Xuan Thuy National Park is the first wetland in Vietnam that register to participate in international convention on wetland conservation (Ramsar). It is a region that has a high level of biodiversity and also the shelter for various migratory birds, in which including species of Black-faced spoonbills (Platalea minor), a species listed in the EN (endangered) according to the IUCN rating scale. The result found that number of P. minor was 60 individuals from 2002 to 2006, reach to 74 individuals from 2005 to 2006. However, number of P. minor reduced to 30 individuals in period 2011-2012
there are three habitat conditions in the research area and the research found that shrimp pond habitat is suitable with P. minor life, making breakwater and round up shrimp hatching have affected to habitat of P. minor. Some ecological-environmental factors affecting to species distribution of this species in Xuan Thuy National Park were identified. From that point of views, this study has applied GIS and remote - sensing technology to detennine some adapted living areas (point), the results in total of 78 study points showed that: 7/78 points extremely adapted, 11/78 points adapted, 5/78 points moderately adapted, 14 /78 points less adapted, and 41/78 points were not adapted with behavior of Black-faced spoonbills. This study is a fundamental method to detennine strategy for conservation of some endangered migratory birds and approach method for biodiversity conservation in Vietnam.
