Abstract

In BC, LTSP sites have been installed with 4 biogeoclimatic zones, 5 timber species, and calcareous or non-calcareous soils. Throughout North America, there are 62 similar installations, all designed to investigate the impacts of soil disturbance on near-term and long-term soil and forest productivity. Plots have had three levels of compaction (none, intermediate and heavy) and three levels of organic matter removal (stem only harvest; whole tree harvest; forest floor removal and whole tree harvest) before being regenerated with commercial tree species. Measurement of soil properties, understory vegetation, microclimate, and tree productivity occur at scheduled periods throughout the full rotation. Findings from this research contribute to the development of our knowledge base and to ongoing development of forest practice regulations and guidelines.
