Intrductin This dcument is meant t be supprting material fr discussins related t frest cver stratificatin and milestne declaratins. These discussins are ccurring as a result f updates t the Frest Planning and Practices regulatin. This dcument fcuses n fur main tpics: The Plicy fr frest cver stratificatin The Plicy fr milestne declaratins The applicatin f thse Plicies, and Examples f the plicies in practice Appendix A cntains a cpy f the apprved amendments t the Regulatin. Plicy fr Stratificatin The unit fr declaratin f milestne events will remain the Standard Unit. Stratificatin is a tl that helps t measure the distributin f regeneratin within a Standards Unit. Issues assciated with stratificatin relate t stcking. The intent f this plicy is t supprt stcking which is well distributed acrss the SU while allwing flexibility t deal with specific cnditins r circumstances that result in a prtin f an SU being under stcked. Changes t the regulatin apply t areas under the FPC r as a default under FRPA. The default under FRPA wuld cver areas where stratificatin has nt been specifically cvered in the FSP. SUs under the FPC have been and will cntinue t be managed fr target levels as required by regulatin (FPC SPR s 11 and FPC THSPR s 40). Further, stcking levels established under FRPA are cnsidered t be f a high standard cnsistent with the apprval tests f the FPPR. This plicy assumes that the high standard f refrestatin currently undertaken in the prvince will cntinue. Examples f Stratificatin Within a standards unit, stratificatin and creatin f additinal frest cver plygns and assciated frest cver attributes must ccur: If there is a stratum that is belw the required minimum stcking standard at the regeneratin r free grwing time frames; Fr the purpse f FPPR s 86 within a standards unit, stratificatin and creatin f additinal frest cver plygns and assciated frest cver attributes shuld ccur, fr example: If there is mre than a 20% difference in leading species cmpsitin. Fr example Pl8Sx2 must be separated frm Pl5Sx5; If there is a switch in the leading species. Fr example Fdc8Cw2 must be separated frm Cw6Fdc4; If the species cmpsitin changes frm a mixed species stand t a pure stand. Fr example: Fdc10 must be separated frm Fdc6Hw2Cw2; If there is a stratum that has mre than 10,000 stems per hectare; If the site index based n the leading inventry species in adjacent strata have a change f mre than 3 metres; If crwn clsure changes by mre than 10%. Versin 1.4 1
Minimum Stratum Size Minimum stratum size is 1 ha. The intent is t nt cnsider lng tendrils r amrphus thin ameba-like units as being separate plygns, therefre: An understcked area is defined as an area where stcking levels are less than the minimum specified and is a minimum f 1 ha in size. An understcked area must be at least 20 m wide thrughut its length and at least 20 m frm the nearest understcked area. If it is less than 20 m frm the nearest understcked area they are cnsidered cntiguus. Milestnes This sectin highlights key pints related t Milestne Declaratins. Licensees may make declaratins that they have achieved milestnes under FRPA 107 nw including prvisins under FPPR 97.1 that the bligatin has been met t the extent that is practicable. Under the new FPPR 46.11(1), the bligatin assciated with that milestne must be achieved n every hectare within the standard unit. A licensee may declare (under 46.11(2)) that the bligatins in a standard unit have been met even if there are ne r mre patches that d nt meet the applicable standard as lng as The patches are less than 1ha (applicable t bth regen and FG milestnes) At free grwing, mappable patches between 1 and 2 hectares are als acceptable if the ttal area ccupied by the patches des nt exceed 5% f the Standard Unit area. Differences in requirements between Regen and Free Grwing Obligatins With the amendments t the FPPR there is a critical difference between meeting bligatins at regen delay and at free grwing. Essentially the regulatin will allw fr mre flexibility in meeting bligatin at the free grwing assessment as cmpared with the regeneratin assessment. Specifically: 46.11 (2) (a) is applicable t bligatins at bth the regen milestne and the free grwing milestne It indicates that at the time f assessment patches in the SU that d nt meet the bligatin are acceptable prviding they are less than 1 ha. 46.11 (2) (b) is applicable t the bligatins at the free grwing milestne nly It indicates that at the time f free grwing assessment, patches between 1 and 2 ha may exist and the bligatin will still be cnsidered t be met as lng as thse patches dn t exceed 5% f the area f the standard unit. Obligatins met t the extent that is practicable A new sectin has been added t the FPPR: s97.1 Declaratin: Obligatins met t the extent that is practicable If a stcking standard requirement is nt achieved but the bligatin hlder cnsiders that the bligatin has been met t the extent that is practicable they may submit a free grwing declaratin t the district manager which includes a statement f the extent t which the bligatin has nt been met, a statement that the persn did nt cntribute, in any manner, t nt meeting the requirement, and a ratinale f why it is nt practicable t fully meet the bligatin Versin 1.4 2
This declaratin may be made withut amending the applicable stcking standards fr the area. This sectin wrks in cmbinatin with sectin 46.11 Sectin 46.11 prvides flexibility within which the bligatin is, by definitin, fully met; Sectin 97.1 prvides that a persn may be relieved f an bligatin, even where it has nt been fully met. FPPR s 97.1 empwers the DM t reject a declaratin if satisfied that, having regard t the circumstances and cnditins applicable t the cutblck, it is in the public interest t cntinue t try t fully cmply with the free grwing requirement. It is incumbent n the DM t cnsider all factrs when determining if the standard has been met t the extent practicable and it is a benefit t sciety t cntinue t pursue refrestatin f the site, including grwth and yield implicatin n the standard unit r cutblck as a whle Practicable vs Practical Sectin 97.1 f FPPR uses the term practicable. This term is ften cnfused with the term practical. Practicable means that which might be dne, practiced, r accmplished; that which is feasible r perfrmable in the circumstances; r that which is actually pssible (e.g. capable f being carried ut ). Practical means that which might be dne cnsidering there is generally limited time, budget, resurces, and ther factrs (e.g. use in practice). The practical ptins wuld be a subset f the practicable ptins. Frm a hierarchical pint f view, if yu lk at all f the pssible slutins given unlimited time, budget, resurces, envirnmental cnditins, etc, nly a subset f all the slutins wuld be practicable. Similarly, nly a subset f the practicable slutins wuld be practical Applicatin f Stratificatin and Milestne Plicy As stated in sectin 46.11 (2) (b) f the Frest Planning and Practices Regulatin (FPPR) it may be acceptable t declare an SU free grwing with 1.0-2.0 ha f that SU carrying less stcking than the applicable stcking standard. Such a cnditin ccurs when the stcking standards are met fr the SU and when the area f lwer stcking is less than 5% f the standard unit. These ne t tw hectare types must be reprted as described in sectin 86 (3) (iii) f the FPPR. T satisfy this requirement, field persnnel will need t cllect and summarize silviculture and inventry data fr submissin. While nt a legal requirement, under existing apprved ministry survey prcedures, surveyrs wuld typically establish a five-plt minimum in a stratum. As it is nt the intent f these regulatry changes t prduce mre nerus prcedural requirements, it is suggested that surveyrs prduce a silviculture and inventry label based n either visual bservatin r any number f plts as determined necessary t prduce accurate results. Versin 1.4 3
Guidance n tracking within RESULTS The fllwing prvides interim prcedure n hw declaratins n these areas are t be reprted within RESULTS until a frmal prcess is develped in the next majr release. Declaratins are made int RESULTS n-line r via electrnic submissin (ESF). When applying s. 46.11 (2)(b) and s.97.1, cmments tied t a specific standard unit(s) may be submitted with the FG declaratin. We recmmend that a cmment statement such as Declaratin meeting requirement f FPPR s.46.11(2)(b) wuld cnfirm that the area nt meeting the stcking standards meets the tests as specified in the regulatin r Declaratin f bligatin met t the extent practicable as per FPPR s. 97.1 fr thse areas where the bligatin has nt met the requirements f FPPR s 46.11 but meets the tests f FPPR 97.1. The attached RESULTS milestnes screen is an illustratin f a successful ESF transmissin shwing bth the declaratin cmpnent & the cmment. Text cmments can be entered nline r via ESF and may accmpany the declaratin and cnfirm the applicatin f FPPR s.46.11 r FPPR s 97.1. Versin 1.4 4
