漫湖は、いろいろな生き物の棲みかです。
漫湖は河口干潟であり、満潮時には水で満たされ、干潮時には泥干潟が広がります。
泥干潟では、無数のカニ類がハサミを振り、「トントンミー」と呼ばれているトビハゼ類が飛び跳ね、泥の中にはゴカイや貴重な貝類が生息しています。干潮時には、それらの豊富な底生生物を食べるために多くの水鳥が集まり、忙しく干潟を歩き回る姿が見られます。
満潮時には、鳥たちはマングローブの上で羽づくろいをし、水面下では、マングローブの複雑な根の周辺に小魚たちが群れていることでしょう。
豊富な栄養を含む干潟、漫湖には、豊かな生態系があり、多くの生き物がつながりあって暮らしています。
Manko is the oasis of Waterbirds and aquatic life
Lake Manko,lacated at the confluence of the Kokuba and the Noha River which run through Naha City and Tomigusuku City,is surrounded by roads,parkd and houses except for partially remaining natural shore.
The area of the Ramsar Convention Register of Wetlands starts from the upstream between the briges of madanbashi and Ishihiyabashi and ends at the downstream located at the Naha Ohashi Bridge.The designated area is 58 hactares with a mud flat bottom.
Lake Manko is a staging site for migratory birds such as snipes and plovers.Some migrate from Russia to Australia,covering the distance of 12,000 km.Not only herons like Great Egret and Grey Heron,but also such rare birds as Common Redshank and Black-faced spoonbill fly over to Lake Manko.
Lake Manko not only hosts mangroves lacated near the northern limit of its distribution,but also a reed field,a coastal wetland forest,and Okinawa’s largest tidal mud flat.
There are abundant creatures for birds to feed on and a variety of benthos exist in the lake.Those are the kinds only to be seen in a mud flat and a particular species of shellfish in danger of extinction has also been found.
