Pastoral habitats in the County of Devon in southwest England range from lowland temporary pastures to upland rough grazing. These habitats have resulted in the development of locally adapted livestock types. In 2010, Devon is repository to two cattle, five sheep and two equine breeds: Historically there were sheep, equine and pig breeds now extinct or subsumed into existing types. Breed origins are discussed and physical descriptions and main production characteristics are provided. Information is given on organizations in England and overseas that promote the breeds and are responsible for maintaining pedigree records. Available numerical data are presented and conservation status discussed. All sheep and equine breeds are at risk because of low numbers or restricted geographical distribution. The government provides no direct assistance for conservation or preservation although there is limited support for native breeds from agrienvironmental schemes. Owner awareness of breed values, “designer” made for thriftiness under harsh conditions, supported by civil society organizations, will render them “fit for purpose” for new uses in conservation grazing in environmentally sensitive areas, maintenance of plant diversity and sustainable production, and assist in ensuring survival of these invaluable genetic resources.
