Extension personnel often receive questions regarding identification of a particular tree. Digital photography, email, and text messaging make submitting specimens for identification very quick and easy.

 

Digital Photography

  1. Take close-up, clear photos of the specimen with a digital camera. Please consider the following:
  • Select a specimen that shows as many distinguishing characteristics of a species as possible. These would include leaves, twigs, flowers, fruit, bark, form, and position in the landscape.
  • If there is dramatic variation in leaf shape on a single plant, include photographs of all leaf shapes (Figure 1).
    A hand holds a tree limb to better display the leaves on the branch.

  • Unique characteristics are particularly important to include, such as thorns, twigs and branching patterns, or fruits and nuts (Figure 2).
    Maturing fruit on the limb of tree. Capturing blooming flowers or fruit on a branch can further help experts identify a tree properly.

  • Include a photograph that shows the characteristics of the bark (Figure 3).
    Tree bark varies among trees and should be captured at close range to help experts identify the tree for proper classification.

    • Make note of the type of site on which the tree is growing (wet, dry, flooded, etc.)
  • Finally, send a photograph of the tree in the landscape to show its form (Figure 4).
    The full height of a tree is pictured in a forested area. To help experts identify a tree properly, ensure that a photo of the tree is taken within in its landscape and next to other trees for comparison.

    • If necessary, crop photos to reduce their size or use a medium-quality setting.
  1. When sending your photographs to Extension personnel, include your contact information and any description you would like to provide about the plant, such as its size, history, or habitat. If you like, you may use the Tree Identification Request Form on the back. Send photographs via email to your urban forest inventory facilitator/coordinator/team leader, or regional Extension Forestry Specialist.
