Kanna-Nagashi. J. mandshurica is often observed as riverside vegetation and it
inhabits places with abundant soil moisture. Since Kanna-Nagashi removes the soil
from the mountain slopes, the slopes were flattened to become gentle slopes with
rough texture and concave. Because of these unique topographic features, a
riverside-like environment with abundant soil moisture was generated.
J. mandshurica is characteristically distributed in a large area at present (Koarai
et al. 2011). The eco-tope elements model in Kanna-Nagashi site are shown in
Fig. 7.14.

The author produced landscape ecological map combined with three dimensional
vegetation structure and micro landform classification. Sample of landscape ecological map of the north foot of Mt. Dogo is shown in Fig. 7.15. The author
