The Rare Breeds Survival Trust is a conservation charity[2] whose purpose is to secure the continued existence and viability of the native farm animal genetic resources (FAnGR) of the United Kingdom.

[4] Projects have included the collection of genetic material to ensure the future of rare breeds in a farm animal "gene bank".

This project received publicity in the wake of the foot-and-mouth disease crisis in the UK and was supported by Charles III (while he was the Prince of Wales).

[5] The Trust also supports the Manx Ark Project, which provides sanctuary for rare breeds at several sites in the Isle of Man.

[6] RBST publishes a watch list of rare and native United Kingdom breeds of domestic cattle, sheep, pigs, horses, goats and poultry.
