SMALL-SCALE SITES
For the small-scale sites, suitably qualified specialists( e. g. soil conservation officers and other experienced practitioners) were engaged to work with landholders and NQ Dry Tropics to devise and write remediation plans. At this early stage, decisions were made around whether the catchment, the gully, or both, would be treated.

Nine of the 19 sites had the gully and at least the immediate catchment treated while five sites had only the catchment treated and at another five sites only the gully was treated, the catchment being in good condition or, for one site, the catchment was a council road.( Figure 4 and Table 2).
During the site visit( s), the landholders were supported by NQ Dry Tropics staff and soil conservation experts to build their understanding of, and capacity to manage, erosion. There was a strong focus on grazing land management
