The Rare Breeds Survival Trust

The Watchlist contains all native breeds of cattle, goats, horses, pigs, poultry and sheep. Conservation criteria determine into which category breeds are listed.

What is a breed

A breed is defined as a group of animals that has been selected by humans to possess a set of inherited characteristics that distinguishes it from other animals within the same species.

For recognition by the Trust a breed must be an original breed, or a native breed of which at least one parent breed is believed to be extinct. Evidence of its continuous documented existence will take the form of written material e.g. newspapers of the time, or historical writings.

An original population is that segment of an original breed, or a native breed of which at least one parent breed is believed to be extinct, which has not suffered unacceptable introgression.

Any breed wishing to be accepted onto the Watchlist should submit a minimum of 25 years (preceding application) of continuous verifiable pedigree data in the form of annual registrations. If electronic records exist, these should be supplied in full. Any supplementary information will be discussed with the Breed Society before use. In addition, all breed analyses will be released only to the Breed Society in the first instance - all subsequent releases must come with Breed Society approval. A breed whose numbers of registered breeding females are estimated by the Trust to be below the Category 6, "Other Native Breeds", threshold will be accepted into the appropriate Watchlist category.

Footnotes

Placement of a breed within Watchlist categories may not be wholly defined by registered breeding female population size (the numeric thresholds serve as a guideline). Population genetic factors and current trends in breed density and distribution are also included in making assessments of endangerment.
If insufficient information exists to fulfil all current guidelines, the RBST may occasionally otherwise recognise breeds it considers to be of genetic conservation importance.
In addition to the registered flocks of Boreray and Soay sheep, feral populations exist in the western isles of Scotland.
The following breeds of Irish Origin can be found in the UK and historically have been a part of British agriculture: Kerry and Dexter cattle, Galway sheep and the Irish Draught horse.
