Résumé

In order to explain conifer species recruitment in Canada's southeasternboreal forest, we characterized conifer regeneration micrositesand determined how these microsites vary in abundance during succession.Microsite abundance was evaluated in deciduous, mixed and coniferousstands along a 234-yr postfire chronosequence. Conifers were mostoften found in relatively well-illuminated microsites, devoid oflitter, especially broad-leaf litter, and with a reduced cover oflower vegetation (< 50 cm tall). Although associated with moss-richforest floor substrates, Abies balsamea was the most ubiquitouslydistributed species. Picea glauca and especially Thuja occidentalisseedlings were frequently found on rotten logs. Light measurementsdid not show differences among seedling species nor between standtypes. The percentage cover of broad-leaf litter decreased significantlyduring succession. Also, rotten logs covered with moss occupieda significantly larger area in the mid-successionnal stands thanin early successional deciduous or late successional coniferousstands. The results suggest that the presence of specific forestfloor substrate types is a factor explaining low conifer recruitmentunder deciduous stands, conifer codominance in the mid-successionalstage, and delayed Thuja recolonization after fire. Results alsosuggest that some facilitation mechanism is responsible for theobserved directional succession.
