afforestation: The establishment of a forest or plantation in an area where the preceding vegetation or land use was not forest – compare with “Reforestation”.

agroforestry: Agroforestry is the practice of combining agriculture and forestry technologies to create more integrated, diverse, productive, profitable, healthy and sustainable land-use systems.

biodiversity: The variety and abundance of life forms, functions and structures of plants, animals and other living organisms on earth. It includes genetic differences among species, the variety of species that live within a particular area (ecosystem) and the many such ecosystems or homes that exist on the planet.


1. Ecology The total dry organic matter at a given time of living organisms of one or more species per unit area (species biomass) or of all the species in the community (community biomass)
2. The living or dead weight of organic matter in a tree, stand, or forest in units such as living or dead weight, wet or dry weight, etc.
3. Harvesting the wood product obtained from in-woods chipping of all or some portion of trees including limbs, tops, and unmerchantable stems, usually for energy production.

board foot: (bd ft) The amount of wood contained in an unfinished board 1 inch thick, 12 inches long and 12 inches wide (2.54 cm x 30.5 cm x 30.5 cm).

carbon offset: The planting of trees on non-forested land such that the uptake of carbon dioxide from the growing trees will offset the production of carbon dioxide from industrial sources.

carbon sequestration: The incorporation of carbon dioxide into permanent plant tissues.

co-management agreements: The sharing of power, responsibility and benefits between the Government and resource users; provides a middle ground upon which the two can meet and cooperate.

community forest: A forest owned and generally managed by a community, the members of which share its benefits.

community forestry: Managing forests with the expressed intent of benefiting neighbouring communities. See also “social forestry”.

cubic metre: A unit of volume that measures 1 x 1 x 1 metres, most often used for volumes of standing timber or otherwise unsawn timber.

database: A collection of data stored in a systematic manner such that the data can be readily retrieved, modified and manipulated to create information, most often computerised.

deforestation: The removal of a forest where the land is put to a non-forest use.

dendrology: the scientific study of trees and woody plants, A branch of botany devoted to the study of trees and their identifying characteristics.

ecosystem: A self-regulating natural community of living things interacting with one another and with their non-living physical environment.

ecotourism: Travel undertaken to sites or regions of unique natural quality, or the provision of services to facilitate such travel.

forest: An ecosystem characterised by a more or less dense and extensive tree cover, often consisting of stands varying in characteristics such as species, composition, structure, age classs, and associated processes, and may include meadows, streams, fish, and wildlife. (Note that forests include special designations such as industrial forests, nonindustrial private forests, plantations, protection forests).

forest inventory: A set of objective sampling methods designed to quantify the spatial distribution, composition and rates of change of forest parameters within specified levels of precision for the purposes of management.

forest reserve: An area designated under a forest act in which timber production is allowed but not conversion to agriculture or other non-forest uses.

forestry: The profession embracing the science, art and practice of creating, managing, using, and conserving forests and associated resources for human benefit and in a sustainable manner to meet desired goals, needs and values. (agroforestry, urban forestry, industrial forestry, non-industrial forestry, and wilderness and recreation forestry).

fuelwood: Wood used for conversion into some form of energy, eg, cooking fires, charcoal production, energy-generating plants.

greenbelt: A park-like strip of unoccupied land with little or no development, usually surrounding or partially surrounding urban areas.

greenhouse effect: The warming effect exerted by the atmosphere upon the earth because the atmosphere (mainly its water vapour and carbon dioxide) absorbs radiant energy from the earth and re-emits infrared radiation or heat.

lumber: The sawn product from a tree – synonym is sawn wood.

natural forest: A forest in nearly natural condition, without any direct human intervention.

plantation forest: A forest or stand composed mainly of trees established by planting or artificial seeding.

reforestation: The re-establishment of forest cover either naturally or artificially. Note reforestation usually maintains the same forest type and is done promptly after the previous stand or forest was removed.

roundwood: A length of cut tree generally having a round cross section, such as a log.

silviculture: The art and science of controlling the establishment, growth, health and quality of forests to meet the diverse needs and values of society.

social forestry: Forestry programmes that purposefully and directly involve local people, their values and their institutions (also called development forestry, community forestry).

sustainable development:
1. Development that meets the needs of the present without compromising the ability of future generations to meet their own needs
2. Sustainable development is used to mean: improving the quality of human life while living within the carrying capacity of supporting ecosystems .

timber Wood: other than fuelwood, potentially useable for lumber.

tonne 1000 kg: in the context of “tonnes of fuelwood” in this document for air-dried hardwood, 1 tonne is approx. 1.38 cubic metres of wood.

urban forestry: The art, science and technology of managing trees and forest resources in and around urban community ecosystems for the physiological, sociological, economic and aesthetic benefits trees provide society.

watershed: A region or land area drained by a single stream, river, or drainage network.
