  2. Chapter 20Tree Identification

  3. Learning to Identify Trees • Obtain field guide or computer program • Learn distinguishing features of trees • Characteristics of leaves, bark, flowers, seeds • Tree size and tree growth patterns • Identify trees by their scientific names: more reliable and universal • Common names may be applied to multiple species

  4. Tree Profiles • Listed alphabetically by common name on remaining slides for Chapter 20 • Not all species will be found in your region • Each species adapted to specific climates, moisture conditions, and elevations • Some trees in your region will not be on the list

  5. Hardwood Species • European Alder (Alnus glutinosa) • Large shade ornamental

  6. Hardwood Species (Continued) • American Beech (Fagusgrandifolia) • Large shade tree, produces edible beechnuts

  7. Hardwood Species (Continued) • American Hornbeam (Carpinus caroliniana) • Small in size, very strong used to make tool handles

  21. Softwood Species (Continued) • Redwood (Sequoia sempervirens) • Tallest species of tree in the world, species mature between 400 to 500 years old, yet are still harvested
