Coast Forest Region Research Section - Pedology (Soils)


 

About

Soil science is the science dealing with soil and its biota as a natural resource. It includes: soil descriptions for the biogeoclimatic ecosystem classification program; soil conservation from detrimental soil disturbances; soil ecology and the effect of stand management on soil biodiversity; soil and plant nutrition in even-aged and uneven-aged stands; non timber forest products such as mushrooms; and the management of soils for the sequestration of carbon. The overall objective of the programme is to conduct research to ensure that forest management practices do not compromise soil sustainability and adaptive capacity. The research pedologist works collaboratively with other members of the RCO research team and provincial counterparts to provide a scientific basis for forest management in the Region.

Marty's areas of interest are soil ecology (especially ectomycorrhiza), partial cutting, soil carbon storage, biodiversity conservation, and forest nutrition/productivity. He has published a number of papers on ectomycorrhiza fungal ecology and succession following disturbance. Marty is a member of the provincial soil science group undertaking studies on compaction and site organic matter removal (the Long-term Soil Productivity Study), as well as the Future Forests committee examining vulnerability to climate change. He has also been examining the interaction of light availability and tree nutrition on juvenile tree growth, biotic indicators of soil productivity, and soil issues concerning the management of hypermaritime forests. Marty has been involved with regional efforts to manage pine mushroom and golden chanterelle habitat and teaches workshops on mushroom identification for the public.
