| Research Abstract |
Our results suggested that bears used marginal areas of their habitat disproportionally such as forest edges, riparian forest and some crops where currently unmanaged and much closed to human settlement. It indicates that bears become susceptive to meet conflicts with people in those landscapes, The probable habitat-use distribution map estimated by resource selection functions (RSF) represented that unmanaged lands being used as forestry and agriculture in the past and some attractants are the main predictors for habitat use of black bears. Further, we could identify some aggregated areas used by bears that would have a high-risk for bear survival in the season. These results provide fundamental information to conduct more effective mitigations in human-bear conflicts based on more reliable estimation, and to contribute to conservation planning included landscape management, while lethal control is still the major implementation in wildlife management in many parts of Japan.
