riven by the DRIVER project, ecological restoration and non-degradation operations of coastal marine habitats have been developing in an experimental and innovative way for about fifteen years. These efforts revolve around a relatively new scientific discipline focused on restoring natural habitats, connectivity, and complex ecosystem functions. To date, a planning tool (STERE) has been developed, offering a comprehensive methodology for territories. It is supported by a strategic document (Western Mediterranean PAMM), which includes an atlas identifying areas considered suitable for the development of STERE. Together, they highlight key management challenges in terms of public action effectiveness and the maturity level achieved. Scientific expertise and monitoring have made it possible to measure both the impacts and the current limitations of these biodiversity recovery efforts at sea. Building on this solid foundation, ecological restoration must continue to enhance its knowledge base and effectiveness. At the same time, biomimicry — an interdisciplinary approach that observes and draws inspiration from living systems to foster sustainable innovation — is gaining structure. Based on principles derived from nature, it aims to design solutions that are compatible with life and conducive to ecosystem development. It also seeks to reduce the impact of proposed solutions on ecosystems and contribute to their regeneration. Biomimicry has recently seen significant growth, even becoming something of a trend, due to its broad application potential, especially in the marine environment. The convergence of these two complex and rapidly evolving disciplines is therefore promising. However, their growing popularity — combined with the complexity of working for and with living systems — requires the establishment of a shared framework to ensure that biomimicry becomes a valuable tool for ecological restoration.
