Braided Rivers 2021 Seminar Advances & Emerging Issues in Managing Braided Rivers

Braided Rivers 2021 Seminar Advances and Emerging Issues in Managing Braided Rivers

This event has now ended. See this page for all of the presentations.


Thanks to funding from:

This is a FREE event.  Morning & afternoon teas (with yummy cheeses from Karikaas) and lunch are included.


This seminar carries on from historic workshops held at Environment Canterbury to update managers and researchers on black-fronted tern research and management, and a TAG (Technical Advisory Group) workshop with a wider focus on braided river birds. A subsequent workshop, hosted by the Ashley Rakahuri Rivercare Group, resulted in the creation of BRaid in 2006. In the last few years, these events have grown in popularity, attracting a more diverse audience. However, the aim remains the same: to freely and openly share information and research and create a networking opportunity for those working to protect and restore these globally rare ecosystems and the endemic taonga species that inhabit them.
