The following two issues remain to be dealt 
with: 
i) Improvement of the precision of the land 
cover classification Figures for changes in the 
wetland surface that include erroneous 
classification, even if they appeared in the 
classification image, were unavoidable. In order 
to investigate the effects of park development 
regulations, it is necessary to improve the 
accuracy of the classification method. 
11) Increase the favorable/unfavorable factors 
considered in the biotope 
Indepth environmental surveys carried out with 
consistent precision are few. In order to promote 
landscape analysis and the determination of 
biotopes, it is necessary to make more readily 
available relevant surveys, reports and numerical 
data.

The authors would like to express their thanks to 
the Eastem Hokkaido National Parks Wildlife 
Office of the Environment Agency, without its 
support and assistance, especially in the 
gathering of resource material and field surveys, 
this study would not have been possible.
