Iwi and community groups are at the forefront of river restoration, driving planting and bank restoration initiatives. These efforts are important and can yield significant water quality improvements, however, many aquatic species also suffer from poor structural habitat beneath the water surface. By targeting in-stream habitat (which is often neglected), we hope to facilitate significant improvements in ecological health. This project brings together science, kaupapa Māori, and collective enthusiasm for the rivers of Aotearoa New Zealand to advance restoration practice, using proactive habitat additions which anyone can help build. In-stream habitat structures focussed on fish and invertebrate refuge were collaboratively designed and trialled in Canterbury, New Zealand by Te Taumutu Rūnanga and the Waterways Centre. Inspired by flax wahakura (baby bassinettes), these habitat structures aim to enhance our freshwater taonga (treasured) species, boosting diversity and nurturing mauri (the life force of the river). Importantly, they also provide a storytelling opportunity and analogy in the protection of both babies and young fish, which is an effective tool to inspire and engage. Weaving and restoration wānanga were held at Te Pa o Moki Marae, close to Waikēkēwai Stream. These meetings brought the community together to create and deploy habitat structures, and also facilitated storytelling and sharing of Mātauranga Māori. Ongoing monitoring includes both ecological and cultural assessments, supporting the holistic nature of this project. This collaborative approach holds great promise for ecological health outcomes, and subsequent restoration of mauri will benefit all who interact with the water. Through sharing of knowledge, skills and Mātauranga Māori, we hope to kickstart ongoing, holistic restoration initiatives for years to come, and inspire kaitiakitanga (guardianship) in future generations.
