A large part of the energy that plants allocate to roots actually supports an intricate web of below ground, largely microscopic, life. In the interface between root and soil (the rhizosphere), interactions between roots, fungi, microarthropods and soil can improve or impair plant growth. Traditional commercial use of the forest of British Columbia has focused primarily on trees, especially trees of known economic value. As societal priorities have shifted and broadened to include many other forest uses and values, there has been an awakening to the diversity of life in our forests and to the impact that forest management has on other resources.
Our most important natural resource is the soil. Soil is a physical matrix, a chemical brewhouse. It is the biological community of soil about which the least is currently known because of the challenges of studying soil organisms in natural ecosystems. I am involved in the study of soil fungi and particularly mycorrhizal fungi from a variety of perspectives: the health of containerized nursery seedlings; the long-term impacts of soil compaction and organic matter removal; the ecology and management of commercially harvested wild mushrooms; the use of molecular tools to identify and detect the presence of fungal species on mycorrhizal roots (in collaboration with Mary Berbee).
