This study aims to develop the design of separation zone, named “Anti-Wildlife Belt”, between habitat of wildlife and agricultural field to decrease agricultural damage by wildlife, especially wild bore and Sika deer. “Anti-Wildlife Belt” is constructed by separation line and its outside and inside space, each of which is required different function as follows; 1) Separation line requires “preventing function to be crossed by wildlife” by physical barrier as fundamental element of “Anti-Wildlife Belt”. 2) Outside space of separation line requires “obstructing function”. 3) Inside space of separation line requires “warning function”.
