The healthof w ildlife species depends on safe habitats, which consist of both living and nonliving elements. As a result, egrets ecological safety can be understood as the maintenance of ecological suitability in spite of anthropogenic impacts. The safety of the habitats is the primary issue in egrets ecological safety assessment. This paper reports on the results of a study of two major breeding habitats and ten typical foraging habitats of egrets along the Xiamen coast, locations selected to assess the ecological safety of the egrets which live in that area . Breeding habitats cover the entire land area and the intertidal area of Dayu and Jiyu islets which have been designated as the Xiamen National Nature Reserve. The foraging habitats cover all types of w etland along the Xiamen coa
