  rial was established to explore vegetation management options that may improve conifer survival and growth within the IDFww. The objectives of this study were to compare the effectiveness of the herbicides hexazinone and glyphosate and plastic mulch mat treatments for reducing grass competition and improving Douglas-fir seedling performance. Two separate experiments were established, representing dry and mesic environments within areas of homogenous terrain and vegetation. This extension note summarizes the five-year results from these two experiments. ...

• A comparison of manual brushing treatments in the ICHdw at Redfish Creek: 10-year results from blocks 10-13.
  http://www.for.gov.bc.ca/hre/pubs/pubs/0223.htm
  nd spring ungulate habitat, and can be important as a source of domestic water. As a result of these resource uses and public pressure, herbicides are rarely used for controlling competition to tree regeneration. The Redfish Creek Manual Brushing study was established in 1987 by Roger Whitehead of the Canadian Forest Service. The primary objectives of this research trial were to examine the cost effectiveness and productivity of motorized manual brushing treatments (Holmsen and Whitehead 1988) and to compare conifer and vegetation response to multiple motor-manual brushing treatments. This extension note summarizes the 1997 remeasurement of conifer and vegetation response data collected from blocks 10-13 (Figure 1). These blocks are adjacent to each other and provide a field demonstration of a range of brushing treatments. The objectives of the 1997 remeasurement were to compare brushing treatment vegetation, stocking, and conifer response 10 years after trial establishment. A more detailed report ...

• Effects of Thinning and Fertilizing Mixed Western Hemlock-Sitka Spruce Stands.
  http://www.for.gov.bc.ca/hre/pubs/pubs/0313.htm
  Limited information exists on the growth and yield of young mixed western hemlock (Tsuga heterophylla) and Sitka spruce (Picea sitchensis) stands on the Queen Charlotte Islands following pre-commercial thinning and fertilization. As a result, research into thinning and fertilization was initiated by the South Moresby Forest Replacement Account research committee. Our research project (Experimental Project [EP] 1097), conducted on Graham Island, investigates tree and stand growth responses to thinning and nitrogen and phosphorus fertilization in young Sitka spruce-western hemlock stands. In this extension note, we describe this project, present the 5-year response results taken from remeasurements after the 1996 growing season, and offer some preliminary conclusions. ...

• British Columbia Forest Service's Science Program: Science to support sustainability.
  http://www.for.gov.bc.ca/hre/pubs/pubs/1182.htm
  The prime mandate of the BC Forest Service's Forest Science Program is to bring scientific innovation to bear on sustainable forest management. For over 80 years, its staff has been an integral part of many significant changes to forest policies and practices. Decentralized researchers are in direct contact with local forest managers and resource users throughout the province, ensuring a focus on operationally relevant research as well as providing an accessible source of best available scientific knowledge to support policies and practices. Five core research activities within the program, including growth and yield, silviculture, forest genetics, ecology and earth sciences, yield valuable short and long-term information about how to sustain ecosystems, enhance timber production and manage forests for a variety of resource uses. In cooperation with partners and clients in universities, institutes, government agencies, the forest industry and others in both research and extension, program scientists and st ...
