Description:
The purpose of this project is to determine (i) if green tree retention on harvested sites is a suitable management option for maintaining ‘healthy’ soil (in terms of maintenance of soil organisms and their associated functions), and (ii) what size and density of green tree retention patch is required for this purpose. The results will be used to revise guidelines for forest management practices to better protect the soil resource and preserve biodiversity. The effect of harvesting on soil organisms and associated functions is a critical knowledge gap that precludes certainty about the sustainability of current and proposed forestry practices. The decisive knowledge achieved through this research will allow BC forest managers to develop and use practices that are based on sound, defensible science and put BC at the forefront of forest research to support sustainable forest practices. B.C.’s Forest Practices Act, Canada’s National Forest Strategy and Canada’s Biodiversity Strategy all emphasize the importance of maintaining forest biological diversity, the ecological integrity of forests and ensuring sustainable use of forest resources. Current policies, regulations, and guidelines do not sufficiently consider the importance of soil organisms to the maintenance of ecological functions. This is largely because the scientific information does not yet exist to guide decision-making.
