Oceania Brumby in Australia Kaimanawa horse in New Zealand Marquesas Islands horse on Ua Huka, Marquesas Islands, French Polynesia Semi-feral horses In the United Kingdom, herds of free-roaming ponies live in apparently wild conditions in various areas, notably Dartmoor, Exmoor, Cumbria (Fell Pony), and the New Forest. Similar horse and pony populations exist elsewhere on the European continent. These animals, however, are not truly feral, as all of them are privately owned, and roam out on the moors and forests under common grazing rights belonging to their owners. A proportion of them are halter-broken, and a smaller proportion broken to ride, but simply turned out for a while for any of a number of reasons (e.g., a break in training to allow them to grow on, a break from working to allow them to breed under natural conditions, or retirement). In other cases, the animals may be government-owned and closely managed on controlled reserves.
