Distinguishing Common Oak Tree Species

 More on distinguishing tree species after the leaves fall.  Identifying oak tree species: 

 

1. Northern Red Oak (Quercus rubra). Key Features: The bark appears striped on older trees due to these shiny ridges, especially noticeable in sunlight.

2. White Oak (Quercus alba). Key Features: The overall appearance is lighter and ashier compared to other oak species.

3. Scarlet Oak (Quercus coccinea). Key Features: The inner bark is reddish, visible when cut or scratched, and the furrows are not as deep as in other oaks.

4. Black Oak (Quercus velutina). Key Features: The deep ridges and orange inner bark are diagnostic. Bark becomes almost furrowed like an alligator’s skin with age.

5. Chestnut Oak (Quercus montana). Key Features: The deep furrows and thick, rugged plates make it one of the most textured oak barks.

6. Swamp White Oak (Quercus bicolor). Key Features: The two-tone bark (lighter, peeling upper bark, and darker, furrowed lower bark) is a defining characteristic.

7. Pin Oak (Quercus palustris). Key Features: The smoother appearance of mature bark distinguishes it from more deeply furrowed species like black or chestnut oak.
