Inspired by the DRIVER project, ecological restoration and non-degradation operations of coastal marine habitats have been developing in an experimental, innovative, and operational manner over the past few years. These efforts revolve around a relatively recent scientific discipline focused on restoring natural habitats, ecological connectivity, and complex ecosystem functions. Scientific expertise and monitoring have made it possible to measure the impacts — but also the current limitations — of these efforts to reclaim marine biodiversity. Thus, based on this solid foundation and following this initial ten-year phase, ecological restoration must continue to improve its knowledge and effectiveness. At the same time, biomimicry — which aims to observe and understand the living world to foster sustainable innovation — is being shaped through an interdisciplinary approach. Drawing its principles from nature, biomimicry allows us to envision forms adapted to the living world and conducive to its development. It also aims to reduce the impact of proposed solutions on ecosystems and contribute to their regeneration. Biomimicry has recently gained momentum, even becoming something of a trend, due to its vast potential for application, especially in the marine environment. The convergence of these two complex and evolving disciplines is therefore promising. However, their growing success, coupled with the complexity of working for and with living systems, calls for the establishment of a shared framework to ensure that biomimicry becomes a valuable tool for ecological restoration.
