Glossary
Leakage Increase in GHG emissions by sources or decrease in carbon stock in carbon pools which occurs
outside the boundary of an A/R CDM project activity or PoA, as applicable, which is measurable and
attributable to the A/R CDM project activity or PoA, as applicable.
Litter 4
Includes all non-living biomass with a diameter less than a minimum diameter chosen by the
country (for example 10 cm), lying dead, in various states of decomposition above the mineral
or organic soil. This includes the litter, fumic, and humic layers. Live fine roots (of less than the
suggested diameter limit for below-ground biomass) are included in litter where they cannot be
distinguished from it empirically.
Non-forest woody vegetation Woody vegetation which does not reach the threshold for forest definition, e.g. single trees and shrubs.
Project boundary The geographic delineation of the A/R CDM project activity or CPA under the control of the project
participant as determined in accordance with the CDM rules and requirements.
Silvopastoral activities Integration of trees with forage and livestock production (grazing) on forest land.
Soil organic carbon 4
Includes organic carbon in mineral and organic soils (including peat) to a specified depth chosen
by the country and applied consistently through the time series. Live fine roots (of less than the
suggested diameter limit for below-ground biomass) are included with soil organic matter where
they cannot be distinguished from it empirically.
Thinning Selective removal of trees to reduce stand density and competition between trees in a stand,
primarily undertaken to improve the growth rate or health of the remaining trees.
Wetland Area of land whose soil is saturated with moisture either permanently or seasonally.
