Chowilla Icon Site - Floodplain Vegetation Monitoring 2018 Interim Report.

Abstract

This monitoring programme was initiated in 2006 and represents the longest continuous monitoring program of the understorey plant community on the Chowilla Floodplain and at any floodplain site in the South Australian River Murray Corridor. The monitoring programme was established to assess the four understorey vegetation objectives in the Chowilla Floodplain Environmental Water Management Plan (Murray-Darling Basin Authority 2012), namely: Objective 5- improve the area and diversity of grass and herblands; Objective 6- improve the area and diversity of flood dependent understorey vegetation; Objective 7- maintain or improve the area and diversity of grazing sensitive plant species; Objective 8- limit the extent of invasive (increaser) species, including weeds. The Living Murray Chowilla Floodplain condition monitoring programme has produced an excellent mid to long-term dataset that has documentated the changes in floristic composition through time and in response to flooding and interventions. Datasets of this nature are valuable to evaluate interventions and inform managers when to undertake interventions to slow or arrest decline in condition. Other monitoring and research is required to better understand the underlying biological processes and physicochemical factors that drive changes or the function the vegetation plays in the landscape. Future research and monitoring activities to inform management of the site are given.
