1. Salvage logging following natural disturbances may alter the natural successional
trajectories of biological communities by affecting the occurrences of species,
functional groups and evolutionary lineages. However, few studies have examined
whether dissimilarities between bird communities of salvaged and unsalvaged forests are more pronounced for rare species, functional groups and evolutionary
lineages than for their more common counterparts.
2. We compiled data on breeding bird assemblages from nine study areas in North
America, Europe and Asia, covering a 17-year period following wildfire or windstorm
disturbances and subsequent salvage logging. We tested whether dissimilarities based
on non-shared species, functional groups and evolutionary lineages (a) decreased or
increased over time and (b) the responses of rare, common and dominant species varied, by using a unified statistical framework based on Hill numbers and null models.
3. We found that dissimilarities between bird communities caused by salvage logging
persisted over time for rare, common and dominant species, evolutionary lineages
and for rare functional groups. Dissimilarities of common and dominant functional
groups increased 14 years post disturbance.
4. Salvage logging led to significantly larger dissimilarities than expected by chance.
Functional dissimilarities between salvaged and unsalvaged sites were lower
compared to taxonomic and phylogenetic dissimilarities. In general, dissimilarities
were highest for rare, followed by common and dominant species.
5. Synthesis and applications. Our research demonstrates that salvage logging did not
decrease dissimilarities of bird communities over time and taxonomic, functional
and phylogenetic dissimilarities persisted for over a decade. We recommend resource managers and decision makers to reserve portions of disturbed forest to
enable unmanaged post-disturbance succession of bird communities, particularly
to conserve rare species found in unsalvaged disturbed forests.
