A more accurate understanding of the impact stormwater runoff has on the Karaaf Wetlands will be known with the pending release of two separate assessments of the unique ecological system.
Commissioned by the Surf Coast Shire, the first study by renowned botanical field ecologist Doug Frood will evaluate the environmental condition of the wetlands and include an audit of invasive and native species, areas experiencing dieback and other issues relevant to stormwater flows, freshwater intrusion, inundation, infrastructure or land use.
Urban water specialists DesignFlow are leading the second assessment that focuses on the suitability of the stormwater system and constructed wetlands at nearby housing estates and identifying short and long-term interventions to improve their functionality.
Stormwater runoff can help Shire understand development prospects
“These assessments will help community and government to get a clear consensus of what a healthy Karaaf looks like. It will provide valuable insights into how urban development can impact natural ecosystems,” Surf Coast mayor Libby Stapleton said.
“Once the data gathering is complete we will have a better picture of what issues exist. It will provide an insight into what the next steps should be. This information will feed into the development of an integrated water management plan that reflects our commitment to preserving our environment now and into the future,” said Stapleton.
About Karaaf Wetlands
Recognised as one of the region’s most productive carbon sinks, the 320-hectare wetlands are a hyper-saline salt marsh that provides critical habitat to a wide range of species. Those species include the migratory waders from North Asia and the orange-bellied parrot.
The new federal government made a $1.9 million election pledge to improve the ecological state of the wetlands. They have focused on improving the retention and filtering of stormwater runoff. They are reducing the number of pollutants, or potential for pollutants, to reach environmentally significant areas in the system.
This commitment will be put forward for the Federal Government’s first budget.
