Abstract
This paper aimed to assess the actual situation of environmental conservation projects for protecting roadside's natural environment and the ecosystem all over the Japan. Creating habitat for specific creatures and biotope for various species is being carried-out as the part of environmental conservation projects for restoring the affected environment of past developments. Recently, these projects have been actively implemented. However, the actual state of how these projects were conducted has never been fully reviewed. Therefore, field surveys and consultations to the developers who were in-charge of environmental conservation projects were conducted for analyzing the actual situation and clarifying the problems. As a result, it was concluded that it is necessary to establish the manual for developing habitat and biotope because most of these projects have not established any conservation goals and few have made plans not considering the harmony with the environment.
