Two stallions fight over mares in one of the two breeding herds on Karen Sussman’s wild horse preserve in Lantry, S.D. Sussman has rescued more than 300 wild mustangs who might otherwise have gone to the slaughterhouse. She cares for them through her organization, the International Society for the Protection of Mustangs and Burros, ISPMB. Melanie Stetson Freeman/Staff
Wild to mild: A mare nuzzles Ms. Sussman, who has names for all the 300-plus horses in her care. Although initially wild, many of her rescues are now people-friendly. Melanie Stetson Freeman/Staff
A colt stands near its mother in a grassy field on the plains. Sussman allows this herd to breed to increase its numbers. Melanie Stetson Freeman/Staff
Mane fashion: This mustang sports a multicolored mane that seems to part in the middle, another unusual trait. Most horses’ manes fall to one side. Melanie Stetson Freeman/Staff
Rescued wild horses trot across the plains at dawn. In 1900 there were 2 million of them. Some 34,000 wild horses (and 5,000 wild burros) still roam the plains. Periodically, some are rounded up to keep the population in check. Adoption is encouraged, but many are sold for slaughter. Sussman rescued this herd when there were only 31 of their kind left.

Icy Blue: Only one of Ms. Sussman’s four herds has horses with blue eyes, an unusual trait. DNA tests show that some mustangs descend from original Spanish stock. Thoroughbred and even draft-horse lineage are present in others. Melanie Stetson Freeman/Staff
Tele Tub, one of Sussman's 11 cats, follows her everywhere and loves to ride in the truck. Melanie Stetson Freeman/Staff
Sussman uses her tractor to bring hay to one herd. Last year she paid $250,000 just for hay. This year, because of drought, she expects the cost of hay to increase by at least 30 percent. Melanie Stetson Freeman/Staff
Lunch munch: Wild horses eat their hay in a smaller enclosure for older and injured mustangs. Sussman struggles to raise the funds to care for all her rescues, including veterinary bills and special feed. Melanie Stetson Freeman/Staff
Horses come say hello to Janell Davidson, Sussman's office assistant, who is driving one of the farm's trucks. Melanie Stetson Freeman/Staff
One of the horses Sussman got from a US Bureau of Land Management auction has an identifying brand on its neck. Horses are freeze branded, usually on the left side of their necks. Melanie Stetson Freeman/Staff
Roll play: Why do horses do this? To dry and refluff their coats, perhaps, or to get a dusty coating that keeps them cooler and repels insects. Or it may be just to get a good scratch. Melanie Stetson Freeman/Staff
Sussman gives instructions to Dave Shillingstad, one of two local men she hired to help her care for her mustangs and her farm. Melanie Stetson Freeman/Staff
Two wild horses nuzzle each other. Ranchers say mustangs are invasive, a nuisance. Activists defend them. Melanie Stetson Freeman/Staff
Stallion fights can be vicious, with biting and kicking. Most stallions carry battle scars. Melanie Stetson Freeman/Staff
