Site Preparation

Site preparation equipment is used to prepare sites for reforestation. Site preparation can reduce competition from unwanted vegetation, mix mineral and organic soil layers, rearrange slash to increase the number of plantable spots and reduce hazards to tree planters. Depending on conditions found on the site Scott and Stewart may utilize various pieces of site preparation equipment.

Planting

Planting is used to fully stock a site with seedlings when natural regeneration to desired species is insufficient.

Weeding (Chemical)

Government approved herbicides are used under government approvals to release young crop trees from competing vegetation. The competing vegetation, if not controlled, can compete with the seedlings for sunlight, moisture and nutrients. Competing vegetation can stunt the growth of seedlings for years and in severe cases cause seedling mortality.

 Weeding (Manual)

Manual weeding is also used to release young crop trees from competing vegetation. Manual weeding may have to be carried out more than once if vigorous re-sprouting occurs.

Weeding (Manual / Chemical Combined)

When using tools such as an R-Jet applicator it is possible to apply herbicides to the cut stumps of unwanted vegetation during a pre-commercial thinning operation.

Pre Commercial Thinning (PCT)

Pre commercial thinning is carried out in young softwood plantations or natural stands that average two to seven meters in height. Allows the selection of healthy preferred trees as crop trees; Removes competing trees giving the crop trees room to grow; Like carrots in a garden thinning greatly increases the diameter growth of the remaining crop trees.

Pre Commercial Thinning – Hardwoods

Pre commercial thinning in hardwoods is carried out when the desired trees have reached six to nine meters and after some self pruning of the lower hardwood limbs has occurred.

Allows the selection of healthy preferred trees as crop trees; removes competing trees giving the crop trees room to grow; like carrots in a garden thinning greatly increases the diameter growth of the remaining crop trees.

Commercial Thinning

Poorer quality trees are removed leaving trees with better quality stems to grow and produce saw logs or veneer logs. Commercial thinning removes some merchantable volume from a stand.

Specialized Harvests

Specialized harvests can include shelter wood cuts, selection harvests, crop tree release, seed tree cut and others (see definitions). Harvests can be customized to meet the landowner’s needs.
