Sheppard","doi":"10.5479/SI.00775630.574.16","DOIUrl":"https://doi.org/10.5479/SI.00775630.574.16","url":null,"abstract":"In the 1960s and 1970s the biology and geology of the Grand Recif of Tulear, (now Toliara) in southwestern Madagascar, was thoroughly studied and reported. Toliara is the largest city in the south of the country, and the Grand Recif offshore provides both artisanal fisheries and coastal protection to the growing regional capital. Substantial \u0000research on the comparatively pristine reef was described in a volume of Atoll Research Bulletin in 1978. Since then, published scientific study of this reef has been largely \u0000lacking. The present study compares the condition of the Grand Recif of circa 40 years ago, with that seen in a brief resurvey undertaken in 2008, on transects corresponding to \u0000some of those documented previously. The trend has been of severe degradation; hard coral cover on the fore-reef slopes has declined substantially, and there has been a near \u0000total loss of the “architectural species” in particular. Coral has been replaced to great extent by fleshy algae. Observations also indicate severe decline on the broad reef flat, back reef and lagoon areas. Perhaps most seriously for the local fisheries and human communities, is that the fore reef is almost depleted in reef fish today. \u0000Comparisons are made of coral cover, coral morphological types and fish trophic structure with other reefs in southern Madagascar, which are not located near large \u0000human populations. Although a rise in mean sea surface temperature has occurred throughout the region of approximately 1oC over this 40 year period, which is probably a contributing cause of decline throughout, the Grand Recif is in much worse condition than most of the more remote reefs with which it is compared. It is suggested that the main reasons for the substantial decline in the Grand Recif over the past 40 years lies in the fact that the region’s population has grown substantially, there is a complete lack of any resources management, heavy overfishing, and no pollution control, resulting in \u0000massively increased discharges of sewage, sediments and other pollutants.Reef condition today is unrecognisable from that described in the 1970s. Unless far-reaching and effective management interventions are adopted to safeguard the Grand Recif the remaining ecosystem services upon which Toliara and its population depend will soon all but disappear.","PeriodicalId":34898,"journal":{"name":"Atoll Research Bulletin","volume":"574 1","pages":"16"},"PeriodicalIF":0.0,"publicationDate":"2010-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70938540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Colony densities and size class distributions were determined from censuses within belt transects at the same sites. All three methods showed statistically significant differences in total coral cover and relative abundance of coral genera among three habitats (fore reef, back reef, and lagoon). Mean coral cover was sparse (< 1.6%) on both the fore reef, which was dominated by massive and encrusting growth forms of Porites, and in the lagoon (< 1.2%), which was dominated by Pocillopora. Mean coral cover was highest on the back reef (> 13.5%), which was dominated by Montipora. All taxa showed habitatspecific differences in colony density while the two most widespread genera, Porites and Pocillopora, showed differences in habitat-specific size class distributions. Midway has the lowest system-wide and habitat-specific mean coral cover of the seven reef systems in the NWHI that have been surveyed with similar methods during a comparable time period, which is likely related to its history of human use and modification. Bleaching history, disease prevalence, crown-of-thorns seastars, marine debris, larval recruitment, and alien benthic invertebrates are discussed as other influential factors shaping the observed coral community.
