Speaking the same language: Aligning project designations to clarify communication in restoration ecology

As we enter the United Nations Decade of Ecosystem Restoration, the need to engage in restoration activities has never been greater. Included within this need is a requirement for clear communication between researchers, practitioners, policymakers, stakeholders, and community members. To facilitate the discussion and assessment of restorative activities, we propose two decision trees to differentiate between key restoration terms (Reclamation, Rehabilitation, Ecological Restoration, Rewilding, Landscape Restoration, Intra-Ecosystem Restoration, Reference Condition Restoration, and Ecological Reclamation) and to clarify how they relate to each other, based upon project scope and desired/intended project outcomes. Continued use of unclear terminology impedes practitioners or researchers from using the literature efficiently, to find precedents that could assist their current efforts. As such, increasing clarity of communications will ensure restoration is discussed within a framework of well-defined and agreed upon terms. It is our hope that this suggested framework will contribute to the ongoing and much needed terminology debate and help enhance cohesion on the use of key terms within the restoration focused literature. Given the increased focus upon restoration projects of any kind, especially during the UN's decade of ecosystem restoration, it is more important than ever that restoration practitioners speak the same language.
