Research Reveals Negative Impact of Clearcutting on Boreal Forest Birds in North America and Europe
Boreal forests, which span North America, Europe, and Asia, are extensively managed for timber production, often employing clearcutting. Clearcutting, a method that removes most or all trees from an area, significantly alters habitats for forest species. A study conducted by the University of Turku, in collaboration with the University of Helsinki, investigated the effects of clearcutting on resident forest birds in Southwest Finland. Unlike previous research that focused on migratory species, this study specifically examined birds that remain in these forests year-round, as they are more susceptible to local habitat changes. Using Passive Acoustic Monitoring (PAM), researchers collected bird vocalization data before and after clearcutting operations. The analysis, which combined Artificial Intelligence and manual effort, identified and analyzed the vocalizations of 12 resident forest bird species from thousands of hours of recordings. The findings indicate that intensive clearcutting negatively affects bi...
