Long-term Lodgepole Pine Silviculture Trials in Alberta History and Current Results

Long-term data from established field experiments are required to properly evaluate different silvicultural options and to provide the basis for development and validation of growth models. Such data are available from a series of thinning and fertilization field studies established between 1941 and 1984 in lodgepole pine stands in the foothills of Alberta. These field sites span a wide range of ecological conditions and geographic locations. This report describes the locations and site characteristics of these these studies, their establishment histories and objectives, their experimental designs and treatments, and their results up to 2005.
