Résumé

We compared how bird communities differed between burned and logged stands in black spruce (Picea mariana) forests of the boreal shield in Quebec and mixed-wood forests on the boreal plain in Alberta and Saskatchewan. Bird community composition was quite different in burns and clearcuts shortly after disturbance. In burns, cavity nesters and species that forage on beetles in dead trees predominated, whereas clearcuts were dominated by open-country species. Generally, snag-dependent species decreased and shrub-breeding species increased by 25 yr postfire. Species that forage and nest in canopy trees were more common 25 yr postlogging because of the retention of live residual trees. The bird communities tended to converge over time as the vegetation in burns and logged areas became more similar. Black-backed Woodpeckers (Picoides arcticus) and Three-toed Woodpeckers (Picoides tridactylus) exploit recently burned coniferous forest to forage on woodboring insect larvae (Cerambycidae and Buprestidae) and bark beetle larvae (Scolytidae) for a short period after fire and then decline. Black-backs were absent from mature forests and found at low density in old-growth forest. Over the long term, burns may be temporary sources for fire specialists. The major conservation issue for fire- associated species is salvage logging, because woodpecker foraging and nesting trees are removed. Maintenance of suitable amounts of postfire forests spared from salvage logging is essential for sustainable forest management. Climate change is predicted to alter fire cycles: they will be shorter in the prairies leading to a shortage of old-growth forest and will be longer in Quebec leading to a shortage of younger forest.
