Interpretation of an aerial photograph of a field fire (a grass fire) at Kushiro moor

Abstract

A field fire occurred at Kushiro moor in April 1985 and its influence on vegetation was investigated by means of aerial color photography. The investigation clearly revealed that the degree of destruction due to a fire's ability to progress can be limited by rivers, artificial structures, and thick forests which work as barriers to limit spread. The influence on vegetation was investigated by aerial photography 6 months following the fire. However, the investigation could not specify the extent of damage. This is due to the fact that the fire did not exert a significant influence upon the subsurface of the earth which had been frozen at the time of the fire.
