Goal One: Foster Resilient Forests
The desired outcome for Goal One of the B.C. Forest Stewardship Action Plan for Climate Change Adaptation includes:
Forests that are well adapted to the full amplitude of both current and future climatic conditions.
Complex and diverse forest ecosystems and landscapes that are resilient to climate change impacts and other stressors.
Feature: Climate Based Seed Transfer
Climate change is expected to result in trees in most regions of British Columbia becoming increasingly maladapted to the climates in which they are growing. Consequently, planting seedlings adapted to future climates (assisted migration) is recognized as a key strategy to address climate change, as it will help maintain healthy, productive forests, and ensure capture of gains obtained from decades of selective breeding. Climate Based Seed Transfer (CBST) is a climate change adaptation initiative and key action that will transition B.C. to a seed transfer policy framework and system that is climate-based. In the interim, changes are being made to existing policy and standards, where appropriate.
B.C.’s proactive policy for adaptation includes:
New seed transfer standards provide for the limited range and population expansion of Western Larch beyond its contemporary range (historical and current climate envelope) in areas projected to be climatically suitable in the year 2030. Chief Forester’s Standards for Seed Use (June 2010 amendment) – Assisted Range and Population Expansion of Western Larch.
“To date, an estimated 267 thousand seedlings (Seed Planning and Registry System; Sowing Year 2011) have been requested to take advantage of this limited Western larch range expansion climate change adaptation opportunity.” - Tree Improvement Branch
Changes to natural stand and orchard upward elevation transfer limits (100 – 200m) of most species have been made to seedlots registered on the Seed Planning and Registry (SPAR) system. Chief Forester’s Standards for Seed Use (Nov 2008 amendment) – Climate Based Upward Elevation Changes.
