Hayley relishes the challenge of feed base improvement in tropical livestock production systems. As a Pasture Scientist, her research interests range from the systems level of ruminant livestock production down to plant cellular processes. Hayley completed her PhD at the University of Queensland studying the effects of root-zone salinity on plant production and water use of tropical and subtropical pasture species. With strong industry ties, and hands-on experience in intensive, extensive and smallholder grazing systems, Hayley is determined to deliver profitable and sustainable solutions to livestock producers of northern Australia and the Asia Pacific Region.

Research Interests

  • The Sterile leucaena project
    Developing breeding and commercialisation strategies to accelerate the availability of sterile leucaena for adoption across the northern beef industry, particularly Western Australian bioregions.
  • Rangeland weed management
    Advance splatter gun technology (low-volume high-concentration herbicide application) for high priority rangeland weeds in northern Australia.
  • Transforming growth pathways with leucaena
    Evaluation of the effect of native trees and low soil sulphur status on the productivity of leucaena grown in lightly timbered basaltic woodlands otherwise constrained by vegetation management legislation.
