The alpine plants distribution patterns at Mt.
Kusatsu Motoshirane were described and some related environmental
factors were investigated. At the Karagama volcanic crater, higher
area of the crater wall is mainly covered with Abies veitchii
and Betula ermanii, and lower area is covered with Pinus
pumila and Vaccinium uliginosum. This distribution
pattern is contrary to the general pattern of these species.
Continuous air temperature measurement revealed that the higher
area was warmer than the lower area during the winter season.
