Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Corokia collenettei faces significant pressure from habitat degradation and fragmentation across its limited range in New Zealand's coastal and lowland areas. Invasive plant species compete directly with this endemic shrub for resources and space, while browsing by introduced mammals damages regenerating populations. Urban development and agricultural expansion continue to reduce available habitat, particularly affecting the species' ability to establish new populations in suitable coastal scrubland environments.
