<human>: How can I tell what type of tree a limb is?
<bot>: You can look at the shape, size, and color of the limb to determine its species. If it has a smooth bark, it's likely a pine or fir; if it has rough bark, it's probably a deciduous tree such as oak, maple, or birch. Additionally, you can use clues from the leaves, flowers, and fruit that may be present on the limb to help identify the species.
