The project, located at Wakehurst Place, in West Sussex, in the High Weald of southern England (grid reference TQ340315), is dedicated to enhancing the resilience and coherence of the UK's ecological networks by improving the quality, quantity, and diversity of UK seed species available for use in conservation, rehabilitation, and restoration projects.

Seed production is focused on species that are difficult to obtain on the commercial market, due to harvesting, germination, or processing difficulties.

Species are often regenerated to create a large collection of seeds of a particular UK provenance, such as the South Downs' Primula veris (cowslip), or from a particular environmental habitat.

[9] The site is also open to the public as part of a visit to Wakehurst, and provides a useful environment to observe and photograph plant pollinators.

Support covers the entire range of seed handling from harvesting, through processing, testing, and storage, to distribution, and sowing.

The UKNSH provides advice and services through consultancy to enable the continuation of the project beyond the four year funding of the Esmée Fairbairn Foundation.
