Prioritisation key to tackling gully erosion in the BBB
The Bowen , Broken and Bogie ( BBB ) catchment near Bowen and Collinsville delivers nearly a quarter of the total fine sediment load entering the Great Barrier Reef lagoon . About 65 % of this comes from gully erosion , which is why gully remediation in the BBB is a major ongoing investment priority .
In recent years , NQ Dry Tropics has increased its capacity to prioritise , design , deliver and monitor major gully remediation works . Prioritisation is critical because it helps guide investment .
Since the Landholders Driving Change project started five years ago , NQ Dry Tropics staff , in partnership with Griffith University , have mapped 22,311 active gullies in the BBB with a cumulative active area of 4620 hectares .
The mapping methodology , which estimates fine sediment yield , was validated on-ground by staff from both organisations during a series of site visits in November 2021 .
