To safeguard Aotearoa’s unique wētā by engaging, empowering, and educating communities to help preserve their species diversity and restore their habitats
Our mission
The Wētā Conservation Charitable Trust aims to preserve New Zealand’s biodiversity so that wētā, grasshoppers and allied insects (Orthoptera) and their natural habitat are protected to benefit present and future New Zealanders.
The most recent assessment of the threat classification status of New Zealand Orthoptera (2022) recognizes 162 taxa, not all of which have been described; 157 of these are native. Of 157 taxa, 18 are listed as “Threatened”, 27 are “At Risk”, 17 are “Data Deficient”. The main threat to all of our endangered Orthoptera is predation by introduced mammals, followed by habitat loss.
