<p>The species composition, habitat condition, and geographical distribution pattern of the subalpine to alpine meadow （Trollio-Ranunculetalia acris japonici Ohba 1973） on the northern part of the Ushiro-tateyama mountain range were investigated. Based on species composition, the Trollio-Ranunculetalia acris japonici in this region was classified into 7 associations, 1 community, and 3 subassociations. In this area, with heavy snowy climate, variety of Trollio-Ranunculetalia acris japonici were found, depending on altitude, topography （slope type, slope inclination）, in sites with high snow accumulation such as avalanche slopes and concave slope. Characteristic association were found in serpentine areas. It suggests that the diversity of the Trollio-Ranunculetalia acris japonici in the northern part of the Ushiro-tateyama Mountain range is caused by the snowy environment and serpentine. Additionally, the proportions of the geographical distribution pattern of the species that constituted each vegetation unit differed as a function of altitude and topography. The Carici brevisquamae-Hedysaretum vicioidis established close to the ridgeline above the forest limit had a high proportion of circumpolar elements, while other vegetation units that were established above the forest limit tended to have a higher proportion of Pacific elements. Conversely, the vegetation units that were distributed below the forest limit had a higher proportion of lower montane elements and low-altitude species. This difference in the geographical distribution pattern as function of altitude and topography suggests that vegetation history resulting from climate change should be considered when discussing factors that affect the distribution of the subalpine to alpine meadow.</p>

<p>The species composition and habitat condition of the alpine desert (<b><i>Dicentro-Stellarietea nipponicae</i></b> Ohba 1969) on the northern part of the Ushiro-tateyama mountain range were investigated. Based on species composition, the <b><i>Dicentro-Stellarietea nipponicae</i></b> vegetation in this region was classified into 6 associations, 2 communities, and 2 subassociations.</p><p>On the leeward slope, <b><i>Saxifragetum merckii idsuroei</i></b>, <b><i>Cardaminetum nipponicae</i></b> and the <i>Polygonum nakaii</i> community are established on rectilinear to concave slopes, <i><b>Veronico-Polygonetum weyrichii</b></i> is established on rectilinear to convex slopes, and the <i>Draba shiroumana</i> community is established on convex slopes. <b><i>Sedo rosei-Saxifragetum bronchialis funstonii</i></b>, <b><i>Dicentro-Violetum crassae</i></b> are established on the convex slope on the windward side. <b><i>Cerastio-Minuartietum vernae japonicae</i></b> is established on the convex slope on any aspect. Most of the vegetation units were found on gravels, <b><i>Sedo rosei</i></b><i><b>-Saxifragetum bronchialis funstonii</b></i> and the <i>Draba shiroumana</i> community were mainly found on rock shelves. The <i>Polygonum nakaii</i> community and <b><i>Cerastio-Minuartietum vernae japonicae</i></b> were found in serpentine areas. The <i>Draba shiroumana</i> community was found in limestone areas.</p><p> In this region, the presence of <b><i>Saxifrago-Cardaminetalia nipponicae</i></b> could be explained by slope aspect and slope type. Alliances and vegetation units depended on more specifically defined environments, such as the stability of surface gravels and soil chemistry in the serpentine and limestone areas for the <i><b>Minuartietalia vernae japonicae</b></i> of this region</p>
