Plant Life in the Tundra

• Growing season only last 50 – 60 days.• Plants grow close to the ground and close

together for heat.• Lichen is a common fungus found on the rocks,

Caribou and Oxen love to eat it.• Many plants have dark red leaves to attract

sunlight.• Shrubs can grow when soil accumulates between

rocks.

Plants Life Cont.

• 1,700 + kinds of plants in the Arctic.• All plants are adapted to harsh winds and hard

and poor nutrition soil.• The plants can carry out photosynthesis in low

light and low temps.• There are no deep root systems because the

soil is lacking nutrients and the second layer is completely frozen.

provide moisture for plant life.

Human Influences

• Arctic: The human influence would be Pollution. There is an oil development near breeding grounds of the Siberian Crane pollutes the wetlands. Disturbance to birds nesting grounds, people move in, making the animals move out. Hunting of birds in the area. Lead shot poisoning. Hunters shoot these shots and then later found in the bottom of water bodies and waterfowls.
