- Summary
- Background Christchurch City Council (CCC) has recently conducted a riparian management trial involving cessation of riverbank vegetation clearance in Christchurch City waterways. This report presents results from a survey of īnanga (Galaxias maculatus) spawning habitat completed in April 2017. The primary purpose was to assess the effectiveness of the CCC vegetation management trial for improving īnanga spawning habitat. While the trial has wider objectives around improved environmental outcomes, īnanga spawning habitat is directly affected by bank cutting and other forms of vegetation clearance. It is an excellent performance indicator for waterway management as well as being a specific management objective.
