Many landholders who live and work alongside creeks, streams and rivers will know it can be very rewarding as soils tend to be rich in nutrients and organic matter which makes flood plains so attractive for agriculture. These same areas however can become a very destructive environment when we experience high flow events which overtop riverbanks and inundate floodplains.
Floodwater can become very devastating as it can destroy fencing, remove topsoil, erode riverbanks, deposit cobble on the flood plain, destroy the riparian vegetation and in the worst case can lead to the loss of stock or even life. Having a healthy riparian buffer can provide shelter for stock, habitat for birds and bees, shade for aquatic life while reducing the amount of pesticide and fertiliser that can make its way into the river from agricultural practices. Having healthy riparian vegetation of reasonable width along your river during a flood event can provide better bank stability, slow flood water and even catch floating debris before it hits your fence.
Riparian revegetation is by far the most cost effective long-term investment when it comes to creating resilience in a river system while enjoying many of the benefits which come with having a healthy ecosystem.
Make sure you contact your Local Government Authority before undertaking any works in or along a river.
