Why is native vegetation important?
Native vegetation is crucial for the health of New South Wales’ environment supporting agricultural productivity as well as the biodiversity that is central to Australia's cultural identity. Native vegetation:
controls erosion through protecting soils and riverbanks
reduces land degradation and salinity
improves water quality and availability
provides habitat for a wealth of unique biodiversity including threatened species.
In addition, native vegetation in NSW stores a significant amount of carbon, mitigating the effects of climate change.
There is an growing body of evidence related to the benefits of native vegetation to both on-farm production and broader catchment values.1
Healthy catchments and farming land can be estimated to increase farm productivity nationally by over $1 billion per annum (2002). This is a 5% increase in the total value of agricultural production.2
Benefits to farmers' bottom line
Farms with good native vegetation can improve economic outcomes for farmers by improving land value3, 4 increasing production outcomes, and reducing operating costs.
Increased production outcomes include:
increased crop yields6
improved pasture growth8
health benefits to stock include increases in stock weight and fertility and reduced stress and mortality6
Reduced operating costs include:
pollination of crops13
maintaining more water in the landscape reducing need for irrigation7
reduction of pests requiring less inputs or management actions5
Restoring Native Vegetation
The restoration of native vegetation, in combination with the protection and rehabilitation of remnant vegetation, can reverse the negative effects of clearing and habitat fragmentation.
Farmers may be able to secure financial assistance and can get advice from their local land service on revegetating their land.
