Abstract:

The objective of this study was to retrospectively evaluate, with the help of stem analysis, the growth increases of natural and planted black spruce (Picea mariana (Mill.) BSP) seedlings in 39 drainage networks located in Quebec public boreal forest and drained operationally after cutting. The ecological conditions of the sites have been described using the forest ecosystem classification for the Clay Belt of eastern Ontario. A significant effect of the drainage on 9-year periodic growth in diameter and height of natural black spruce seedlings, varying with distance from the ditch and ecological conditions, was observed. Stocking of natural black spruce seedlings was sufficient to insure the reconstruction of a forest stand both on the treated sites and on the control sites. The 5-year height growth increment of planted black spruce seedlings was weaker than that of the natural seedlings, which were located on the same sites, and it varied with distance from the ditches.

Cette étude avait pour objectif d'évaluer de façon rétrospective, à l'aide de l'analyse de tiges, les gains de croissance de semis naturels et de plants d'épinette noire (Picea mariana (Mill.) BSP) dans 39 réseaux de drainage situés en forêt boréale publique québécoise et réalisés de façon opérationnelle après coupe. Les conditions écologiques ont été décrites à l'aide de la classification écologique de la ceinture d'argile de l'Est de l'Ontario. Un effet significatif du drainage sur l'accroissement périodique de 9 ans en diamètre et en hauteur des semis naturels d'épinette noire, variant en fonction de la distance par rapport au fossé et en fonction des conditions écologiques, a été observé. Le coef ficient de distribution des semis naturels d'épinette noire s'est avéré suffisant pour assurer la reconstitution d'un peuplement forestier autant sur les sites traités que sur les sites témoins. Les plants d'épinette noire ont démontré un accroissement quinquennal en hauteur plus faible que celui des semis naturels se trouvant aux mêmes endroits et variant selon la distance par rapport au fossé.
