Temperate Deciduous Forest

Temperate Deciduous Forest
  • Changing seasons
  • 'Deciduous' means exactly what the trees on these leaves do: change colour in autumn, fall off in winter, grow back in spring/ lose their leaves every year and grow them back again
    (Helps trees to survive winter)
  • Winter: form of recipitation- sleet, snow, hail
  • Average rainfall is 30-60inches per year
  • Average temperature is about 50F
Surviving the changing season
  • Special adaptations
    - Summer: broad leaves to capture energy from sun and convert to food
    - Autumn: Green chlorophyll in leaves begin to decompose, revealing brillant shades of reds, oranges, yellows
    - Winter: trees and plants become dormant
    - Spring: grows new leaves and begin photosynthesis again
  • primarily in the eastern half of the United States, Canada, Europe, parts of Russia, China, and Japan

What causes season
  • the tilt of the Earth's axis at different times of the years
    (sun rays hit different parts of the globe more directly)

Temperate Deciduous Forest animals
  • must adjust to cold winters and hot summers by hibernating, migrating, keeping active all winter
  • Includes Black bear, grey squirrel, raccoon, white-tailed deer, cardinal, yellow-bellied sapsucker

Colours of leaves in the fall

Black walnut and butternut Drop leaves before they turn

Ash Plum purple
Red maple, dogwood, sassafras, and scarlet oak Dark red
Sugar maple and sumac Flame red and orange
Oak, beech, larch, elm, hickory, and sycamore Tan or brown

Thanks, I did not know about Mark Hutchinson Temperate Deciduous Forest. It is a rapidly evolving area for me, but more interesting than I ever would have thought.
