Lower Yarra BioDiversity Linkages Project Stage 1

In 2010, the City of Stonnington started one of the biggest regeneration pro­jects in the Yarra River’s recent history – the Yarra River Biodiversity Project. The Yarra River acts as a wildlife corridor (or ‘green freeway’) for many differ­ent animal species. Making your way along the Yarra River you may encoun­ter several of the animal and birds that share this riparian habitat. If you are lucky you may see a noisy flock of Yellow-tailed Black cockatoos .

Stage 1 – Ephemeral Wetland – Entracon
An ephemeral wetland system was constructed during Stage 1 of the Yarra River Biodiversity Project to treat stormwater run-off from the Toorak Village catchment. The wetlands remove sediment and filter pollutants from storm­water including nutrients such as phosphorous and nitrogen. Vegetation in the wetland also helps to treat the water before it is discharged into the Yarra River, as well as providing habitat for birds, animals and fish.
The bicycle path has been upgraded and a pedestrian boardwalk has been installed, winding through the newly planted indigenous vegetation.

Stages 2 and 3 – Shared Pathways – Entracon
Stage 2 included the construction of a series of bioretention ponds with inte­grated walkways; widening of the cycle path, and improved seating to help people interact with the surrounding environment.
Stage 3 included improved shared pathways, seating and viewing sites as well as increasing levels of biodiversity with indigenous native revegetation works.

Stages 4,5 and 6 are planned and set for completion in 2017
