Glossary of Terms
- ABARE:
- Australian Bureau of Agricultural & Resource Economics
- ABS:
- Australian Bureau of Statistics
- AFC:
- Australian Forestry Council
- Allocation:
- the right of access to a parcel of
wood. - Balance of trade:
- the difference between the
value of a country's
exports and imports of merchandise or of goods and service. - Cable logging:
- operation where logs on steep
slopes are removed with the use of cables above the ground. - Clearfelling:
- the most intense harvesting
technique where virtually all trees are removed at one time. Often associated
with plantation harvesting or land clearing for agriculture. As a forest
management technique it is applied in particular forest types (e.g. karri)
but habitat and seed trees are left. When regrown, forests are even aged. - Codes of practice:
- State regulations which control
where and the way logging is conducted. - Compartment:
- series of logging coupes.
- Coupe:
- smallest forest management area of varying
size, shape and orientation from which logs for sawmilling are harvested. Coupes
are regenerated
after logging. - Formply:
- type of plywood used for moulding
concrete. - Fine papers:
- writing, printing and cover papers
with high quality characteristics. - Flitch:
- a large piece of sawn log intended for
further cutting. - Gross domestic product:
- is equivalent to gross
national expenditure plus export of goods and services less imports of goods
and services. It measures the output of economic activity. - Integrated harvesting:
- harvesting both sawlogs
and pulpwood in a single operation. Can mean the removal of 90% of the canopy
in a logging coupe in forest types that require full sun for regeneration. Seed
trees, habitat trees and saplings remain. - Management plan:
- objectivities and strategies, laid
down by Forest Services, for the long term multiple use of State forests. - Medium density fibreboard:
- a kind of particleboard
made by gluing and compressing small wood particles together. - Mouldings:
- architraves and door frames; usually
made from tropical timbers because of their easy application. - Plywood:
- wood panel formed by gluing and compressing
thin sheets of veneer. - Pulp:
- material consisting of separate fibres used to
make paper. - Pulpwood:
- Wood considered unsuitable for sawmilling
and used for the production of woodchips, pulp, paper and wood panels. - Reconstituted wood products:
- wood products made by
compressing particles or pieces of wood together. - Recovery rate:
- the proportion of timber recovered
from a log for a particular purpose e.g. for sawn timber. - Royalties:
- fees paid for harvested timber to the
Crown or private landowner. - Sawlogs:
- logs which are processed into sawn timber,
veneer, poles and sleepers. The residue may be processed into woodchips or
pulpwood. - Sawmill residues:
- are what is left after sawn timber
has been cut from a log including roundbacks, shavings and sawdust. - Sawn timber:
- solid timber sawn into particular
dimensions, to be used for construction or furniture. - Seasoned timber:
- solid timber which has been dried
in a kiln or naturally. - Selective harvesting:
- is where small groups or
single mature trees are removed, together with some thinning of the forest
stand to encourage regeneration and maintain an uneven aged stand. - Thinning:
- the removal of trees from a stand
to increase the growth rates of the remaining trees. - Value adding:
- processing of the raw material
e.g. converting woodchips into paper is value adding. - Veneer:
- a thin layer or sheet of wood material
either peeled or sliced from a length of log. - Woodchipping:
- production of small pieces of wood
from pulpwood - the first stage of processing pulpwood into paper and
fibreboard. - Woodchips:
- small pieces of pulpwood cut into
particular dimensions for different purposes including pulp and paper
manufacture and panel production.
