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 five graduate students and three summer research 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.

Within the Cultural Keystones Species programme (CKS) new ways to communicate the state and trends of taonga populations have been designed to meet the needs of our partners and to deliver tools and knowledge that support the protection and restoration of freshwater taonga species.

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. The lining is held in place by weights (e.g., rocks or sandbags) or by pinning. This control method is also called ‘benthic barriers’.
