the total volume of a tree or a stand of trees, measured from the stump to the tip of the tree. This measurement includes all parts of the tree, such as the trunk, branches, and foliage, without deducting for any defects or irregularities.

The calculation of kokonaiskorkeustilavuus is typically done using allometric equations or by direct measurement techniques. These methods often involve measuring the tree's diameter at breast height (DBH) and its total height. The resulting volume is usually expressed in cubic meters (m³) or cubic feet (ft³).

Kokonaiskorkeustilavuus is a fundamental metric used in forest inventory, resource management, and carbon stock estimations. It provides a baseline for understanding the total biomass present in a forest. However, it is important to note that KKT does not represent the usable timber volume, as it includes non-merchantable parts and potential defects. For practical timber harvesting, a concept like "käyttötilavuus" (usable volume) or "tukkipuun tilavuus" (sawlog volume) is more relevant, as these exclude unusable portions. Despite this, KKT serves as a crucial starting point for more detailed volume estimations and for assessing the overall growth and productivity of a forest ecosystem.
