Changes to the Provincial Seed and Vegetative Material Transfer Guidelines (p. 21-31)

Interior seed planning zones (SPZ)

1. Western larch (Lw): Modify section 3.(p 25) to read: Transfer of Douglas-fir between SA and TOD, or between CT and QL not permitted. Transfer of western larch outside its native seed planning zone is permitted, irrespective of biogeoclimatic zones, but the transfer must adhere to the limits listed in Table 5.

Lodgepole pine superior provenances

2. Rocky Mt. Trench. Add TOD to the SPZs/Area of Use for the Rocky Mtn. Trench superior provenances (B+) source listed in Table 6 (p. 26).

Interior spruce superior provenances

3. Birch Island. Change the upper elevation limit for the Birch Island superior provenance to 1000 m, on Table 7 (p. 27). Note: this does not imply a 1000 m elevation transfer upwards from the seedlot’s source, but rather an elevation limit for the planting site.

Seed orchards

4. Coastal Douglas-fir (Fdc). Add to Table 9. (p 29) Fdc seed orchards: 101 (Quinsam), 114 (Koksilah), and 121 (Saanichton). All seedlots from these orchards may be used in the M and GL SPZ, and the lower limit of the Range of elevation use is 0 m. Upward transfer limit of +350 m, and latitude transfer of 3o N and 2o S, shall continue to be applied to the wt. mean elevation and latitude of each individual seedlot.

6. Lodgepole pine (Pli). Change the range of elevation use for Orchard 201 CP/FIN to 700-1200 m S of 56 degrees, and 700-1050 N of 56 degrees, and Orchard 202 CP/FIN to 570-1100 m S of 56, and 570 - 860 N of 56 on Table 10 (p.30). Also add NCH SPZ to the Seed Planning Zones for Orchard 218. on Table 10 (p.30).
