Biodiversity values of wetlands

Wetlands are important for maintaining biodiversity. They also perform a range of ecological, hydrological and other functions that provide substantial benefits to society. These benefits are known as "ecosystem services".

Wetlands contribute to the maintenance of biodiversity by providing:

• Habitats for many species of plants, birds, fish, amphibians and other aquatic life. The NSW Wetlands Management Policy estimates that 550 species of native plants (including 11 rare or endangered species), 52 fish species and 194 species of birds, amphibians and reptiles are found in NSW wetlands.
• Breeding and nursery areas - some wetlands provide essential reproductive conditions and nursery areas for aquatic fish species. Floodplain wetlands provide breeding opportunities for migratory water birds.
• Drought refuges - wetlands provide food and shelter for fish, water birds and other animals in times of drought.
• Links between aquatic and terrestrial food chains - the exchange of water and nutrients between the plants and animals on land and in the water.
