It is found in some particular habitats in the alpine and "pseudo-alpine" zone of the high mountains in northern Honshu. In the first paper the authors aimed to examine the floral communities of the habitat of Erebia niphonica based on a field survey. A total of over 100 sites of the habitats is recognized, and it emerges that these habitats are located on five particular floral communities. In this second paper it is also studied that the relations of the vertical distribution pattern of Erebia niphonica and vegetation zone lacking the subalpine coniferous forest in the regions of heavy snowfall on the Sea of Japan side of northern Honshu, on the basis of ecological angle. Horizontal distribution of Abies mariesii, a major tree in subalpine coniferous forest and Erebia niphonica is also discussed.
