Photos of Dormant Winter Tree Markers

Identifying a dormant tree is not nearly as complicated as it might seem at first glance. Dormant tree identification will demand some dedication to apply the necessary practice to improve the skill of identifying trees without leaves.

I have compiled this gallery to augment your study of trees in winter to better identify tree species. Use this gallery and follow my instructions in A Beginning Guide to Winter Tree Identification. Using your powers of observation, you will find a pleasurable and beneficial way to enhance your skills as a naturalist - even in the dead of winter.

Learning to identify a tree without leaves can immediately make your growing season trees easier to name.

Vegetative structures on a tree are all important in its identification. The tree twig can tell you a lot about the kind of tree your are looking at.

The Terminal Bud:

The Lateral Buds:

The Leaf Scar:

The Lenticel:

The Bundle Scar:

The Stipule Scar:

The Pith:

One bit of caution when using the above markers. You need to observe an average-looking and maturing tree and stay away from root sprouts, seedlings, suckers and juvenile growth. Rapidly growing young growth can (but not always) have atypical markers that will confuse the beginning identifier.

Opposite or Alternate Twigs and Leaves

Leaf and Twig Arrangements
Trees that have Opposite or Alternate Twigs, Limb and Leaf Arrangement Leaf and Twig Arrangements. USFS Illustration

Opposite or Alternate Twigs: Most tree twig keys start with the arrangement of leaf, limb and buds.

It is the primary first separation of the most common tree species. You can eliminate major blocks of trees just by observing its leaf and twig arrangement.

Alternate leaf attachments have one unique leaf at each leaf node and typically alternate direction along the stem. Opposite leaf attachments pair leaves at each node. Whorled leaf attachment is where three or more leaves attach at each point or node on the stem.

The opposites are maple, ash, dogwood, paulownia buckeye and boxelder (which is really a maple). The alternates are oak, hickory, yellow poplar, birch, beech, elm, cherry, sweetgum and sycamore.
