‘Bright spots’ for estuary management in temperate Southern Australia

Estuaries are a transition zone for fresh and saline water and sediments, providing a range of ecosystem services for the local population, infrastructure and industries located in their environs. They are also governance transition zones where jurisdictions often overlap and focused attention is often lacking. As Australia’s population continues to expand, particularly in the south, estuaries are increasingly becoming popular locations for settlement due to their picturesque surrounds and accessibility for water-based activities. This results in expanding human and industry activities and pressures along estuaries and adjacent coastal settings impacting ecosystem service delivery. The absence of dedicated national and state estuary legislation in addition to decades of poor land and waterway management decisions paints a ‘doom and gloom’ picture for temperate southern Australian estuaries. Against this backdrop, there are number of estuary ‘bright spots’ where natural resource management bodies in strong partnership with local actors are moving forward in overcoming challenges to estuary conservation. Using case studies, this paper describes the key elements for effective estuary management that can lead to improved estuary health.
