The large-scale ranch was managed under light feeding condition of 0.25 cattle-unit/ha, and the vegetation was consisted of 3 vegetational types such as the natural forest with short herbs, Acacia shrubland with long herbs and scattered Acacia shrubland with short herbs. The management of vegetation in the large-scale ranch was evaluated as “Excellent” to “Fair” conditions. The low grazing pressure of 0.25 cattle-unit/ha could maintain a good vegetation conditional in Kenya highland. On the other hand, the small-scale pastoral area was used under heavy feeding condition of 2.26 cattle-unit/ha, and its vegetation was evaluated as “Fair” to” Poor” conditions. Such overgrazing as 2.26 cattle-unit/ha could cause poor vegetational condition in Kenya highland. It is considered from this case study that “Lower grazing pressure in a large-scale pasture and highly grazing mobility” seem to be the important strategy for wildlife conservation. The feeding system of the large-scale ranch in Kenya highland is considered as the excellent case of land use for wildlife conservation in dry/semi-dry areas.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"帯広畜産大学","subitem_publisher_language":"ja"}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"帯広畜産大学","subitem_rights_language":"ja"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11877585","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13485261","subitem_source_identifier_type":"PISSN"}]},"item_5_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Hirata,
