Why are wood bison at risk?

The two main causes are believed to be over hunting  and extreme winters. A law preventing you to be able to hunt the wood bison was placed in 1877 which was later repealed. Later when the bison numbers dropped to around 300 animals in 1911 the law was reinforced. In 1922 the population had grew to about 1500 wood bison.

What do wood bison eat?

During the winter, a wood bison’s diet consists of different grasses and sedges which is a grass-like plant and forbes which are a species of herbaceous plant (plants that don’t have a woody stem). Wood bison also eat silverberry and willow Leaves in the summer.

Where do wood bison fall in the food chain?

Wood bison are primary consumers. They are hunted by wolves, mountain lions, and bears.

The Boreal Caribou is a species that is revered to the dark . This species is at risk due to human and natural changes in there habitat, increasing predator population and over harvesting. They are the largest group of caribou in Canada, their dark skin lets them hide in tall brush and stay protected from predators. They are primary consumers because they are herbivores, and they use their antlers and hooves to search and dig for food. They eat grasses, sedges, birch, berries, shrubs and tree lichens that they primarily find on the ground. It takes over 150 year for a forest to grow enough lichens for a Caribou. The male and female both grow antlers, however the females are smaller.
