Monitors continue good work
A community-based water quality monitoring group established in 2019 continues to prove its worth to scientists, collecting data on how much sediment and nutrient run-off is flowing into the Great Barrier Reef from the Bowen, Broken, Bogie (BBB) catchment, around Bowen and Collinsville.
Belmore work complete
Remediation work carried out at Belmore Downs on seven active gullies covering 19ha is now complete. It’s been a big job and it will have a big impact.
Data collection fun
Portable laser scanners, such as handheld 3D scanners and mobile lidar systems, have transformed the 3D mapping industry. Their advantage over typical 3D mapping technology includes mobility, flexibility to be used in a wide range of environments and industries, and are easy to use.
Hands-on result
Barry Collett’s unique position as owner operator of an earthworks business, and manager of Todsure, the family business, meant he could take advantage of his experience to undertake the remediation works and subsequent maintenance works.
Regaining land
Earth works were aimed at halting the progress of a linear hillslope gully, about 15m wide and 0.8m deep, consisting of a series of actively eroding gullies. Remediation involved the construction of a 250m long diversion bank and a 20m water spreading structure at the outlet of the bank.
Tried and true
Erosion repair works aimed to halt an active 2m deep gully located at the base of a small hill with head cuts slowly making their way up-slope. The soil is a sodic duplex with 20cm grey topsoil and deep dispersive mottled red and yellow clay subsoil derived from decomposing granite.
Real collaboration
An important tenet of NQ Dry Tropics’ extension program — collaboration with key stakeholders, including landholders, to work towards solutions for NRM outcomes. It leads to deeper insights, fresher perspectives and delivers results.
LDC in a nutshell
Between 2017-2020, the Burdekin Major Integrated Project (Landholders Driving Change) completed 25 gully remediation projects, five large-scale and 20 small-scale sites.
Gully sweet spot
Sick and tired of seeing topsoil disappear down gullies and creeping gully heads gobble up productive land, graziers have been working hard to fix them. The trick is finding the sweet spot — low cost interventions that stop further erosion and enable grazing land to be reclaimed.
