Summary of watering actions with expected outcomes for the year relevant to the Basin Matter In 2014–15, the Commonwealth Environmental Water Office (CEWO) contributed to 83 watering actions, with a total of 1041 GL delivered across the Basin. A total of 65 watering actions specifically targeted riverine and wetland vegetation (Appendix A). Of these, 15 watering actions had expected outcomes associated with vegetation within and/or immediately fringing river channels, including its maintenance and/or improvement as well as, in several cases, to prevent encroachment by terrestrial plants. A further 20 watering actions focused mainly on improving the condition or recruitment of particular species, mostly riparian trees (e.g. River Red Gum, Black Box) and Lignum. The remaining watering actions had expected outcomes relating to vegetation diversity in floodplain and wetland ecosystems. Seventeen of the watering actions conducted by CEWO in 2014–15 for which expected outcomes were identified for vegetation, occurred in the Selected Areas being considered by the Basin Matter evaluation for vegetation (i.e. Edward–Wakool, Goulburn, Gwydir, Lachlan, Murrumbidgee and Warrego–Darling; Table 1). Monitoring of vegetation diversity responses occurred with respect to eight of these watering actions (Table 1). Expected outcomes for these watering actions were mostly to maintain or promote the extent and diversity of wetland plant communities (Table 1).
