CBST Impacts and Gaps

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 Chief Forester's Standards for Seed Use - that include provisions for the optional use of Climate Based Seed Transfer (CBST). Further area-based impact and gap analyses are planned upon the next release and the publication of the anticipated April 2020 amendments. 


CBST Seedlot Selection Tool

The CBST Seedlot Selection tool (hosted by Forsite Consultants Limited) supports the CBST Project with the testing and verification of the science foundation and in the development of policy, including support for impact and gap analyses, stakeholder engagement, and in the development of mitigation options. The CBST Seedlot Selection tool is updated to coincide with amendments to the Standards or Seed Use (e.g. changes to CBST Areas of Use)

Climate Comparison Tool

The CBST Climate Comparison tool (developed by Greg O'Neill, FLNRORD) provides users the ability to compare the climate space of a plantation ("I have a cutlock") or a seed source ("I have a Seedlot") under CBST with a climate space of interest (BEC variant entered by the user). The generated output allows users to compare any variances that may exist across a number of climate variables.

Impact and Gap Analysis Tools

The CBST Impact and Gap Analysis tools (Excel workbooks) provide users the ability to assess area-based impacts and gaps under CBST relative to Geographically Based Seed Transfer (GBST). Workbooks are updated based on publication of amendments to the Chief Forester's Standards for Seed Use (changes to CBST area of use). Seed and vegetative lots are refreshed approximately 1 to 2 times per year to align with those listed in the Seed Planning and Registry (SPAR) system. Filters include: include Species, Management Unit, Genetic Class, and Genetic Worth (GVO – growth and volume) filters to refine your queries.

CBST Impact Assessment and Gap Analysis (April, 2019)

Source Data and Supporting Information

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).

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).
