- Summary
- In 1992, the US Army Corps of Engineers-Seattle District, placed oyster shell on tidal flats to mitigate for Dungeness crab mortalities caused by dredging in Grays Harbor, Washington, in 1990. Shell placement damaged isolated patches of eelgrass. To help assess the potential for the recovery of eelgrass in plots that may have been significantly affected, eelgrass transplanting experiments were initiated in 1990. Eelgrass was transplanted into 16 ponded areas that were created by the uneven placement of the shell. Transplanting was carried out in spring 1990, and sampling of the survival of the transplants was conducted in August of 1990 and 1991. Quantitative samples collected August 1992 indicated that transplanted eelgrass increased significantly in terms of shoot abundance since transplantation. The variation and rate of increase in shoot abundance among transplant plots can be partially explained by desiccation stress, with deeper ponds showing enhanced growth rate and plant size.
