Abstract
A study by the British Columbia Ministry of Forests (BCMOF), Fraser Lake Sawmills (of West Fraser Mills Ltd.), and the Forest Engineering Research Institute of Canada (FERIC) compared at-the-stump and roadside processing of stems. FERIC determined the productivity and costs of the two harvesting systems and five subsequent regeneration regimes. The impacts of these treatments on slash distribution, cone distribution, mineral soil exposure, site distrubance, and plantable spots were also examined.

Abstract
A commercial thinning study in mule deer winter range was performed in the interior of British Columbia. The commercial thinning was followed by a pre-commercial thinning operation to create a clumpy, multi-storied stand with gaps for regeneration. The Forest Engineering Research Institute of Canada (FERIC) monitored the commercial thinning and pre-commercial thinning operations and determined the costs and productivities of these phases.

Abstract
A multi-agency trial was established to determine the impacts of commercial thinning on the growth, yield, and development of white spruce stands. The commercial thinning operation was completed using a Timberjack 1270 harvester and a Timberjack 1210B forwarder. The Forest Engineering Research Institute of Canada (FERIC) monitored the harvesting phase, determined the operational cost and productivity of the harvester and forwarder, determined the residual tree damage, and evaluated the effectiveness of a brushing crew in increasing the productivity of the harvester in areas with high densities of non-merchantable trees.

Abstract
Mistik Management Ltd. has been using a Meri Crusher mounted on a small loader since 1998 to prepare sites for planting. The Meri Crusher mulches the organic material and mixes the mulched material with mineral soil to create a mixed microsite to favour planted white spruce and provide vegetation control from Calamagrostis canadensis (marsh reed grass) and aspen. However, harvesting in aspen and mixedwood forests creates moderate to high slash loading. When the Meri Crusher is used for site preparation, these slash loadings have led to low machine productivity.
