“…Repeated short rotations would, under this scenario, result in declining soil C stocks. However, other authors concluded that there is little evidence that harvesting with immediate reforestation significantly affects soil carbon content (e.g., Heath et al 2002, Lee et al 2002, Martin et al 2005, Ter-Mikaelian et al 2008. Finally, Liski et al (2002) suggested that an increase in soil C with shortened rotations could be expected because shorter periods between tree harvesting operations tend to increase foliage and branch litterfall from standing trees.…”

The objective of the study was to assess the responsiveness of the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3) to management scenarios that included three rotation lengths (50, 100 and 250 years) under harvest and fire disturbances in six forest types (poplar deep soil, black spruce deep soil, jack pine deep and shallow soils, hardwood mixedwood and other conifer lowland). Outputs from five carbon (C) pools were considered: merchantable stemwood (stump height of 30 cm, minimum DBH of 9 cm and a minimum top diameter of 7 cm), deadwood, soil C, total ecosystem C and cumulative total ecosystem C emissions. Yield curves strongly affected the predicted size of all five pools. Longer rotation lengths led to larger pools with the relative differences between rotation lengths varying with stand types. Pools associated with poplar were usually the largest while those of jack pine on shallow sites were generally the smallest. When compared to the starting point of the simulations, cumulative total ecosystem C and C emissions increased with the 100-and 250-year harvest rotations (HARV100 and HARV250, respectively) and declined with the 50-year harvest rotation (HARV50). Fire disturbances resulted in stable pools of cumulative ecosystem C and declines in C emissions. CBM-CFS3 provided realistic pool values but the authors suggest further development of the model depiction of ecosystem processes, especially with respect to the treatment of respiration. In general, the authors recommend that forest management planners consider using an integrated approach that links multiple proven and accepted models under appropriate model linking software.

“…10 The first is to conserve existing carbon stocks (or delay their release), through practices such as delayed harvest, avoided harvest (conservation), fire or insect control, or improved soil management (Price et al 1997, Kurz et al 1998, Kurz and Apps 1999, Bhatti et al 2001, Amiro et al 2002. The second strategy is to increase the rate at which the forest sequesters and stores new carbon, through intensive management practices such as tree planting, species manipulation, stand thinning, or fertilization (Hoen and Solberg 1994, Sedjo and Botkin 1997, Sohngen and Mendelsohn 1998, Sampson and Scholes 2000, Lee et al 2002. The actual effectiveness of these different practices for increasing forest carbon will vary with a number of factors, including the initial age class structure of the forest, species mix, and the pattern of past disturbances in a particular forest area (Kurz and Apps 1999, Sampson and Scholes 2000, Kurz et al 2002.…”

Canada's forests -particularly the boreal-are a major storehouse of carbon. How they are managed could significantly affect Canada's greenhouse gas emissions while also presenting a new revenue source for forest managers. This study attempts to assess how a carbon price could affect forest management, particularly in Canada's boreal plains region. An integrated modelling approach is developed to incorporate both forest carbon and timber supply considerations within an optimal management framework. This modelling approach allows for consideration of alternative market and regulatory scenarios, along with a range of possible management intensity and harvest scheduling options over the landscape. The overall conclusion is that carbon incentives will increase the value of the boreal forest-potentially quite significantly-and will generally encourage management changes consistent with sustainable forest management practices.Key words: boreal forest, carbon credits, timber supply, market incentives, sustainable forest management, optimization, Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3), Woodstock Forest Management Model RÉSUMÉLes forêts du Canada, particulièrement la forêt boréale, constituent d'importants réservoirs de carbone. Leur aménage-ment pourrait avoir un impact significatif sur les émissions de gaz à effet de serre tout en constituant une nouvelle source de revenus pour les personnes en charge de leur gestion. Cette étude tente d' évaluer comment la valeur du carbone pourrait affecter l'aménagement forestier, particulièrement dans la région des plaines boréales du Canada. Une approche selon une modélisation intégrée est élaborée pour incorporer à la fois le carbone forestier et les possibilités d'approvisionnement en matière ligneuse selon un cadre d'aménagement optimal. Cette modélisation permet l' étude de marchés alternatifs et des scénarios légaux, ainsi que plusieurs intensités possibles d'aménagement et d' options de calendriers de récolte pour un écosystème donné. La conclusion générale est que les mesures incitatives reliées au carbone permettront l'accroissement de la valeur de la forêt boréale, et ce d'un niveau potentiellement significatif, et encourageront généralement des modifications de la gestion qui seront conformes avec les pratiques d'aménagement forestier durable.Mots clés : forêt boréale, crédits de carbone, approvisionnement en matière ligneuse, mesures incitatives du marché, amé-nagement forestier durable, optimisation, modèle du bilan du carbone du secteur forestier canadien (CBM-CFS2), modèle d'aménagement forestier Woodstock

“…Boreal ecosystems have large C pools present which account for approximately 15 % of the world's terrestrial C (Harding et al, 2001;Banfield et al, 2002;Lee et al, 2002). The large amounts of C stored in Boreal ecosystems have a high potential to release C as climate changes due to alterations of temperature and growing season length (Billings et al, 1998;Payment and Jarvis, 2000;Harding et al, 2001;.…”

In Boreal ecosystems carbon is also released through both natural and anthropogenic disturbance and changes in the disturbance through land management need to be quantified across all land types (Halldin et al, 1999;Bhatti et al, 2002;Lee et al, 2002). There is also a need for greater understanding of C dynamics within these systems to fully understand the cycling of C and how changes to climate could affect C pools and fluxes.…”
