Table 2 Assessment criteria for the Z. marina beds
From: Bay-scale assessment of eelgrass beds using sidescan and video
Score | Cover | Quality |
|---|---|---|
1 | Continuous bed | Green, luxurious eelgrass with very little or no epiphyte load (epigrazers common) |
2 | Continuous bed with bare patches | Green leaves with medium to high density epiphyte load, leaves not pulled down by this load |
3 | Patches or clumps of leaves, no continuous bed | Epiphyte cover so high that no leaf surface is visible (bent over stunted/fragmented leaves covered in algal material) OR majority of leaf surface is black or brown OR eelgrass remnants with the presence of benthic algal mats |
4 | No live eelgrass | No live eelgrass or eelgrass remnants |
