The City of Kwinana is salvaging a large amount of excellent quality bushland topsoil from a development site in Mandogalup, currently being cleared, to assist in the long-term rehabilitation of land at the current WasteStream site on Thomas Road.
In a first for the City, 'excellent quality bushland topsoil' from the development site will be translocated to a place where it is hoped the seed and soil organisms contained within it can survive and grow, contributing to better long-term ecological outcomes for Kwinana.
The now cleared donor site was home to Banksia Woodlands, listed as an endangered ecological community under the Environmental Protection and Biodiversity Conservation Act in 2016.
Mayor Carol Adams said she shared the community's dismay at the destruction of a large amount of these woodlands at the site.
"Our preference is always to ensure that the environmental value of these endangered woodlands is protected and preserved for future generations to come," Mayor Adams said.
"Unfortunately, in this instance we were unable to protect the bushland, so we are attempting to salvage what we can,' she said.
In a first for the City, the topsoil from the development site, which has been tested and deemed 'excellent quality bushland topsoil', will be translocated and given a second life, contributing to better long-term ecological outcomes for Kwinana.
"The topsoil at the Mandogalup site is embedded with seeds from established Banksia Woodlands, along with beneficial soil micro-organisms," said Mayor Adams.
"It is hoped that by transplanting this valuable resource, the City will enable current and future generations to regenerate local or endemic species at a far greater rate than would otherwise be possible," she said.
WasteStream has identified a suitable site at their facility over layers of rubble and other inert waste. Placing this biologically rich soil across an area requiring revegetation is an expression of hope that much of the City's biological wealth will survive. The City will closely monitor this site to determine whether a similar application at other sites requiring revegetation would be beneficial.
