VSTWP Extension Officers

The VSTWP contracts three Extension Officers to develop and implement community-led targeted extension projects in the regions around the containment line, and within the core infestation area. All of the extension officers have a strong background in agricultural science and invasive plants, as well as previous experience in serrated tussock management.

Please find a biography on each of our three extension officers below, with a fourth extension officer likely to be contracted in the coming months.
