Alberta has been divided into 90 seed zones, 74 of which pertain to the Green Area. Seed zones are geographic subdivisions of Natural Regions and Subregions based on general genetic criteria. They limit seed movement to a conservation area where native trees of all species can be moved without risk of mal-adaptation or erosion of genetic integrity. Unrestricted Stream 1 seed collections from within a seed zone can be moved freely within that seed zone, but cannot be moved outside of the seed zone.
On a practical level, this means that tree seedlings to be planted in a specific seed zone must be grown from seed collected in that zone.

The movement (deployment) of seedlings outside the seed zone of origin may be allowed with a variance approval from Alberta Sustainable Resource Development. The decision allowing a variance will depend on the type of collection, ecological classification, provenance test results, climate transfer analyses and number of individuals being deployed. Boreal can assist the client to determine if a variance request is a viable option and with the application process.
