Dynamic features of the subalpine meadow
development on Mount Aizukomagatake, central Honshu, Japan.
Sadao TAKAOKA E Yoshihiko KARIYA
The historical development of subalpine
mesic meadows was examined on Mount Aizukomagatake which is in a Japanese snowy
region. The age and size structure of Abies
mariesii trees growing in and around
the meadows were studied to discover the characteristics of vegetation dynamics
in snowy subalpine areas. Soil profiles were observed to estimate growing
conditions of A. mariesii trees and
to reconstruct the long-term change in the meadow size. The results of the
study suggest that the dynamism of subalpine meadows is affected by the
temporal scale at which data are gathered. The meadows have reduced for the
last millenniums. They have remained almost stable for the last 300 years, and
have sometimes been invaded by A.
mariesii saplings over the last 40 years.
