Omoto on Ishigaki Island, and the vegetation at sites of its growth were studied as part of research concerning the exploration, collection, preservation, and proliferation of rare plants in subtropical forest of Okinawa. The following results were obtained. Heritiera littoralis is usually distributed in mangrove swamps and coastal areas. However, it was found to be distributed also along the streams in Sokobaru (altitude 50-80) upstream of the Miyara River at the foot of Mt. Omoto, Ishigaki Island. Heritiera littoralis at the foot of Mt. Omoto was distributed along the stream mostly in gravel deposits. To date, 174 growths of Heritera littoralis have been confirmed in the entire river basin, and 5 of them were damaged. Also, 10 stumps have been confirmed. Three growth of Heritera littoralis estimated to be the oldest in the river basin have been identified. One was growing intact, but the other two were cut at a high of 1.70m from the ground. One them were dead, and the other was budding. Heritiera littoralis was dominat in the tree layer of two stands, which was chracteristic vegetation consist of many species in the forest of back mangrove and inland. It showed some considerations on the cause where the stand had grown at the foot of Mt. Omoto, it should be studied in future. The colonies of Heritiera littoralis at the foot of Mt. Omoto grew at a higher attitude than the colonies in Komi, Iriomote Island. Therefore, the processes of their distribution and formation of forest stands are extremely interesting, and further studies on the dynamics of their changes are needed. Since Heritera littoralis at the foot of Mt. Omoto on Ishigaki Island shows unique inland distribution, it should be designated as a natural treasure of Ishigaki City. It should further be designated as a natural treasure of the nation similarly to Heritiera littoralis of Okinawa Prefecture or Iriomote Island.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3429"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
