The Exmoor Pony takes its name from Exmoor, a wild moorland area spanning parts of Devon and Somerset in southwest England where the breed has lived for centuries, possibly millennia. The name reflects the inseparable connection between these ponies and their native landscape, a relationship that shaped their unique characteristics through natural selection rather than human breeding decisions.
The Exmoor Pony Society, formed in 1921, maintains the breed registry and establishes standards that preserve the ancient type. All registered Exmoors must be inspected to verify conformity to breed standards before registration. This inspection process ensures that the primitive characteristics distinguishing Exmoors from other British native ponies are maintained across generations.
Two historical types are sometimes referenced: the Acland type and the Withypool type. The Acland type represents the foundation of today's registered population, descending from ponies preserved by Sir Thomas Acland when Exmoor's Royal Forest was sold in 1818. The Withypool type, slightly larger and darker with a straighter profile, developed in a different area of the moor. Modern registered Exmoors primarily represent the Acland type.
In North America, the American Exmoor Pony Registry maintains records for imported ponies and their descendants. The small North American population, established through 1950s imports to Canada and subsequent introduction to the United States, remains genetically connected to British foundation stock. Conservation efforts on both continents work to preserve this critically endangered breed.
