Abstract

Reefs were chosen for low algal coverage and the dominance of sponges and corals in terms of area coverage, and were grouped into channel patch reefs and soft coral-sponge patch reefs. Shallow patch reefs (<4 m depth) were selected from low-altidude, natural-color aerial photographs based on size, color, and location. Field survey techniques were employed to evaluate the viability of photo-interpretation of reef types. Two survey techniques used to evaluate the patch reefs were species presence and absence lists, and belt quadrats. The belt quadrat technique can account for the density of dominant benthic sessile invertebrates as well as species area coverage, and thus is a better method for characterizing patch reef communities. This field method allowed for the quantitative grouping of patch reef communities based on observed natural color characteristics. -from Authors
