Monitoring the subtidal macroalgae percentage cover in an assessment of the human impact on diving sites in Brittany (France): direct estimation versus photography
International audience The fluctuation in macroalgae percentage cover was used as a bioindicator parameter to evaluate the potential impact of SCUBA divers around mooring buoys. The technical aim of the survey was to try out standardised, rapid and easily reproducible methods to assess measures for...
