Various of reef near Miyako Jima.  \u003cbr/\u003eThe Nansei Archipelago is a chain of sub-tropical islands off the coast of Japan and home to some of the world's most diverse marine environments. \u003cbr/\u003eIn 1996 the region was selected as one of the World Wildlife Fund's (WWF) global 200 eco-regions or biologically outstanding terrestrial, freshwater and marine habitats.   \u003cbr/\u003eIn an effort to promote conservation of the archipelago's marine environments, the WWF is currently surveying biodiversity priority areas in the region.  \u003cbr/\u003eSmall brightly coloured fish swim amongst coral. \u003cbr/\u003eBut this eco-system in the Nansei Archipelago  is under threat... from a star fish. \u003cbr/\u003eThe Crown of Thorns starfish, gets its name from its spiky protective armour. \u003cbr/\u003eIt has a big appetite and devours (eats) coral. \u003cbr/\u003eThe Crown of Thorns starfish has been very successful in this area over the last six years and has devastated many reefs according to environmentalists. \u003cbr/\u003eThe WWF Japan is carrying out a survey to measure important 'eco-regions'. \u003cbr/\u003eCollaborating on the project is an alliance of Japanese reef monitoring organisations, independent specialist researchers and local communities. \u003cbr/\u003eYasumura Shigeki of WWF Japan is one of the project leaders. \u003cbr/\u003eHe explains that the survey is taking place in over 23 locations between Yakushima (approximately 60km / 37 miles from the most southerly point of the Japanese main land) to the island of Iriomote (around 200 km / 124 miles from Taiwan in the East China Sea.)    \u003cbr/\u003eHowever Yasumura says that Crown of Thorns Star Fish is just one threat to the Nansei archipelago marine habitats.... others include soil erosion, water pollution and climate change.    \u003cbr/\u003eThe survey began in 2006 and is due to be completed in 2009,  when the data gathered has been analysed and a map outlining the priority areas will be produced.    \u003cbr/\u003eHowever it is not an easy task .... waves, currents, the complexity of reef structures and the under water environment itself make surveys extremely physically challenging.  \u003cbr/\u003eThe dynamic nature of the reefs characterised by shifts in coral population and coverage also makes it difficult to distinguish natural from man-made changes. \u003cbr/\u003eKajiwara Kenji is a marine biologist and part of a team conducting the WWF survey. \u003cbr/\u003eHe explains that the ocean floor is photographed in sections of metre square, each from the same height. \u003cbr/\u003eHe says \"in each region of the survey a total of twenty one locations are selected in which two kinds of survey are conducted. The first method is conducted in (six) fixed areas marked by positioning a metal stake driven into the seabed. The marker means that each year we can accurately survey exactly the same area.\"  \u003cbr/\u003eNeither the science behind the project nor the chosen methodology with which the survey is being conducted is particularly new.  \u003cbr/\u003eWhat is new however, is the application of this particular methodology to this region and it is hoped that the project will provide a useful data base for future research.  \u003cbr/\u003eYasumara Shegiki hopes that in five to ten years, the same areas can be surveyed again. \u003cbr/\u003eThis will allow researchers to compare the results, analysis of which will help give a better understanding of the complex effects of global warming. \u003cbr/\u003eIt will also enable the marine biologists to determine if the coral population has recovered from the recent devastation caused by the Crown of Thorns Star Fish. \u003cbr/\u003eIt is hoped that the WWF survey will provide even more data that will help in the fight to preserve the coral regions of Japan in the future.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex justify-between'\u003e\n\u003cbutton aria-expanded='false' aria-label='Read
