The Shire of Kalamunda has planted more than 12,000 native sedges in Poison Gully, High Wycombe.
Adding sedges into the channel along Poison Gully aims to stabilise and reduce erosion of the banks, and provide more habitats for insects, frogs, mammals and other wildlife using the waterway.
Shire chief executive Rhonda Hardy said the sedges strategy in spring provided the best chance for growth and reduced the risk of erosion.

“This site is a real community asset. It is an important wildlife corridor and also contains a threatened ecological community,” Ms Hardy said.
With help from EcoJobs and the Green Army team, the Shire of Kalamunda has undertaken mass plantings of pale rush, knotted club rush and jointed rush sedges along the High Wycombe section of Poison Gully.
Poison Gully and its catchment is in the foothills and the scarp of the Darling Range.
The creek starts in Stirk Park, at the top of Kalamunda Road, and traverses the northernmost section of Mundy Regional Park as it heads west.
Leaving the shire, it flows into Munday Swamp on the Perth Airport site, a significant wetland and Aboriginal heritage site.
The vegetation is described as open woodland of jarrah, marri and banksia with fringing woodland along creek beds of flooded gums and swamp paperbarks.
The site forms a natural buffer between the environment and homes in the region and provides locals with direct access to the natural environment.
Ms Hardy said environmental work to improve and protect Poison Gully was ongoing and any supporters would be welcome.
