CBST Impact Assessment and Gap Analysis

Assessment of impacts, gaps, and opportunities for mitigation is a key component of Climate Based Seed Transfer (CBST) policy and implementation. The area-based CBST Impact and Gap Analysis work undertaken to date is based on the April, 2018 amendments to the Standards for Seed Use - optional use of CBST).  CBST Areas of Use are based, in part, on the provincial BEC map standard (BEC 10). Other baseline data includes transfer functions, migration distances, climate data, genetic suitability (coastal, 2029; interior, 2032), and species suitability (projected to 2030).

A set of tools to support the CBST Impact and Gap Analysis are now available for your use. Excel Workbooks (CBST Impact Assessment and CBST Seed Planning) also include Species, Management Unit, Genetic Class, and Genetic Worth (GVO – growth and volume) filters to refine your queries.

Provincial level reports and summaries are provided below for each species. Please note that this summary information represents a ‘snapshot’ of the current impacts and gaps identified under CBST (including seed deficits, surpluses, and orphans).  This information is expected to change as we move forward with implementation of policy options and business solutions (i.e. mitigation of gaps, new/re-aligned orchards and breeding programs).
