The island was purchased in 1870 by John Dooly Sr., and he established the Island Improvement Company, which managed the island and ranches from 1884 until 1981. The State of Utah purchased the northern part of the island in 1969, and acquired the remainder in 1981 when the state purchased the historical Fielding Garr Ranch. Subsequently, the cattle and sheep were removed. Antelope Island State Park was established in 1981 as part of the Utah State Parks System. The island is accessible via a 7-mile

. Later the focus turned to making the island a state park. The first successful bid towards the creation of a state park took place in 1969 when on the northern end of the island were acquired by the State of Utah. The final purchase of the Fielding Garr Ranch in 1981 led to the entirety of Antelope Island being given protected status as Antelope Island State Park. A. H. Leonard purchased the herd of bison from the Dooly family in 1926. Leonard intended to sell the herd to zoos. He found it impossible to get the bison off the island due to the water level and the drafts and sizes of the boats that were available to him. At this point he offered to sell the herd to the federal government if a national park were to be established on the island. ''

of Utah asked the National Park Service consider the Great Salt Lake for inclusion in the National Park System in 1959. The study had high praise for Antelope Island as a potential national park, but found "little else worthwhile about the Great Salt Lake". The National Park Service was concerned with a lack of planning by the State of Utah and the fact that the lake was used as a dumping site for municipal and industrial waste. The Park Service was impressed by the scenic and recreational possibilities of the northern end of Antelope Island, describing it as the "most impressive site of the lake." The qualities of the island were not enough to persuade the park service to seek the creation of a national park encompassing the Great Salt Lake. The park service cited years of "mismanagement, apathy, and lack of any coordinated plan for its proper development."

Activities

Antelope Island State Park is open for year-round recreation. It features a marina, beach, campground and hiking trails. Tourists pay a fee to access the park via the islands causeways. The northern are developed. There are several campsites, a day use area, swimming area, and picnic areas near Bridger Bay on the northwestern end of the island. There is a restaurant on Buffalo Point. The rest of the park is largely undeveloped. A few old roads cross the island and so do some hiking trails. The remnants of old mining claims and the Fielding Garr Ranch are open to park visitors. There are plans to construct a historic boat display at the marina. Antelope Island is known for its scenic beauty, especially in the northwest quadrant of the island at Buffalo Point and White Rock Bay, where mountains and hills overlook beaches as well as the reflecting waters of the Great Salt Lake and other islands that are visible in the lake.

Bison

John Dooly, owner of the island in 1893, with the help of William Glassman brought a herd of twelve bison to Antelope Island.

. The bison were an important resource for the native tribes of the western United States. The United States government knew this and began a campaign to rid the plains of the bison, thereby depriving the Native Americans of their most prized natural resource and making them dependent on handouts from the government. Without the bison the Native Americans were forced to "seek peace". Some conservationists saw that destroying the bison population was detrimental to the future of the nation and in 1874 Congress voted to stop the government sponsored slaughter. By the 1890s approximately 800 bison remained. Dooly purchased the bison after Glassman had failed to establish a bison preserve on the south shore of the Great Salt Lake. Glassman had hope to attract tourists to the area with some of the few remaining bison in the United States at the time. His venture failed and he was forced to sell some of the herd at

, the bison thrived on the island and the herd rapidly increased in size. The island was opened for bison hunts beginning in 1896. The hunting of bison on the island was limited to those who could afford the $200 requested by Dooly and his ancestors. Heavyweight boxing champion Jack Dempsey and 1920s sports writer Robert Edgren were just two of the celebrities that came to the island to shoot a bison. Bison hunting continued on the island until 1926 when the final "Big Buffalo Hunt" eliminated all but a few of the bison. Public sentiment changed during the 1920s and activists began to call for the protection of the herd on Antelope Island. A

, '' The Covered Wagon'' (1923), was partly filmed on Antelope Island when buffalo hunt and buffalo stampede scenes were needed. At the time, the bison herd on Antelope Island was possibly the largest herd of bison in the United States. After much effort, about 350 of the animals were herded into a stampede, which was then filmed under the direction of James Cruze. The movie is considered by some people to be the first great Western epic and it established some of the tropes that persist in Western movies, such as circling the wagons in time of danger or attacks. During filming of the movie, seven buffalo were shot and killed for the hunting scenes. "Don't grow sentimental over the seven", said Cruze, the director of the film. "The folks out there would like to get rid of the whole herd and they would, but for the sentimental hubbub that is always raised when they talk of rounding out the buffalo. The animals are worthless — there isn't worse meat on Earth to eat — and they ruin the whole territory for cattle grazing purposes. So the buffalo remain — sentimental reminders of the America of the past." The hunt of 1926 was covered by ''

. The Antelope Island bison herd and the island remained in private hands until 1969 when the northern of the island were purchased by the state of Utah. The southern end of the island was acquired in 1981, granting the entire herd protected status on Antelope Island State Park. In 1986, park rangers saw the need to begin controlling the bison population to prevent overgrazing and disease. The first roundup was held in 1987 and it has since become an annual event that brings in revenue by way of the sale of excess bison and tourist dollars brought in by spectators. Every year, in late October, all the bison on the island are herded to a central area in a "Great Buffalo Roundup" and sent briefly into pens where they are examined, weighed and vaccinated, whereupon decisions are made on culling and selecting breeding stock. The majority of the bison are then released within a few days, and are again allowed to roam free on the island. The Antelope Island bison herd fluctuates in size between 550 and 700 head, and is one of the largest publicly owned bison herds in the nation. The reason for the variability of the size of the herd is that the bison produce approximately 150 to 200 calves annually, and since this is prime prairie habitat for bison, with no significant predators, the herd can increase by up to half every year. It has been determined that 700 head is near the maximum preferred carrying capacity for bison on the island, so the excess bison need to be culled. Bison from this island are often sent to other herd locations around North America due to their genetic isolation, some unique genetic markers contained in the population, and because of their disease-free condition. Some bison are also purchased at the pen site in a yearly public auction, and are taken as meat or breeding stock for commercial farms in other parts of the world. In 2020, the podcast '' This is Love'' released an episode featuring Antelope Island and two bison attacks that took place there.

. Biologists at the park and with the state of Utah felt that Antelope Island would be an "ideal oasis" for establishing a "nursery herd" of bighorn. The sheep are protected from human threats on the island and can be used to reintroduce the bighorn in areas throughout western North America. The target population for the herd on the island is about 125–150 head. When the numbers are greater than 150 the excess sheep are gathered and sent to new homes. The nursery herd has largely been a success. The herd is thriving and it is providing the needed animals to re-establish or strengthen herds of bighorn sheep elsewhere. There are some problems.

s on the island and the sheep that grow up on Antelope Island grow up without an "innate fear" of their primary predators on the lands away from the island. Another problem with moving the sheep is the financial cost of moving them off the island. It can cost up to $1,000 per animal. The sheep are moved by helicopter from the island and then by truck to their final destination. Also the sheep undergo a tremendous amount of stress with the move and biologists liken moving an animal from one place to another with transplanting organs in humans. The bighorn are placed on public and private lands with the help of the Foundation for North American Wild Sheep. The foundation buys grazing permits from domestic sheep ranchers. In exchange for the grazing rights the ranchers agree to remove their domestic herds. In 2018 a mysterious respiratory ailment felled most of the island's sheep. The remaining sheep were shot in 2019 in order to prepare the island for repopulation. On January 29, 2020, 25 bighorn sheep were relocated from from Montana’s
