2 ObjectivesDescribe the process for amending the FDP to include stocking standards.Describe the content requirements for the stocking standards.Describe the link to the site plan.
3 Requirement for Stocking Standards in the FDP A person required to prepare the FDP for the area under a Site Plan must ensure that the FDP contains the stocking standards (Operational & Site Planning Reg 18.1(2) & 18.2 ) required for the Site PlanThe Operational & Site Planning Regulation lists stocking standard requirements for even-aged , uneven-aged and areas without regeneration objectivesAmendments to the FDP for stocking standards are exempt from the notice, review & comments provisions
4 Steps in Developing FDP Stocking Standards Prior to harvest a site plan is required unless a silviculture prescription is in effect for the areaA Site Plan cannot be prepared until FDP is amended and to include stocking standards and those standards are approvedSubmit FDP amendment for stocking standards on an FS 789 or equivalent
5 Steps in Developing FDP Stocking Standards - continued A complete set of stocking standards:is not required at the startcan be built up over timewill be an integral component of the future Forest Stewardship PlanIn the short term, amendment submissions may be required to establish approved stocking standards for specific cutblocks.
6 Steps in Developing FDP Stocking Standards (cont’d.) FDP amendments for stocking standards may be made forindividual cutblocksgroups of cutblocksthe entire FDP
7 Steps in Developing FDP Stocking Standards - continued Stocking standards can be developed that apply to more than 1 licence area. For example: standards can be developed collaboratively at the TSA levelDifferent standards can be developed for the same site series. For example: minimum stocking standards (MSS) or minimum inter-tree distance (MITD) may be different for a given site series on colluvial slopes
9 Forest Development Plan Stocking Standards FS789 The FS789 is an optional format for stocking standardsThe FS789 is a Shana electronic formThis form has some built in functionality to streamline the approval of stocking standardsThe software to use the form is available free of chargeTo access the FS789 form and to obtain information on Shana forms go to the following web address
10 A FDP will have an applicable set of stocking standards FDP standards are developed by RPF .DM reviews and if approved assigns a unique ID number
12 When approving stocking standards the district manager should choose from the following applicable set of numbers
13 Assigning Standards ID Numbers cont’d. The district manager assigns one ID number to each set of stocking standardsThe district manager may want to allocate a set of numbers to each licensee. For example: WeycoA set of stocking standards may apply to one ecosystem or to more than one ecosystemThere may be more than one set of standards for each ecosystem or group of ecosystems. This can allow for alternate standards where site conditions require different management. For example: forest health, visual, etc.The preferred and acceptable species may have conditions attached to their use. For example: not to comprise more than 20% of the well spaced trees within the standards unit SU
14 SITE PLAN STOCKINGSTANDARDSFor each standards unit a forester assigns the ID number of the appropriate stocking standards for the unit from the FDP
15 Stocking Standards - Even / Uneven Aged Stands Stocking standards is a generic term . For areas to be managed as even or uneven aged stands it includes:Stocking requirements as defined in Operational & Site Planning Regulation sec 18.1Regeneration DateEarliest Free Growing Assessment DateFree Growing Date
16 Stocking Requirements : Even -Aged Stands Minimum heightRequired height of the tree relative to competing vegetation in a 1 metre radiusOther performance standardsMinimum leave tree characteristics including form, health, vigourPreferred & acceptable speciesMinimum allowable horizontal distanceMinimum stocking standard (MSS) for preferred & acceptableMSS for preferredMaximum densityMaximum & minimum density post spacing
17 Stocking Requirements : Uneven-Aged Stands Leave tree standards for each layer of trees to be retainedPreferred & acceptable species to be retainedMinimum basal area & or minimum densityMinimum leave tree characteristics including form / health / vigourApplicable regeneration standardsOther performance standards necessary to produce and measure achievement of free growing
18 Stocking Standards for Areas Without Regeneration Objectives Preferred & acceptable species to be retainedMinimum basal area or minimum density to be retainedMinimum leave tree characteristics including form, health and vigour
19 Selection of Preferred & Acceptable Species The selection of preferred & acceptable species must be consistent with :any higher level plan for the areaestablishing a healthy ecological standcommercially valuableconsistent with current & future timber supplyIn general, preferred and acceptable species are selected from the primary and secondary species lists. In some cases, tertiary species also could be preferred
20 Selection of Preferred & Acceptable Species - continued Primary, secondary, and tertiary species were determined on the basis of a species’ productivity, reliability, and silvicultural feasibility based on:current knowledge of the productive capability of each site series (updated in 2000 to reflect SIBEC)the silvics of the tree speciesthe growth and development of existing second growth forests
21 Selection of Preferred & Acceptable - continued Primary species:are ecologically acceptablehave a high rating for silvicultural feasibility, reliability, and productivity under the average conditions for a site series.can be managed as a major component in a stand if the restrictions have been adequately addressed.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.
22 Selection of Preferred & Acceptable - continued Secondary species:are ecologically acceptablerank 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.
23 Selection of Preferred & Acceptable - continued Tertiary speciesare ecologically acceptablerank 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.
24 Selection of Preferred & Acceptable Species cont’d Preferred Species: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:Management activities are not aimed at establishmentThere 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 their use
25 Selection of Preferred & Acceptable Species - continued In determining the appropriate preferred and acceptable species, review the recommended species options for the site. Consider:• the desired stand structure• the timber & non-timber objectives for the area• the potential for natural regeneration• the role of advance regeneration
26 Selection of Preferred & Acceptable Species - continued • the hazards, such as pests, likely to affect the stand throughout the rotation• the feasibility of the treatments required to establish the stand under existing management constraints• the effect of the species or combination of species on the sitethe maintenance of biodiversity
27 Species Selection & landscape level objectives Several methods may be adopted in order to address landscape level objectives on a site-specific basis. Selecting a single species only for the minimum stocking standard preferred (MSSp) or selecting a minimum stocking standard for a species are both legitimate strategies in the right context.
28 Broadleaf SpeciesBroadleaf species should not be listed as preferred or acceptable where the objectives for broadleaf establishment or retention are:to provide a nurse crop,promote nutrient cycling, orfor general biodiversity objectives.It is anticipated that these objectives will be achieved through the free growing guidelines, which allow for a broadleaf component, but at a stocking level where the projected impact on conifer crop tree growth is acceptable
29 Broadleaf SpeciesBroadleaf species should only be listed as preferred or acceptable if deemed acceptable as a new forest crop as either pure broadleaf or mixedwood stands on the basis of:Broadleaf species are currently or will be included in the estimation of volume contributing to a management unit’s timber supplyLong term management objectives set out in a forest development plan (or in some instances a land use plan)Consistent with an explicit strategy that provides stated management objectives for broadleaves. These strategies should incorporate careful analysis of growth and yield implications and set out viable silviculture regimes that will achieve the management objectives
30 Broadleaf Species cont’d. Broadleaf species should only be listed as preferred or acceptable if deemed acceptable as a new forest crop as either pure broadleaf or mixedwood stands on the basis of:A short-rotation interim crop to manage for root rot centres. The use of hardwood cropping for this purpose is currently considered an operational trial and is not recommended for widespread use at this timeSubmission of FDP amendments listing broadleaf species as preferred may be appropriate where operational trials are to be established to manage for mixedwood or broadleaf stands (e.g., for enhanced production of high quality wood such as birch veneer)
31 Well SpacedThe provincial stocking standard guidelines were developed on the assumption of a 2 m minimum inter-tree spacing.While a 2 m minimum inter-tree spacing is suitable for most sites, a reduced inter-tree spacing may be appropriate for sites where plantable spots are limited by site characteristics, a site condition, or where clumpy stem distribution is a normal and desirable stand characteristic.
32 Examples of situations where a reduced minimum inter-tree spacing may be appropriate • hygric or wetter sites• very rocky sites• very harsh sites where protected microsites are critical (e.g., shade, snow creep)• areas with a high potential for cattle congregation• sites with a significant number of large wildlife trees (e.g., 50 uniformly distributed trees/ha)• riparian areas with a high residual component• sites where a stump avoidance strategy is employed to manage root rot• cluster planting (e.g., grizzly bear habitat)• partial cut areas with an abundance of residual regeneration.
