Abstract
In 1988, FERIC monitored two precommercial thinning operations in British Columbia: one in a coastal western hemlock stand and the other in an interior lodgepole pine stand. Both operations included side-by-side comparisons of chain saws and clearing saw. FERIC established pretreatment plots to assess stand composition and density conducted productivity assessments, and evaluated port-treatment results.

Abstract
In a study funded under FRDA, FERIC AND PFC established research plots for the silvicultural assessment of a vegetation-management trial in Nelson. FERIC conducted productivity assessments of three cutting attachments for Husqvarna clearing saws; the Maxi 200, Multi 300, and Multi 255-4. Pretreatment vegetation and port-treatment seedling damage were examined by PFC researchers. This report summarizes the first-year results. Follow-up revegetation and crop growth response will be monitored and reported by PFC.

Abstract
In 1989, four single-stem, vegetation-control methods were used on trembling aspen overstory on two study sites, at Prince George and Kelowna North British Columbia. The study compared cost and productivity of four treatments: hack-and squirt, gel cap, EZJect, and girdling. The study also established permanent sample plots and collected baseline data for monitoring the efficacy of treatments and the effect of the treatments on understory plant communities. The project was funded by the federal direct delivery component of the Canada/BC Forest Resource Development Agreement (FRDA).

Abstract
En 1987, FERIC a observé un projet de lutte contre la végétation concurrente prè de Grande Prairie, Alberta. Les équipes du service forestier utilisaient des débroussailleuses Husqvarna 165RX pour couper les tiges feuillues dans une plantation d'épinette blanche de six ans. Le projet comprenait des études de productivité, de même que des évaluations après traitement.

Abstract
FERIC monitored a mechanical vegetation control project near Fort Vermilion, Alberta. Agricultural mowers, under contract to the Alberta Forest Service, were used to cut the aspen overstory in a young spruce plantation. FERIC established pretreatment vegetation-assessment plots, conducted productivity assessments, and evaluated posttreatment results.

Abstract
A study funded by Forest Resource Development Agreement (FRDA), FERIC, and FORINTEK Canada Corp. examined the potential for thinning and utilizing 40- to 70-year-old lodgepole pine stands in British Columbia. This study included a review of literature pertaining to the thinning of lodgepole pine, and investigation of thinning activities in British Columbia, a survey of processing and marketing opportunities for this resource, and a productivity study of partial cutting in lodgepole pine. This report summarizes the results and provides recommendations for managing and utilizing this resource. The study took place in late 1989.
