Project Overview

The Guanaba Creek Revegetation project restored 8 hectares of severely eroded and weed‑invaded riparian corridor along a private property in the Guanaba Valley. Working closely with the landholder, Wildscapes delivered a full-scope riparian restoration program that stabilised creek banks, dramatically improved water quality, and created a functioning wildlife corridor connecting two isolated bushland remnants on the property.

The Challenge

Years of cattle grazing to the creek edge had destabilised the banks, causing significant erosion and sediment runoff into the waterway. Exotic pasture grasses and Lantana had colonised the riparian zone, eliminating native vegetation and removing the root systems needed to hold the banks together. During flood events, large sections of bank were collapsing, threatening the property's fencing and infrastructure. The creek had lost its ecological function as a wildlife corridor and water filtration zone.

Our Approach

Riparian zone fencing to exclude cattle from the creek corridor — a critical first step allowing natural regeneration to commence and preventing further bank destabilisation from livestock trampling and grazing pressure.

Emergency bank stabilisation using coir logs, rock chutes at erosion hotspots, and immediate planting of native sedges and rushes to bind soil and prevent further collapse during the establishment phase.

Systematic removal of exotic pasture grasses and Lantana using targeted herbicide application, with careful attention to avoiding spray drift into the waterway and protecting any remnant native plants.

Strategic revegetation using 2,800 locally‑sourced native plants across 24 species — including riparian specialists such as Melaleuca bracteata, Casuarina cunninghamiana, Lomandra hystrix, and native sedges matched to the creek's hydrology.

Direct seeding of native grasses and groundcovers across the broader riparian zone to accelerate ground cover establishment and reduce erosion risk between planted tube stock.

Quarterly monitoring visits over two years tracking bank stability, plant survival rates, weed reinvasion, and water quality indicators — with adaptive management adjustments made at each visit.
