showed a linear corridor connecting two local populations.
However the population size is considered not to be sufficient
to maintain a healthy local population; it is ranked as “serious
danger of extinction.” Also, the two sub-local populations in Mt.
Ashitaka and Mt. Kenashi which consist of Fuji local popula
tion are considered isolated from other local populations.
Therefore, it is recommended 1) to prepare an appropriate zon
ing plan, which could protect the habitat of Mt. Ashitaka, Mt.
Kenashi, including a corridor to Tanzawa and Fuji, and on
wards via Mt Kenashi to South Alps, and 2) to reinforce this
corridor’s functionality. For the Japanese serow, the population
size in Fuji and Tanzawa is considered sufficient to avoid in-
breeding and loss of genetic diversity. Thus the outcome of the
research can be summarized as follows: “There is a need for
ecological networks in Fuji and Tanzawa regions for Asiatic
black bear, but not necessarily for Japanese serow.”
