Table 1. Changes to transfer limits – all origins

Table does not include natural stand species whose transfer limits did not change.

Lot Origin Species Code Common Name Seed and Vegetative Material Guidebook Chief Forester’s Standards for Seed Use
Natural Stands (BC) Ba Amabalis fir Transfer between Vancouver Island and mainland not permitted Guidebook p. 23 Transfer permitted. Appendix 3 of Standards
Fdi Interior Douglas-fir Transfer between SA and TOD and between CT and QL not permitted. Guidebook p. 25 Transfer permitted if used in same BGC zone of origin. Appendix 3 of Standards
Hw Western Hemlock Transfer between QCI and Vancouver Island to mainland not permitted. Guidebook p. 23 Transfer permitted, but QCI collections cannot be used N of 54 30 latitude on mainland. Appendix 3 of Standards
Pw Western white pine Unlimited elevation transfer in coastal SPZs +/- 700 m in all SPZs Appendix 3 of Standards
Yc Yellow-cedar No limit up in elevation in M SPZ
Update #7 		If collection elevation ≤ 1100 m, then +400 m/no limit down.
If collection elevation >1100 m, then +/- 300 m. Appendix 3 of Standards
Other Other Transfer between mainland and Vancouver Island not permitted. Restriction removed.
Superior Provenances All Refer to Tables 2-5 below Refer to Tables 2-5 below
BC Parent trees
(Seed orchard seed) 		All Transfer limits determined at time of registration. Additional restrictions for some orchard lots listed by orchard number Update #2 and Update #4 Transfer limits based on parent trees contributing to lot, and status of trees or lot (e.g. tested, untested or custom) s. 8.3, 8.5 and 8.6. of Standards If lot registered under Code, transfer in accordance with limits applied to lot at time of registration – or in accordance with applicable limits determined under CF Standards s. 8.10
Non-BC natural stands or parent trees
(exotic provenances) 		Natural stands Refer to Tables 6-7 below Refer to Tables 6-7 below
Ax Hybrid poplar Used in accordance with Ministry recommendations Update #2 Ax parent trees (i.e. clones) treated as tested parent trees. Transfer limits to be based on tested area of use for each tested parent tree.
Parent trees (seed orchards) Transfer limits determined at time of registration. Also, Idaho Pw use S of 52o latitude and 1450 m in elevation. Update #2 In accordance with limits specified in Table 6.2 of Standards
Other All May be used for operational trials if approved in silviculture prescription If species and source not listed in Tables 6.1 or 6.2, person may apply for alternative to the standards under section 43 of the Forest Planning and Practices Regulation. Confirmation of transfer limits for previously registered lots from non-identified sources pending.
