Imperata cylindrica Beauv. var. major C. E. Hubb., Panicum repens L., Paspalum conjugatum Berg, and Sporobolus diander Beauv. which are common species in all locations grow on Iriomote Island, but different species appear in the moist and dry areas. In the pasture, the planting succession seems to proceed in a short time because the shrubs of Pandanus odratissimus L. f., Psidium guajava L., Mallotus japonicus Muell. -Arg., Macaranga tanarius Muell. -Arg. and others have carried out an invasion uppon the pasture about three years after the grass grows and makes two layers between these plants and Imperata cylindrica Beaub. var. major C. E. Hubb. On the meadow which does not weed, some invader species also appear soon after the herbage grows. The grassland Imperata cylindrica Beauv. var. major C. E. Hubb. is divided into three types : grazing plant community, non-grazing plant community and low grazing plant community. If left uncared for, it changes to shrub. Sporobolus diander Beauv. is low grazing plant type and palatability by the cattle especially decreases when plants begin to ear. The grazing plants totalled 163 species, inclusive of grazing species, non-grazing species and unclear species. The grazing plants of Grameae were twenty-five species which were the most of species in many families. Following were Compositae. Leguminosae, Malvaceae, Cyperaceae, Euphorbiaceae and others respectively. By way of grazing, the grazing plant was classified into three types and was divided into smaller categories by grazing traces (Fig. 3).","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/20.500.12000/3801"}]},"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.
