Global Distribution and Adaptations of Deciduous Forest Ecosystems

This article explores the characteristics and adaptations of deciduous forests, highlighting the seasonal changes that define these ecosystems. In spring, wildflowers bloom on the forest floor before tree canopies emerge. Trees adapt to cold winters with thick bark and shed leaves in autumn, promoting a vibrant seasonal cycle. Animal adaptations such as hibernation and migration are crucial for survival. Despite their rich biodiversity, deciduous forests face threats from development, agriculture, and climate change, leading to a significant decline in their extent over geologic time.

  1. Deciduous Forests By TJ, Tessa, and Hannah

  2. Global Distribution

  3. Plant and Animal Adaptations 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

  4. Climate Temperature -30° to 30° Celcius Precipitation 75-150 cm throughout the year Soil is fertile Seasons change- Summer, Fall, Winter, Spring

  5. Threats • Development • Agriculture • Logging • Acid rain • Over hunting

  6. Changes over Geologic Time Amount of deciduous trees and forests has decreased No regional variations
