Chief Forester’s Standards for Seed Use

The province's chief forester established the Chief Forester's Standards for Seed Use in accordance with the Forest and Range Practices Act and its regulations. These standards came into effect on April 1, 2005.

These standards require that seed used to establish a free growing stand on blocks subject to Forest and Range Practices Act must be registered, tested, and stored, with the ministry’s, Forest Improvement and Research Management Branch (Tree Seed Centre). Seed must meet specific collection, genetic diversity and physical quality requirements to be eligible for registration. Seed that has been genetically modified cannot be registered. Seed use standards also apply to seed collection (Collection Area), selection and use (Genetic Worth), and seed transfer (Areas of Use). Collectively, these standards maintain the identity, adaptability, diversity and productivity of the province's tree gene resources.
