• Testing Forest Vegetation Management Options.
  http://www.for.gov.bc.ca/hre/pubs/pubs/0118.htm
  Operational brushing programs in British Columbia have expanded rapidly over the past decade. In 1981 approximately 4000 ha were brushed in British Columbia. By 1989 this had increased to 60 000 ha. Current estimates suggest that between 25 and 30% of forest lands harvested in British Columbia will require vegetation management treatments. Treatments used involve the use of herbicides, the use of cutting and girdling tools, and, to a limited extent, the use of sheep browsing. In addition, site preparation treatments (prescribed burning, mechanical site preparation and herbicide treatments) were applied to more than 130 000 ha of crown forest land in British Columbia in 1992. Traditionally, vegetation management has been viewed in terms of specific treatments applied at one or two points in time. In many cases, foresters use their knowledge of autecology, competition, and responses in developing prescriptions that include strategies for avoiding problems through the use of appropriate site preparation t ...

• Field studies of seed biology.
  http://www.for.gov.bc.ca/hre/pubs/pubs/0184.htm
  Except in limited areas where there is enough advance regeneration, establishment of forest cover on harvested lands continues to depend on seedling planting programs or on natural regeneration by seeds. Whereas successful plantation programs depend primarily on plant competition and site variables at the time of planting, successful natural regeneration depends not only on the availability of seeds, but on favourable environmental conditions throughout the processes of seed production, dispersal, germination, and seedling establishment. Site preparation and other silvicultural treatments can improve the suitability of the seedbed and its micro-environment, but there is still much we do not understand about how various factors contribute to successful forest establishment. We have gained some insights, under controlled conditions, about the influence of major factors such as light and temperature, but we have limited experience with biological responses under actual conditions in the field. Anyone ...

• A comparison of mulch mat and herbicide treatments for reducing grass competition in the IDFww.
  http://www.for.gov.bc.ca/hre/pubs/pubs/0220.htm
  In the warm wet Interior Douglas-fir biogeoclimatic subzone (IDFww), mechanical and herbicide site preparation and brushing treatments have been used to establish planted conifers. These silviculture treatments have been prescribed to control grass and shrub competition which rapidly develops after harvesting. Many of these sites, especially those with a southern aspect, have experienced poor survival of planted Douglas-fir. Poor plantation establishment has been attributed to poor stock quality and severe grass and shrub competition for soil moisture. Innovative brushing methods are needed for the establishment of Douglas-fir on these dry sites. Herbicide and mulch mat treatments have been used with some success. Glyphosate herbicide has been widely applied in forestry as an effective vegetation control treatment. Hexazinone herbicide has also been used. Both herbicides have been shown to effectively control grass if applied while the grass is actively growing (Boyd et al. 1985; Fahlmann and Herring 1 ...
