Figure 14. Land Condition Scores for large-scale gully remediation Site 5 over three years of monitoring.
The LCAT scores at Site 5 reflect the success of the revegetation in the catchment contrasted with the limited work in the gullies( Figure 14). As for Site 2, the high results for LCAT 2 in the revegetated catchment indicate that the good land condition was reached prior to the monitoring program. LCAT 3 is in the catchment further upslope away from the gully. The LCAT score for the treated catchment was likely to have been around 50 / 100 prior to treatment in 2020. Site 5’ s LCAT 4( Figure
15) is situated at the transition zone between the intense revegetation work in the catchment and on to the rock chute and the‘ badlands’ that did not receive treatment. In the last set of three photographs in Figure 15( view north) some of the scarps are visible. In the initial treatment the scarps received some ameliorants without soil disturbance. Some maintenance earthworks were undertaken on some of the scarps that continued to erode.
