Devon’s Unique Landscape, Spanning Rugged Uplands, Coastal Clifftops, Lowland Heath, And Recovering Industrial Sites, Relies Heavily On Hardy Native Pony Breeds As Ecological Keystones.
Primarily utilising Dartmoor and Exmoor ponies, conservation grazing in the county leverages specific biological traits to maintain biodiversity, manage scrub, and preserve diverse vegetation structures without the need for heavy machinery or synthetic inputs.
Ecological Mechanics and Grazing Dynamics
Ponies function effectively as landscape managers because their physiological adaptations and feeding behaviours differ significantly from those of other livestock, such as sheep and cattle. Equipped with both upper and lower incisors alongside powerful molars, ponies can crop vegetation close to the ground and grind down tough, fibrous material.
Unlike sheep, which selectively target the most nutrient-dense and palatable shoots, ponies readily consume coarse vegetation. This includes mature gorse, bracken stems, and invasive purple moor-grass, particularly during periods of scarcer winter and early spring forage. By suppressing dominant grasses and aggressive scrub, grazing ponies generate a complex mosaic of short swards, tussocks, and patches of bare earth. This structural diversity provides essential habitats for ground-nesting birds, reptiles, amphibians, and invertebrates. Furthermore, the physical movement and weight of ponies create minor soil disturbances, breaking up dense turf thatch and heavy soil compaction. This process assists with seed dispersal, aids germination, and establishes micro-sites for plant colonisation.
Examples of Conservation Grazing Across Devon
Dartmoor National Park, including sites like Bellever, features free-roaming semi-wild hill ponies alongside structured herds managed in collaboration with organisations such as the Dartmoor Pony Heritage Trust. These ponies have grazed Dartmoor’s open moorland for centuries, suppressing invasive moor-grass tussocks and encouraging heather regeneration to establish a resilient habitat matrix for upland fauna and flora.
North Devon National Trust sites, such as Woolacombe, utilise managed groups of Exmoor ponies through partnerships with organisations like the Moorland Mousie Trust. Operating within coastal and clifftop environments, their grazing and browsing actions control aggressive coastal scrub, preventing coarse vegetation from smothering fragile maritime grasslands and specialised coastal flora.
Devon Wildlife Trust reserves implement controlled, rotational grazing schemes utilising hardy native breeds across diverse reserve typologies. At Bystock Pools, Exmoor and native ponies manage lowland heath boundaries, browsing down invasive birch and pine saplings to preserve open heathland. At Andrew’s Wood, targeted pony grazing keeps dominant scrub encroachment in check. At Meeth Quarry, grazing helps maintain a varied sward structure across the recovering mosaic of grassland, wetland margins, and developing scrub habitats, preventing monocultures from establishing on recovering substrates.
Private and local wildlife projects, such as the Rowden Wildlife Project, deploy pedigree Dartmoor and native ponies to manage enclosed local nature reserves. Their prehensile upper lips and robust digestive systems allow them to browse wood-pasture margins and rough pastures, naturally sustaining balanced local ecosystems.

Infographic
Horses were the prime power source on farms in the past, and with the Bayeux Tapestry being on display in England at the time of producing this infographic I decided to use that as my style in producing this explanatory infographic.
