The plains bison is a true ecosystem's engineer. Grazing, trampling the ground, wallowing in the mud and defecating, the bison shapes the landscape and creates conditions and various habitats which benefit to other species. Insects, animals, and indigenous plants depend on this ecosystem's redevelopment.

 North-America's biggest terrestrial mammal, the bison lives in huge lands, which enables it to overwhelm predators during attacks. Rather peaceful-looking animal, males fight brutally during the rut period (mid-July / mi-August)
