CERMES (Centre for Resource Management and Environmental Studies (CERMES) Faculty of Science and Technology, The University of the West Indies, Cave Hill Campus, Barbados) describe 3 zones in the Barbados Fringing Reefs (Baldwin et al., 2019; Maclean and Oxenford, 2016):<\/p>\n

Reef Flat:<\/strong> Closest to shore: eroded reef framework with macro- and turf algae<\/em><\/p>\n

Crest and coalesced spur zone:<\/strong> Middle segment: solid reef (no grooves): macroalgae with fire corals (Millepora spp). Porites spp., <\/em>P. clivosa and some <\/em>A. palmata regrowth<\/em><\/p>\n

Coral spur and grove zone:<\/strong> Seaward edge: living coral spurs and sand grooves<\/em><\/p><\/blockquote>\n

The CERMES Reef Flat zone<\/span>\u00a0 is equivalent to the Reef Flat and the Diploria-Palythoa zones combined<\/span> in Lewis (1960)<\/p>\n

The CERMES\u00a0 Crest and coalesced spur zone<\/span> is more or less equivalent to the Reef Crest Zone<\/span> in Lewis (1960); Lewis includes a portion of the grooves; his definition relies of the slope of the bottom – it ends (and the Seaward Slope begins) when, proceeding seaward,\u00a0 the bottom starts to slope downward.<\/p>\n

The CERMES\u00a0Coral spur and grove zone<\/span> is\u00a0 equivalent to the Seaward Slope Zone<\/span> in Lewis (1960) but inlcudes some of the Reef Crest zone of Lewis as described above.<\/p>\n

In the CERMES classification, Fringing Reefs are less than 5 m depth, and their definition of “Fringing Reef” applies essentially to physically continuous structures out to 5 m depth. Lewis adds a “Reef Front” zone, which lies just outside of the continuous structures and extends to the beginning of his Deep Water Communities, which he described as another zone; Lewis’s invesigtaions extended seaward to approx. 30 m depth.<\/p>\n

The three CERMES zones are in general, readily distinguished in aerial photos of the coastal zone.<\/p>\n
