Evaluate the habitat suitable of Eastern Sarus with the Habitat Suitability Index (HSI) together with the Potential Surface Analysis (PSA) by giving weighting value for each indicator by analyzing the relationship between the difference of habitat on Eastern Sarus Crane encounter points by Chi-square test and regression analysis and Analysis the suitability index or SI value by the probability encountering the same species in the different habitat. Results of calculations inform of Ri and Si and had value between 0-1. If the value approaching to 1 indicates that there are very suitable but the value approaching to 0 indicates that there is less suitable.
