Permanent measurement plots (PMPs) for the collection of long-term growth and yield data are currently being installed on existing PROBE sites. The data will provide information about the effects of brushing on conifer growth and yield, stand dynamics, and plant community development. Measurements are scheduled to occur every 5 years to provide information that can be used to build or calibrate growth and yield models that take into account vegetation management treatments and adjust existing management guidelines. Information regarding broadleaf complexes is particularly important because of the long time period during which conifers and broadleaves interact, because of the controversy that currently exists regarding appropriate levels of broadleaves that can be retained at free-growing, and because these complexes grow in some of the most productive ecosystems in B.C. At present, we have installed PMPs on PROBE sites where the Mixed Broadleaf-Shrub, Aspen, and Dry Alder complexes are being studied.
