Herbicide applications are an important silvicultural tool in the regeneration of Canada’s forests. In 2009, herbicides were used to control competing vegetation on approximately 119,000 hectares of regenerating forests, largely in the provinces of Ontario, Alberta, and New Brunswick (Figure 1). Herbicides are a cost-effective, efficient and reliable tool that helps ensure plantation success. Their use is particularly important in retaining appropriate levels of conifer-dominated stands on the landscape. The Canadian forest industry relies on the judicious use of herbicides as one element of an integrated vegetation management program designed to ensure forest renewal, sustainable resource use, and to remain internationally competitive. The Federal government is involved in a number of aspects related to herbicide registration and research. The Pest Management Regulatory Agency of Health Canada reviews and regulates all pesticide use under the Pest Control Products Act, although provincial regulatory authorities may also impose further restrictions or guidelines on use. Prior to registration and use, each compound is subject to rigorous scientific review and testing with regard to potential effects on humans or the environment (Figure 2). Natural Resources Canada – Canadian Forest Service (CFS) carries out research that addresses specific issues related to forestry, with a particular focus on potential indirect effects on wildlife species or their habitat that might be detrimental to ecological integrity. CFS researchers have also been actively engaged in discovery and assessment of other nonchemical vegetation control methods, including biological control with native fungal organisms.
