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 (r
2 >= 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]- Published

Increased emphasis on forest complexity, resilience, and biodiversity has renewed interest in northern hardwood forests. In parallel, there is concern of impacts of traditional, timber-oriented regeneration methods on successional trajectories and tree communities. To ensure compatibility of emerging goals with site biological capacity, assessment of common silvicultural methods across forest conditions is imperative. This work utilizes a long-term dataset of 407 sampling plots from the Bartlett Experimental Forest in New Hampshire, USA, over 70 years. Topographic and meteorological variables were utilized to test the effects of site conditions and silviculture on tree species diversity and composition. Results show a decline in diversity over time that reflects a shift toward dominance of late successional species, which vary with site-specific conditions. The effect of silviculture was not detectable, and differences in tree communities were attributed to pre-existing conditions of site variables prior to installation of experimental treatments. Tree diversity and composition for both 1932 and 2003 measurements were correlated with solar insolation, local wind speed, and hydrological catchment area. The collective findings highlight the long-term stability of species under past silvicultural regimes, that some areas are more facilitative/limiting to goals of enhancing tree biodiversity and emerging technologies can capture species–site interactions in northern hardwoods.

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.

Forestry is becoming more complex as a result of diverging societal demands. Indigenous Peoples' reconciliation and the challenges of climate change call for research that embraces transdisciplinarity, reciprocity, and problem-focused learning at the landscape scale. Both globally and in Canada, forestry and forest research are struggling to keep pace with this growing complexity. Place-based collaborative research and learning initiatives, described here as "learning landscapes," offer an under-explored approach to meeting diversifying goals for forest landscapes. We describe recent progress in Quesnel, British Columbia, where researchers and local institutions are engaging to strengthen resilience and innovation in the forest sector. We first define the concept of learning landscape in the context of transdisciplinary sustainability science, and then illustrate this approach using the case study of Quesnel. We describe a process of systems diagnosis, including asset mapping and analysis of potential forestry pathways through a "best bets" framework. We propose a Theory of Change as a way forward, outlining opportunities for government, industry, and communities in developing regional capacity for integrated management and high-value forest products. We reflect on the contributions of learning landscapes to knowledge generation, experiential learning, and institutional development, and discuss implications for steering decision-making in locally driven sustainability transitions.

33. First Nations, forest lands, and “aboriginal forestry” in Canada: from exclusion to comanagement and beyond.

TREES ,FOREST management ,FORESTS & forestry ,AGRICULTURE ,SILVICULTURAL systems ,VEGETATION management - Abstract
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.

The Douglas-fir forests of coastal British Columbia are within the most heavily modified forest ecosystem types in coastal BC and local land managers are developing new forestry practices to retain elements of old growth within the managed forest area. To determine how successful these practices are requires the selection and monitoring of appropriate attributes and knowledge on how they change with stand development. In this paper we summarize previously published results from an extensive data set on four Douglas-fir dominated sites located on eastern Vancouver Island. Data were collected as part of the Coastal Forest Chronosequences project which was addressing questions on (1) how does conversion to managed forests impact species and forest structural diversity and (2) how does this diversity recover in older second-growth stands. Each site contained four stands, a postharvest chronosequence: regeneration (R, 5–10 years), immature (I, 25–45 years), and maturing (M, 75–95 years) stands, and an old growth (O, >240 years) control stand. Over 20 attributes are summarized including structural attributes, and at three sites, detailed biodiversity and process attributes. All old-growth plots exceeded the minimum age criteria and some but not all of the minimum structural attribute criteria for old-growth Douglas-fir forests in the US Pacific Northwest, reflecting regional or site type differences. Most structural attributes showed their greatest change within the first 100 years, although older stands (M and O) still differed based on tree and snag sizes and tree mass or basal area. Most species abundance and richness attributes and process attributes clearly differentiated R from the forested stages but were of less value for differentiating among older (M and O) stands. Arboreal lichen abundance and species richness; the abundance of cryptogams, achlorophyllus plants, litter collembola, and specific species of fungi and carabids; litter fall and gap fraction were the exception, these attributes clearly differentiating M from O stands. In postharvest stands, the overall pattern of change with succession for most attributes, as inferred from the chronosequence, was confirmed to be very different from a previously published conceptual model for post-fire succession. Compared to the post-fire model, the greatest changes in the postharvest stands occurred early in stand development, associated with canopy closure. Although stand structural attributes can clearly be used to distinguish old-growth features in managed forest stands, none-the-less it is important to monitor and demonstrate, at least for a selection of nonstructural attributes, that forestry practices are effective in maintaining biodiversity and associated processes of old-growth forests in the managed forest area. Key words: old-growth forest, succession, Douglas-fir forest, criteria and indicators, biodiversity, managed forest.Les forêts de douglas comptent parmi les types d'écosystèmes forestiers les plus fortement modifiés dans les zones côtières de la Colombie-Britannique, et les aménagistes forestiers locaux mettent au point de nouvelles pratiques forestières pour conserver des éléments de forêt ancienne dans la forêt aménagée. Pour déterminer l'efficacité de ces pratiques, il faut bien choisir et surveiller des attributs de forêt ancienne, et savoir comment ils évoluent au cours du développement d'un peuplement. Dans cet article, nous résumons des résultats déjà publiés provenant d'une vaste base de données, sur quatre sites dominés par le douglas, dans l'est de l'île de Vancouver. Les données ont été recueillies dans le cadre du projet sur les chronoséquences des forêts côtières, lequel abordait notamment les questions suivantes : (1) Quel est l'effet de l'aménagement des forêts sur la diversité des espèces et sur la structure des forêts? (2) Comment cette diversité se rétablit-elle dans les peuplements plus âgés de seconde venue? Chaque site comprenait quatre peuplements constituant une chronoséquence post-récolte : un peuplement en régénération (R, de 5 à 10 ans), un peuplement immature (I, de 25 à 45 ans), un peuplement en cours de maturation (M, de 75 à 95 ans) et un peuplement ancien servant de témoin (O pour « old growth », plus de 240 ans). Nous résumons plus de 20 attributs, notamment des attributs structuraux et, pour trois sites, des attributs détaillés liés à la biodiversité et aux processus. Toutes les placettes d'étude dans les peuplements anciens satisfaisaient au critère d'âge et à certains des critères d'attributs structuraux établis pour les forêts anciennes de douglas, dans les États du nord-ouest des États-Unis donnant sur le Pacifique, ce qui reflète des différences régionales ou liées au type de site. Pour la plupart des attributs structuraux, le changement maximal se produit au cours des 100 premières années, quoique les stades M et O se distinguent toujours sur les plans de la taille des arbres et des chicots, ainsi que de la masse ou de la surface terrière des arbres. La plupart des attributs d'abondance et de richesse en espèces et des attributs de processus différenciaient clairement les peuplements R des autres, mais sont apparus moins utiles pour différencier les peuplements plus âgés (M et O). L'abondance et la richesse en espèces des lichens corticoles, l'abondance des cryptogames, des plantes sans chlorophylle, des collemboles de la litière et d'espèces particulières de champignons et de carabidés, ainsi que la chute de litière et la fraction de trouées faisaient exception : ces attributs différenciaient clairement les peuplements M et O. Dans les peuplements établis après une récolte, le patron général des changements successionnels pour la plupart des attributs, d'après la chronoséquence, s'est avéré très différent d'un modèle conceptuel de la succession après incendie, lequel a fait l'objet d'une publication. Par comparaison à ce modèle, les changements les plus importants dans les peuplements, après récolte, se produisent au début du développement des peuplements, en association avec la fermeture du couvert. Bien qu'il soit évident que des attributs structuraux des peuplements peuvent servir à distinguer des caractéristiques de forêt ancienne dans les peuplements aménagés, il est important de faire un suivi et de montrer, au moins pour certains attributs non structuraux, que les pratiques forestières permettent de maintenir la biodiversité et les processus connexes des forêts anciennes sur le territoire forestier aménagé. Mots clés : forêt ancienne, succession, forêts de douglas, critères et indicateurs, biodiversité, forêt aménagée. [Traduit par la rédaction] [ABSTRACT FROM AUTHOR]

The article focuses on Ecology and silviculture of temperate mixedwood forests. Topics discussed include the ecology and silviculture of these systems has been a consistent area of study given the potential benefits of mixed-species forests in relation to minimizing forest health and climate change impacts; and the occasional higher levels of productivity observed for species mixtures relative to single-species stands.

FOREST management ,FORESTS & forestry ,NATURAL resources management ,VEGETATION management ,LANDSCAPE protection - Abstract
Developing and implementing landscape management planning is an important step towards shifting the traditional focus of forest management from managing resource flows, such as timber and wildlife habitat, to managing forests. This paper describes and applies a forest landscape management design process with a GIS-based landscape management model (LANDMAN) that incorporates harvesting intervention patterns and performance indicators using spatial structure measurements. In a case study, one small landscape was identified and quantified using the spatial structure measurements. The structural effects of four different harvesting patterns (scatter, negative edge distribution, edge progressive, and nuclei progressive) on landscape fragmentation were explored. Performance indicators quantified structural changes over time. Degree of structural change varied greatly among the four harvesting patterns. The scatter harvesting pattern created fragmented landscapes, while the nuclei progressive pattern significantly reduced fragmentation. Likewise, the negative edge distribution and edge progress harvesting patterns also tended to reduce fragmentation and mimic patterns of natural disturbances such as fire and insects. In any event, the case study demonstrated that geographically based harvesting patterns and performance indicators could provide an opportunity to design management for the creation of alternative forest landscapes. The paper concludes that forest landscape management, with its spatial structure focus, is a desirable evolution. [ABSTRACT FROM AUTHOR]

DECISION support systems ,COMMUNITY forestry ,FOREST management ,FORESTS & forestry - Abstract
Many of the intrinsic facets of forest planning are surrounded by uncertainty. Decision-makers strive to improve their understanding of the sources of uncertainty and their impact on the decision-making process. However, uncertainty is rarely integrated into real-world forestry applications or into decision support tools used in forest planning problems. To identify the needs, interests, and challenges of managing uncertainty in forest planning, we interviewed forestry professionals. All the interviewees indicated the positive potential of a tool that could address some facets of uncertainty. Additionally, we conducted a review of the most recent literature on this topic to understand current hot topics and future trends that could help address real-world challenges. This study highlights the next steps to incorporate uncertainty into the decision support systems for forest planning. However, to strengthen the bond between the practical needs of forestry professionals and the theoretical approaches proposed by recent literature, more effort should be placed on defining terminology and formulating a theoretical framework for uncertainty analysis. This will provide the forestry community with a common language and typology, help increase its general understanding, and improve communication between forestry researchers, forestry professionals, and other stakeholders.
