PROJECT DESCRIPTION

In April 2019, Southern Habitat began Stage 1 of slope stabilisation works of the embankment of Gaerloch Reserve, Tamarama. 

This Reserve is highly visible and forms part of the famous Bondi to Bronte Coastal Walk.

 

OUR WORKS

Due to its steep and rocky terrain, we initially erected a woven mesh fence to provide a deterrent and exclusion zone to minimise public access.

 We then mowed the turf and applied herbicide twice, before removing any remaining weeds by hand.

 Trenches were excavated and coir logs were installed and secured by hardwood stakes.

 390 plants were installed onto the slope after pre-slitting the jute mat to minimise disturbance.  These consisted of endemic coastal headland species such as Dune Fan-Flower (Scaevola calendulacea), Warrigal Spinach (Tetragonia tetragonioides) and Pig Face (Carpobrotus glaucescens).

 A 13mm drip irrigation system was installed at 400mm contour intervals above the surface of the jute mat.

 A maintenance period of 6 months followed practical completion, which included watering, weeding, rubbish removal, fertilising, pest and disease control and replanting.
