Not for the weak
There are 2 different types of tundra: alpine and arctic. Arctic tundras are located in the Northern Hemisphere in areas such as Northern Canada, Greenland, and Russia where all of the soil is frozen so trees can't grow. Alpine tundras occur on mountains (ex. Colrado) where the altitude is so high that trees can't grow.
During the winter the average temperature is -18 F but can drop as low as -50. In the summer the temperature rises considerably up to around 54 degrees F. Tundras are very windy and winds often blow between 30-60 mph. There is minimal rainfall (6-10 in. per year).
Arctic moss stays near or even underwater in the tundra. It has tiny rootlets instead of deep roots and sends out spores to reproduce. This plant can live up to 9 years. It adapts to the cold climate by storing nutrients during winter so it can grow as many leaves as possible in the spring. The more leaves the more photosynthesis. It also survives the wind by growing close to the ground or under water.
Is actually a lichen and grows on the rocks and the ground. It can make its own food when the temperature is low and there is little light and isn't at all damaged by frost. When conditions are too bad for growth they go dormant but can grow again after years of dormancy.
Pretty flower that only grows on southward slopes of alpine tundras. It grows low off the ground (only 6-8 in) to avoid harsh winds and cold
One of the largest and most beautiful of all owls. They make their nests out of frozen turf and moss on ridges or hills. Sometimes when food is scare nestlings are eaten by larger birds. Snowy owls are predators and help stop overpopulation. They eat arctic foxes, rabbits, lemmings, voles and other seabirds. They have good eyesight and sensitive hearing which allows them to find lemmings and voles under the surface and hunt them. They also have long broad wings that let them fly close to the ground to snatch their prey.
They are members of the deer family but are distinguished because of their elaborate antlers. Caribou have large hooves that allow them to move around in thick snow and marsh. They are good swimmers and can lower their metabolism and go into semi-hibernation when food is scarce. Caribou eat the leaves of shrubs, willows, and flowering plants and in the winter move snow around with their hooves to get to these plants
The Arctic fox makes it home in small burrows on frost free ground usually in mounds or rock piles. To avoid predators such as the snowy owl, wolves, and bears the fox has adapted stealthy movements and changes the color of its fur for camouflage. It has thick fur and short limbs that allow it to conserve heat. The arctic fox is an omnivore. It eats berries and shrubs when food is scarce but prefers to eat meat. The snowy fox is both a predator and a scavenger. It is the largest predator of lemmings and voles and helps manage their population. The arctic fox also will follow large predators such as polar bears and eats the remains of small mammals such as birds and fish. They keep the environment clean by eating dead animals and keeping rodents away.
