In 2016 prior to watering, the Twentysixth Street site was dominated by black box trees, lignum, nitre bush, and samphire. The first watering at the site occurred in 2017.
By 2020, the delivery of environmental water over successive watering years encouraged a pair of swans to nest. There was also a notable increase in native duck species and other birdlife – 13 waterbird species and 18 woodland bird species have been recorded at the site during surveys. During frog call surveys, six frog species have been recorded.
Significant numbers of black box seedlings germinated following the 2022-23 flood. A small amount of environmental water was used in 2023-24 to support the survival and establishment of the seedlings. Water has been delivered in autumn 2025 to continue to support these seedings, which are now thriving.
