An example of ecological thinning research is the project in Victoria's Box-Ironbark forests, investigating various thinning and timber removal methods under an adaptive management or AEM framework. The primary objective is to generate (over time) a number of forest habitat values (i.e. tree hollows ) that are crucial for wildlife conservation .
Thinning from below – this low thinning can be split into 4 Grades: A Grade is a very light thinning, that removes all overtopped trees Kraft crown class 4 and 5. B Grade is a very light thinning that removes overtopped trees and intermediates which are Kraft Crown class 4,5 and some 3s, C Grade and D Grade are a moderate and heavy thinning respectively removing anything that will not lead ...
Advantages of extended rotation forestry included enhanced carbon storage, better wood quality and the ability to create habitat for old growth dependent species. The main disadvantages of extended rotations is the lower present value of the stand and timber supply issues. These impacts can be mitigated by the application of commercial thinning.
Salvage logging is the practice of logging trees in forest areas that have been damaged by wildfire, flood, severe wind, disease, insect infestation, or other natural disturbance in order to recover economic value that would otherwise be lost.
As the trees grow and become dense and crowded again, the thinning process is repeated. Depending on growth rate and species, trees at this age may be large enough for timber milling; if not, they are again used as pulp and chips. Around year 10-60 the plantation is now mature and (in economic terms) is falling off the back side of its growth ...
Thinning – removal of trees to favor the growth of select trees in order to maximize timber production; Ecological thinning – removal of trees to favor the growth of select trees in order to favor the development of wildlife habitat; Pruning – removal of the lateral branches on the trees in order to improve wood quality
This silviculture regime provides post-harvest ecological structure while creating sufficient opportunity to plant and naturally regenerate valuable tree species for timber, as well as restore historical coniferous and/or deciduous tree dominance to the forestland. Some timber companies have restricted the use of variable retention silviculture ...
From the ecological point of view, the introducing species is considered as a threat. The introduced species risks being invasive . Invasives displace local species, resulting in a reduction of biodiversity , a condition also to be expected if great extensions are forested using introduced species.
