T5. Growing stock

The information on “growing stock” is essential to understand dynamics of forest stands, their productive capacity and to manage their use within limits of sustainability defined by their dynamics of growth.

A. Global Classification and Definitions (FRA 2005)

Growing Stock

Volume of all living trees more than X cm in diameter at breast height (or above buttress if these are higher) measured over bark from ground or stump height to a top stem diameter of Y cm, excluding or including branches to a minimum diameter of Z cm. Excludes: smaller branches, twigs, foliage, flowers, seeds, stump and roots.

Commercial Growing Stock

The part of the growing stock of species, considered as actually or potentially commercial under current market conditions, measured above a minimum say “X cm” diameter at breast height. Includes: all potentially commercial (merchantable) species for domestic or international markets.

T6. Biomass Stock of Forests

The information on “biomass stocks” is essential to assess the total and the annual capacity of “forests” and Other Wooded Land” to sequester carbon. The annual growth (capacity) defines their sustenance limits of use and management needs and opportunities.

A. Global Classification and Definitions (FRA 2005)

Above Ground Tree Biomass

The mass, expressed as oven-dry weight (including or excluding bark), of the woody parts (stem, bark, branches and twigs) of all living trees excluding stump and roots.

A. Global Classification and Definitions

Primary Employment

The employment provided within the “Forest and “Other Wooded Land” by activities relating to primary (raw) production of goods, provision of services, and other primary activities.

Primary Activities

The forestry activities within the “Forest” and “Other Wooded Land”. FRA 2005 classifies forestry activities into three broad classes; activities relating to “Wood Supply”, “Non Wood Forest Product Supply” and “Other Primary Activities”.

Other Primary Activities

The forestry activities, within the “Forest” and “Other Wooded Land”, other than those related to “Wood supply” (including “wood fuel” or “fuelwood” supply) and collection of “NWFP”.
