A Walk in the Woods
by Mary Morton Cowan
Where I live, in the northeastern United States, more than 70 kinds of trees are native to our forests. Let's take a walk and identify a few common trees of the northeastern woods.
Beech trees of all ages have smooth, light-gray bark. Forest animals find beechnuts tasty.

You can recognize the sugar maple by the deep U-shaped notches on its large leaves. Its sap is collected every spring to make maple syrup.

Eastern white pines are the tallest evergreen trees in the Northeast: 100 feet tall or more. The branches are high, where they can get sunlight. As the tree grows, its lower branches die and fall off. Pine “leaves” are called needles, and they grow in clusters. White pines have five needles in each cluster. In Colonial times, many white pines were chopped down to make masts for sailing ships. Can you guess why?

Trees in the oak family are divided into two groups: white oaks and red oaks (strangely, red oaks are sometimes called black oaks). You can tell them apart by looking at their leaves: White-oak leaves have rounded tips. Red-oak leaves have pointed tips.

Can you guess why this tree is called a shagbark hickory? Underneath that shaggy bark is tough wood. Hickory was once used to make skis, wagon wheels, and tool handles.

Each leaf of an ash tree is about a foot long. It is called a compound leaf, because it is made up of seven to nine leaflets, all on one stem. Ash wood is used to make baseball bats.

The paper birch is sometimes called white or canoe birch. Its beautiful white bark grows in paper-thin layers. Woodland Indians stripped off large sheets to make canoes. Many birds peel off little strips for their nests.

Birch leaves turn a beautiful yellow in the fall.

There are many other trees to see. Discover some yourself the next time you go for a walk in the woods.
