A series of surveys were carried out on the northern reef at Balaclava as part of a UNESCO/COMARAF training workshop on coral reef ecology and management, held 1-12 October 1990.Line transects (20 m long) estimated percent cover of benthic attributes (Att.), non-colonised substrate (Coral rock, Dead coral, Rubble, Sand) and other benthos. Corals were identified to species where possible and the number (No.) of each colony was recorded. The maximum lateral dimension (Dia.) of each coral intercepted by the tape and an extimated of coral injury (Inj.) were also recorded.Belt transects were used to restimate composition, density and size frequency distribution of corals (12 x 0.6 m, divided into 4 m segments). Fish data recorded a tally of each type (species, family) observed as present or passing through 2 belt transects (50 x 4 m). Belt transects (100 x 0.6 m, 100 x 2 m, divided into 10 m segments) were also used to record the densities of 4 urchin species within 0.3 m of the tape for Echinometra mathaei and Echinostrephus mollaris; and within 1.0 m for Diadema setosum and Tripneustes gratilla. To train participants in basic survey methods and analyses using a local reef. Balaclava is also known as Baie de l'Arsenal.Coral species: Acropora grandis; Alveopora mortensoni; Astreopora myriopthalma; Echinophyllia orpheensis; Favia flexuosa; F. paliida, F. speciosa, F. stelligera, Favia sp.; Favites abdita; Favites sp.; Fungia repanda; Galaxea fascicularis; Goniastrea pectinata, Goniastrea sp., Goniastrea spat; Montipora danae, M. grisea, M. incrassate, M. spumosa, M. tuberculosa; Mycedium elephantotus; Pavona cactus, P. decussata, P. varians, P. venosa; Platygyra daedalea; Porites cylindrica; Porites massive; Porites nigrescens; Porites rus.Fish families: Acanthuridae; Chaetodontidae; Labridae; Lethrinidae; Lutjanidae; Pomacentridae; Scaridae; Serranidae; Siganidae.Echinoderm species: Diadema setosum; Echinometra mathaei; Echinostrephus mollaris; Tripneustes gratilla.
