Yaegl Nature Reserve protects a large and important area of floodplain paperbark forest and an area of coastal saltmarsh, each of which is listed as an endangered ecological community. The reserve also provides important habitat and winter food resources for a range of native fauna, including the threatened grey-headed flying-fox, the grey-crowned babbler and the brolga.
Yaegl Nature Reserve also contains an Aboriginal keeping place for the Yaegl people.
