About the Watchlist

The RBST Watchlist is a document showing the rarity of the UK's native breeds of mammal. 

Every year, RBST collects data from over 130 breed societies, including the number of males and females registered. This data is used, along with a multiplier, to estimate the number of registered breeding females in the UK for each breed. This is used to place each breed either in one of the 5 categories on the Watchlist, or in the 'Other Native Breeds' category, for those that are not rare but still fulfill our criteria for a native breed.

 Notes
  • 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 (such as inbreeding and genetic erosion) and current trends in breed density and distribution (geographical concentration in a small area) can mean a breed will be highly vulnerable to disease outbreaks, and so are also included in making assessments of endangerment.
  • If insufficient information exists to fulfill 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 and Connemara pony.
Native Breed Criteria

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.
