Rnz: Our Changing World

PhD student Kiamaia Ellis describes crayfish as a vulnerable taonga species. Local iwi in Tauranga believe the crayfish population is decreasing because of urban, industrial and harvesting pressures. But Kiamaia is keen to be a part of the solution, so she's studying the resilience of pēpi kōura / baby crayfish. She wants to understand how these tiny species that take eight years to become an adult are able to thrive based on a kaitiakitanga or guardianship approach.
