Full description

The back reef habitats of three outershelf reefs (Ribbon Reef No. 10, at the Cod Hole, Chicken Reef and Turner Cay), one mid-shelf reef (Lizard Island) and one inshore reef (Great Keppel Island) were surveyed for juvenile hard corals between October 2006 and May 2007. Densities of juvenile corals were estimated by counting the number of colonies of <50 mm diameter in a 34 x 34 cm (0.12 m²) quadrat with a scale bar attached. Between 7 and 33 haphazardly placed quadrats were sampled at each reef. All juveniles were assigned to one of two size classes (<20 mm and 20-50 mm), which allowed the effects of colony size on detectability to be assessed. Juveniles were identified to the lowest possible taxonomic level, usually genus.Photographs of each quadrat were taken using an 8.0 megapixel Canon Powershot S80, except at the Cod Hole site where a 5.0 megapixel Canon Powershot A95 was used.Each quadrat was assessed by a single observer in the field and the image of each quadrat was assessed by two independent observers in the laboratory. No observer surveyed the same quadrat using both methods. The substrate in each image was rated from 1 (flat) to 10 (complex with many holes and crevices) to assess whether substrate complexity accounted for any differences between the two methods.
This study was undertaken to investigate whether analysis of digital still camera images provided estimates of density and taxonomic composition of juvenile corals that were comparable to estimates obtained from visual census in the field.
