This year's top pick was the Waikēkēwai wetland reconstruction project in the Selwyn District of Canterbury.
WGA set up a hydrological monitoring programme with the help of the Te Taumutu Rūnanga, Environment Canterbury and Boffa Miskell. Monitoring the Papatahora Stream is a vital part of the project to ensure a smooth water redirection through the reconstructed wetland at the Te Taumutu marae.
Our team installed an external staff gauge (ESG) and piezometer to monitor water levels at the Papatahora Stream. Extracting a soil sample from the wetland adjacent to the stream allowed them to investigate the layers beneath, while Environment Canterbury's Rad Gulliver recorded flow rates across the Papatahora Stream.
This culturally significant wetland will improve the water quality of the Papatahora Stream and provide mahinga kai and biodiversity benefits to the Rūnanga. Understanding the streams' hydrology is essential to ensure the wetland functions properly to support plant and aquatic life.
Learning valuable Mātauranga Māori of the stream, together, we are building an important story of the Papatahora Stream through merging traditional knowledge and practices with modern-day science.
