Database for marine and coastal restoration projects in Australia and New Zealand

The United Nations has declared 2021–2030 as the Decade on Ecosystem Restoration and the Decade of Ocean Science for Sustainable Development. These declarations emphasise the importance of restoring degraded marine and coastal ecosystems and supporting research and knowledge. The number and scale of marine and coastal restoration projects have been increasing in Australia and New Zealand over the past 40 years. However, the lack of a central repository of projects and their results limits opportunities to share knowledge to improve effectiveness. To address this gap, we developed the Australian and New Zealand Marine and Coastal Restoration Database. Information for this database was gathered from publicly available documents (peer-reviewed journal articles and technical reports) and discussions with key organisations that lead projects in Australia and New Zealand. For each project, we recorded the start date, duration, spatial scale, location, details on monitoring, and success criteria. The database includes information up until 1 June 2020. It is available online via the Australian Coastal Restoration Network website.
