Step-by-Step Guide

The bark of the black walnut can be recognized by its unique texture and pattern.

1. Look for the herringbone pattern and interlaced diamonds on the bark surface.
2. Compare the bark to that of ash or tulip poplar, noting the differences in texture.

The leaves of the black walnut are long and compound, making them distinctive.

1. Observe the long compound leaves with pairs of leaflets.
2. Count the number of leaflets, as black walnut will typically have more pairs than similar species like ash or hickory.

Twigs can provide essential clues in identifying black walnut trees.
