The Handbook includes an introduction to native oyster restoration, information about starting a restoration project, current methods of restoration in practice, biosecurity recommendations and an outline of how to effectively communicate a restoration project. This publication has been written as an Ostrea edulis specific annex to the “Global Restoration Guidelines for Shellfish Reefs” (Fitzsimons et al. 2019), providing a detailed overview of information relevant to the restoration of the European native oyster, whilst adhering to international standards of ecological restoration. Produced by the Native Oyster Network – UK & Ireland in collaboration with the European Native Oyster Restoration Alliance, this handbook aims to be accessible for both small scale, feasibility projects, as well as larger, more established projects, providing access to the knowledge captured within the Networks. To reverse the current trajectory of the European native oyster towards extinction, and restore this once abundant coastal habitat with the many ecosystem services it provides, requires the UK and European community to substantially increase the ambition, scale and number of restoration projects.
