SEE PEER REVIEW
Rapid global change and increasing human use of resources have led to the widespread loss and degradation of many ecosystems, and these trends are projected to maintain or even increase. Counteracting these trends requires flexible conservation approaches to maintain and restore ecosystem functioning and to enhance ecosystem resilience. We argue that rewilding, as a dynamic and low-intervention approach to conservation, can complement and support conservation efforts to protect species and habitats of conservation concern. We identify functional diversity and ecosystem complexity, natural disturbance and stochasticity, and connectivity and dispersal, as three important domains related to ecosystem processes that can be restored and maintained via rewilding. We use concepts from resilience and complexity theory to describe the ecological consequences of restoring and maintaining these process-related ecosystem aspects, and we discuss important socio-economic implications of rewilding. Finally, we provide practice-oriented guidelines for rewilding-based conservation.
INTRO: The authors first advocate rewilding as a tool to restore degraded ecosystems. To do that, they identify the main ecosystem processes that can be recovered via rewilding. They then propose a discussion about the ecological consequences and the socio-economic implications of rewilding. On this basis, they finally provide guidelines to put into practice a rewilding-based conservation.
MERITS: The authors made a thorough and very value review of the positive impacts of rewilding in both, ecological and socio-economic terms. Furthermore, they go one step further and propose a practical guideline for rewilding. Conservation science must be applied as much as possible, and this paper follows this line.
CRITIQUE: The only thing I missed was an example of the socio-economic implication of rewilding that are going to be discussed.
DISCUSSION: This study offers concrete solutions to restore certain ecosystem services. The importance of this study relies on its applied approach.
