Seven new “saltwater wedges” have been mapped in the Ūawa catchment in an effort to understand inanga (whitebait) distribution.
A saltwater wedge is the furthest point inland that saltwater reaches on a spring high tide.
In February and March this year, Gisborne District Council’s environmental science team collaborated with landowners and whānau of Te Aitanga a Hauiti iwi with Davina Walker, Andrew Walker, Chris Marsh, through Taniwha Connections’s Mere Tamanui, to map these saltwater wedges.
Taniwha Connections is an initiative Mere Tamanui, from Ūawa, created to engage whānau ki te whenua through environmental connections.
Inanga - the most common of the five whitebait species - spawn (lay their eggs) near the saltwater wedge during late summer and autumn.
