only has about 1700 different types of plants
root systems of the tundra plants aren’t very deep; they are shallow and extensive to maximize the absorption of the little water it receives.Types of plants and special adaptations
tundra plants have are short height and they are often grouped together, or grow into mats to help stand against the wind
must be accustomed to the short growing seasons, low light intensity, and freezing temperatures.
Types of plants
mosses, lichens, grasses, and shrubs, all of which are adapted to the environmentPlants (cont’d)
Only has about 48 different species of land animals
many animals must quickly breed raise their offspring in the summer to take advantage of the warmer temperatures and increased food supplyThe types of animals their physical/ behavioral adaptations
Physical Adaptations pulled up
Animals have are thick fur or extra fat for better heat retention/absorption
Others hibernate in the winter because of the lack of food
Some animals (like birds and caribou) migrate to other regions to escape the cold winter temperatures.Animals (cont’d)
Aleutian Shield Fern pulled up
only plant species that is considered to be critically endangered
no clear reasons for its increasing rate of disappearance
so it is believed that its rarity is due to natural processes
overgrazing and tramplingEndangered Plant Species (cont’d)
Their habitats and migratory routes are being destroyed by road building, oil pipelines, mining, and loss of food sources.Endangered Animal Species (cont’d)
