Transcript of BC stand-level C results

The greatest CO2 benefit of all the treatments studied came from replanting logged sites with genetically-improved seed rather than leaving them to natural regeneration. Treatment Undergrowth density Lessons learned Need to combine individual activities into practical treatment regimes.
Site-specific information needs to be considered in order to achieve modelling results in the real world.
Factor-in length of time C-sink established not just at one point in time.
Silvicultural impacts are quite small compared to large ecosystem C stocks

Timber volume <> C

Treatments may have negative or positive impacts

Earlier C-sink is better e.g. fertilization, rehab following natural disturbances.

Increased storage of C resulting from treatment can be maintained across a landscape.
