This is a White Ash Tree, also known by its scientific name, Fraxinus americana. Although this name sounds complicated, it’s just Latin for “ash tree of America.”
The White Ash is a fast growing, relatively tall species that is best known for its wood. Prized for strength and flexibility, this wood is commonly used in baseball bats, furniture, and tool handles.
In the fall, you might see something that looks like tiny helicopters falling from this tree. These are actually the tree’s seeds. They are called samaras. Because they spin as they fall—in contrast to other seeds—they are carried by the wind and grow further away from the parent tree.
The Emerald Ash Borer
Sadly, although the White Ash Tree used to be very common throughout the Demarest Nature Center, it has faced a large population decline in the last few years. This is due to the emerald ash borer, an invasive beetle native to Asia. These bugs lay eggs in bark crevices on ash trees. Their larvae feed underneath the bark of ash trees, and emerge as adults after 1-2 years. Since the early 2000s, these insects have killed tens of thousands of Ash Trees across North America.
