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

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

Thanks to funding from:

Rakaia Catchment Environmental Enhancement Society

Cynthia and Gerald Ward Charitable Trust

  Environment Canterbury biodiversity funding

This is a FREE event.  Morning & afternoon teas 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.
