Introduction by Kura, Marine Science Professor at the University of Waikato
Presentation begins with a personal connection to the audience and a brief introduction of her origins and cultural background.
Mātauranga Māori and Marine Science
Focus on integrating Māori knowledge with scientific research.
Key concepts defined:
Mana: The prestige or authority behind a person or group.
Tapu and Noa:
Tapu: Sacred, often related to environmental restrictions (e.g., pollution).
Noa: Common, referring to a state where restrictions no longer apply.
Mauri: The life force central to living beings.
Research focus: Ohiwa Harbour
Description of Ohiwa Harbour, its history, and tribal significance.
Historical context:
Originally a food basket with rich mussel populations.
Decline in green-lipped mussel populations due to various factors (e.g., sedimentation after flooding, overharvesting).
Use of traditional knowledge to investigate the decline:
Engaging elders to gather multi-generational insights on mussel habitats.
Initial Research Questions
Restoring mussel populations through sustainable methods:
Can mussel recruitment be supported?
Can traditional genetic lines be maintained?
Could biodiversity be enhanced through restoration activities?
Restoration Efforts
Implementation of restoration stations to facilitate mussel growth.
Traditional materials (biodegradable) used for mussel farms, experimenting with various plant materials and their effectiveness.
Significant types used included: Flax, cabbage tree leaves impacting environmental improvements and sustainability.
Impact of Plastic Pollution
Overview of prevalent issues:
Substantial amounts of plastic pollution affecting marine life and ecosystems.
Mussels as filter feeders accumulating microplastics posing food chain risks.
Outcomes and Findings
Introduction of biodegradable mussel lines resulted in successful spat attachment, leading to increased mussel populations.
Significant findings included:
57 times more biodiversity on biodegradable lines than traditional plastic lines.
From under 80,000 mussels in 2019 to nearly 800,000 by 2021 following restoration initiatives.
Notably, management of predator species (sea stars) was essential for supporting mussel recoveries.
Biodiversity Considerations
Management of balance between mussels and their natural predators, ensuring ecosystem health.
Engagement with the community and youth for ecological awareness and future conservation efforts.
Future Directions and Applications
Exploration of potential product development from sea stars (e.g., hand creams) for funding and sustainable management of the harbour's ecosystems.
Long-term goals aimed at preserving marine biodiversity and educating future generations on sustainable practices.
Closing Discussion
Encouragement of engagement from participants in discussions about the questions raised during the presentation.
Additional cultural considerations and the importance of incorporating Māori perspectives into environmental science are highlighted.
Conclusion
Emphasis on safeguarding marine environments for future generations, highlighting the interconnectedness of knowledge diversity and ecological health.
