We received an additional supplement of Wood Bison in and have since had successful birthing seasons of our own herd mates. The Wood Bison currently receive the majority of our land as well as our efforts at the Alaska Wildlife Conservation Center as we aim to reintroduce a once historic breed back into the wilds of Alaska. The herd has had successful calving seasons in and in the wild.
Expert Advice First Trip to Alaska? How to Plan and Book? They have a dense coat of soft, durable hair that is not hollow like moose caribou and sheep, but is more like human hair. The hair color ranges from dark brown to black along the legs and lower body, to light brown along the hump.
Wood bison begin to lose their winter coat as temperatures warm in the early spring. By mid-summer the coat is completely shed and has been replaced with new hair.
Plains bison B. A small population of plains bison was established in near Delta Junction, thousands of miles from their natural range. A wood bison's hump is taller and has its highest point forward of the front legs. The wood bison has woolly hair along its ribs, where plains bison have very short hair.
The hair of the wood bison's beard, throat latch, ventral neck mane, chaps, and penis tuft are much less developed than that of plains bison. Wood bison vocalizations are different vocalizations from those of plains bison, and the wood bison's social interactions during the rut tend to be less violent than plains bison. All of these differences are evidence of the wood bison's adaptation to its northern environment: pockets of grassy meadow habitat within the sea of boreal forest, where temperatures can be quite cold and snow can be deep for extended periods.
Female wood bison are sexually mature around 2 years old and can have their first calf when they are 3. They generally have a single calf, twice in every three years.
Wood bison are pregnant for nine months and can give birth from April to August, with most calves born in May. Newborn calves are reddish in color, similar to moose calves. In order to evade predators, calves can stand within 30 minutes of birth and can run and kick within hours. After a week, calves will begin grazing but will continue to nurse for several months. After 10 weeks, their coats begin to darken to a deep brown by about 15 weeks of age.
Wood bison are primarily grazers, mainly eating grasses, sedges, and forbs. They can also use a variety of other plants; for example, silverberry and willow leaves make up part of their summer diet. It felt like I was looking through a portal into a lost world. I slowly rode east, too scared to stop pedaling. Wood bison, one of the two subspecies of American bison the other is the more famous plains subspecies and the largest terrestrial mammal in North America, were listed as extinct during the last century.
Wood bison, according to the U. Fish and Wildlife Service numbered around , in the early s and inhabited much of the taiga of Alaska and northwest Canada. In , a herd of a couple hundred wood bison were discovered in northern Alberta.
The U. Their diet is made up mainly of various grasses and forbs like vetch, a favored summer food found on gravel bars. They also eat sedges, silverberry, willow, and ground birch. Bison are migratory animals with seasonal movement patterns. They do not remain in single herds, but scatter alone or in groups ranging up to 50 animals or more. In the Delta Junction area, they migrate up the Delta River corridor in early spring to secluded meadows where they calve.
In late fall, they move onto area farms and state lands where they remain throughout the winter. Note: Wood bison, a native bison species extirpated from Alaska in the s, have been reintroduced to the state and will eventually provide hunting opportunity.
