NZ wetlands sustain eel populations amid climate change, land‑use pressures, and Māori stewardship traditions

Recent trophic analyses demonstrate that wetlands supply up to 45 % of the protein intake for juvenile eels, linking primary productivity, macroinvertebrate abundance, and water quality. Climate‑model projections indicate that warming and altered precipitation will exacerbate nutrient loading, threatening these food webs unless mitigated. The research employs robust meta‑analysis and long‑term monitoring, providing a solid empirical foundation for policy.
The health of New Zealand's wetlands is inseparable from historic land‑use legacies, contemporary agricultural pressures, and the cultural stewardship of Māori iwi, whose kaitiakitanga offers a resilient template for ecosystem management.
Scientific evidence shows that eels rely on wetland food webs, yet policy continues to privilege carbon accounting and flood control without addressing nutrient runoff or the rights of marginalised communities. By weaving indigenous epistemologies, historical accountability, cross‑cultural reciprocity, and forward‑looking climate scenarios, a co‑governance model can restore wetland connectivity, secure eel populations, and deliver climate‑adaptation benefits. Such an approach demands legal recognition of Māori water rights, integrated catchment regulation, and educational initiatives that embed both scientific and artistic‑spiritual understandings of water as a living entity.
