The Limestone Coast is home to around 16,000 wetlands, and is widely recognised as the wettest part of a dry state.

Prior to European occupation, almost half the area in the region was home to wetland habitats. Worldwide, wetlands are disappearing three times faster than forests, and only 2.5% of the original wetland extent in the Limestone Coast remains.

What are the benefits of wetlands?

Wetlands are important for healthy landscapes and communities in many ways:

  • Help to retain water in our landscape and recharge our aquifers

  • Store carbon and regulate our climate
  • Provide summer grazing
  • Provide habitat for pollinators, as well as predators of insect pests such as ibis
  • Remove pollutants from waterways
  • Hold cultural significance
  • Assist in flood mitigation
  • Provide habitat for many threatened flora and fauna species
