For the sake of resilience and multifunctionality, let’s diversify planted forests!

Journal article

As of 2020, the world has an estimated 290 million hectares of planted forests and this number is continuously increasing. Plantations composed mainly of one tree species under intensive management contribute 131 million hectares to these planted forests. Although monospecific plantations are important in providing timber, they harbour less biodiversity and are potentially more susceptible to disturbances than natural or diverse planted forests. Here, we point out the increasing scientific evidence for increased resilience and ecosystem service provision of functionally- and species-diverse planted forests (hereafter referred to as diverse planted forests) compared to monospecific plantations. Furthermore, we propose five concrete steps to foster the adoption of diverse planted forests: (1) improve awareness of benefits and practical options of diverse planted forests among land-owners, managers, and investors; (2) incentivize tree species diversity in public funding of afforestation and programs to diversify current maladapted plantations; (3) develop new wood-based products that can be derived from many different tree species; (4) invest in research to assess landscape benefits of diverse planted forests for functional connectivity and resilience to global-change threats; and (5) improve the evidence base on diverse planted forests, in particular in currently underrepresented regions, where new options could be tested.
