Global Distribution

Page 3: Deciduous Forests

wildflowers grow on forest floor early in the spring before trees leaf-out and shade the forest floor

trees drop leaves in the autumn, and grow new ones in spring

trees have thick bark to protect against cold winters

Animal adaptations- hibernation and fur shedding/ growing depending on seasons

Birds migrate

Plant and Animal Adaptations

Temperature -30° to 30° Celcius

Precipitation 75-150 cm throughout the year

Soil is fertile

Seasons change- Summer, Fall, Winter, Spring

Climate
