|Abstract:||The first objective of this project was to understand the effect of natural fire disturbance on the availability and abundance of dead trees (snags) and their use by cavity-nesting birds in the northeastern part of Quebec’s unmanaged boreal forest stands. Secondly, I aimed to understand the effects of the structure and composition of the boreal forest on bird species communities along two long-term chronosequences after fire (0 to > 200 years postfire). Results show that tree mortality follow a U-shape pattern, with more snags in young and old-growth forests, where I also found more nest cavities and foraging signs. Although bird species richness did not vary greatly according to the different age classes, many species were lost and others recruited following succession stages. This study highlights the need to protect the forest at all stages, especially old-growth, which provides a heterogeneous environment suitable for several bird species.|
