摘要

As seagrasses are not available with commercial nursery stocks, the removal of a large amount of plant materials may damage donor populations. We evaluated the recovery of the eelgrass Zostera marina following the removal of entire plant patches (0.01-0.49 m~2) at the edge and interior of an eelgrass bed in Rongcheng Bay, Shandong Peninsula, China, through a field experiment. We investigated the shoot density, morphology and growth of recovering plants following excavation. We found that the removal of entire small patches with excavation areas ≤0.25 m~2 in the interior of the eelgrass bed was the most suitable strategy for harvesting donor plants of Z. marina. Small patch excavation (<≤0.25 m~2) was able to promote asexual reproduction in recovering plants, and their shoot density and morphology equaled or exceeded those of natural plants＜7 months after harvesting. These results indicate that Z. marina plants have a strong capacity for resilience from physical disturbance through rhizome elongation in the harvested area.
