Characteristics A separate window opensReferences

These are the waters in the vicinity of the mouth of the Shigenobugawa River in the city of Matsuyama. The river mouth area, which includes river-mouth tidal mud flats, is visited by snipe and plover, with relatively high populations during the migration seasons of spring and fall. Here at least 1% of the minimum estimated population of Numenius phaeopus has been recorded, along with 0.25% of the minimum estimated population of lesser sand plover, grey-tailed tattler, ruddy turnstone, and dunlin. Common redshank, and Far Eastern curlew also have been recorded here. In addition, this area is habitat to a highly diverse range of species of benthic animals (Ministry of the Environment, 2001).
