Over the past 4 years, seven permanent sample plots (1 ha each) have been established in select sites throughout the ESSF to monitor and study attack dynamics and impact of western balsam bark beetle, Dryocoetes confusus. Annual assessment of these plots will enable us to better understand host selection and outbreak dynamics of this insect. Information collected from these plots includes spatial arrangement of all trees (live, dead, beetle attacked, blowdown), growth and yield data, attack information, levels of mortality and blowdown and other site information. Data collected from this study will assist in making biological and economic stand management decisions in similarly impacted ESSF stands. This data set will become part of a much broader, encompassing study that will benefit other areas that are impacted by the western balsam bark beetle.
