Although institutions, regulations and technical measures can be considered as the measures against preservation of natural environment, decision and implementation of efficient environmental preservation plans are called for. Thus, it is indispensable to introduce multi-criteria evaluation methods and obtain the participation and cooperation of local residents for making a highly efficient conservation plan.
First, this study introduces participatory analysis to obtain potential ideas regarding conservation plans from local residents. Second, it evaluates various alternatives to the environmental preservation plan according to three criteria: effectiveness, ease of implementation, and the possibility of residents' participation in the plan.
Finally, it prioritizes the various alternatives using concordance analysis and AHP analysis, and it provides a well-balanced planning proposal for the regional conservation of the natural environment.
