I insisted on a pre and post dredge monitoring program in the lagoon. I think Vittor did did the work. They monitored the borrow areas before dredging and at least 2 or 3 times after, I think the 2nd monitoring event was one year post dredge. Post dredge they compared areas of similar depth. Benthic invert community diversity and density was statistically similar to non-dredged areas of similar depth at one year post dredge.
