New year = new skills. Why not learn how to identify oak trees in winter?
In eastern North America, oaks can be divided into a few groups, including the red oak and white oak groups. In this image, white oaks are featured in the top row, while red oaks are featured in the bottom row.
Bark patterns among oaks within a particular group tend to be similar, though subtle (and sometimes major) differences do exist. For example, white oak and swamp white oak share similar bark features (platy, somewhat shaggy), while chestnut oak is more distinctive (ridged and deeply furrowed).
Looking at the bottom row, scarlet oak, pin oak, and northern red oak all have similar bark features, but the bark of northern red oak more consistently displays “ski track” patterns than the other two trees. The bark of black oak is characteristically dark.
If you find it challenging to identify oaks by bark alone, look for leaves still attached to the trees or those that have fallen near the base of the trunk. You can also look for acorns on the ground and try to determine which trees produced them.
With practice, your tree identification skills will improve and you’ll be glad you put in the work. After all, and to slightly modify something Ben Franklin once said, an investment in knowledge [of trees] pays the best interest.
(Note: If you’re thinking to yourself, “This guy left out a lot of oaks,” you’re right. The oak genus is large. Hundreds of oak species exist. Pictured here are 7 oaks that grow in my neck of the woods. It’s entirely possible I omitted your favorite. Feel free to mentally add it to the lineup.)
