Abstract
Owen, K. C., A. D. Melin, F. A. Campos, L. M. Fedigan, T. W. Gillespie, and D. J. Mennill. 2020. Bioacoustic analyses reveal that bird communities recover with forest succession in tropical dry forests. Avian Conservation and Ecology 15(1):25. https://doi.org/10.5751/ACE-01615-150125
Highlights
The impacts of environmental change on wildlife are well documented, with overwhelming evidence demonstrating that habitat loss and fragmentation have negative impacts on biodiversity (Brooks et al 2002, Fahrig 2003)
We found that species richness and abundance were similar across this 23-year interval, bird community composition changed because several forest-specialist species were only detected in the later period
Our research reveals that the regenerating tropical dry forests of northwestern Costa Rica have recovered species richness and abundance levels and are currently undergoing a succession in community composition toward that of a primary tropical dry forest
Summary
The impacts of environmental change on wildlife are well documented, with overwhelming evidence demonstrating that habitat loss and fragmentation have negative impacts on biodiversity (Brooks et al 2002, Fahrig 2003). Previous investigations of habitat restoration and forest regeneration have shown that monitoring can help to guide good conservation practice (Wortley et al 2013). In the northwestern United States, monitoring efforts showed that an endangered butterfly species successfully established itself in a recovering forest, but indicated that larval resources were insufficient for long-term recovery (Schultz 2001). These examples highlight the importance of monitoring restoration programs to inform future conservation efforts
