Unitywater has a Site Management Plan in place to guide and inform maintenance and care of the land at Yandina Creek.
How we will look after the site
- We must protect this land, as we do with all other Unitywater sites. We have established arrangements for routine land management tasks, including maintenance of fire breaks and access trails, periodic weeding, mosquito treatment, feral animal management and the clean-up of any litter.
- Unitywater routinely inspects the site to monitor the re-establishment of the wetland environment, including the vegetation, local waterways and soils. We now have monitoring programs established with:
- Birdlife Southern Queensland (quarterly surveys on birdlife)
- University of Sunshine Coast (fish habitat study)
- Griffith University (vegetation dynamics, soil and nutrient studies)
- Verterra Ecological Engineering (monitoring of water quality, vegetation and general site condition).
This monitoring allows us to better understand and track both the wildlife and plant life and other benefits of the wetland re-establishing at the site.
Plants and wildlife at the site
The building blocks of vegetation recovery can already be seen on the Yandina site, and as the wetland environment matures these plant communities should expand in the years ahead, including:
As the wetland matures in the years ahead, a range of birds and animals should return to the site. We are already seeing initial improvements at the site. Check out the vlog episodes for more information.

Unitywater is pursuing nutrient offsetting as a low-cost alternative to treatment plant upgrades that also enables us to protect human health and the environment. At the Yandina Creek site:
we will make the most of the natural processes by re-establishing the wetland environment and allowing tidal water from the river to enter parts of the site.
the wetland plants and micro-organisms in the soil will take up the nutrients like nitrogen and phosphorus from the tidal water.
we calculate how much nutrients the site will take up and this is incorporated into its treatment plant environmental licence limits.
These wetlands are estimated to remove 5.3 tonnes of total nitrogen per annum.
The end result? We meet our licence limits, public health is safeguarded, the environment is protected and we cater for growth, all thanks to a sensible strategy of letting nature take its course.
