Deciduous Forest

What is a deciduous forest?
Deciduous means “falling off or at a certain season”
Leaves fall off of trees in the winter

The Five Zones
The Tree Stratum
Small Tree and Sapling
Shrub
Herb
Ground

Where Are They?
Eastern North America
Middle Europe
Some parts of Asia
Chile
Eastern Coast of Paraguay
New Zealand
Southeastern Australia

Climate
The Deciduous Forest has a Moist Continental Climate
4 seasons
Generally mild (summer: 70 degrees, winter: 32 degrees)
Rainfall - 14 inches during winter and 18 inches during summer
Oceans cause climate

Soil
Fertile
Great agriculture regions are found here
Most deciduous forests found in North America are second growth forests

Threats
Air pollutants from burning fuels kill wildlife and poison the soil
Humans interfere with the cycles of natural forest fires

Threats Continued
Acid rain damages leaves and causes production of smaller fruit and less seeds used in reproduction.
Global Warming is steadily increasing temperatures which causes less precipitation. This leads to less growth in the forests.

More Threats
Clearing land for agriculture and logging
Human occupation
Introduction of non-native plants and animal species cause competition for food and habitats which results in the endangerment of native species
Mining causes forest not to re-grow on damaged and depleted soils

Animal Adaptations
The Downy Woodpecker has adapted to live in the deciduous forest.
Reinforced head and sharp beak
Barbed tongue
Ability to eat insects and berries outside of tree

Plant Adaptations
Flowering plants have adapted to living in the deciduous forest
Pollen for insufficient water supply
Showy flowers aid in capturing of pollen
