Understanding how this alteration will interact with fertilization to affect transplants is essential for future restoration planning. We examined the individual and combined effects of nutrients (ambient vs. repeated addition) and burial (control vs. increased frequency and intensity) on the performance and biomass partitioning of transplants of the seagrass <jats:italic>Cymodocea nodosa</jats:italic> at two sites within a north‐western Mediterranean meadow.

Our research demonstrates that sediment fertilization ensures rapid colonization of restoration sites, providing <jats:italic>C. nodosa</jats:italic> plants up to eight times larger than controls in one growing season. However, it also indicates that interaction of increased burial and nutrients reduced the gain in terms of vegetative expansion and depressed vertical growth, making plants more vulnerable to subsequent disturbances. Therefore, seagrass restoration practitioners should account for changes in sediment elevation at transplanting sites when planning restoration programs and carefully evaluate the opportunity of applying fertilizers in sites subjected to greater sediment accumulation to avoid failure.</jats:bold></jats:p> Effects of Sediment Fertilization and Burial on <i>Cymodocea nodosa</i> Transplants; Implications for Seagrass Restoration Under a Changing Climate Restoration Ecology |
