Commercial Thinning (CT) is much the same as pre-commercial thinning:
|
Stands are aged 35-45 years
|
|
Dense stands of natural regeneration are thinned to
between 2000 and 2500 tree per hectare
|
|
Primary objective is to stimulate growth of crop trees
|
|
Any merchantable timber cut is salvaged and sold as
pulpwood, fuel wood, or sawlogs
|
|
Extraction trails are required to remove salvaged timber
to roadside
|
|
Chainsaw is the tool of choice because of larger sized
trees
|
|
Less than 2500 hectares treated in this fashion to date,
but treatment has great potential
|
|
Industry wishes to acquire more wood from CT and other
forms of selective harvesting as an alternative to clear-cutting only |
