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.”
