Stability achieved in gullies
Thirteen of the 14 gullies treated have achieved some level of stability( stable, mostly stable or partly stable) and may be considered to have moved in the desired direction since remediation work was undertaken( refer to Figure 23 and Table 3).
At the unstable gully( Site 22) initial works included reshaping, gypsum, fertiliser, seed, a bund and two rock chutes. Some remediation works were undertaken on the rock chutes prior to this monitoring and maintenance project. This site received more comprehensive maintenance in 2024. Refer to Figure 29 for details. While the initial response following this maintenance is positive, more time is required to see if the site is on a pathway to stabilising.
Four of the partly or mostly stable sites had maintenance works done: Site 13- landholder in‐kind, Sites 9 and 10 received maintenance in 2024 and Site 14 had two lots of maintenance between 2021 and 2024. Site 12 received early
