To improve the breeding success of the Golden eagle, restoration programs for foraging habitat using line-thinning have been tried in some sites of Tohoku region, Japan. These restoration programs, however, were not always effective because candidate sites have not been selected based on ecological characteristics of eagle and its prey animals. As a result of our study to clarify the long-term effect of line-thinning on the density of the Japanese hare which is main prey of eagles, we adopted two points essential for extracting the candidate site having high potentiality to increase sustainably the hare density: 1) selecting the forest with high density of hare, which is possible to increase hare density effectively, 2) selecting the forest where understory would be dominated by herbaceous species after cutting, which is possible to increase hare density sustainably. By overlaying the potential maps of hare density and herbaceous plant biomass, we selected the candidate forest for restoration of foraging habitat within 24 eagle’s home range in Kitakami highland, one of core habitat of the Golden eagle in Japan. Using candidate forest map and breeding ratio of each pairs, we propose the forest management plan to coexist with the habitat restoration of the Golden eagles.
