Currimundi partnership banks on fresh approach to erosion
  • Friday 10 April 2009

The local community has joined Sunshine Coast Council to create an innovative and environmentally-friendly retaining wall along the banks of Currimundi Lake at Noel Burns Park.

The project, the first time that coir fibre logs have been used to address erosion issues at the lake, was a joint effort involving council’s environment branch, Conservation Volunteers Australia and the Currimundi Catchment Care Group.

Division Three Councillor Keryn Jones said the logs offered a number of advantages for projects of this type.

“The logs are a biodegradable coconut fibre and they can run along the natural contour of the banks, beneath any undercutting that has occurred and around exposed tree roots,’’ Cr Jones said.

“With the aid of clumping plants that hold the banks together while the coir breaks down, the banks can be stabilised and protected from erosion. This is a good option for projects of this scale, in a fragile ecosystem that includes fish and crab breeding areas.”

Coir fibre logs:

are easily installed and blend naturally into the environment over time
assist with sediment retention and help mitigate the effects of waves
provide protection until natural vegetation is established.
Cr Jones said the trial project has come about thanks to strong community partnerships and federal funding support.

“Council had tremendous support from the Currimundi Catchment Care Group and the conservation volunteers.”

The project was funded by a Commonwealth Government grant of $6,732 and in-kind support from council of $6,230.
