Elk Island National Park (French: parc national Elk Island), is one of 43 national parks and park reserves administered by the Parks Canada Agency. This “island of conservation” is located 35 km east of Edmonton, Alberta along the Yellowhead Highway, which nearly bisects the park. It is Canada's 8th smallest in area, but largest fully enclosed national park, with an area of 194 km². The park is representative of the northern prairies plateau ecosystem and as such, the knob and kettle landscape is a mix of native fescue grassland, aspen parkland and boreal forest. As well, Elk Island plays host to both the largest and the smallest terrestrial mammals in North America, the wood bison and pygmy shrew respectively.

Elk Island is home to the densest population of ungulates (hoofed mammals) in Canada. A variety of wildlife, including plains bison, wood bison, elk, moose, white-tailed deer, mule deer, coyotes, and beavers are year round residents, as well as over 250 bird species that can be found in the park at various times of year. Most notable among these are the Red-necked Grebe, American White Pelican, Double-crested Cormorant, Great Blue Heron, Red Tailed Hawk, American Bittern and the Trumpeter Swan.

Wildlife management - True to its roots, Elk Island National Park still maintains a thriving elk population, estimated at 605 in 2007, as well as around 300 moose and over 500 deer. Reintroduction of traditional species has been an important focus as well. Besides the success of the wood and plains bison introduction, beaver were reintroduced in 1942, and in 2007 numbered near 1000. 1987 saw the beginning of a Trumpeter Swan reintroduction programme which is now seeing mating pairs returning to Elk Island, raising hope for a sustainable population.

Elk Island National Park also remains a seed herd for repopulation efforts in other areas. Elk Island elk have been relocated to various parts North America, including Ontario and the foothills of the Rockies. Plains bison have been reintroduced to conservation areas scattered throughout their historic domain, for example Grasslands National Park and the Old Man on His Back Prairie and Heritage Conservation Area in Saskatchewan, and in 2006, 30 wood bison were relocated to the Republic of Sakha (Yakutia) to begin repopulation efforts of the area historically inhabited by the now extinct steppe bison.

Bison conservation - Elk Island National Park has a prominent history in large ungulate conservation. As early as 1907, the Canadian government bought one of the last and largest remaining pure-bred plains bison, the Pablo-Allard herd, from Montana. Close to 400 bison were shipped to Elk Island as a temporary waystation until the fencing at Buffalo Park in Wainwright was completed. In 1909 the fence was finished and 325 bison were relocated to Buffalo National Park. However, 50-70 bison evaded capture and became the ancestors of today's herd in Elk Island National Park. In 2007, there were an estimated 425 plains bison in Elk Island.

1. In the late 19th century, only 300 wood bison remained worldwide, almost exclusively in Wood Buffalo National Park. During the 1920s, 6000-7000 plains bison were also relocated to Wood Buffalo National Park. These bison were not only infected with brucellosis and tuberculosis, which infected the wood bison herd, but the wood and plains subspecies also interbred, and thus it was thought that wood bison were completely extinct by the 1940s. In 1957, however, a disease-free, wood bison herd of 200 was discovered near Nyarling river in Wood Buffalo National Park. In 1965, 23 of these bison were relocated to the south side of Elk Island National Park and remain there today as the most genetically pure wood bison remaining. In 2007, the wood bison population in Elk Island National Park was estimated at 315.
