Wetland Surveys For Aquatic Biodiversity at Violet Vale Station
This project documents the aquatic fauna and quantify the water quality of wetlands on Violet Vale Station. These surveys targeted fish, crustaceans and turtles and provides an indication of the inherent biodiversity value of the wetlands and serve as baseline data to monitor future management actions.
This is the first study to document the aquatic fauna and water quality of the expansive floodplain wetlands on Violet Vale Station. Typically, wetlands are diverse ecosystems that support high levels of biodiversity and perform essential ecosystem services. Importantly, wetlands act as nursery grounds for a number of commercially important fish species such as Barramundi and Mangrove Jack; sustaining natural recruitment and also recreational and commercial fishing industries.
This delicate ecosystem is vulnerable to degradation by feral herbivores such as cattle, pigs and horses as well as invasion by semi-aquatic and aquatic weeds. It is important to establish a baseline inventory of species inhabiting the wetlands to monitor the effect of management actions such as destocking, exclusion fencing and weed removal.
Survey methods are designed to maximise species detection and are repeatable to ensure that follow up surveys can be completed in future, subject to available funding.
