An opinion editorial by NIWA Chief Scientist of Freshwater and Estuaries, Scott Larned.
The quality of New Zealand’s waterways features prominently in a newly released report on the state of our environment.
The report, Environment Aotearoa 2019 (EA2019), was prepared by the Ministry for the Environment and Statistics New Zealand as required by the Environmental Reporting Act. EA2019 uses investigations from five environmental domains (land, freshwater, marine, climate and air) to report on priority issues.
Doctoral student, Michele Melchior, has made an important breakthrough in the effort to save New Zealand's freshwater mussels, or kākahi.
Kākahi were once a valuable food source for Māori, and they also play a crucial role as indicators of the health of waterways. All three kakahi species in New Zealand are in decline.
NIWA is working with DairyNZ, Regional Councils and farmers on a new project to evaluate riparian planting options that have economic as well as environmental benefits. The project is co-funded by the Sustainable Farming Fund. Read the article Research into productive riparian buffers on the DairyNZ website, or contact Dr Fleur Matheson.
Water New Zealand has recently published an update and expansion of the old Ministry of Works Guidelines for Oxidation Ponds 1974.
