Since the environmental assessment technique has never been established in Japan, an impact of the environmental restoration project cannot be justified objectively. Habitat Evaluation Procedures (HEP), which is one of the most applicable methods in evaluating the environments in the U.S.A, has been recently introduced to Japan together with the investigation of its applicability. This paper aims to examine whether the environment condition and its compensatory mitigation projects can be evaluated by using HEP or not. As a case study, the environmental conditions of the spawning ponds for the Tokyo salamander, which disappeared by constructing the Chiba-Togane road, and the substitutive ponds for spawning created by the Japan Highway Public Corporation (JH) as the compensatory measure for disappeared habitat area were evaluated by using HEP. Moreover, the study also assessed how this compensatory measure can contribute to the conservation of environments around the road through the comparison of the results evaluated for these ponds.
