Property mapping | Landholders Driving Change

Property map helps in property management

A property map can assist with property management and planning including:

  • identifying areas on the property that are sensitive areas such as streams, wetlands, waterways, or any other place where water coming from the livestock operation comes into contact with clean water;
  • identifying soil types and other characteristics, such as slope, that can be helpful in making management decisions like grazing plans; and
  • analysing and monitoring property infrastructure, land resources and groundcover.

FarmMap4D

Computer mapping software package that equips landholders with new skills and knowledge in on-line digital farm mapping. FarmMap4D has a number of innovative products and tools of use to graziers to assist them in planning, monitoring and managing grazing enterprise decisions i.e. Vegmachine, Forage. Training provided 1:1 with landholder or via group setting via LDC approved trainer. Three-year registration complimentary for participants.

Phoenix Mapping

Computer mapping software package with workshops delivered by AGDATA’s trainers and Agforce. Program integrates easily with the PHOENIX suite of products which is a comprehensive and integrated financial and farm management system.

Google Mapping

Property mapping utilising freely available Google Earth and accessing relevant and up to date Queensland Government data through Queensland Globe. Delivered by DAF, NQDT staff or external providers.

Landholders Driving Change provides extension services and technical support to users of FarmMap4D. Landholders interested in using FarmMap4D can contact:

KEQ #1

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.

*GLMWW = Grazing Land Management Wire and Water

KEQ #3

*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.

KEQ #4

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.

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.
