Animals
Bison: Bison were the most seen animals on the trail. They thought these bison were buffaloes. Sometimes the pioneers would like to look at the bison trample around the lands. They were also a great a source of food.
Snakes: Pioneers came across rattlesnakes, copperheads, and many more. The pioneers were mostly scared of these snakes. They would often try to kill them when they came across them because snake bites risked death.
Prairie Dogs: When pioneers saw Prairie dogs, they would always find a lot of them. Around 100. Pioneers would usually leave them alone since they were so quick it wasn't worth wasting the ammunition at them.
Rabbits/Bunnies: Pioneers saw other furry animals. They saw a bunch of rabbits. They wouldn't really mess with them since there was so much and they were such a small food source. But if they were starving, they would shoot them. They also lived in big packs like the prairie dogs.
Coyotes: Travelers on the Oregon trail often awoke at night to howling coyotes. These large dog-like creatures would steal meat from the pioneers when they were sleeping. The pioneers would not hunt them because they were usually too dangerous to mess with.
Beavers: When pioneers came to dams, they saw beavers. Beavers would be near the water in the rocky mountain area. Pioneers left them alone. Sometimes they would watch the beavers build their dam slowly when they stop for a rest. They were very entertaining to the Pioneers.
Plants
Pine: Near the end of the the journey, they would run into evergreen forests and come across pine trees.
Prairie grass: Prairie grass was food for the oxen. This was the reason they did not use horses to pull their wagon, because horses could not eat this type of grass, and this grass was the only they could find along the trail.
