Abstract

Purpose of review Forests are frequently exposed to natural than monocultures to small mammalian herbivores, soil- disturbances, which are likely to increase with global change, borne fungal diseases and specialized insect herbivores. and may jeopardize the delivery of ecosystem services. Admixing broadleaves to conifers also increases the resistance Mixed-species forests have often been shown to be more pro- to fire and windstorms when compared to pure conifer stands. ductive than monocultures, but it is unclear whether this re- However, mixed forests may be more affected by drought sults from mixed stands being in part more resistant to various depending on the species in the mixture. biotic and abiotic disturbance factors. This review investigates Summary Overall, our findings suggest that mixed forests are more resistant to natural disturbances that are relatively small- the relationships between tree diversity and stand resistance to natural disturbances and explores the ecological mechanisms scale and selective in their effect. However, benefits provided by mixtures are less evident for larger-scale disturbances. behind the observed relationships.
