Global impacts of exotic eucalypt plantations on wildlife

Résumé fourni par la source

The establishment of exotic tree plantations poses a pervasive threat to wildlife across the globe. Among the most important tree species used for forestry purposes worldwide are members of the genus Eucalyptus, which have now been established in at least 107 countries outside of their native range. When introduced into non-native areas, eucalypt plantations are associated with myriad novel challenges for native fauna, and have often been associated with reductions in the biodiversity of local communities. However, similar to other anthropogenic habitats, eucalypt plantations can also create novel opportunities for species that can allow them to survive and thrive in these novel environments. In this review, we use eucalypt plantations as a case study for understanding the ecological and evolutionary responses of wildlife to anthropogenic habitat loss and change. We begin by summarising the main avenues of research addressing the study of wildlife responses at the individual, community, and ecosystem levels, and highlight critical research gaps. We also consider the characteristics of different types of eucalypt plantations and how such attributes are linked with the ability of animals to respond appropriately to the establishment of plantations, and summarise important considerations for the conservation of animal communities in these human-altered habitats.
