Freshwater

A four-year research programme focused on the co-management and restoration of our freshwater taonga species.

In collaboration with the University of Waikato, the CKS team has also supported students and scholarship interns through a variety of practical experiences.

NIWA is asking people in flood-affected areas to contribute photos to a national database to support understanding of flood hazard and flood risk.

This programme developed approaches to enable the recognition and prioritisation of cultural keystone species (CKS) in co-management, restoration and monitoring to help sustain the social, economic and ecological health and wellbeing of Aotearoa-New Zealand’s freshwater ecosystems.

New ways to communicate the state and trends of taonga populations.

Protection of the Awa Models enable us to predict how different uses of the land and water will impact river and stream health.

NIWA is developing a national river flow forecasting tool for New Zealand that aims to support and strengthen our planning for and response to extreme rainfall events.

Bottom lining is the installation of a flexible covering over the top of beds of aquatic weeds, similar to using weed matting in home gardens. This control method is also called ‘benthic barriers’.

The project aim was to harness the filter-feeding capacity of native freshwater mussels on rafts to assist in lake restoration.

Irrigation Insight is a joint industry programme funded by MBIE to examine, on working farms, the ease and effectiveness of using high-resolution weather forecasting, production potential, and drainage estimations for on-farm water management.

The Inner Hauraki Gulf/Tīkapa Moana ecosystem is facing proliferations of algae, de-oxygenation, reduced pH (acidification), reduced water clarity, and muddier sediments arising from historical and future land-derived contaminant inputs.
