This is what I do...

Basically we do benthic surveys of vegetation (Braun-blanquet scoring technique)and animals (throw trap collection method):

This is a picture of the trap in the water at a shallow site.

In this picture, you cana see the sweep nets we use to collect animals caught in the trap. As you can imaagine, this semi-destructive sampling stirs up the bottom sediments pretty good.

Another picture of working on the trap.

Those two photos are of the quadrats we use for the vegetation surveys. Each species receives a score from 0.1 to 5 based on the approximte cover that species represents within the quadrat.

All the pictures were taken in Card Sound, south Florida.
