My Colby-Sawyer Experience

“My Capstone experience allowed me to ask questions that have not yet been answered and actively engage in finding answers to them.”

Yellow Birch Betula Alleghaniensis
Birch Betulaceae family

Leaves are egg-shaped, coming to a point at the tip, many small teeth along the margin, and 1-5" long. They are a "flimsy" sort of leaf. In the fall, these leaves turn yellow.

Flowers are in the form of flowering catkins that are narrow and approximately 1 1/8" long, and grow longer in the spring.

Fruit is also a catkin, like the flower, but this one is "fatter" and shorter (approximately 1/2" wide x 1" long), sort of like the end of your thumb.

Bark: Yellow birch bark is shiny and yellow or silver-gray, and peels in narrow strips.

Form/Habitat: Yellow birch is common in this area, and it is often found in the woods along with sugar maple, hemlock, and hobblebush. It is a fairly large tree (70 - 80') with a 2-3' diameter.

Winter identification: Yellow birch twigs are brown with tiny whitish dots that give it a "bumpy" feel. When you break the twigs or scratch the surface, they smell like wintergreen (black birch has this characteristic also). Both the twigs and buds are somewhat hairy; this is most easily detected with a hand lens.
