  • *All relevant terms are bolded.
  • Just like a group of houses don’t equate a city, a group of trees doesn’t equal a forest. A forest includes trees and all other plants and animals that interact to create the forest system.
    A forest is a balanced ecosystem in which trees and plants photosynthesize to generate food that is used by themselves and animals. Decaying plants and animals release nutrients that are taken up again by the plants.
  • Forests were a formidable barrier to European settlers in America. Forests had to be cleared to create room for crops.
  • Commercial forests are forests that have the potential to be economically productive. This doesn’t mean that the forest is being used this way. Much of the commercial forestland is in small parcels near homes or parks. Noncommercial forest might be on very rough terrain or on swampy land or be part of a park or preservation area. Much of the forestland of today is being taken over for urban and industrial development.
  • The terms softwood and hardwood have little bearing on the actual hardness of the wood!
  • Transcript

    • 1. Teacher Information!  Necessary materials:  PowerPoint Guide
    • 2. Our Forests and Their Products Pgs 235-242 in Ch.19 of Managing Our Natural Resources Rangelands, Forests, & Fire
    • 3. Students will be able to…   Define forest Describe the six forest regions in the U.S.
    • 4. The 1st Forestry Industry in the U.S.     Began with the 1st European to set foot in North America  Leif Ericson Leif and his Vikings established logging camps in northeastern Canada Harvested wood  shipped back to Europe 600 years prior to the settlers of Jamestown
    • 5. Forests  Occur where moisture is sufficient for tree growth    Arid regions like the Great Plains  too dry to support forests Complex community of trees and other organisms  forest House = tree, city = forest   A housing development ≠ city Clump of trees ≠ forest
    • 6. Forest: Friend and Enemy    Dense forests made farming & settlement difficult But trees supplied materials for houses, forts, and ships Source of wild game and fruit
    • 7. Forests Today  749 million acres in the U.S. forested = 1/3 of the U.S.  2/3 of this = commercial forest    250 million acres of commercial forest are actually usable 1/3 (250 million acres) = noncommercial forest Commercial  Forest that has economic potential
    • 8. Who owns commercial forestland?    Private landowners  58% Government  28% Forest product industries  27%    Weyerhauser, Kraft, Union-Camp Maine & New Hampshire > 80% forested Nebraska & North Dakota < 2% forested
    • 9. What trees are used in forestry?   Two general kinds  Softwoods    Hardwoods    Gymnosperms = conifers Douglas fir, blue spruce, yew Angiosperms = flowering, broad-leafed trees Oak, maple, beech, apple, cherry Most timber production  softwoods
    • 10. U.S. Forest Regions   Different species of trees have different requirements Different environmental conditions  forest regions     Climate Altitude Soil type 6 forest regions in continental U.S.
