Populations of invasive wild mammals have contributed significantly to the total unwanted impacts of biological invasions. They are known to impact forest ecosystems globally, but reviews summarizing this information are currently lacking. Here we (1) review the ecological characteristics of mammal invasions in forests; (2) characterize the range of ecological impacts on forest communities and the economic consequences of those impacts; (3) review what is known about interactions between the impacts of invasive mammals and other drivers of global change; and (4) consider the complex ecological and socio-economic challenges of simultaneously managing multiple invasive mammals and native biota affected by them. The unwanted impacts of invasive herbivores and predators are intensifying in many parts of the world and the need to manage their impacts to prevent further loss of indigenous biodiversity and damage to productive assets is greater than ever. However, management needs to be conducted within appropriate social, cultural, ethical, and animal welfare frameworks. Achieving effective management of populations of mammals invasive in forest ecosystems will require the filling of many knowledge gaps, including: better understanding their impacts; strategic options and tactical solutions for managing them; and achieving social licence to operate.
