How much biomass needed for ecosystems

Currently, BC forest managers are penalized if residual biomass after forest harvesting exceeds a given threshold. As noted in the proposed CFS study emergence of a bio-products industry has the potential to totally reverse this situation and force managers to leave enough to maintain ecosystem services. This would be a major change in BC forest management and public responses.  The retention of biomass is not new.  Foresters have learned from the European experiences that, if all the biomass is removed, soil productivity can decrease significantly. Also, BC studies in the 1990s identified the need for a given level of biomass. However, the results were not applied in policy. Even though this issue is not new, the CFS should be congratulated for initiating the study within the 2020 environment. Maintaining ecosystem productivity is critical to long-term forest stewardship and subsequently a significant contribution community resiliency.
