The BC Long Term Soil Productivity (LTSP) study is part of a large, international network dedicated to testing sustainable forest soil management over the full timber rotation. Fully replicated LTSP sites have been installed in the interior of BC in 4 biogeoclimatic zones with 5 timber species and on 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 timber rotation. Findings from this research contribute to the development of our knowledge base and to ongoing development and refinement of forest practice regulations, guidelines, and effectiveness evaluation. The best fit for the LTSP among the funded themes for 05/06 is 3.1 in the Sustainability Program that addresses 'Indicators and monitoring systems’. The LTSP project results are used in the development and application of indicators, such as standards for soil disturbance and retention of woody debris, used in the FRPA soils value regulations and effectiveness evaluation.
