Growing Stock, Increment and Harvest

Growing Stock

Timber stock is defined as the volume of standing wood, including bark, above a measurement threshold (10 cm), on a specific area, typically expressed in cubic meters per hectare. Timber stock is a key indicator for assessing the sustainability of forest resources. According to forest management plans by the Slovenian Forest Service, the timber stock of Slovenian forests amounts to 357,031,760 cubic meters, or 304 cubic meters per hectare.

Harvest

Harvest refers to the volume of wood actually felled during a specific time period, expressed in cubic meters per hectare annually. In recent years, between 4.0 and 6.3 million cubic meters of trees have been harvested annually in Slovenian forests, with conifers accounting for 55% to 66% of the total. In 2023, a total of 4,300,660 cubic meters of trees were harvested, including 2,487,760 cubic meters of conifers and 1,812,900 cubic meters of broadleaved trees.
