and Nypa fruticans. Rare distribution site of mangrove tree
species. Geographically rare distribution site of mangrove forests.
Representative and endemic distribution site of mangrove forest
ecosystems. High diversity of mangrove forest ecosystems. |

Funaura-shicchi and its inflowing rivers |
Three large and small rivers (Nishida-gawa, Hinai-gawa
and Yassa-gawa) flow into Funaura-wan (bay), where well-developed
mangrove forests are found. In particular, Funaura is the northernmost
distribution site for Nypa fruticans. In the forests, waterways
and outer tidal flat, many tropical fish species are found, and
sharks and rays wander into the bay at high tide. The mangrove forests
and the surrounding areas support 5 species listed in the RDB of
Japan or Okinawa Prefecture (Caridina brevicarpalis, Uca triangularis
triangularis, Utica borneensis, Philyra iriomotensis and Birgus
latro). The inflowing rivers and the riparian land areas support
5 species listed in the RDB of Japan or Okinawa Prefecture (Neocaridina
brevirostris, Macrobrachium shokitai, Geothelphusa minei, Ryukyum
yaeyamense and Birgus latro) and 4 Coenobita species
designated as National Natural Monuments (Coenobita cavipes,
C. rugosus, C. brevimanus and C. violascens). Thus the
entire river basin is important. |

The site encompasses extensive mangrove wetlands
which are densely inhabited by Terebralia palustris. Tidal
flat area supports a large number of Plicarcularia bellula
and Listriolobus riukiuensis. |
