This Toolbox is a guide to targeting, designing and implementing gully and stream bank erosion control activities in Great Barrier Reef (GBR) catchments. This third edition builds on 7 years of implementing these activities in multiple programs and it aims to inform the ongoing efforts to reduce the amount of fine sediment and associated nutrients delivered to the GBR lagoon. Sub‑soil erosion, predominantly from gullies and stream banks, contributes the vast bulk of the fine sediment load delivered to the GBR. The large area and extensive erosion in GBR catchments, and the limited resources available, make it important for erosion control to be targeted to cost‑effective sites and implemented using best practice based on best available information. Landholder support and site maintenance increase the likelihood that sediment reductions will persist over the long term
