Silvicultural system

General objective

  • To ensure that the appropriate silvicultural system is applied to the area under the prescription.

General requirements

A silviculture prescription must describe the silvicultural system to be used.

Specific requirements

Post-harvest stand descriptions

For all silvicultural systems, the desired post-harvest stand structure and site condition must be stated in the prescription, as well as the species and function of trees to be left standing. Additional stand structure and composition goals must also be described, including either the basal area per hectare or density per hectare for:

For commercial thinning, harvesting of poles, sanitation treatments, and other intermediate cuttings that do not have regeneration objectives, the species and function of trees to be left standing to satisfy non-timber resource objectives must be stated. This information may also be provided under the section for specific management strategies, in the applicable sub-section(s).

Group selection

The prescription must provide a description of the range and approximate average of opening sizes.

Single tree selection

The prescription must provide a description of the planned residual basal area per hectare.

Commercial thinnings and other intermediate cuttings

The prescription must state, where applicable, that it is prepared specifically for:

In such cases, the prescription does not need to describe the silvicultural system, whether livestock grazing will be used for vegetation management, the regeneration date, or the free growing assessment period.

Although there is no requirement for a regeneration date or free growing assessment period, a survey must be completed more than 12 months after the completion of harvest. Section 26 of the Silviculture Practices Regulation describes the requirements of the report for this survey, which include: the identification of the area under the prescription, any applicable tenure information, the NAR, the BEC, forest health information, complete inventory label(s), and the number of acceptable and preferred trees per hectare.
