Climate change, impacts and adaptation scenarios : climate change and forest and range management in British Columbia by David Leslie Spittlehouse( )

9 editions published between 2007 and 2008 in English and held by 110 WorldCat member libraries worldwide

"This Technical Report is one of two foundation papers for the B.C. Ministry of Forest and Range (MoFR) Future Forest Ecosystems Initiative (FFEI). These papers will increase the awareness of the potential impact of climate change on forest and range resources in British Columbia. They will also provide information to aid in assessing the vulnerability of British Columbia's forest and range resources and their management, leading to the development of adaptation strategies for a changing climate. The FFEI was initiated by the Chief Forester with a symposium and workshop in December 2005. At the same time the MoFR Climate Change Task Team was preparing a report on how the MoFR should strategically position itself with respect to the potential impacts of climate change on the province's forest and range resources. The present report draws on the Task Team report, recommendations from the FFEI workshop, and numerous other documents including the most recent reports from the Intergovernmental Panel on Climate Change. It provides a summary of future possible climates for British Columbia, a brief review of possible impacts on forest and range resources, and options for and challenges to adapting to climate change. Finally, there are recommendations on how the MoFR might respond to climate change. The report contains four appendices that expand on material presented in the body of the report, including information on the past as well as on future climates of British Columbia.

The use of stumps for biomass in British Columbia : a problem analysis by Kirsten Hannam( )

4 editions published in 2012 in English and held by 79 WorldCat member libraries worldwide

"In British Columbia, stump removal was first tested in 1968 as a method of reducing the spread of root disease into regenerating stands (Morrison et al. 1988). Over the last few decades, stumping, as it is also known, has been practiced throughout the province in forests infected with the root disease fungi Armillaria ostoyae, Inonotus tomentosus, and Phellinus weirii (Sturrock 2000). Given the growing interest in bioenergy in the province (Province of British Columbia 2008), and the increasing popularity of stumps as a feedstock for bioenergy plants in Europe (e.g., Bjorheden 2006; Hakkila 2006), it is timely to consider the viability of using stumps as an energy source in British Columbia."
Growth and survival of Douglas-fir and western redcedar planted at different densities and species mixtures by Louise De Montigny( Book )

7 editions published between 2007 and 2015 in English and held by 55 WorldCat member libraries worldwide

"Survival and height, diameter at breast height (dbh), volume, and crown growth of Douglas-fir and western redcedar in a mixed plantation were measured 14 years after planting. As expected, Douglas-fir had faster early growth than western redcedar and average dbh, volume, and crown area of the stand increased as the proportion of Douglas-fir in the stand increased. However, the average growth of Douglas-fir and western redcedar was not significantly different when grown in a pure stand compared to being grown in a mixed stand. Average growth of either species was also not significantly different at densities of 500, 1000, or 2000 stems per hectare. Consequently, at this young age, the effect of the species mixtures on growth was likely due to different early growth rates rather than from differences between interspecific and intraspecific competition. This experiment will help to determine the long-term outcomes of different stand mixtures in producing timber volume."-- Web index page as viewed Oct. 15, 2007
The HyP³ Project : pattern, process and productivity in hypermaritime forests of coastal British Columbia : a synthesis of seven-year results( )

7 editions published in 2005 in English and held by 50 WorldCat member libraries worldwide

The HyP3 Project was initiated in 1997 to provide an integrated research approach to the study of pattern, process, and productivity in the hypermaritime forests of north coastal British Columbia. This report presents a synthesis of the project's 7-year results. It provides an overview of the project to date and summarizes initial results for each of the project components--hydrology and biogeochemistry, ecosystem processes, classification and inventory, and operational trials
An early history of the Research Branch, British Columbia Ministry of Forests and Range by Ralph Schmidt( Book )

4 editions published in 2006 in English and held by 50 WorldCat member libraries worldwide

Based on archival material and interviews with previous employees, this document traces the history of research within the B.C. Forest Service from 1912 to 1970. The B.C. Forest Branch 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). 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. 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

Effects of variable aspen retention on stand development, aspen sucker production and growth of lodgepole pine in the SBSdw1 variant of south-central British Columbia by T. A Newsome( Book )

6 editions published in 2006 in English and held by 48 WorldCat member libraries worldwide

Mixtures of trembling aspen (Populus tremuloides Michx.) and naturally regenerated or planted lodgepole pine (Pinus contorta var. latifolia Engelm. ex S. Wats.) occur throughout interior British Columbia. To develop effective management strategies for mixed stands where softwood timber production is the primary objective, silviculturists need information about levels of broadleaves that can be retained without seriously reducing conifer performance. They also require practical guidance on using this information to develop cost-effective treatment prescriptions. To address this topic in the Cariboo-Chilcotin, a pine-aspen competition project that includes studies in a variety of ecosystems is currently under way. In 1999, an operational trial to study the effects of variable aspen retention on stand-level lodgepole pine performance and aspen sucker production was established near McKinley Lake in the SBSdw1 variant of the Central Cariboo Forest District. The study was a co-operative undertaking by the B.C. Ministry of Forests and Weldwood of Canada, Ltd. In 2002, the study was adopted by the Silvicultural Systems Research Group of the Southern Interior Forest Region as part of the pine-aspen competition project, and objectives and methods were subsequently adapted to include the collection of long-term growth and yield and stand development data. This report summarizes fourth-year pine and aspen responses to aspen retention treatments, and provides baseline stand development information
Revisiting a forest extension strategy for British Columbia : a survey of natural resource practitioners and information providers by Shawn Morford( Book )

4 editions published in 2007 in English and held by 47 WorldCat member libraries worldwide

"Rapid and significant changes in British Columbia are greatly affecting the province's forest sector and are leading to an increased demand for reliable, science-based information. To help guide forestry extension programming in the province over the next 5 years, FORREX Forest Research Extension Partnership (FORREX) staff, in partnership with the Forest Investment Account - Forest Science Program, conducted a survey of clients, partners, and contacts. This web-based survey was designed to: (1) identify perceptions regarding the need for forestry extension in British Columbia; (2) characterize information gaps that exist within the forest sector; (3) identify barriers to the incorporation of new information; (4) evaluate information sources and forestry extension services; and (5) seek recommendations regarding the future of forestry extension. In August 205, a 26-question survey was e-mailed to 1368 potential respondents who were selected from the forrex client database. Using a stratified random sampling method, respondents were chosen from nine groups (academia, consultants, federal government, provincial government, First Nations government, major licensees, municipal government, non-government organizations, and "other"). A response rate of 22% was achieved with this survey instrument; the calculated maximum error was 5.4% at a 95% confidence level. All groups agreed that the need for extension services is greater now than it has been in the past 10 years. The greatest perceived barriers to incorporating science into management and decision-making were the lack of formal organizational processes, the profit focus of land managers, and the lack of time and funding to attend extension events. A majority indicated that extension should be paid by some ratio of public funds and cost recovery, although this ratio was not agreed upon. The operational community indicated a preference for accessible, concise information delivered in a timely fashion that does not require significant investments of time to absorb and incorporate. Overall, this survey showed that there is no "one size fits all" approach for forestry extension services. A goal of future extension could best be described in the succinct words of one respondent, "Keep it relevant and bring the newfound information to the user quickly."
Estimating historical variability of natural disturbances in British Columbia by Carmen Wong( Book )

4 editions published in 2003 in English and held by 47 WorldCat member libraries worldwide

Natural disturbances (mainly fire, but also such phenomena as landslides, catastrophic wind events, floods, and pest infestations) are an integral part of the processes shaping & maintaining forested landscapes in British Columbia. Part 1 of this report presents a concise review of natural disturbance dynamics for each of the 14 biogeoclimatic zones of the province, based on published & unpublished research specific to British Columbia and to similar ecosystems elsewhere. Gaps in research are identified. Part 2 describes 11 methods from the literature for determining intervals for stand-replacing & stand-maintaining disturbances. Information provided for each method includes the principle on which it is based, its strengths & weaknesses, and the type of data & assumptions required. A step-by-step guideline identifies one or more appropriate methods to select, prepare, use, & analyze available data with a focus on data available to timber supply reviews in British Columbia. Part 3 demonstrates an application of the process in part 2 for selecting & using one of the methods for determining disturbance intervals in the Arrow Forest District. The final part makes recommendations, based on the results of the first three parts, on addressing the gaps in research & on quantitative methods for determining disturbance intervals in British Columbia
Post-fire vegetation development and fire effects in the SBS zone : Haggen Creek, Francis Lake, Genevieve Lake, Brink and Indianpoint sites by Evelyn Hope Hamilton( Book )

6 editions published in 2007 in English and held by 46 WorldCat member libraries worldwide

"The effects of clearcutting and slashburning on vegetation and soil composition and structure were monitored at permanent plots in the Prince George Forest District for up to 10 years post-burn. Changes in floristic composition, percent cover, and height were documented and described for each study area. At each site, standard fire weather stations were used to determine fire weather codes and indices and predict forest floor moisture content. Woody fuel loading and consumption and burn severity were determined using a line-intercept approach in standard fire effects assessment triangles and circular plots. Forest floor consumption, mineral soil exposure, and woody fuel consumption were compared to values predicted by the Prescribed Fire Predictor." -- Ministry web index page as viewed Oct. 15, 2007
Natural regeneration of subalpine fir and Engelmann spruce in partially harvested high-elevation stands in east-central British Columbia by O. A Steen( Book )

6 editions published in 2008 in English and held by 46 WorldCat member libraries worldwide

"This study examines factors affecting natural restocking of small openings created by partial harvesting of high elevation (> 1500 m) Engelmann spruce (Picea engelmannii Parry ex Engelm.)-subalpine fir (Abies lasiocarpa [Hook.] Nutt.) stands in east-central British Columbia, Canada. We examined the effects of opening size (0.03, 0.13, and 1.0 ha), seedbed, and seed supply on density of post-logging regeneration for 10 years post-harvest. The effect of opening size on growth release of advance regeneration was also examined. Both seed production and seedbed limited densities of post-logging seedlings. Densities of subalpine fir and Engelmann spruce post-logging regeneration remained low at two sites where seedfall was low. Seedbed scarification significantly increased seedling densities where seed rain was high. In the absence of scarification, abundant seed production had little effect on post-logging seedling densities. Increased height and basal diameter growth of advance regeneration following logging was greater on 1.0-ha than 0.13-ha and 0.03-ha openings. This study demonstrates that post-logging natural regeneration in combination with advance regeneration can restock small openings in partially harvested stands where there is an adequate distribution of mineral soil seedbed and logging or site preparation coincide with or shortly precede a year of abundant seed production."
Vegetation development and fire effects at the Walker Creek site : comparison of forest floor and mineral soil plots by Evelyn Hope Hamilton( Book )

6 editions published in 2006 in English and held by 45 WorldCat member libraries worldwide

Slashburning has been widely used in British Columbia and some work has been done to improve the tools used to predict fire effects in cutblocks. This report provides information that can be used to guide the application of the most commonly used tools--the Canadian Forest Fire Weather Index System (CFFWIS) and Prescribed Fire Predictor (PFP)--in SBS cutblocks. The objectives of this study were: to quantify and describe changes in percent cover, height, species composition, and diversity of vegetation on forest floor and mineral soil substrates, for 10 years after burning in an SBSvk subzone site; to determine the relationship between actual fire effects (i.e., duff and woody fuel consumption and mineral soil exposure) and those predicted by the PFP; and to determine the relationship between predicted and actual duff moisture level when various conversion equations are used with the CFFWIS to predict duff moisture level
Dendroecology : a guide for using trees to date geomorphic and hydrological events by David J Wilford( Book )

5 editions published in 2005 in English and held by 45 WorldCat member libraries worldwide

"The study of tree response to environmental conditions is called dendroecology. This discipline can offer key advice to forest practitioners regarding when landslides or flooding have occurred in the past. When trees are tilted, buried, or scarred by events, or established on sediment following an event, a record is left in the tree rings. This guidebook provides forest practitioners with information and straightforward techniques for interpreting those records. The additional time and expense incurred is of minor importance compared to the information generated and the degree of confidence that can be placed in the identification of geomorphic and hydrologic hazards influencing a site."
Results and data from an ecological study of Garry Oak (Quercus garryana) ecosystems in southwestern British Columbia by Wayne R Erickson( Book )

6 editions published in 2008 in English and held by 45 WorldCat member libraries worldwide

"This report and CD consist of excerpts from my MSc thesis from 1996, covering the context for the study, results and survey data. In the thesis, I sampled the plant communities associated with Garry oak (Quercus garryana) in British Columbia to develop a classification for use in resource management. An overview is included here of a total of 43 plant communities. Descriptions have also been placed on the Web (Erickson 1998) and, with some modification, are presented in a field guide (Erickson and Meidinger 2007). A study of Garry oak ecosystems was compelling, given that they had been designated as critically imperiled in British Columbia. I used quantitative methods as well as subjective assessments to assemble a numerically adequate database, apply a landscape approach, and include wide geographic coverage. Although European phytosociology influenced some facets of my study, my classification is much more strongly related to other plant community research in the Pacific Northwest. I therefore placed the classification in a scientific context through objective comparisons with the level of differentiation from other studies throughout the Pacific Northwest. The 43 plant communities identified and described in the thesis are placed in a setting of scientific work through subjective comparisons with the literature on similar plant communities. Ecosystem relations of the plant communities are depicted from the collected field data, and supplemented with objective results at a broad level. Ecological hypotheses are suggested, along with management interpretations for each of the plant communities. In my thesis, preservation and active management are emphasized in a management strategy for Garry oak habitat as a whole."
Amabilis fir height-age and growth intercept models for British Columbia by Gordon Donald Nigh( Book )

4 editions published between 2009 and 2010 in English and held by 45 WorldCat member libraries worldwide

"The purpose of this project was to develop growth intercept and height-age models for amabilis fir (Abies amabilis Dougl. ex Forbes) on the coast of British Columbia. Twenty-eight stem analysis plots were established on Vancouver Island. These data were combined with data from 46 previously established stem analysis plots. The stem analysis data were converted into height-breast height age data and the site index was obtained from the data. A suite of 50 growth intercept models was developed, one model for each breast height age from one to 50. A height-age model based on the Hossfeld IV function was also developed. There were minor differences between the new height-age model and the height-age model currently in use. Therefore, implementation of the new height-age models should have minimal consequences on timber supply analyses and forest management decision making."--Abstract as viewed on Forest Science Program website, March 26, 2010
Microclimate studies in silvicultural systems on the Chilcotin Plateau of British Columbia : the Itcha-Ilgachuz Project (1997-2003) by Robert M Sagar( Book )

6 editions published in 2005 in English and held by 44 WorldCat member libraries worldwide

"Group selection and irregular group shelterwood silvicultural systems are being tested as options to conserve woodland caribou (Rangifer tarandus caribou) habitat. If successful, the systems will be applied within the very dry, cold Sub-Boreal Pine-Spruce (SBPSxc) and very dry, very cold Montane Spruce (MSxv) biogeoclimatic subzones, located on the high-elevation Chilcotin Plateau of west-central British Columbia. In these harsh growing environments, partial cutting strongly influences the microclimate in terms of air and soil temperature, frost events, and snow-free dates. To examine the magnitude of this influence, three pairs of climate stations were set up in partial cuts and clearcuts, across a range of elevations, to compare microclimate conditions. Over the 7-year sample period, all blocks had frequent and sometimes severe (air temperature <-4°C) frosts throughout the growing season. As many as 58 frosts (<0°C) out of 76 nights during the period 1 June-15 August were recorded at one block. Minimum air temperatures of -12.4°C in June and -10.5°C in July were recorded. Partial cuts substantially reduced the number and severity of frosts over clearcuts; however, soil temperature and soil temperature index (ST1) were lower in partial cuts than the nearby clearcuts. Mean growing-season (15 cm) soil temperatures were less than 10°C at all locations, with clearcuts being 1.5-1.9°C warmer than nearby partial cuts. Snow-free dates were approximately 1 month later at the highest-elevation site (1620 m) in comparison to the lowest site (1290 m). This lowered soil temperatures and shortened growing seasons at the highest site. Heavier snowpacks virtually eliminated soil freezing at the highest site. The study also compared north edge, centre, and south edge microsites within one 30-m opening on each of three partial cuts. The north edge (south aspect) was the most favourable microsite for seedling growth in the partial cuts, with the highest soil temperatures, earlier snow-free dates, and more solar irradiance. Low soil temperatures and light levels made the south edge (north aspect) the least favourable microsite. Group selection and irregular shelterwoods may be applied to 181 000 ha of northern caribou habitat. Results of this microclimate study show that partial cutting clearly modifies the growing environment for lichen, tree regeneration, mushrooms, and others species. The proposed systems show promise in their ability to maintain caribou habitat and allow for some timber harvesting."
The effects of site preparation and harvesting practices on planted seedling productivity and microenvironment in southern interior dry, grassy IDF forests by Jean Heineman( Book )

5 editions published in 2003 in English and held by 44 WorldCat member libraries worldwide

Dry, pinegrass-dominated sites in the interior Douglas fir (IDF) zone of southern interior British Columbia are challenging to regenerate, despite ongoing improvements in nursery & silviculture practices. Using results from three separate studies, this report discusses conifer seedling survival & growth responses to silvicultural systems & site preparation treatments that were applied to relieve harsh site conditions at Fehr Mountain, Murray Creek, and Opax Mountain. To help interpret these responses, the effects of silvicultural system & site preparation treatments on seedling microenvironment are also analyzed with reference to the following factors: soil water, air temperature, soil temperature, light, nutrient availability, soil physical properties, and ectomycorrhizae
Succession after slashburning in an Engelmann spruce-subalpine fir subzone variant : West Twin site by Evelyn Hope Hamilton( Book )

5 editions published in 2006 in English and held by 44 WorldCat member libraries worldwide

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 objectives of this study were to quantify and describe changes in percent cover, height, species composition, and diversity of vegetation following prescribed burning; to quantify and describe the growth and mortality of planted hybrid white spruce (Picea engelmannii x glauca) seedlings after prescribed burning; and to quantify site conditions, including fire weather and forest floor moisture content, and fire effects, such as forest floor and slash consumption, at the time of burning
