Seagrass restoration is increasingly being highlighted as a way to respond to global seagrass decline. However, restoration of intertidal seagrasses is challenging due to the dynamic nature of the environment, and to date, many restoration attempts have been met with poor success and high variability. Successful restoration efforts are largely attributed to the planting technique, site selection and planting scale. This study aims to provide insight into the effectiveness of different planting techniques used to restore intertidal seagrass via seeds in-situ. Using Zostera muelleri seeds, we trialled three planting techniques at four potential restoration locations across Western Port, Victoria; biodegradable hessian bags, biodegradable pots, and Dispenser Injection Seeding. Seeds were planted in circular split-plots within the intertidal zone to compare techniques whilst accounting for within site heterogeneity. Site characteristics were collected to allow inter- and intra-site comparisons. Shoot density, seed germination and growth were variable between methods and locations, suggesting that techniques are closely related to site selection. These findings highlight the suitability of different planting techniques for restoring Z. muelleri seeds intertidally. We reveal how to optimise restoration potential through strategic selection of site dependent techniques and contribute to the upscaling of Zostera spp restoration more broadly.
