FRPA Silvicultural Tests2 2: MOFR, 2006 FRPA Silvicultural Tests2 2: MOFR, 2006. An overview reference for the evaluation of stocking standards under FRPA. Test 1: Initial High level Coarse filter evaluation to determine if there are any obvious omissions or issues impeding FSP approval – does it cover the anticipated situations and circumstances (e.g., forest types, ecosystems, silviculture systems) to be encountered; can the proposed standards be measured to a reasonable level of precision and accuracy Test 4: Economically valuable supply of timber Species are valuable with respect to future options for products and values; maintenance or enhancement of a mix of species is considered a reasonable strategy; usually includes restrictions on acceptance of lower value species that can proliferate naturally (at stand or landscape scales) Test 2: Ecological Suitability Species are appropriate for the given BEC subzone/variant and site series and for the silvicultural systems applied Test 5: Consistency with the timber supply review The “set” of standards are linked to local assumptions for the sustainability of timber flows over time; does not preclude new standards that address emerging objectives, knowledge, science, or management challenges; standards could be rejected if they put projected timber flows at risk Test 3: Forest Health The regeneration date and stocking standards will result in the area being stocked with ecologically suitable tree species that address immediate and long-term forest health factors; includes landscape level concerns (e.g., over-deployment of one species)

Primary, Secondary & Tertiary Primary species Primary tree species are ecologically acceptable and have a high rating for silvicultural feasibility, reliability, and productivity under the average conditions for a site series. Primary species can be managed as a major component in a stand if the restrictions have been adequately addressed. Note: Primary species are not by default the preferred species. Species from any of the three categories can be chosen as preferred, if the species meets the identified management objectives and if restrictions can be dealt with through treatments. Secondary species Secondary species are ecologically acceptable, but rank lower than primary species for one or more of silvicultural feasibility, reliability, or productivity. Depending on the nature and extent of these limitations, secondary species can be managed as either a major or a minor component in a stand. Tertiary species Tertiary species are ecologically acceptable, but rank lower than primary or secondary species for one or more of silvicultural feasibility, reliability, or productivity. Depending on the nature of their limitations, on local conditions, and on management objectives, tertiary species are normally suitable only as a minor component within a stand. For example, tertiary species can be used as a minor component of all stands within an area. Evaluation Criteria Maximum sustainable productivity To satisfy the maximum sustainable productivity criterion, the relative productivity for each tree species, or combination of tree species, was evaluated to determine which were best suited to each ecosystem unit. Crop reliability To satisfy the crop reliability criterion, the relative susceptibility to natural hazards was evaluated for each tree species, to determine which species provide the most reliable choices for a future crop on a given site series. Established stands should be both resilient and resistant to all anticipated hazards, so that they will survive until harvest. Silvicultural feasibility To satisfy the criterion of silvicultural feasibility, ecologically viable tree species were evaluated, based on accumulated silvicultural experience, to determine whether they were able to produce sawlogs in a cost-effective manner on each site series within an acceptable rotation length. Preferred and Acceptable Preferred species Preferred species are ecologically suited to the site. Management activities are primarily aimed at establishing these species. The characteristics of these species are consistent with the desired timber and non-timber objectives for the site. Acceptable species Acceptable species are ecologically suited to the site, but management activities are not aimed at establishing them. The reasons for including a species labelled only as acceptable may be a higher-than-acceptable site limitation, such as pest risk, or a lower productivity than the preferred species. Special restrictions or limitations may apply to the use of these species.
