Abstract

Scientific data about the competitive effects of broadleaves on pine in young stands is required to assist policy and resource practitioners with relevant management decisions . Retrospective trials have provided data that was used to update the free growing guidelines for some of the IDF, SBPS and SBS subzones, but more information is needed to further refine existing guidelines and modify them for other biogeoclimatic subzones. Four long-term trials looking at pine aspen competition in the IDFxm, SBSdw1, and SBPSxc were previously established and are addressing these issues. Growth and performance of broadleaf trees, as well as conifers, needs to be explored because broadleaf trees are already providing an economic benefit that may increase over time. This data will also be used in tree growth models such as PrognosisBC to predict the growth of mixed species stands.
