Nutrients, sediment, and microbial contaminants are mobilized from urban and agricultural landscapes and enter streams, rivers, lakes and estuaries.
NIWA has released two booklets to provide advice on the cultivation of native submerged macrophytes to help rehabilitation initiatives in freshwater and saltwater environments.
More than 300 secondary school students enjoyed a brief stint as freshwater researchers to help rid the country of invasive freshwater aquatic species.
NIWA has updated training materials and restarted a course that explains the use of a riparian planning tool to achieve a range of water quality and environmental outcomes.
The finishing touches have just been made on a NIWA-led project which aims to prove the performance of constructed wetlands on New Zealand farms.
Alligator weed was introduced to Northland, New Zealand in the 1880s-1900s, and is now well established in the region and further south to the Waikato.
New Zealand’s population is increasingly urban. As of 2018, major urban areas in Aotearoa accounted for more than half of the population. As the population grows and urban development expands and intensifies, freshwater environments in urban areas are coming under increasing pressure.
A new programme at NIWA will focus on finding ways to protect our freshwater species now and in the future.
