Practice Your Tree ID

Identifying trees is a lot like identifying people. 

You can easily recognize a close friend even if you only catch a glimpse. However, if you meet a room full of strangers, you need to concentrate on individual characteristics before you can tell them apart.

It is the same with trees. When you know a tree well, you will be able to name it on recognition of the characteristics, or traits, such as: 

  • Leaves
  • Bark
  • Fruit (and sometimes flowers or catkins)
  • Twigs and buds - the primary identifier in winter!
  • Shape or form of the tree
