Total Study Site | The total Upper Florida Keys study site, includes 13 habitat types. |
Aggregate Reef | Aggregate reef larger than 1 hectare (ha), contiguous reef, lacking sand channels. |
Colonized Pavement | Contiguous to patchy pavement, lacking spur and groove channel formation, presence of macroalgae, hard coral, gorgonians, and other sessile invertebrates, dense enough to obscure underlying rock. |

Not Classified | Areas where habitat has not been classified. |
Pavement | Contiguous to patchy pavement, lacking spur and groove channel formations. |
Pavement with Sand Channels | Alternating linear sand and pavement formations, perpendicular to reef crest. |
Pavement with Seagrass | Contiguous to patchy pavement, lacking spur and groove channel formations with seagrass. |
