| Outline of Final Research Achievements |
Seasonal changes in the spatial structure of deciduous forest may exert a large influence on foraging habitat selection of the Japanese golden eagle. In this study, we compared between characteristics of foraging habitat of eagle before and after leafing by airborne laser scanner, and estimated potential foraging area within home-range for building up conservation scenario of this species. Before leafing, foraging habitat was consisted of large forest gap covered by snow, and potential foraging area was widely distributed within the home-rage. After leafing, the size and shape score of forest gaps in which eagle foraged were larger than those of gaps which was selected randomly. Eventually, potential foraging area within the home-range was decreased from before leafing to after leafing. We propose that it is essential to conserve the large gaps after leafing and/or to create larger forest gap in coniferous plantations by forest-thinning for increasing foraging efficacy of this eagle.
