This project was initiated to study competitive relationships between lodgepole pine (Pinus contorta) and trembling aspen (Populus tremuloides) and to provide operationally useful information about the management of mixed stands. In most cases, conifer timber production is the predominant goal for our forest plantations and the effects of broadleaf trees in these plantations are not well understood. A series of trials has been established to study the competitive effect of aspen on pine. Data collection and reporting on established long-term competition, and growth and yield studies in lodgepole pine-aspen stands has continued through 2004/05. In this fiscal year three field assessments were completed. One included re-assessing four pine-aspen stands that were 20 to 24 years old. The initial assessments were completed in 1992 and this last assessment which captures the growth over that last 12 years, will provide data on the long term effects from competing aspen on pine performance.
