This study, we focus on criteria and factors that support habitat selection of Eastern Sarus Crane after released back to the nature for applied to the model of habitat suitability index (HSI). HSI is a mathematics model that represents to ability of the habitat to support the reintroduction of wildlife species. Criteria and factors in the model to represent the interactions of habitat characteristics associated within wildlife species. This model is a multivariate statistic or a combination of mathematical equations and used for basic decide to habitat assessment. The result has been shown to prediction of the quality and suitability of the wetlands which can be support to population of Eastern Sarus Crane that will be release in the future and get information for conservation and wetland management to prevent or mitigate conflicts between the local communities and government.
