MLA – weed project

Holistic approach to managing priority weeds THIS three-year project will develop five demonstration properties within the BBB catchment to trial and promote holistic approaches to the management of priority weeds. It will also adopt neighbour-friendly collaborative...

MLA – grazing

Producer Demonstration sites LDC has been successful in securing funding from MLA to establish two Producer Demonstration Sites (PDS).  MLA partners with producer groups to achieve improved business productivity and profitability outcomes.  The MLA PDS program...

GRT case study

LDC helps to manage GRT problem   LDC is working with Eungella and Crediton landholders to manage Giant rat’s tail (GRT) grass. A case study on how graziers near Minani in the Pioneer Valley have been managing the invasive grass is an interesting read. The...

GRASS

Help available to tackle degraded land THE Grazing Resilience and Sustainable Solutions (GRASS) program aims to support graziers to improve poor and degraded land by delivering one-on-one support by developing tailored land management plans and identifying actions...

M and E is fun

M&E – it’s not always dull MONITORING and evaluation (M&E) can be fun… yes, truly. It gets to be a lot of fun when you persuade certain members of the LDC team to install moisture probes. These photos and videos, taken by the project’s...

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.

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.
