Impact of exclusion fence
Trends in production and performance
AUSTRALIAN Wool Innovation, in partnership with Soils For Life, has established a long-term project to collect evidence on trends in production and environmental performance on wool-growing properties within predator/ exclusion fenced areas of central Queensland and north-eastern New South Wales.
The wool industry is frequently called upon to provide evidence that wool-growing is contributing to environmental benefits such as healthy soils, biodiversity and the recovery of threatened native species.
Predator/exclusion fencing is increasingly being used in the wool industry to manage feral animals and improve control of total grazing pressure.
However to date, no project has investigated the production and environmental effects of before, during and after erecting a predator/ exclusion fence.
“Unfortunately, most scientific studies of primary production have used the arrival of Europeans in Australia as the baseline against which to compare today’s landscape health. However, the introduction of cluster fencing provides a much more current baseline for assessing the effects of contemporary wool production,” said Angus Ireland, AWI program manager, fibre advocacy and eco credentials.
The object of this five-year project is to showcase the improvements that arise from wool producers having increased control of their operations in terms of profitability, ecology, production and social and community well-being.
Change will be reported over time relative to a baseline state: ie before the establishment of a predator/ exclusion fence, during construction of the fence, and after the fence is closed.
“Preliminary investigations by the SFL scientific team have revealed remarkable changes in pasture growth, lambing percentages, increases in biodiversity and producer confidence on the six properties visited to date,” said Soils For Life chief of staff, Natalie Williams.
Producers and properties in Queensland have been selected along a north-south axis located between Longreach in the north and Morven in the south. The project spans around 550km. Properties are located in several widely recognised bio-regions including Mitchell Grass Downs, while the central and southern reaches include the Brigalow Belt South and Mulga Lands.
These producers and their properties have been selected because they already employ ‘best-practice’ regenerative landscape management. Each producer will assist Soils For Life with the collection of evidence over time of:
■ Production, financial and environmental performance information, verified by a combination of quantitative and qualitative observations
■ Wild dog, pig and fox control as well as control of total grazing pressure
■ Pasture resting / regenerative grazing, once they have established the predator/exclusion fence ■ Property records, historical events such as drought and observations of wildlife.
Landholders wanting to become involved can participate through the mentoring program and field days.
