If we set frame of study site freely, the moved distance will change freely. Then we made a square that starting and ending points of hare track are the both ends of a diagonal line of the square. Moved distance per area = 2L / l2. Here, L is hare track length ; 1 is a length between starting and ending points (this is the diagonal of the square). When we convert the moved distance (m) into that of 1ha, the converter equation is as follows : surveyed track length (m) : x (m) = l (m) : 100√2(m). Here x is a moved distance converted into 1ha area, 100√2(m) is a length of the diagonal line of 1ha area. we can compare the moved distance, which is an index of hares' favorable habitat, of many different surveys., Article, 信州大学教育学部附属志賀自然教育研究施設研究業績 46: 15-17(2009)}, pages = {15--17}, title = {雪上足跡を用いたノウサギの好適な環境の把握}, volume = {46}, year = {2009} }
