Wood bison

Appearance

In comparison to plains bison, wood bison is larger and heavier, with large males reaching 3.35 m long including 54 cm tails and 201 cm tall at withers and 1,179 kg in weight, making it morphologically more similar to at least one of chronological subspecies of ancestral steppe bisons and the heaviest living terrestrial animal in North America.

The highest point of the wood bison is well ahead of its front legs, while the plains bison's highest point is directly above the front legs. Wood bison also have larger horn cores, darker and woollier pelages, and less hair on their forelegs and beards.

On the other hand, plains bisons are capable of running faster and longer than bisons living in the forests and mountains.

Naming

The term "buffalo" is sometimes considered to be a misnomer for this animal, as it is only distantly related to either of the two "true buffalo", the Asian water buffalo and the African buffalo. However, "bison" is a Greek word meaning ox-like animal, while "buffalo" originated with the French fur trappers who called these massive beasts , meaning ox or bullock—so both names, "bison" and "buffalo", have a similar meaning. Though the name "bison" might be considered to be more scientifically correct, as a result of standard usage the name "buffalo" is also considered correct and is listed in many dictionaries as an acceptable name for American buffalo or bison. In reference to this animal, the term "buffalo" dates to 1635 in North American usage when the term was first recorded for the American mammal. It thus has a much longer history than the term "bison", which was first recorded in 1774. The American bison is very closely related to the wisent or European bison.

Status

In addition to the loss of habitat and hunting, wood bison populations have also been in danger of hybridizing with plains bison, thereby polluting the genetic stock.

As with other bison, the wood bison's population was devastated by hunting and other factors. By the early 1900s, they were regarded as extremely rare or perhaps nearly extinct. However, a herd of about 200 was discovered in Alberta, Canada, in 1957. This herd has since recovered to a total population around 2500, largely as a result of conservation efforts by Canadian government agencies. In 1988, the Committee on the Status of Endangered Wildlife in Canada changed the subspecies' conservation status from "endangered" to "threatened," where it remains.

On June 17, 2008, 53 Canadian wood bison were transferred from Elk Island National Park in Alberta, Canada, to the Alaska Wildlife Conservation Center near Anchorage, Alaska. There they were to be held in quarantine for two years, and then reintroduced to their native habitat in the Minto Flats area near Fairbanks, but this plan was still on hold until April 7, 2015. In May 2014, the U.S. Fish and Wildlife Service published a final rule allowing the reintroduction of a "non-essential experimental" population of wood bison into three areas of Alaska. The new regulation took effect June 6. The Alaska Department of Fish and Game introduced the first herd of 100 animals to the Innoko River area in western Alaska in spring 2015.

Currently, about 7000 wood bison remain in the wild, located in the Northwest Territories, Yukon, British Columbia, Alberta, and Manitoba.

In 2006, as part of an international conservation project, an outherd was established in Yakutia, Russia, where the related steppe bison died out over 6000 years ago. Additional bison were sent from Alberta in 2011 and 2013 to Russia bringing the total to 120.
