A million plants and counting
More than one million native plants will be used to vegetate the ponds, wetlands, rain gardens, swales and restored creeks and channels being built as part of the Project.
Over recent months, the project team has been working with representatives from Conservation Research, Transport Canberra and City Services and the Woodlands and Wetlands Trust, to develop a list of just over 100 preferred species.
Conservation and biodiversity are very important but plants also have to suit the local environment, have a history of success in similar locations and meet the relevant guidelines.
The team also had to make sure that the plants chosen are suited to the different environmental conditions in each of the water treatment options – from dry to completely submerged and everything in between.
The proposed list includes rare species as well as plants with heritage and cultural value to the local Aboriginal people. Some plants have been selected because they are the only known food source for certain butterflies or frogs.
Construction is not expected to start until mid-2017 but, due to the large quantity required, the search for plants begins now. Also, some rare plants may be difficult to find and will have to be propagated and tested for resilience.
