Abstract
In 2000, the Canadian Ecology Centre Forestry Research Partnership (CEC-FRP) initiated two side-byside experiments aimed at quantifying the effects of woody and herbaceous vegetation on white pine (Pinus strobus L.) establishment, growth, and stem quality. The first experiment was established subsequent to a clearcut harvest near Reynolds Lake, in the McConnell Lakes area of Northeastern Ontario, and is intended to represent the restoration of white pine to sites that have become dominated by other, less desirable species. White pine seedlings were planted and treatments initiated on this site in 2001. The second experiment was established subsequent to a shelterwood harvest in a stand adjacent to the first site, and is intended to represent conventional regeneration efforts where white pine are well represented in parent stands. White pine seedlings were planted and treatments initiated on this site in 2002. Through the support of the Spray Efficacy Research Group (SERG), J.D. Irving Limited, and the Canadian Forest Service-Atlantic, a third experiment was established subsequent to a shelterwood harvest near Doaktown, New Brunswick. Having somewhat different soils and management regimes, this third installation is intended to compliment the two Ontario studies and broaden experimental inferences.
The following document summarizes the research activities and preliminary results of these studies to date. This document is intended to be a supplement to the fact sheets, available on the Partnership website at http://forestresearch.canadianecology.ca, which detail objectives, experimental design, and methods for these two studies.
