The PROBE (PRotocol for Operational Brushing Evaluations) project has gathered information about the effects of operational brushing treatments on conifer seedlings and vegetation in southern interior BC since 1991. Ongoing measurements on experimental sites provide information about the effects of brushing treatments on seedling establishment and growth, and are becoming increasingly valuable as the length of time since treatment increases. Ten-year post-treatment data is now being collected for several complexes ? long-term results are particularly important for broadleaf complexes that affect conifers for extended periods. Existing PROBE sites also have the potential to provide valuable long-term data about the effects of brushing on conifer growth and yield, stand dynamics, and plant community development and diversity. No long-term data of this nature currently exists in BC. Permanent Measurement Plots (PMPs) have now been established on a subset of existing PROBE sites where the Mixed Broadleaf-Shrub and Aspen complexes are being studied. Installation of additional PMPs to complete replication for brushing treatments that PROBE is studying in these broadleaf complexes will be done in 2004/05.
