The value of the timber you ultimately sell at harvest time is linked to the value of the products these trees can make. Normally, as the size of individual trees in a timber stand increase in height and diameter, the more valuable that stand becomes as more "product classes" become growing into a more valuable class is what foresters call "ingrowth" . Young trees for timber production would be commonly planted on around 3 X 3 metre spacing. As they grow, from around years of age, low branches may be harvested (These are sometimes chipped, fed to stock, or sold for Christmas trees). Progressive pruning continues to encourage the development of quality timber (ie. straight and free of knots).
Pruning is a horticultural and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or s to prune plants include deadwood removal, shaping (by controlling or redirecting growth), improving or sustaining health, reducing risk from falling branches, preparing nursery specimens for transplanting, and both harvesting and . Pruning is a key silvicultural intervention in order to obtain high quality wood products since it influences the size of the knotty core and the proportion of clear-wood. However, little is known about knotty core size and its distribution through the pruned stem in timber conifers. This paper describes methodologies to predict knotty core profile and form along the Cited by: 3.
According to consulting forester Jim Birkemeier, a properly managed hardwood tree, such as a red oak, growing in southern Wisconsin adds 1 ⁄ 2" to its adult diameter each year."Combine that annual growth rate with increasing premiums for larger, quality logs and generally rising stumpage prices, and you get total value growth rates of percent a year for managed timber . Timber Usage: Timber from thinnings are used for the manufacturing of pulp, boxes and crates. Logs from mature ( year old) trees are used for building and construction timber. High quality logs are used for veneer and furniture.

Results in knotty core control and a high timber volume per hectare, but competition suppresses diameter growth - hence the need for a longer rotation.
(d) Pruning with heavy early thinning to minimise competition. knots are a major causes for timber quality downgrade. Pruning allows the early formation of clear knot free timber and improves timber quality.

All the above species, and also less light-demanding species (eg. oaks, Quercus spp.), can benefit from the use of rows of nurse trees. With the choice of a nurse species which grows at the same rate as the crop species, a straight form can be greatly encouraged; once the crop tree has a straight bole of the required length (usually m, ft), the nurse trees are thinned and.
Expert insight into the best time for conifer tree pruning; why you should prune a conifer tree, and how to identify common conifer tree diseases.
