Three Pillars
The FGC objective is for 75% of our planting material be obtained from orchard material by 2014
Lodgepole pine is the bottleneck
•The objective is for the average weighted Genetic Worth (GW) to be 20% by 2020 – on track
•GW is the expected gain in volume at rotation (i.e. GW 15 = 15% more wood volume at harvesting)
• also goals for genetic conservation, having adequate genecological information and supporting climate based seed transfer

Quality Assurance (QA) ProgramQA Foundations
Avoid Physical contamination (Debris) Avoid seedlot contamination (Adaptation) Information Management (Organization) Handling a perishable product (Care)
•Ensure seeds shipped to nurseries are of high quality
•Accumulate information on species MC ranges
•Compare standard lab results with SRQ results in seed preparation and at the nursery
