Seed Planning Zone MVW is a materialized view of SEED_PLAN_ZONE_GEOMETRY polygons joined with the SEED_PLAN_ZONE table. The materialized view displays the spatial polygons for each Seed Planning Zone (SPZ) for Genetic Class=B (natural stands, all species) and Genetic Class=A (seed orchards, each tree species has specific SPZ geometry). SPZs are areas of the province that are characterized by common ecological and genetic attributes for a given forest tree species.
