* size in hectares

** SP = sediment laden plug
    BR = bare root 

*** + = net increase in eelgrass coverage
       0 = no change in eelgrass coverage
       - = net decrease in eelgrass coverage


1Transplant was initially adversely impacted by an unknown source of
sediment and was deemed unsuitable.  The translant later recovered
from what was determined to be a one time sedimentation problem.

2Transplant was experimental due to dense beds of the exotic muscle
Musculista senhousia which inhibited the growth of the transplant.

3Transplant was completed in an area deemed unsuitable.  Insufficient
coverage required the construction of a remedial site.  Monitoring
continues at both the initial and remedial sites.

4Transplant was experimental.

5Multiple sites.
