Aquatic Plant Survey
Aboard Joanne Delage & Ron Burton’s floating barge, Kitty Lloyd, Winona Pugh & Lori James Derry collected samples of lake plants.
We have 8 sites we stop at, and collect plants from 3 depths at each site: 2, 4 & 6 meters. Where you see no photos after the site/ depth location, it means we couldn’t get to that shallow of depth because of the density of plants.
Using plant density rating charts from the BCLSS:
