The GB Red List for Vascular Plants report provides a comprehensive revision of the previous list, published 20 years ago.

The term “vascular plants” covers all seed-bearing plants (flowering plants as well as conifers) and pteridophytes (ferns and fern allies).

Red Lists are created using internationally recognised criteria to assess threat status, and are crucial in providing the evidence that underpins nature conservation, helping prioritise future action.

The decline of these plants is not only a loss for wildlife but a warning sign for us all, said Herts and Middlesex Wildlife Trust.

Many play key roles in supporting pollinators, maintaining healthy soils, and regulating water, all of which people rely on for food, clean air and resilience to climate change.
