- Landscape Ecology and Natural Disturbances: Relationships to Biodiversity.
http://www.for.gov.bc.ca/hre/pubs/pubs/0154.htm
Natural disturbance statistics grab your attention: Hurricane-force winds flatten over 30 000 ha of forest land on northern Vancouver Island in the winter of 1906. Small isolated "hot spots" of mountain pine beetle infestations are detected in southwestern British Columbia in the early 1970s. These infestations irrupt rapidly a decade later into massive outbreaks cover-ing 460 000 ha of lodgepole pine forests. Wildfire burns over 348 000 ha of British Columbia's forest land in 1982. One fire alone covers 182 725 ha—more than half of the total area burned. These extraordinary events can mean different things to different people: a reduced timber harvest, a lost wilderness reserve, an unsightly recreation area. Many of the feelings generated embrace a sense of loss and the belief that nature is on the rampage. But while these scenarios may appear to conflict with and impair a multitude of forest resource values, these natural disturbances show evolution in action and can actually maint ...
- 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 ...

- Climate change: implications for the Boreal forest.
http://www.for.gov.bc.ca/hre/pubs/pubs/1124.htm
The findings of the recent IPPC Second Assessment Report conclude that the boreal forest is more sensitive and will be more affected by climate change than either temperate or tropical forests. Results suggest that over the next century in response to projected changes in temperature and moisture patterns the boreal ecosystem will undergo major changes in ecosystem boundaries, growth and natural disturbances related to fire and insects. This paper outlines the key highlights of the IPCC and more recent literature in terms of the effects of climate change for the boreal forest over the next 100 years. As well, the boreal forest appears to be responding to environmental changes that have occurred over the last century and more particularly over the last 30 years. Changes in boreal ecosystems related to the permafrost zone, vegetation productivity, disturbances related to fire and the carbon cycle have been noted. This paper reviews some of the major highlights of the changes that have been noted. Many of ...

- Thinning Lodgepole Pine in Southeastern British Columbia: 46-year Results.
http://www.for.gov.bc.ca/hre/pubs/pubs/1235.htm
The effects of thinning 53-year-old, fire-origin lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) are reported 46 years after treatment. Five thinning treatments plus unthinned controls were established in plots in the Montane Spruce biogeoclimatic zone in southeastern British Columbia. Although tree-size responses were substantial in relative terms, the absolute responses to thinning were small. On an area basis, the response to thinning can be substantial, particularly when the net periodic annual increment of the thinned plots is compared to that of the unthinned controls. During the 46-year observation period, the plots were attacked by mountain pine beetle (Dendroctonus ponderosae Hopkins), and the results of the study tend to support the theory that heavy thinning may help to beetle-proof lodgepole pine stands. ...
- Succession after Slashburning in an Engelmann Spruce-Subalpine Fir Subzone Variant: West Twin Site.
http://www.for.gov.bc.ca/hre/pubs/pubs/1384.htm
This study was undertaken to determine the successional development after a slashburn of known severity on an Engelmann Spruce-Subalpine Fir (ESSF) biogeoclimatic zone site. Herbaceous and shrubby vegetation composition, cover, and height were monitored along with the growth of planted spruce seedlings for 11 years in 30 permanent sample plots. Fire effects were determined using depth-of-burn pins to measure forest floor consumption and fuel assessment triangles to measure fuel loading and consumption following a microplot approach. Fire weather conditions were determined using standard methods outlined in the Canadian Forest Fire Weather Index System. The fire on this site was quite severe and consumed 52% of the organic layer. The consumption of such a high percentage of the forest floor favoured establishment of invasive species. Regrowth of some native forest species was quite slow. This may be attributable to the severity of the conditions on the site after burning (e.g., poorer in nutrients, more ...

- Fire Effects and Post-burn Vegetation Development in the Sub-Boreal Spruce Zone: Mackenzie (Windy Point) Site
http://www.for.gov.bc.ca/hre/pubs/pubs/1410.htm
The purpose of this study was to document fire effects and subsequent changes in vascular species composition and structure after a slashburn. Survival and growth of planted hybrid spruce seedlings were also monitored. The study site is a clearcut at Windy Point in the Mackenzie Forest District in the Sub-Boreal Spruce zone in northern British Columbia. Six permanent plots were established prior to burning and monitored for 10 years after the fire. Fire weather codes and indices were calculated, fuel loading and consumption were determined, and burn severity was measured at three fuel assessment triangles and in the vegetation plots. The slashburn was of low to moderate severity and consumed 22 % of the forest floor. Impacts were considerably less than those forecasted using the Prescribed Fire Predictor in conjunction with the Canadian Forest Fire Weather Index System, likely because the cutblock forest floor was wetter than predicted. Ten years after burning, the site was dominated by young p ...
- An Early History of the Research Branch, British Columbia Ministry of Forests and Range.
http://www.for.gov.bc.ca/hre/pubs/pubs/1413.htm
The B.C. Forest Branch (now Service) was created in February 1912 but research activities didn't begin until 1921 when James (Alex) Alexander studied timber utilization, logging slash disposal, natural regeneration, tree growth and yield, and fire protection. In 1923 Assistant Chief Forester Robert St. Clair recommended the establishment of forest experimental stations in the major forest types of the province, resulting in the Aleza Lake Experiment Station near Prince George (in 1924) and the Cowichan Lake Research Station on Vancouver Island (in 1929). The Research Division was formally established in 1927 with a staff of seven and annual expenditures of $34 000. The director was Percy Barr. By 1930 the Research Division of the B.C. Forest Branch was the largest and most active forest research organization in Canada. In the ensuing decades the research program went through many changes and evolved into a province-wide multi-disciplinary organization. Based on archival material and interviews ...
