Promoting site-adapted tree species is a key principle of integrative forest management, supporting resilient, productive, and biodiverse forests. Native tree species are generally prioritized because they provide a wide range of ecological benefits and are well adapted to local ecosystems. Where appropriate, carefully selected non-native species can help to achieve specific management objectives.
Prioritizing native tree species supports forest biodiversity, ecosystem functioning, and genetic diversity. Selecting species and reproductive material adapted to local site and climatic conditions helps maintain resilient and characteristic forest ecosystems.
Non-native tree species can complement native forests and support specific management objectives, such as climate change adaptation and timber production.
