Deciduous Forest

  1. 1. Deciduous Forest
  2. 2. What is a deciduous forest? <ul><li>Deciduous means “falling off or at a certain season” </li></ul><ul><li>Leaves fall off of trees in the winter </li></ul>
  3. 3. The Five Zones <ul><li>The Tree Stratum </li></ul><ul><li>Small Tree and Sapling </li></ul><ul><li>Shrub </li></ul><ul><li>Herb </li></ul><ul><li>Ground </li></ul>
  4. 5. Where Are They? <ul><li>Eastern North America </li></ul><ul><li>Middle Europe </li></ul><ul><li>Some parts of Asia </li></ul><ul><li>Chile </li></ul><ul><li>Eastern Coast of Paraguay </li></ul><ul><li>New Zealand </li></ul><ul><li>Southeastern Australia </li></ul>
  5. 7. Climate <ul><li>The Deciduous Forest has a Moist Continental Climate </li></ul><ul><li>4 seasons </li></ul><ul><li>Generally mild (summer: 70 degrees, winter: 32 degrees) </li></ul><ul><li>Rainfall - 14 inches during winter and 18 inches during summer </li></ul><ul><li>Oceans cause climate </li></ul>
  6. 8. Soil <ul><li>Fertile </li></ul><ul><li>Great agriculture regions are found here </li></ul><ul><li>Most deciduous forests found in North America are second growth forests </li></ul>
  7. 9. Threats <ul><li>Air pollutants from burning fuels kill wildlife and poison the soil </li></ul><ul><li>Humans interfere with the cycles of natural forest fires </li></ul>
  8. 10. Threats Continued <ul><li>Acid rain damages leaves and causes production of smaller fruit and less seeds used in reproduction. </li></ul><ul><li>Global Warming is steadily increasing temperatures which causes less precipitation. This leads to less growth in the forests. </li></ul>
  9. 11. More Threats <ul><li>Clearing land for agriculture and logging </li></ul><ul><li>Human occupation </li></ul><ul><li>Introduction of non-native plants and animal species cause competition for food and habitats which results in the endangerment of native species </li></ul><ul><li>Mining causes forest not to re-grow on damaged and depleted soils </li></ul>
  10. 12. Animal Adaptations <ul><li>The Downy Woodpecker has adapted to live in the deciduous forest. </li></ul><ul><li>Reinforced head and sharp beak </li></ul><ul><li>Barbed tongue </li></ul><ul><li>Ability to eat insects and berries outside of tree </li></ul>
  11. 13. Plant Adaptations <ul><li>Flowering plants have adapted to living in the deciduous forest </li></ul><ul><li>Pollen for insufficient water supply </li></ul><ul><li>Showy flowers aid in capturing of pollen </li></ul>
  12. 14. Links of Interest <ul><li>http://www.marietta.edu/~biol/biomes/tempded.htm </li></ul><ul><li>http://inchinapinch.com/hab_pgs/terres/d_forest/td_forest.htm </li></ul><ul><li>http://www.blueplanetbiomes.org/deciduous_forest.htm </li></ul>
