  1. The Short, Short Course on Tree Identification Doug McLaren University of Kentucky Cooperative Extension Service Department of Forestry University of Kentucky – Cooperative Extension Service

  2. With so many species of trees… How do we learn how to identify each of them for our needs? University of Kentucky – Cooperative Extension Service

  3. Let us start with something we are familiar with… Characteristics Something that distinguishes or identifies an individual… University of Kentucky – Cooperative Extension Service

  4. University of Kentucky – Cooperative Extension Service

  5. Season of the year! University of Kentucky – Cooperative Extension Service

  6. Leaves – on - Method Broadleaf Conifer University of Kentucky – Cooperative Extension Service

  7. Conifers Flattened Needles per bundle (2 – 3 – 5) Cedar White pine (5) Pitch pine (3) Virginia pine (2) University of Kentucky – Cooperative Extension Service

  8. Broadleaf Arrangement of leaves and buds Alternate branching Opposite branching University of Kentucky – Cooperative Extension Service

  9. Form of the leaf Compound Simple University of Kentucky – Cooperative Extension Service

  10. Margins Entire (or unlobed) Serrated Lobed University of Kentucky – Cooperative Extension Service

  11. Conifer or broadleaf? TEST TIME! (1) Opposite or alternate? University of Kentucky – Cooperative Extension Service

  12. Simple or Compound? TEST TIME! (2) Alternate or Opposite? University of Kentucky – Cooperative Extension Service

  13. Margins! TEST TIME! (3) Serrated or Lobed? Entire or Lobed? University of Kentucky – Cooperative Extension Service

  14. In the process of identifying trees, there is a logical sequence to identify the correct tree… The “instrument” that is used to select the correct tree is a dichotomous key . University of Kentucky – Cooperative Extension Service

  15. What is a dichotomous key? A process in which to identify an organism based on a series of choices – two choices at a time! University of Kentucky – Cooperative Extension Service

  16. Example! …of a dichotomous key for tree identification • Does the tree have LEAVES – if so, GO TO B • A. Does the tree have NEEDLES – if so, GO TO C B. Is the branching pattern OPPOSITE – if so GO TO D B. Is the branching pattern ALTERNATE – if so GO TO E University of Kentucky – Cooperative Extension Service

  17. Dichotomous tree finder University of Kentucky – Cooperative Extension Service

  20. Where does it grow? University of Kentucky – Cooperative Extension Service

  21. Dichotomous Tree Finder An abbreviated example A. Does the tree have NEEDLES…Go To D A. Does the tree have LEAVES…Go To B B. Are the leaves SIMPLE…Go To C B. Are the leaves COMPOUND…Go To C C. Is the branching OPPOSITE…Go To E C. Is the branching ALLTERNATE…Go To F D. Probably a conifer E. Probably a maple or ash F. Service berry Amelanchier canadensis University of Kentucky – Cooperative Extension Service
