Farmers finding new uses for versatile drones

People who work with cattle will be able to muster using a drone, but even the most skilled drone pilots with no cattle nous will fail.

That’s the steadfast opinion of veteran helicopter and drone pilot Lyle Gillham, one of the experts who demonstrated the efficacy of drone mustering at each of the two Drones in Agriculture workshops hosted by NQ Dry Tropics recently.

He proved he knew what he was talking about by demonstrating how a lightweight off-the-shelf drone could be used to round up cattle, including beasts that had never seen them before.

At Mt Pleasant Station, Collinsville, and again at Jervoise Station, Greenvale, Lyle was able to introduce the drone to cattle in the paddock, and, in less than 20 minutes, bring them calmly to him.

At Jervoise, he was able to steer the herd past the hayshed where about 30 spectators broke into spontaneous applause.

“Drones will never replace helicopters, but they are another tool the cattleman can use,” he said.

“You can get up high and see where the cattle are in amongst the trees and send the bikes or horses directly to them instead of spending half the day trying to find them.”

He said cattle responded to drones in much the same way as they did to helicopters, but because drones were so much smaller, it was imperative that the operator didn’t sit the drone directly over the cattle and allow them to get used to the idea that it couldn’t hurt them.

He said good technique was even more important with a drone.

“Get up high, see where they are, see where they’re going, then use the drone by dropping down briefly to turn or block them, then get back off them and go up high again quickly,” he said.

Licensing, practicality, versatility and future possibilities were topics covered by the presenters at both workshops.

Chad Nowak, a former international drone racing champion now working for UAS Pacific, talked about the rules and regulations and safe operation of drones.

He said the rules applied even in the most remote locations and strongly recommended people take the time to get training and an appropriate licence.

CEO of OTB spatial, Michael Kaminski focused on the cutting edge applications of the technology including using drones to inspect assets, and using advanced remote sensing software to measure vegetation density for forage budgeting.

He also talked about their application in weed treatment on farms.

NQ Dry Tropics’ staffers Josh Nicholls and Gav Rosetti explained how drones were used to produce imagery and survey data for communications and project planning purposes.

Jervoise Station grazier Greg Jonsson who, with wife Kerry, hosted the second workshop said the technology was impressive and definitely something the next generation would use.

NQ Dry Tropics Senior Grazing Field Officer Josh Nicholls said drones were another tool that would help graziers to move cattle more often, to rest paddocks and retain end-of-season ground cover.

The Jervoise Station workshop was part of the Grazing Resilience and Sustainable Solutions program funded through the Queensland Government’s Reef Water Quality Program and delivered by the Department of Agriculture and Fisheries, Burnett Mary Regional Group, Fitzroy Basin Association and NQ Dry Tropics. 

The workshop at Mt Pleasant Station was hosted by the Landholders Driving change project, funded by the Queensland Government through the Queensland Reef Water Quality Program.

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.
