ASTONBROOK ESTATE UPGRADE

Astonbrook Estate in 2020

Evolve Environmental Solutions commenced work in 2013 at Astonbrook Estate Carindale. Located at Carindale, the Astonbrook Estate is a 47-lot residential subdivision spanning Spring Creek. A tributary of Bulimba Creek, Spring Creek is aptly named after the groundwater springs that daylight in the Creek’s ferned banks and provide the Creek with its primary water source. Spring Creek sits within a sub-tropical riparian system, and functions as a key biodiversity corridor linking the expansive Belmont Hills Reserve to the greater Bulimba Creek catchment.

Containing a diverse mix of native flora and fauna, including the Locally Significant Ornate Rainbowfish (Rhadinocentrus ornatus), Spring Creek is vital to the intrinsic and strategic biodiversity function of both Carindale and the broader south-east Brisbane bioregion.

Evolve Environmental Solutions began by removing all declared weeds in the riparian corridor of Spring Creek. Predominantly covered in Cats Claw vine, Lantana and Camphor laurel trees, the site was particularly sensitive due to the substantial Rainbow Fish habitat living in the creek.

A bridge crossing was installed at the southern end of the corridor, paying particular attention to erosion and sediment management. Weekly water quality tests were performed onsite, whilst Rainbow Fish monitoring occurred on a monthly basis. After initial weed management, over 40,000 native trees and shrubs were planted onsite and nesting boxes were installed.

The return of native animals to this corridor has been exciting, as white cockatoos, gliders and water lizards are now frequently seen. Visitors to the area are advised to keep an eye out for the 5.0m python that resides near the bridge.

Astonbrook Estate in 2015

Eight years on and this space is flourishing. The unusual approach at Astonbrook involved planting strangler figs in the crook of the existing Camphor laurel trees that lined the banks of Spring Creek. This 10-year strategy seems to be paying off.
