“…According to yield curves for black spruce stands of the study area (Garet et al 2009), total tree mortality rates (all species) were proportional to the temporal pattern of change of living tree volume as previously observed by Aakala et al (2008). At the species level, even though balsam fir is thought to be more susceptible to mortality agents than black spruce (Burns andHonkala 1990, Aakala et al 2007), the increasing snag availability with TSF seems unrelated to the increasing occurrence of balsam fir in old-growth stands (Fig.…”

We studied the availability and characteristics of snags and their use by cavity-nesting birds in the northeastern part of the Canadian boreal forest. We built up two long-term (> 200 years) chronosequences following time since the last fire in the unmanaged boreal forest of northeastern Québec, one in the balsam fir-white birch domain (southern region) and one in the spruce-mosses domain (northern region). We then sampled and characterized snags and live trees in 30 stands from each of these two chronosequences. We also looked for nest cavities on all sampled snags, performed bird inventories by point counts, and calculated tree mortality rate from permanent sample plots. Results show that mortality rates follow a U-shaped pattern, with more snags of large diameter (> 20 cm DBH) in young (< 50 years) and in old (> 200 years) forests. In the latter, we also found more nest cavities than in any other age classes. Although abundance of primary cavity nesters (excavating species) did not vary among age classes, secondary cavity nesters (using cavities already available) tend to be more numerous in older forests. Our results highlight the capacity for young and old-growth forests to provide quality habitat for species that are dependent on large snags. Proper forest management should maintain a mosaic of different age forest stands, including snags, to promote biodiversity and provide important resources for resident bird species.Keywords snags, cavity nesting birds, boreal forests, old-growth, long term chronosequence, time since fire, mortality rate, basal area Addresses Lowe and Pothier, Centre d'étude de la forêt, Département des sciences du bois et de la forêt, Pavillon Abitibi-Price,

“…Consequently, similar to the development of succession rules of Vasiliauskas et al (2004), the literature was used as background information to make required input adjustments from expert opinion to develop input tools that are useable within the specific requirements of the wood supply models used here. For example, although published yield curves for black spruce from adjacent Québec are available (Garet et al 2009), the algorithms are based on species and site index that cannot be directly used in Ontario' s wood supply modeling. In Ontario, yield algorithms are based on forest unit and site class as derived through Plonski (1981).…”

“…and lowland black spruce stands can result from either fire origin or through canopy succession (based upon Chen et al 2009, Paré and Bergeron 1995for mixedwoods and Harper et al 2003Garet et al 2009 for black spruce). Mixedwood stands where trembling aspen was dominant or where trembling aspen and spruce were in equal proportions were considered fire origin stands; where white birch exceeded trembling aspen or where cedar was present were considered succession origin (based upon Bergeron 2000).…”

“…In combination with LiDAR technology (Woods et al 2011), these inventory tools should help meet the challenges of better identifying stands in mid-and late-seral stages of succession. In forest management scenarios where the maintenance of mid-and late-seral succession stages is important, the development of yield curves needs to consider replacing age with time-since-fire as suggested by Garet et al (2009). Yield curves must then be linked to succession pathways.…”

Challenges and implications of incorporating multi-cohort management in northeastern Ontario, Canada: A case study

In northeastern Ontario, the natural fire cycle is long, resulting in large areas of forest in an uneven-aged condition. Under Ontario forest legislation requiring emulation of natural disturbance regimes, extended rotations and multi-cohort management present options that may meet landscape targets. We used a forest management wood supply model to compare scenarios of current even-aged management, extended rotations, and multi-cohort management (adds partial harvesting). Because science-based information to incorporate late successional forest stages into wood supply modeling is lacking in boreal Ontario, we adjusted the current even-aged inputs to account for mid-and late-seral conditions. Based primarily on expert opinion, adjustments were made to the Forest Resources Inventory age, yield curves, and succession rules; and partial harvesting was added. For modeling, we specified three broad succession groupings (even-aged, two-to three-aged, and all-aged) and established targets of 50%, 25% and 25% of the landscape area, respectively. The current even-aged scenario met even-aged targets but not multi-aged targets. Extended rotations and multi-cohort management scenarios met all the succession grouping targets over the long term. Wood supply was highest for the even-aged scenario, slightly lower for multi-cohort management scenario, and much lower for the extended rotations scenario. Road usage and relative cost was highest for the extendedrotations scenario and lowest for the even-aged scenario. Multi-cohort management may represent a compromise between maximizing harvest levels using even-aged management and retaining mid-and late-succession habitat structures.Keywords: emulation of natural disturbance, sustainable forest management, multi-cohort, variable rotations, extended rotations, wood supply résumé Dans le nord-est de l'Ontario, les longs cycles naturels de feux font que de vastes zones de forêt deviennent inéquiennes. Comme la législation forestière de l'Ontario oblige à imiter les régimes de perturbations naturelles, il est envisageable d'atteindre ces objectifs au niveau du paysage par l'allongement des rotations et l'utilisation de l'aménagement multi-cohortes. Nous avons utilisé un modèle d'approvisionnement en forêt aménagée pour comparer scénario d'aménagement équienne avec ceux comportant un allongement des rotations et un aménagement multi-cohortes (incluant la coupe partielle). Puisque les informations scientifiques pour intégrer les stades de succession écologique tardifs dans la modélisation de l'approvisionnement faisaient défaut pour la région boréale de l'Ontario, nous avons ajusté les paramètres du modèle équienne pour tenir compte des conditions de succession moyenne et tardive. En nous inspirant surtout de l' opinion des experts, nous avons ajusté l'âge, les courbes de rendement et les règles de successions provenant de l'inventaire forestier provincial; nous avons ajouté la coupe partielle. Pour effectuer la modélisation, nous avons spécifié trois grands groupes de succession...
