Threatened Plant Breeders Network

We are aiming to establish a permanent group of experts who can grow a range of endangered plants and are currently looking for volunteer conservation groups to join the Threatened Plant Breeders Network.

We need groups who can, initially, grow the endangered herbs Lepidium banksii (coastal peppercress) and Leptinella filiformis (slender button daisy).

It’s intended that the group will first trial the coordinated cultivation of these two herbs, and then become a permanent group growing a range of endangered plants. The trial is a component of a strategy for the ex-situ management of New Zealand plants, being developed by the Department of Conservation and the Botanic Gardens of Australia and New Zealand. This work has been undertaken with the support of Stout Trust.
