A group of 25 people including landholders, local earthworks contractors and representatives from Glencore, Whitsunday Regional Council and Department of Agriculture and Fisheries (DAF) attended the Scottville Cluster Group field day. They are pictured at a sign near the six participating properties. acknowledging the partnership between the NQ Dry Tropics’ LDC project and Glencore.

Scottville mob performs a ‘labour of love’

A group of landholders from Scottville, near Collinsville, banded together two years ago to address erosion issues on their properties. 

Dubbed the ‘Scottville Mob’, they represent six neighbouring properties, and from the outset, had a clear line of sight to:

  • understand the causes of their erosion hotspots, as well as the extent of the gully networks and likely rate of expansion; 
  • design solutions to repair eroding gullies;  
  • get on with the job of fixing the problem areas; and
  • remove grazing pressure to allow vegetation cover to establish on remediated areas.

Dividends paid in knowledge and skills for everybody involved

Barry Collett

Grazier Barry Collett said being part of a cluster group had reaped dividends in building knowledge and skills for everybody involved.

“NQ Dry Tropics brought us together in a coordinated way, including experts, to help guide us,” Mr Collett said.

“As a result we’ve learnt a lot about remediating and preventing erosion, and landscape function.

“When we come together there’s always good discussions, because a one size fits all approach doesn’t apply to fixing erosion problems. 

“Each property has had its own unique issues and therefore what worked on one place wasn’t going to work on another.

“Now the works have been completed, it’s really good to revisit the sites and see what’s being done and how the works are holding up.

“It’s been a great learning experience. Our discussions are now focused on grazing land management, and how to best improve pasture and soil health.”

A chance to tackle a big problem with help from friends

Stanley Fordham

Stanley Fordham, of Emohruo, said being part of a cluster group enabled him and his wife Judy, to address erosion issues and improve ground cover.

“For us, erosion has been a big problem for a long time. We’ve always had the will to fix it but its been cost prohibitive,” Mr Fordham said.

“When NQ Dry Tropics came along with the LDC project it meant we were eligible to access some funds and resources and I’m very thankful for that.

“During wet seasons the water comes tearing down the ridge and runs straight into Pelican Creek taking with it valuable soil.

“If you can block a gully and hold that water back in the country, you’re going to keep water and soil on the paddock, and that’s a whole lot better than seeing it run out into the ocean.

“The works we have done will keep water and soil on the paddock, and that means we can now put more effort into improving pasture and soil health.”

Valuable opportunity to design solutions to problem areas

Isabel and Garry Sloane

Isabel Sloan, of Hillview, said she and husband Garry valued the opportunity to be able to help design the solution to the problem areas on their property.

“Many heads are better than one, and my husband and I appreciated the consultative approach by all stakeholders,” Mrs Sloan said.

“As graziers, we run our farms a little bit differently so it was important that what was done on-ground suited our individual land management requirements.

“We were also able to choose the local contractor we wanted to use. It was important to us to support local businesses.

“By doing a lot of the work ourselves meant we reduced labour costs. Physically, it was very hard work, but we learnt so much while doing it, and as a result we’re very proud of our efforts and the results.”

Experts helped the Cluster Group to achieve

Through the LDC’s integrated activity areas of Grazier Support and Landscape Remediation, the Scottville Cluster Group was able to access expert assistance to help identify remediation options and guide implementation. 

Bob Shepherd

Department of Agriculture and Fisheries (DAF) principal extension officer (grazing land management) Bob Shepherd provided expertise to help the cluster group develop cost-effective designs to remediate gullies and other property erosion features to reduce soil erosion.

Works included surface water diversion banks, installation of rock chutes and gabion baskets, reshaping of erosion areas, and seeding topsoil on reshaped areas.

Glencore provided in-kind support through sharing expertise and knowledge in landscape remediation techniques, and also provided the majority of rock for the rock chutes.

All on-ground works were carried out by local contractors. Landholders provided some in-kind machinery and significant labour.

Common features

Gully restoration options have a number of features in common:

  • Arresting upstream migration of gully heads.
  • Stabilising banks, typically by battering and re-shaping.
  • Establishing cover, a perennial grass and cover crop.
  • Removing grazing pressure, typically by fencing to allow a vegetation cover to establish.
  • Diverting upstream flows (at least temporarily) to avoid further degradation.
  • Planning for subsurface flows and soils prone to dispersion if they are a risk.

Reef regulations - grazing, standard conditions

  1. For land in good or fair condition (more than 50 per cent ground cover at 30 September), continue using measures to maintain land condition.
  2. For land in poor condition (less than 50 per cent ground cover at 30 September), steps must be taken to improve land condition.
  3. For land in degraded condition (less than 20 per cent ground cover at 30 September), steps must be taken to improve land condition OR prevent areas from further degrading or expanding.
  4. Keep records of measures taken and also of agricultural chemicals, fertiliser and mill mud or mill ash applied to land.

The LDC project monitors four gully sites (represented in this table) with gold standard equipment and analysis, carried out by CSIRO.

Results have been compiled in a preliminary report from Bartley et al (2020), with the final report expected to be released by the end of 2020. The preliminary report shows all four sites have indicators of improvements, notably the Strathbogie and Mt Wickham sites.

*The Exploring New Incentives activity area has provided an opportunity for graziers to adopt improved land management practices through a range of activities. For some of these properties, it was the first time they signed contracts for on-ground works.

Figure 1. Total fine sediment reduction by project type and erosion source. Inset shows the proportion of the total project area for each project type.

These estimates have been calculated using two methods: 

1) The pollutant reduction component of the Alluvium/Great Barrier Reef Foundation (GBRF) investment tool for hillslope and streambank erosion management projects; 

2) The Reef Trust Gully Toolbox method for gully erosion management projects. The LDC Water Quality Report 2020 (Waterhouse et al., 2020) highlights that a number of assumptions underlay these calculations, therefore these figures should be treated as the best available estimate of sediment reductions to date.

Preventing sediment from reaching the Great Barrier Reef

Each wet season sediment is washed into local waterways and out to the Great Barrier Reef (GBR). 

Most sediment is very fine, and can stay suspended for a long time and can travel great distances. Valuable topsoil is lost from production, and increased concentrations on the reef can be harmful to seagrasses and corals. 

Landholders in the BBB have completed 69 on-ground water quality practice changes, and it is estimated that these have contributed a fine sediment reduction of 6,154 tonnes per year from reaching the GBR. 

Of this, approximately half of the sediment savings are attributable to grazing land management changes on hillslopes and streambanks, and the other half as a result of gully remediation treatments across a broad range of scales, as shown in the graphs above. 

The table below also highlights the relatively small area of intervention in the gully management projects compared to the large sediment savings that these can achieve - 60 per cent of the sediment savings over only 4 per cent of the project area.
