Funding source: Auckland Council and the University of Auckland Foundation.

This project aims to improve our understanding of how best to use phosphite in the treatment of kauri dieback disease using cutting-edge approaches.

Project description

Kauri dieback disease is a significant conservation threat to iconic kauri (Agathis australis) trees. Infection with the soil-borne pathogen, Phytopthora agathidicida, causes root degradation, basal trunk lesions, canopy dieback and eventual tree death. While there is no current cure for kauri dieback, there have been promising results with phosphite treatment improving tree health and longevity. However, more research is needed to determine how best to use phosphite to manage tree health. Relevant questions include:

  1. How often should trees be treated with phosphite? 
  2. What is the long-term physiological impact of phosphite treatment? 
  3. How can phosphite be used at the landscape-scale to protect forest health?

The successful applicant will work with the project team (including Auckland Council, Bioeconomy Science Institute, mana whenua, University of Auckland and international collaborators) to develop specific research questions that match their interests and expertise and the aims of the project partners. A range of resources, including access to existing datasets from the Waitakere Ranges, will be available. We are particularly interested in exploring the fate of phosphite within kauri plants using Stimulated Ramen Microspectroscopy in collaboration with the University of Nottingham.

This is an exciting opportunity to make a difference for conservation of the iconic ngahere (forests) of Aotearoa.

Desired skills

Applicants should have an undergraduate degree in Ecology, Environmental Science or a related discipline with an appropriate postgraduate qualification that includes research experience (Honours, Masters or equivalent).

Students should have an interest in one or more of the following fields: plant physiology, plant ecology, conservation, Mātauranga Māori and/or microbiology.

Preference will be given to students with strong data management and analysis experience, competency in the field and/or relevant laboratory skills.

We welcome applications from Māori and Pacific candidates.
