Abstract
Remnant tree stands left intact following a disturbance constitute the sole seed banks available for regeneration of
coniferous species that neither bear serotinous cones nor reproduce vegetatively. The success of regeneration of tree species on
these disturbed sites is, therefore, dependent on the distance from potential seed sources. The regeneration of balsam ®r (Abies
balsamea (L.) Mill.), white spruce (Picea glauca (Moench) Voss) and white cedar (Thuja occidentalis L.) was studied at two
sites in QueÂbec's southwestern boreal forest in order to quantify the in¯uence of remnant stands on spatial distribution of
