Ngā rākau taketake – combatting kauri dieback and myrtle rust

The New Zealand’s Biological Heritage National Science Challenge Ngā koiora tuku iho has received a three-year SSIF investment of $13.75 million for research to address kauri dieback and myrtle rust. A science platform is a combination of people, facilities, information and knowledge that provides a particular, ongoing science and innovation capability for New Zealand.

Description

Key areas of strategic focus for the investment will align with priorities identified by the kauri dieback and myrtle rust Strategic Science Advisory Groups and will include:

• Validation of a suite of tools to efficiently and accurately map the spread of KDB and MR – research with potential for immediate benefits for management of these diseases;
• Empowerment of communities/stakeholders to map and monitor the distribution of the two diseases and their impacts;
• Generation of new knowledge to establish areas of longer-term strategic science leading to development of novel management tools and solutions; and
• Development of new understanding of the human dimensions of forest health management, recognising that social-ecological ‘systems’ research is crucial to achieving greater impact in the long term.

Ngā Rākau Taketake – Saving Our Iconic Trees – is a three-year strategic research investment finding new solutions for management of kauri dieback (KDB) and myrtle rust (MR). The programme was developed jointly by researchers, stakeholders, agencies and communities and is administered by New Zealand’s Biological Heritage National Science Challenge - Ngā koiora tuku iho.

Funding is allocated across seven themes aligning with priorities and recommendations of MR and KDB SSAGs. Themes redress historic under-funding in areas essential to deliver solutions: 

• Oranga: Māori-centred research, kaupapa Māori and research involving Māori; application of Mātauranga-derived solutions; 
• Mobilising for Action: Social science developing new communication tools and messages and understanding values driving sustained community action; 
• Risk assessment and ecosystem impacts:  Holistic risk assessment framework to guide management and restoration;
• Conservation and Restoration – supporting mana whenua-led restoration of at-risk species, and identifying optimal locations to protect and restore taonga plants.

Knowledge gaps around biology and spread of pathogens are addressed in Host, Pathogen & Environment; a novel Mātauranga Māori-based surveillance framework has been designed in Integrated Surveillance; and tools for detection and disinfection are under rapid development in Control, Protect, Cure. Field monitoring of susceptibility of at-risk myrtle species is done in collaboration with researchers from MBIE programme Beyond Myrtle Rust. Teams work collaboratively with DOC to deliver practical solutions including tikanga-based approaches to seed collection and storage.

Research teams, each with a Māori co-lead, include experienced and emerging researchers from a range of organisations and span a diversity of specialists not previously engaged in the fight against KDB and MR: psychologists, anthropologists, socio-economists, artists, and engineers. Research projects are co-designed with mana whenua and agencies including DOC, MPI and Regional Councils to facilitate research uptake and impact.

In November 2018, the Government allocated ‘surge’ investment of $8.75 million for kauri dieback (KDB) and $5M for myrtle rust (MR) research over three years. The investment is being administered through the New Zealand’s Biological Heritage National Science Challenge, Ngā koiora tuku iho, as a SSIF Platform.  The new programme is titled Ngā Rākau Taketake which talks to the historical connections Māori, and New Zealanders, have with our kauri and myrtaceae trees. “Taketake” talks to the permanence of that relationship. This platform aims to protect and restore that relationship and connection.

The BioHeritage Challenge immediately established a working group to increase our understanding of the highly fragmented research landscape, engage with stakeholders most impacted by KDB and MR, and identify areas needing urgent investment. This work built on from and extended previous “research stocktakes” undertaken by the BioHeritage Challenge and MPI.  A ‘Scoping Group’ was also established to focus on longer-term investment needs and identify research gaps requiring longer-term investment, in alignment with science plans developed by the KDB and MR Strategic Science Advisory Groups (SSAGs).  Working groups included representatives from the KDB/MR SSAGs, KDB Tangata Whenua Roopu, iwi representatives and researchers from a range of disciplines from Universities and CRIs. 

The Scoping Group has identified two areas for early investment: development of a mātauranga Māori-based surveillance framework; and incorporation of mātauranga Māori (Māori knowledge) into the protection of both kauri and myrtaceae trees, while increasing the holistic resilience of the forest ecosystem. These research areas were also recognised as a high priority by the Strategic Science Advisory Groups for myrtle rust and kauri dieback.
