NOTES ON VEGETATION PATTERNS
 
  • Two Main Categories of Vegetation
    • Crops
      • Plants grown by humans for human needs
    • Natural Vegetation
      • Plants grown without the involvement of humans, naturally
  • Key Factors that Influence Crop Growth
    • Soil conditions
    • Amount of moisture present
    • Amount of energy (temperature/sunlight) present
  • Major Types of Vegetation
    • Forest
      • Characterized by trees
      • Types of forest
        • Tropical Rainforest
          • found in the low latitudes
          • requires tropical wet climate
          • very dense, tall forest with hundreds of different kinds of trees
        • Deciduous Forest
          • found in middle latitudes
          • requires temperate climate
          • trees lose their leaves during a certain season of the year
        • Coniferous Forest
          • found in middle latitudes
          • requires temperate climate/colder
          • cone bearing trees
        • Mixed Forest
          • found in the middle latitudes
          • requires temperate climate
          • deciduous and coniferous forest blend
    • Savanna
      • characterized by tropical grassland with scattered trees
      • found in low latitudes
      • requires tropical wet and dry climate
      • located between tropical rainforest and desert
    • Desert
      • characterized by plants do not give off moisture easily and they retain water
      • found in low to middle latitudes
      • requires arid/dry climate
      • may be hot or cool
    • Grassland
      • characterized by various lenth grasses
      • found in middle latitudes
      • located between temperate forest and desert
      • types of grasslands
        • prairie
          • tall grassland
        • steppe
          • dry, short grassland
    • Tundra
      • characterized by mosses, lichen, low shrubs, and small flowering plants
      • found in high latitudes
      • requires very cold conditions with little moisture
      • permafrost
    • Barren
      • impossible for plants to grow
      • ice caps, ice and snow remain all year
