Seed Planning Zone (SPZ) geometry is comprised of geographic areas of the province that are characterized by common ecological and genetic attributes for a given forest tree species. SPZ's are used for seedlot registration, seed planning, seed transfer and seedlot selection for reforestation. The geometry can be joined to the SEED_PLAN_ZONE table using SEED_PLAN_ZONE_ID to determine if the SPZ is for Genetic Class B (natural stand) or Genetic Class A (orchard/parent tree) and tree species.
