The following is an alphabetical listing of some forestry terms

Agriculture

the cultivation of land, including crop raising, stock-raising and forestry.

Agroforestry

the combination of timber production and agriculture on the same land; farming activities, such as livestock and cropping, are undertaken between widely spaced trees usually cultivated for timber, firewood and/or fodder.

Angiosperms

flowering plants; plants which produce seeds enclosed in an ovary.

Breast height

1.3m above the ground. This is the standard height at which a tree diameter is measured.

Broadleaf forests

the general description of forests composed principally of trees and shrubs of the botanical group of flowering species (angiosperms) which is in contrast to conifers or pines (gymnosperms); often called hardwood forests, though in New South Wales broadleaf forests include both eucalypt forests (hardwood) and rainforest (brushwood or softwood).

Cable logging

Logging method used where slopes are too steep for conventional logging machinery. Overhead cables are set up and the felled logs are attached and pulled up the slope to log landings.

Canopy

the uppermost level of foliage formed by the branches and leaves of a tree.

Cellulose

a large molecule made up of glucose units naturally produced by plants, provides the strength of plant cell walls.

Chlorophyll

the pigment that gives plants their green colouring; it is required for the absorption of light during phothosynthesis.

Clearfelling

the removal of all or most of the tree cover and associated understorey from a forested or vegetated area, method used in the final harvesting of a pine plantation.

Clearing

o pen sites of non-forest lands located within a forest, covered with grasses and herbs, where all or most of the tree cover and associated understorey have been removed and the land use changed eg. for agriculture or urban and industrial development.

Closed forest

a forest with a canopy cover of greater than 70 per cent.

13. Cone the fruit of coniferous trees, contains the seeds of the plant.

Conifers

evergreen trees and shrubs which produce naked seeds usually in cones.

Controlled burning

Post – logging burn.

Copice

regrowth that grows from dormant buds under the bark of tree stumps after the tree has been felled.

Coupe

a small area of forest within a compartment that is harvested in a single operation.

Crown

the top of a tree or group of trees; the leaves and living branches of a tree.

Crown cover

the area covered by the crowns of trees growing closely together, often expressed as a percentage for the combined crown cover of trees in a defined area.

Cutting cycle

t he time interval between successive harvesting operations on the same area or within a given management area.

Cypress

an evergreen native coniferous tree which produces durable wood; also refers to the wood derived from a cypress tree.

DBH

abbreviation for the diameter of a tree at breast height (1.3 metres above ground level).

Deciduous

plants which shed their leaves annually.

Deforestation

clearing of forested areas.

Dieback

the eventual death of trees from environmental stresses, such as pest attack, exposure to fungal disease, increasing soil salinity; general name for a significant decline in tree health and numbers, especially native trees; caused by a variety of agents, including insect attack, disease, pollution and other human-induced changes in the environment.

Ecotourism

nature-based tourism which is ecologically sustainable.

Farm forestry

commercial tree production on farmland.

 

Fauna

the animal life of a region.

Farmsteads

plots of nonforest lands with service and residence buildings, of managerial and communal purposes for employees and workers of forest management (offices of FMUs and forest districts, stores, yards, garages, workshops, dwellings, as well as lands under settlement, rest facilities (campings, tents, rest bases, etc.), and those with elements of recreational facilities.

Feller buncher

a logging machine that fells trees, debranches, cuts to length and groups them ready to be removed with a forwarder or skidder.

Fire

the active principle of burning or combustion.

Flora

the plant life of a region.

Forest

an area of land covered by trees and understorey vegetation, sometimes mixed with pasture; forests are described in terms of crown cover, such as closed forest, open forest, woodland and open woodland, and in terms of height of the tallest stratum, such as tall (over 30 metres), medium (10-30 metres) and low trees (under 10 metres).

Forest cultures

plots of artificial forest stands created by planting or sowing. This category also includes forest plots where one has finished the stands’ reconstruction, done with the purpose of improving their species composition by introducing economically valuable tree species.

Forest district

(Rus. lesnichestvo)Primary territorial and operational subunit constituting the forest management unit.

Forest lands

lands suitable and intended for forest growing, as well as natural scarce open woodlands and shrubs.
