“…At the time the study was established(DeLong et al, 2005), the Mount Seven study area was considered to be transitional between the Kootenay Moist Cool ICH biogeoclimatic variant (ICHmk1) and the Dry Cool Montane Spruce subzone (MSdk)(Braumandl and Curran, 1992). Following refinement of biogeoclimatic mapping boundaries, it is now well within the MSdk.…”

Mechanical site preparation is assumed to reduce soil C stocks by increasing the rate at which the displaced organic material decomposes, but the evidence is equivocal. We measured rates of C loss of forest-floor material in mesh bags either placed on the surface or buried in the mineral soil at four sites in different regional climates in British Columbia. During the 3-year incubation, buried forest-floor material lost between 5% and 15% more C mass than material on the surface, with the greatest difference occurring at the site with the lowest annual precipitation. Studies of the long-term fate of buried and surface humus are needed to understand the net effects of site preparation on soil C stocks.Key words: humus, decomposition, soil, carbon, site preparation.Résumé : On assume que la préparation mécanique de terrain réduit les réserves de C dans le sol en augmentant le taux de décomposition de la matière organique qui a été déplacée mais les indices sont équivoques. Nous avons mesuré le taux de perte de C dans les matériaux de la couverture morte à l'aide de sacs-filets placés en surface ou enfouis dans le sol minéral, à quatre endroits sous différents climats en Colombie-Britannique. Durant les trois années d'incubation, les matériaux de la couverture morte qui avaient été enfouis ont subi des pertes 5 à 15 % plus élevées que les matériaux placés en surface; la plus grande différence a été observée à l'endroit où la précipitation annuelle était la plus faible. Des études sur le destin à long terme de l'humus enfoui et en surface sont nécessaires pour comprendre les effets nets de la préparation de terrain sur les réserves de C dans le sol.

“…Harvesting may not be the most pragmatic option as Armillaria is considered a 'disease of the site' which spreads in expansive mycelial clones which range in size from 1 to 5 hectares in some areas, and 20-965 hectares in others (Hagle, 2006). Established mycelia are essentially permanent, even if stump and root removal is undertaken (DeLong et al, 2005;Vasaitis et al, 2008). General forest management operations also seem to favor the fungus (Morrison and Mallet, 1996;Cruickshank, 2000) and planted seedlings are highly susceptible to infection (Piercey-Normore and Bérubé, 2000).…”
