    1. Tree Identification Powerpoint

    2. Forested • The definition of forested (land that is forested or has trees growing on it): to be classified as forested (forestland) the area must be at least one acre and contain at least 10% tree cover. Project Learning Tree

    3. Question What percent (0-100) of New York State was forested in 1880 _________ percent 1946 _________ percent 1996 _________ percent

    4. Dendrology • ‘Dendro-’ from the Greek word meaning tree • ‘-ology’ meaning the study of • Dendrology is the study of trees and includes taxonomy, identification, silivical characteristics, ranges, morphology, and ecology

    5. Vocabulary • Taxonomy is the study of the classification of living things. • Morphology is the study of the shape, general appearance, or form of an organism. • Silviculture is the care and cultivation of forest trees. • Ecology is the study of the relationships between living and non-living things and their environment.

    6. What makes a tree a tree? • Heights at least 4.5 meters (about 15 feet) • Single dominant woody stem (trunk or bole) • Capable of diameter growth • Perennial plant (present at all seasons of the year)

    7. What makes a shrub a shrub? • Heights under 4.5 meters (less than 15 feet) • Multi-stemmed • Capable of diameter growth • Perennial plant

    8. Tree Identification By observing leaves

    9. Conifers vs. Deciduous

    10. Which is Which?

    11. Characteristics of Conifers • Needle shaped leaves • Seeds that develop inside cones • Evergreen – green year round • Gymnosperm, conifer, softwood • Examples: pine, spruce, hemlock, fir

    12. Examples of conifers Balsam fir Red pine Douglas fir White pine Fraser fir Scotch pine

    13. Needle like Scale like Conifer leaves

    14. Clusters Singles Conifer needles

    15. Deciduous Tree Characteristics • Broad flat leaves • Lose all leaves each year in the fall • Angiosperm (flowering plants), broadleaf, hardwood • Examples: oak, maple, beech, aspen, ash

    16. Deciduous examples Red oak Elm Honey locust Red maple White birch beech Crimson king Black locust

    17. Exceptions • Larch trees have cones and needles, but lose their leaves each year. • Yew trees have needle shaped leaves and are evergreen but have berries not cones. • Holly trees have broad flat leaves and it is evergreen.

    18. Leaf characteristics-deciduous • Leaf arrangement: whorl, alternate, opposite • Leaf type: simple or compound • Leaf edge: entire (smooth), lobed (projection), toothed (serrated) • Leaf texture: hairy, waxy, rough, smooth, thick, thin, etc. • Leaf shape: various

    19. Leaf Arrangement alternate opposite whorl

    20. Leaf TypeSimple vs. Compound

    21. Only one leaf blade Joined by its stalk to the woody stem Examples: maple, oak, aspen, beech Made up of several leaflets Leaflets are joined to a midrib that is not woody Examples: ash, walnut, sumac Simple Compound

    22. Simple or Compound?

    23. What is the leaf type?

    24. Leaf EdgeLobed , smooth, toothed?

    25. Leaf Texture

    26. Leaf Shape

    27. More characteristics to ID trees • Bark • Twigs • Flowers • Fruits/Seeds • Cones • Overall shape

    28. Bark • Color • Texture • Furrows • Age • Thorns

    29. Twig clues • Leaf scars aka buds are the places where the leaves used to be attached • Size color and shape of buds also useful to ID trees

    30. Flower clues • Shape • Color • Texture • Size

    31. Fruits & Seeds

    32. Cones

    33. Overall shape

    34. Used in day to day conversation Usually based on a characteristic or region of origin Sometimes named after the person who studied the species Often confusing Each species is uniquely identified Made up of two parts, the genus and species Groups similar individuals More accurate CommonScientific NAMES

    35. Scientific names • Two part name binomial nomenclature • Made up of the genus and the species • Written in italics • Example: Pinus strobus

    36. Leaf Observations

    37. Can you identify this leaf?
