• Forest management and climate change.
  http://www.for.gov.bc.ca/hre/pubs/pubs/0186.htm
  : A clear definition the problem, that is, the level of change at which action is needed. The determination of the sensitivity of forest organisms to a changing climate. The development of management responses to be implemented when the changes occur, and implementation of actions needed now. Monitoring of forests to assess if and when changes are occurring. Disturbances of forests, such as harvesting and forest fires, provide opportunities for forests to adjust to the changing climate. The success of adjustment will depend on factors such as the sensitivity of species to climate change and the availability of alternate species. We may be capable of aiding managed forest and commercial tree species to adjust to a changing climate; however, in parks and wilderness areas we will probably have to 'let nature take its course'. Forest management already addresses many of the problems, such as fire, disease, insects and reforestation failures, that are will occur under a changed climate; it is the location a ...

• 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 ...

• 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
  After harvesting, sites in the Interior Cedar-Hemlock Dry Warm subzone (ICHdw) frequently regenerate to rich, brush-dominated communities that can inhibit successful conifer establishment. Species common to these post-harvested areas include: paper birch (Betula papyrifera Marsh.), Douglas maple (Acer glabrum Torr. var. douglasii [Hook.] Dipp.), redstem ceanothus (Ceanothus sanguineus Pursh), beaked hazelnut (Corylus cornuta Marsh.), ocean spray (Holodiscus discolor (Pursh) Maxim.), common snowberry (Symphoricarpos albus [L.] Blake), thimbleberry (Rubus parviflorus Nutt.), and fireweed (Epilobium angustifolium L.). Located on the lower valley slopes of southeastern British Columbia, the ICHdw subzone also features other important land uses that make forest management complex and controversial. In addition to being the most diverse subzone in the province in terms of tree species (Braumandl and Curran 1992), this subzone often provides critical winter ...

• Assessment of the Condition of Small Fish-bearing Streams in the Central Interior
  http://www.for.gov.bc.ca/hre/pubs/pubs/1237.htm
  Plateau of British Columbia in Response to Riparian Practices Implemented under the Forest Practices Code. The condition of small fish bearing streams (Forest Practices Code class S4) in the central interior of British Columbia was assessed to determine the effects of riparian forest harvest practices implemented under the B.C. Forest Practices Code. The purpose of the survey was to determine: How frequently are the different types of streamside harvesting practices implemented? Do the different types of streamside harvesting practices meet the objectives of the Riparian Management Area Guidebook? and Do the different types of streamside harvesting practices result in apparent impacts to fish habitat? The survey investigated the extent of forest harvesting potentially affecting small fish-bearing streams, the prevalent riparian silviculture treatments and levels of tree retention, the evidence for stream channel disturbance after forest harvesting, the degree of shade loss over the s ...

• Silviculture Treatments for Ecosystem Management in the Sayward (STEMS): Establishment Report for STEMS 1, Snowden Demonstration Forest
  http://www.for.gov.bc.ca/hre/pubs/pubs/1336.htm
  Douglas-fir Young-Growth Production Forests" in the Capitol Forest near Olympia, Washington, developed jointly by the managers of the Washington State Department of Natural Resources and the scientists of the Pacific Northwest Research Station. The decision to replicate the treatments in the Sayward Forest was based on the similarity of knowledge gaps in the Sayward Forest and the Capitol Forest and because replication in Washington and British Columbia results in greater statistical power and ability to extrapolate over a wide geographic area. This technical report describes the establishment of the first replication of STEMS in 2001 in the Snowden Demonstration Forest. Ongoing studies include: Tree growth and stand development, including understory vegetation Regeneration and light availability Windthrow, mortality, and coarse woody debris recruitment Harvesting production and impacts of residual tree damage and soil disturbance (in partnership with the Forest Engineering and Re ...
