bottoms in the photic zone with more than 10 %, but less than 90 %
coverage of both hard and soft substrata. Perennial algae covers at least
10 % of the seabed and more than other perennial attached erect groups. Out
of the perennial algae, perennial filamentous algae constitutes at least
50 % of the biovolume.
