Tree identification key

An interactive key for identifying UK trees

Keys are simple tools used for identification. They work as a series of question-and-answer steps leading to an identity or name.

  1. Select the statement that best describes the tree you are looking at. Remember the image illustrates the statement, not your tree. If you need to, you can go back to an earlier step by selecting it.
  2. Continue until you reach an identification.
