In 1996 we initiated a study to evaluate several techniques for measuring light under broadleaf canopies. Hourly average photosynthetic photon flux density and percent transmittance were measured 1 m above the ground at four points in each of three canopy densities created by a spacing experiment in a 35-year-old paper birch (Betula papyrifera Marsh.) dominated stand located near Prince George, B.C. At each point, fisheye photographs were taken and LAI-2000 plant canopy analyzer (LAI-2000), spherical densiometer, and competition index (Lorimer'sindex) measurements were made. Percent transmittance measurements onan overcast day (1-h average), transmittance measured over periods of 3 h or longer on a clear day, LAI-2000 diffuse noninterceptance measurements, and gap light index determined from fisheye photographs were strongly correlated with growing season percent transmittance (r2>= 0.96) as was competition index (r2 = 0.928). Concave spherical densiometer measurements and midday percent transmittance measurements on clear days were also well correlated with measured percent transmittance (r2>= 0.89). Estimates of understory light by the LITE model were strongly correlated with growing season percent transmittance. Correlations improved with increasing length of the period simulated (r2 = 0.755 for a point measurement on a clear day; r2 = 0.936 for an entire sunny day;and, r2 = 0.953 for the entire growing season). However, this version of the model underestimated percent transmittance in these spaced birch stands by 34-90%. [ABSTRACT FROM AUTHOR]

Abstract: Postfire tree species compositions are predicted to be the same prior to fire according to the direct regeneration hypothesis (DRH). We studied 94 upland boreal forest stands between 5 and 18 years after fire in Ontario, Canada. Postfire species-specific regeneration density was positively related to prefire stand basal area for Pinus banksiana, Populus spp., Betula papyrifera and Picea mariana, but not for Picea glauca and Abies balsamea. In addition, seedling density of Populus spp., B. papyrifera, P. mariana, P. glauca and A. balsamea were positively affected by build up index and, except Populus spp., their density increased with age of burn. To facilitate testing the DRH, we introduced a term called compositional difference (CD) that is the difference in a species relative percentage between the postfire and prefire stand. The testable null hypothesis is CD=0 for a given species. CD was not different from 0 for P. banksiana, was 19.8% for Populus spp., 10.4% for B. papyrifera, −17.9% for P. mariana, −14.6% for P. glauca, and −14.9% for A. balsamea, indicating fire increases broadleaves at the expenses of mid- and late-successional coniferous species. Compositional increases of Populus spp. and B. papyrifera in postfire stands occurred mostly where these species were a minor component prior to fire. In conclusion, the DRH was supported by the specific positive relationships between postfire regeneration densities and prefire basal area for P. banksiana, Populus spp., B. papyrifera and P. mariana. However, if the DRH is used for predicting postfire composition, P. banksiana is the only species that had the same composition between postfire and prefire stands. Nevertheless, CD for P. banksiana was negatively related to its prefire composition. Similarly, CD for other species was negatively related to their prefire compositions with varying effects of build up index and age of burn. Our results suggest, if fire occurrences increase with global change, the boreal landscape will be more dominated by hardwoods and mixtures of conifers and hardwoods. [Copyright &y& Elsevier]

Canada has 347 million ha of forest cover, contributing to the potential large availability of wood‐based resources. Although Canada's forest sector contributed $23.7 billion to the national nominal gross domestic product (GDP) in 2019, the GDP contribution of the wood product manufacturing subsector shrank by 6%. To reposition the Canadian forest industry, new forest management practices and wood‐based conversion technologies should be applied. In this context, the use of woody biomass in biorefineries to produce clean energy, fuels, and chemicals is becoming increasingly significant. There is a need to understand the current status and challenges of the wood‐based biomass conversion technologies that have been and are being developed in Canada. This information will help decision‐makers in formulating and implementing forest sector‐related policies for a sustainable bioeconomy in Canada. This study is focused on a review of Canadian woody biomass conversion technologies. Our critical review identified considerable potential biomass conversion technologies specialized for woody feedstock, all in the Canadian setting. We focused on the prospects of revitalizing Canada's pulp and paper industry through the integration of pre‐treatment processes and biochemical technologies. The thermochemical conversion pathway was identified as the dominant route for woody feedstock valorization. The review also identified pathways with the potential to diversify the existing product mix that generate products from wood streams, such as chemicals and biomaterials. Most of the biochemical and thermochemical research done in institutional and multi‐institutional research collaborations from laboratory scale to industrial scale will boost the chances of the commercialization of a wood‐based biorefinery in Canada.

With climate change, climatic optima are shifting poleward more rapidly than tree migration processes, resulting in a mismatch between species distributions and bioclimatic envelopes. Temperate hardwood tree species may take advantage of the release of climate constraints and forest management to migrate into the boreal forest. Here, we use the SORTIE‐ND forest simulation model to determine the potential for the persistence of three temperate species (sugar maple, red maple and yellow birch) when introduced at seedling stage in typical balsam fir–paper birch (BF–PB) bioclimatic domain stands of eastern Canada, quantifying the consequences on the native species composition. SORTIE‐ND is a spatially explicit, individual‐based forest stand model that simulates tree growth, regeneration and mortality. We performed a novel parameterization of the SORTIE‐ND tree growth equation allowing for the inclusion of climate modifiers on tree growth. After validating our model with data from permanent forest inventory plots, we modeled the dynamics of unharvested stands at different successional stages, as well as post‐harvest stands, after the addition of sugar maple, red maple and yellow birch seedlings at different densities. Our results show that current BF–PB domain climate conditions do not limit growth and survival of temperate species in boreal stands. Of the temperate species introduced, sugar maple had the lowest ability to grow and survive by the end of the simulation. Species assemblages of host stands were impacted by the presence of temperate species when the addition of seedlings was above 5000 temperate seedlings per hectare at the beginning of the simulation. For stands that were recently clear cut, temperate seedlings were unable to grow due to intense competition from aspen regeneration. Our results suggest that both current climate and competitive interactions between temperate species and boreal species should not impede the ability of temperate species to grow and survive in the BF–PB domain.

Aim: Seedling recruitment is a vital process for forest regeneration and is influenced by various factors such as stand composition, climate, and soil disturbance. We conducted a long‐term field experiment (18 years) to study the effects of these factors and their interactions on seedling recruitment. Location: Our study focused on five main species in boreal mixed woods of eastern Canada: trembling aspen (Populus tremuloides), paper birch (Betula papyrifera), white spruce (Picea glauca), balsam fir (Abies balsamea), and white cedar (Thuja occidentalis). Methods: Sixteen 1‐m2 seedling monitoring subplots were set up in each of seven stands originating from different wildfires (fire years ranging from 1760 to 1944), with a soil scarification treatment applied to every other subplot. Annual new seedling counts were related to growing‐season climate (mean temperature, growing degree days and drought code), scarification, and stand effects via a Bayesian generalized linear mixed model. Results: Soil scarification had a large positive effect on seedling recruitment for three species (aspen, birch and spruce). As expected, high mean temperatures during the seed production period (two years prior to seedling emergence) increased seedling recruitment for all species but aspen. Contrary to other studies, we did not find a positive effect of dry conditions during the seed production period. Furthermore, high values of growing degree days suppressed conifer seedling recruitment. Except for white cedar, basal area was weakly correlated with seedling abundance, suggesting a small number of reproductive individuals is sufficient to saturate seedling recruitment. Conclusion: Our findings underscore the importance of considering multiple factors, such as soil disturbance, climate, and stand composition, as well as their effects on different life stages when developing effective forest management strategies to promote regeneration in boreal mixed‐wood ecosystems.

The article describes the development of the web-based Canadian Forest Service climate change indicator system, referred to as the Forest Change Tracking System. This indicator system was established in 2011 with financial support from the Adaptation theme of the Government of Canada Clean Air Agenda. The objectives of the Forest Change Tracking System are to (a) raise awareness and inform on the occurrence and scope of ongoing changes across Canadian forests associated with climate change and to (b) support the inclusion of adaptation into forest management planning and forest-related policies. The development strategy was to focus on a limited number of most relevant indicators and to build on existing capacity in order to produce information on current and future climate change impacts across Canada's vast forests. An initial list of 141 potential indicators relevant to forestry was compiled through a series of workshops with more than 100 researchers and forest sector stakeholders and through a global scan of climate change indicator initiatives. A rating system based on each indicator's potential relevance, sensitivity, and feasibility of measurement was used to select a subset of 35 indicators. These indicators fall within three broad systems—climate, forest, and human. Each indicator web page contains information on the relevance of the indicator, graphs, or maps on past trends and future projections across Canada and related links and references. This paper also presents lessons learned, discusses challenges and opportunities, and reviews potential next steps related to the broadening of this indicator system. [ABSTRACT FROM AUTHOR]

The rapid development of new digital technologies for natural resource management has created a need to design and update governance regimes for effective and transparent generation, sharing and use of digital natural resource data. In this paper, we contribute to this novel area of investigation from the perspective of institutional change. We develop a conceptual framework to analyze how emerging natural resource data governance is shaped by related natural resource governance; complex, multilevel systems of actors, institutions and their interplay. We apply this framework to study forest data governance and its roots in forest governance in Finland and Canada. In Finland, an emphasis on open forest data and the associated legal reform represents the instutionalization of a mixed open data-bioeconomy discourse, pushed by higher-level institutional requirements towards greater openness and shaped by changing actor dynamics in relation to diverse forest values. In Canada, a strong institutional lock-in around public-private partnerships in forest management has engendered an approach that is based on voluntary data sharing agreements and fragmented data management, conforming with the entrenched interests of autonomous sub-national actors and thus extending the path-dependence of forest governance to forest data governance. We conclude by proposing how the framework could be further developed and tested to help explain which factors condition the formation of natural resource data institutions and subsequently the (re-)distribution of benefits they govern. Transparent and efficient data approaches can be enabled only if the analysis of data institutions is given equal attention to the technological development of data solutions. • We studied how emerging forest data governance is shaped by dynamics in forest governance. • Forest data institutions may support path-dependency or renewal of forest governance, depending on context. • Innovative data institutions may enable a dynamic governance continuum from closed to open natural resource data. • Future studies should focus on feedback effects of data governance on natural resource governance.

Despite a large literature that addresses the gendered structure of forestry occupations in Europe and the USA, relatively little attention has been paid to these issues in Canada. In this paper, it is argued that policy makers and academics have used outdated statistics about forestry employment to shape policies and programs of government and industry. Use of these data has been to the general disadvantage of women working in the forest industry and in forestry communities. This paper draws mainly on three studies, spanning the mid-1990s to the mid-2000s. Each study relied on secondary sources such as Census data, government and industry documents, as well as primary sources such as interviews or questionnaires. On Vancouver Island, British Columbia, analysis of land reallocation policies and transition strategies for displaced workers in the 1990s did not consider women as forestry workers or consider how job losses and opportunities for retraining might vary between men and women. Consequently, gender-neutral transition strategies were more accessible for men than for women. A study of female forestry workers in Saskatchewan revealed there was very little knowledge about employment conditions for women in forestry. Women reported that they missed out on training and advancement opportunities because they lacked networks, childcare support or other benefits that might encourage them to improve their circumstances. Finally, a survey of forest sector advisory committees across the country revealed a very low rate of participation by women, even though those who did participate had some significantly different viewpoints about forestry than their male counterparts. In combination, these efforts suggest that improvements in the understanding of forestry employment would benefit forestry workers, both male and female, and ensure that all workers made lasting contributions to the industry.

Climate change interacts with ecological processes leading to changes in tree and forest growth rate, biome shifts and species composition, all of which are influenced by disturbances. This study explores future overarching climate trends of eight of Canada's ecozones containing managed forests. For the 2071 to 2100 period, climate projections indicate a warming trend of up to an additional 5.5 °C and an overall increase in annual precipitation. Future trends suggest marked contrast between coastal and interior forests and polarization between western and eastern forests. Warmer temperatures, accumulating degree-days above 5 °C and frost-free days suggest longer and drier growing seasons and greater risk of drought particularly in moisture-limited areas such as montane cordillera, taiga shield and boreal shield ecozones. Warmer temperatures and rising precipitation combined with less snow suggest shorter and wetter future winters. This indicates greater risk of rain-on-snow and freeze-thaw events, flooding and landslides particularly in coastal ecozones. We discuss how these projections are likely to result in shifts in dominant species and abundance, which when coupled with the cumulative effects of future disturbances, is likely to alter future forest dynamics and impact harvestable wood volumes for Canada's forestry industry.

Assessing a territory’s fire proneness is fundamental when planning and undertaking effective forest protection and land management. Accurate methods to estimate the risk of fire ignition in natural environments have been proposed over the last decades and digital mapping has been used to identify critical areas. The Canadian Forest Fire Weather Index is a well-known fire danger rating index created and improved during the last 45 years by the Canadian Forest Service. The goal of this paper is twofold. Firstly, we evaluated whether the Forest Fire Weather Index is an adequate instrument to predict fire ignition in Alpine and sub-Alpine areas using quite a large dataset of meteorological and forest fire data collected in the Lombardy region (Northern Italy) between 2003 and 2011. By means of a spatial binary regression model, we demonstrated that Forest Fire Weather Index has a significant impact on the probability of fire ignition. Since this approach allows us to account for other characteristics of the territory in order to provide a more accurate estimate of the spatial wildfire dynamics at a moderately large scale, the second goal of the paper aims at creating a model to assess fire risk occurrence using the Forest Fire Weather Index and land use information. It has been found that ignition can easily occur in large forested areas whereas denser urban areas are less exposed to fire since they usually have no fuels to ignite. Nevertheless, since human activity has a direct impact on fire ignition human presence, it fosters ignition in forested areas. Finally, the model, including these spatial dimensions, has been employed to derive a probability map of fire occurrences at 1.5 km resolution, which is a fundamental instrument to develop optimal prevention and risk management policy plans for the decision maker.

Climate change is a likely addition to the unpredictable challenges urban communities will face. Enhancing urban forests has gained prominence as a climate adaptation tool in cities. The fact that urban forests are also vulnerable is now starting to emerge. Many urban forest management professionals do not know how to take climate change into account and what aspects of urban forest vulnerability to climate change to prioritize. Bringing climate change to the forefront of the decision-making process in urban forest management, and urban forests to the forefront of urban climate issues, is important to urban forest success. This paper presents an exploratory assessment of vulnerability to climate change in the Canadian urban forests of Halifax, London, and Saskatoon. The objectives of the assessment were to: 1) identify the elements of urban forest exposure and sensitivity to climate change, the nature of the expected impact, and the adaptive capacities that exist in these three urban forests; 2) assess which of these elements contributes more to urban forest vulnerability to climate change; and, 3) elicit adaptive strategies based on this information. The method used was participatory and expert-based and allowed for a systematic evaluation of vulnerability. Exposures related to drought, heat stress, and wind, susceptibility of urban trees to insects and diseases, and the sensitivity of young trees and tree species with specific temperature and moisture requirements, are the main concerns regarding the vulnerability of urban forests to climate change in these three cities.

Air temperature (Ta) is an important climatological variable for forest research and management. Due to the low density and uneven distribution of weather stations, traditional ground-based observations cannot accurately capture the spatial distribution ofTa, especially in mountainous areas with complex terrain and high local variability. In this paper, the daily maximumTain British Columbia, Canada was estimated by satellite remote sensing. Aqua MODIS (Moderate Resolution Imaging Spectroradiometer) data and meteorological data for the summer period (June to August) from 2003 to 2012 were collected to estimateTa. Nine environmental variables (land surface temperature (LST), normalized difference vegetation index (NDVI), modified normalized difference water index (MNDWI), latitude, longitude, distance to ocean, altitude, albedo, and solar radiation) were selected as predictors. Analysis of the relationship between observedTaand spatially averaged remotely sensed LST indicated that 7 × 7 pixel size was the optimal window size for statistical models estimatingTafrom MODIS data. Two statistical methods (linear regression and random forest) were used to estimate maximumTa, and their performances were validated with station-by-station cross-validation. Results indicated that the random forest model achieved better accuracy (mean absolute error, MAE = 2.02°C,R2 = 0.74) than the linear regression model (MAE = 2.41°C,R2 = 0.64). Based on the random forest model at 7 × 7 pixel size, daily maximumTaat a resolution of 1 km in British Columbia in the summer of 2003–2012 was derived, and the spatial distribution of summerTain this area was discussed. The satisfactory results suggest that this modelling approach is appropriate for estimating air temperature in mountainous regions with complex terrain. [ABSTRACT FROM AUTHOR]

Climate change poses a serious risk to sustainable forest management, particularly in boreal forests where natural disturbances have been projected to become more severe. In three Quebec boreal forest management units, biomass carbon storage under various climate change and management scenarios was projected over 300 years (2010–2310) with a process-based dynamic landscape model (PnET-succession for Landis-II). Several strategies varying in their use of partial cuts and clear cuts, including business as usual (BAU) (clear-cut applied on more than 95% of the managed area), were tested and compared to conservation scenarios (no-harvest). Based on simulation results at the landscape scale, the clearcut-based scenarios such as BAU could result in a decrease of biomass carbon stock by 10 tC ha−1 yr−1 compared to the natural scenario. However, this reduction in carbon stock could be offset in the long term through changes in composition, as clearcut systems promote the expansion of trembling aspen and white birch. In contrast, the use of strategies based on partial cuts on more than 75% or 50% of the managed area was closer to or better than the natural scenario and resulted in greater coniferous cover retention. These strategies seemed to be the best to maximize and stabilize biomass carbon storage and ensure wood supply under different climate change scenarios, yet they would require further access and appropriate infrastructure. Furthermore, these strategies could maintain species compositions and age structures similar to natural scenarios, and thus may consequently help achieve forest ecosystem-based management targets. This study presents promising strategies to guide sustainable forest management in Eastern Canada in the context of climate change. [ABSTRACT FROM AUTHOR]

Loss of forest cover and derived effects on forest ecosystems services has led to the establishment of land management policies and forest monitoring systems, and consequently to the demand for accurate and multitemporal data on forest extent and structure. In recent years, spaceborne Light Detection and Ranging (LiDAR) missions, such as the Global Ecosystem Dynamics Investigation (GEDI) instrument, have facilitated the repeated acquisition of data on the vertical structure of vegetation. In this study, we designed an approach incorporating GEDI and airborne LiDAR data, in addition to detailed forestry inventory data, for estimating tree-growth dynamics for the Laurentides wildlife reserve in Canada. We estimated an average tree-growth rate of 0.32 ± 0.23 (SD) m/year for the study site and evaluated our results against field data and a time series of NDVI from Landsat images. The results are in agreement with expected patterns in tree-growth rates related to tree species and forest stand age, and the produced dataset is able to track disturbance events resulting in the loss of canopy height. Our study demonstrates the benefits of using spaceborne-LiDAR data for extending the temporal coverage of forestry inventories and highlights the ability of GEDI data for detecting changes in forests' vertical structure.

Information about post-disturbance regeneration success and successional dynamics is critical to predict forest ecosystem resistance and resilience to disturbances and climate change. Our objective was to identify and classify post-disturbance empirical research conducted by the Canadian Forest Service (CFS) of Natural Resources Canada and their collaborators to provide guidance on future research needs, improving our understanding of post-disturbance recovery in a Canadian context. To achieve our objective, we collected and classified peer-reviewed and non-published literature produced by the CFS between 1998 and 2020 that concerned post-disturbance ecology. We focused on research addressing natural or anthropogenic disturbances, such as wildfires, pest outbreaks, windthrows, forest management, seismic lines, and those that studied processes related to soil, vegetation, fauna, hydrology, and microbial communities. We found that forest harvesting was the disturbance most studied by CFS between 1998 and 2020, followed by fire. Despite the fact that large, forested areas are affected annually by pests, studies on recovery after pest outbreaks were scarce. Other disturbances, such as mining and seismic lines or other abiotic disturbances were rare in CFS literature. Most studies (70%) examined changes in vegetation related to forest management and fire and they were mainly focussed on post-disturbance tree regeneration success. Post-disturbance changes in understory species diversity were also well-studied. Our results provide a geographic overview of CFS research on post-disturbance recovery in Canada and enable the identification of key knowledge gaps. Notably, research focusing on recovery after natural disturbances was underrepresented in the assessed literature compared to studies centered around harvesting. Long-term research sites, chronosequences that substitute space for time, and studies focused on consecutive disturbances are especially important to maintain and establish sustainable forest management strategies in the face of climate change.

The objective of this study was to develop spatiotemporal whole-stem wood quality prediction models for a suite of end-product-based fibre attribute determinates for jack pine (Pinus banksiana Lamb.) and red pine (Pinus resinosa Aiton): specifically, for wood density (Wd), microfibril angle (Ma), modulus of elasticity (Me), fibre coarseness (Co), tracheid wall thickness (Wt), tracheid radial diameter (Dr), tracheid tangential diameter (Dt), and specific surface area (Sa). Procedurally, these attributes were determined for each annual ring within pith-to-bark xylem sequences extracted from 610 jack pine and 223 red pine cross-sectional disks positioned throughout the main stem of 61 jack pine and 54 red pine sample trees growing within even-aged monospecific stands in central Canada. Deploying a block cross-validation-like approach in order to reduce serial data dependency and enable predictive performance assessments, species-specific calibration and validation data subsets consisting of cumulative moving average values were systematically generated from the 27,820 jack pine and 11,291 red pine attribute-specific annual ring values. Graphical, correlation, regression and validation analyses were used to specify, parameterize and assess the predictive performance of tertiary-level (ring-disk-tree) hierarchical mixed-effects whole-stem equations for each attribute by species. As a result, the jack pine equations explained 46, 66, 74, 63, 59, 72, 42 and 48% of the variation in Wd, Ma, Me, Co, Wt, Dr, Dt and Sa, respectively. The red pine equations explained slightly higher levels of variation except for Me: 50, 71, 31, 83, 72, 78, 56 and 71% of the variation in Wd, Ma, Me, Co, Wt, Dr, Dt and Sa, respectively. Graphical assessments and statistical metrics related to attribute and species-specific residual error patterns and goodness-of-fit, lack-of-fit and predictive error metrics, revealed an absence of systematic bias, misspecification or aberrant predictive performance. Consequently, the resultant parameterized models were acknowledged as acceptable functional descriptors of the intrinsic spatiotemporal cumulative developmental patterns of the studied end-product fibre attribute determinates, for these two pine species. Although predicted development patterns were similar between the species with the greatest degree of nonlinearity occurring before a cambial age of approximately 30 years, irrespective of attribute, jack pine exhibited a greater degree of nonlinearity in the Wd and Dt developmental trajectories, whereas red pine exhibited a greater degree of nonlinearity in the Ma, Me, Co, Wt, Dr and Sa developmental trajectories. Potential biomechanical linkages underlying the observed attribute distribution patterns, as well as the potential utility of the models in forest management, are also discussed.

Stakeholder participation is a vital component of successful Strategic Environmental Assessment (SEA). SEA, an evaluation of environmental and sustainability consequences of strategic initiatives prior to their implementation, seeks to ensure that various stakeholder perspectives are considered early in the strategic decision-making process. However, once the implementation decisions are taken, are the stakeholders consulted with, or involved in, strategy implementation and SEA follow-up? If so, how can participatory processes benefit delivery of strategies and follow-up? These questions remain largely unexplored due to the conventional focus on ex ante SEA and limited knowledge about SEA follow-up. This paper explores the role and potential of stakeholder participation processes in facilitating SEA follow-up in the case of a 20-year Pasquia-Porcupine Forest Management Plan (FMP), in Saskatchewan (Canada). It explores different forms of stakeholder participation in the FMP and SEA follow-up implementation and identifies the associated benefits for SEA follow-up. [ABSTRACT FROM PUBLISHER]

Reconciling diverse forest values within policy and decision-making processes is an ongoing challenge in forestry. The use of environmental impact assessment (EIA) provides potential for improving forest management and making it more responsive to diverse interests. This paper examines EIA in Canadian and Finnish forest planning. In Finland there has been a reluctance to see EIA as a tool for forest planning while in Canada some provinces have long applied EIA to forest management. Ontario, Canada, provides one example of applying EIA to forest planning at a range of scales in order to advance integrated planning and help conflict management. The paper provides a brief analysis of the Finnish forest planning system, an illustration of the Ontario EIA forest management experience, and then considers the application of EIA to Finnish forest management. The paper concludes that EIA may be workable for Finnish state forests and would likely enhance planning and management, but given the existing institutional frameworks EIA would be difficult to apply to private forests.

This paper examines the social capital that evolved in the Sustainable Forest Management Network (SFMN), one of the Canadian Networks of Centres of Excellence. Our longitudinal study shows a sevenfold increase in the total number of researchers and a high density of relationships among (researchers from) provinces across the country. The results of a social network analysis revealed that 52.6 percent of the network researchers maintained the same number of collaborators while 46.7 percent increased their number of collaborators enormously: the maximum increase in number of collaborators being 6900 percent and the minimum 6 percent. A bibliometric analysis suggested that the number of publications was strongly correlated to measures of social capital. From a science and innovation policy perspective, the finding that more than half of the researchers in the SFMN did not increase their personal networks of collaborators raises important questions. A theoretical model is proposed to examine whether funding agencies should focus on fostering various network structures and evolutions or rely on competition in the distribution of research funds through networks. The proposed model is designed to measure the impact of various network structures on the development of social capital and research output. [ABSTRACT FROM PUBLISHER]

How do processes for community engagement in forestry decision making in Canada serve the aims of sustainable forest management? This paper reports on several studies of forest land-use and management planning processes in four provinces and a national survey of forest-sector advisory committees to determine who is selected to participate, what values participants bring to the table, and how participants are expected to behave in committee processes. The analysis suggests that participatory mechanisms are both shaped by and reinforce local norms, values and expectations of forestry communities. Thus, the focus is on understanding the social context within which communities become engaged rather than providing a technical assessment of specific initiatives. In particular, the study examines assumptions related to gender, class and racialized identities that operate in rural communities and shape the participation and influence of participants. These studies all suggest that forestry advisory committees remain elite organizations, dominated by individuals with economic stakes, constrained by priorities set by government and/or industry, and focused on technical issues. Women, Aboriginal people and those of lower socioeconomic status are less likely to participate and less likely to make substantive contributions when they do participate. Differences by gender are significant, but gender is not the only factor that explains the marginalization of some groups within these processes. The results suggest a need to examine how gender intersects with other sets of social relations such as class and racialized identity in order to better understand the social factors that will influence the achievement of sustainable forest management.

Aerial application of herbicides continues to be a dominant method of vegetation control in Canadian forest management. In this paper, we describe a suite of relatively modern technologies and emphasize their potential for integrated use in optimization of aerial herbicide treatments. The potential is illustrated using several case studies involving fixed-wing applications of glyphosate-based herbicide in the boreal forest region of Ontario, Canada. Results indicate that integration of geographic information systems, differential global positioning, electronic-guidance, on-site meteorological monitoring and remote sensing can be used to effectively plan, enhance application control and provide detailed post-treatment assessment and archival data for herbicide spray programs. SprayAdvisor, a GIS-based decision support system with the capacity to directly integrate all of these elements is briefly described. [ABSTRACT FROM AUTHOR]

The development of cooperation depends on the nature of deliberations among and between local stakeholders and the state as well as the context of deliberations, especially whether larger scale governance helps, hinders or overrides deliberative processes. However, the context of deliberations has not been a focus of past research on deliberation. The paper identifies the key context criteria that influenced deliberation and the development of cooperation in a comparative case study of two forest advisory committees in Ontario, Canada. The study uses cognitive mapping and network analysis techniques to identify key context criteria and concludes with five inferences regarding the influence of context on deliberation and cooperation that have implications for deliberation and decentralization theories.

An increasing number of sustainability standards integrate the principle of free, prior and informed consent (FPIC) as a requirement to ensure respect for the rights of Indigenous peoples. FPIC remains a contested norm, due in part to divergences of interpretation and gaps in implementation. Drawing on a typology based on FPIC conceptions, this paper presents a comparative analysis of the Forest Stewardship Council's (FSC) standard development processes in three countries, Canada, Russia and Sweden. The paper investigates the dynamics of designing FPIC requirements and conceptions of FPIC reflected in national standards. Drawing on semi-structured interviews and analysis of written standards, this study finds similarities in terms of the key debates, such as the scope of Indigenous authority and applicability of FPIC to non-Indigenous communities, however underscored by different stakeholder dynamics and outcomes. Despite the structuring presence of International Generic Indicators, different conceptions of FPIC are reflected in national standards. • We develop a typology of FPIC conceptions including: human rights, relational and procedural. • Analysis of FSC standard development processes in Canada, Russia, Sweden reveal divergent views of FPIC between chambers. • Articulations of FPIC in national standards tend toward relational (Canada) and procedural (Russia and Sweden) conceptions.

Recent interest in sustainable forest management planning in the Yukon has coincided with growing public awareness of climate change, providing an opportunity to explore how forestry plans are incorporating climate change. In this paper, the Strategic Forest Management Plans for the Champagne and Aishihik First Nations Traditional Territory (CATT) and the Teslin Tlingit Traditional Territory (TTTT) are examined for evidence of adaptation to climate change. For each plan, management policies and practices that are also recognized as ways to adapt to climate change are identified to provide information on the incremental costs and benefits of additional adaptation efforts. A typology for classifying sustainable forest management plans according to how they address climate change is proposed and applied to the CATT and TTTT plans. This typology, which may be useful to any future retrospective assessments on how successful these or other sustainable forest management plans have been in addressing and managing the risks posed by climate change, consists of a matrix that categorizes plans into one of four types; (1) proactive-direct, (2) proactive-indirect, (3) reactive-direct, and (4) reactive-indirect. Neither of the plans available for the southern Yukon explicitly identifies climate change vulnerabilities and actions that will be taken to reduce those vulnerabilities and manage risks. However, both plans have incorporated some examples of 'best management practices' for sustainable forest management that are also consistent with appropriate climate adaptation responses. Even in a jurisdiction facing rapid ecological changes driven by climate change, where there is a relatively high level of awareness of climate change and its implications, forestry planning processes have yet to grapple directly with the risks that climate change may pose to the ability of forest managers to achieve the stated goals and objectives of sustainable forest management plans.

The term “aboriginal forestry” is used increasingly to describe the evolving role of First Nations peoples in Canadian forestry over the last 30 years. This paper reviews a diversity of experiences and identifies issues that have important implications for governments, forest planners, and First Nations: a forestry regime that reflects the interests of governments and industry rather than those of First Nations; variable implementation of aboriginal rights in forestry practice; benefits and problems of economic partnerships; limitations on consultation, traditional knowledge, and comanagement in forestry; and finally, different forestry paradigms. Among these experiences and issues, we recognise different visions for the participation of First Nations peoples in Canadian forestry. At one end of the spectrum, “forestry excluding First Nations” is no longer accepted. The most common form may be “forestry by First Nations,” representing a role for First Nations within existing forestry regimes. Other options include “forestry for First Nations,” in which forest managers seek to incorporate aboriginal values and knowledge in management activities and “forestry with First Nations,” in which aboriginal peoples are equal partners in forest management. However, aboriginal forestry is better understood as a potential new form of forestry that uses knowledge and techniques drawn from both traditions and conventional forestry and is based on aboriginal rights, values, and institutions. Au Canada, le terme « foresterie autochtone »gagne en popularité pour décrire le rôle grandissant des Premières nations en foresterie au cours des trente dernières années. Cet article passe en revue de nombreuses expériences et identifie des enjeux aux conséquences importantes pour les gouvernements, les gestionnaires forestiers et les Premières nations. Un régime forestier qui reflète les intérêts des gouvernements et des industriels plutôt que ceux des Premières nations, la reconnaissance inégale des droits autochtones dans les pratiques forestières, les bénéfices et les problèmes associés aux partenariats d’affaires, les limites propres à la consultation, la place des savoirs traditionnels et de la cogestion en foresterie et enfin, la variété des paradigmes forestiers composent ces enjeux. Parmi ces expériences et enjeux, nous reconnaissons l’expression de différentes façons de concevoir la participation autochtone à la foresterie canadienne. À un bout du spectre, « une foresterie qui exclut les Premières nations »n’est plus une option acceptable. La vision la plus répandue est probablement celle d’« une foresterie par les Premières nations »signifiant que celles-ci ont un rôle à jouer dans les régimes forestiers existants. Une autre conception est celle de « la foresterie pour les Premières nations »lorsque les gestionnaires forestiers tentent d’intégrer des valeurs et des savoirs autochtones à leurs activités d’aménagement. Enfin, les situations où les autochtones sont partenaires à part entière dans l’aménagement de la forêt s’inscrivent sous la rubrique « la foresterie avec les Premières nations ». Cependant, la foresterie autochtone est mieux comprise lorsqu’elle implique la possibilité d’une nouvelle foresterie qui a recours à des savoirs et des techniques inspirés à la fois des traditions et de la foresterie conventionnelle et qui est fondée sur des droits, des valeurs et des institutions autochtones.

Concerns about the management of agro-ecosystems in Ontario Canada have been precipitated by the increasing intensity of agriculture operations and concerns about its impact on the environment and human health. The management of agro-ecosystems for sustainability is particularly challenging due to their inherent features and the complex web of institutional arrangements in which they arc set. This paper focuses on the concepts of regulation and stewardship. The contribution of the environmental farm plan (EFP) program to environmental management in Ontario farms is specifically examined. The EFP program was initiated by farmers to minimize environmental impacts from farming practices; it is voluntary and founded upon the principles of stewardship. Results of a survey conducted with participants in the EFP program demonstrate that appreciable measures are being taken to manage environmental impacts from farming. The contributions of stewardship to managing agro-ecosystems are explored in the conclusion. [ABSTRACT FROM AUTHOR]

In a recent paper, we described a multi-block approach to the regulation and management of reforestation (P.J. Martin, S. Browne Clayton, and E. McWilliams (2002), "A results-based system for regulating reforestation obligations," Forestry Chronicle 78(4): 492-498). Under the multi-block approach, indicators are devised that portray the degree to which the condition of regeneration on harvested areas is consistent with forest management goals. A population of harvested areas is sampled. The current levels of the indicators are estimated and compared to threshold values. If observed levels exceed threshold levels, the population is considered adequately reforested and all reforestation obligations are met. In this paper, we describe some recent enhancements of this concept and demonstrate how the multi-block approach provides characteristics desirable in a regulatory regime. By shifting the focus of reforestation regulation from the stand level to the level of a population of harvested areas, the multi-block approach provides effective regulation, permits efficient management, and addresses several shortcomings in British Columbia's current reforestation regulations.

Abstract To satisfy public demands for environmental values, forest companies are facing the prospect of a reduction in wood supply and increases in costs. Some Canadian provincial governments have proposed intensifying silviculture in special zones dedicated to timber production as the means for pushing out the forest possibility frontiers. In this paper, we compare the traditional two-zone land allocation framework which includes ecological reserves and integrated forest management zones with the triad — a three-zone scheme which adds a zone dedicated to intensive timber production. We compare the solutions of the mixed-integer linear programs formulated under both land-allocation frameworks. We explore through sensitivity analysis the conditions under which the triad regime can offset the impact on timber production from increased environmental demands. We show that under the realistic conditions characteristic to Coastal British Columbia, higher environmental demands may be satisfied under the triad regime without increasing the financial burdens on the industry or reducing its wood supply. This occurs, however, only if regulatory constraints in timber production zone are flexible. [ABSTRACT FROM AUTHOR]
