About This Project

For my Sustainability Capstone project, I decided with the help of T. Dana Jensen to create a guidebook for the arboretum. With the help of T. Mary Brooks from the archives, I was able to build upon the work of the many Westtown students and teachers who have helped catalogue the arboretum over the years. In this book, you will find information and measurements for the many trees in Westtown's arboretum. While I have put my effort into every tree, I am hopeful that this book is incomplete, and that many students after me will continue to add their work.

I'd like to thank the Westtown Science Department for their generous lending of materials for this project. I would also like to thank my Environmental Sciences Teacher T. Dana Jensen, T. Mary Brooks from the archives, and T. William Addis, my advisor.

The American Arborvitae, also known as the Northern White Cedar, is a conifer indigenous to North America. For centuries, it has been used to build canoes because of its strong, lightweight wood. The American Arborvitae was also used medicinally by Native Americans. Its leaves have a distinct, pleasant scent that is released when they are squeezed, hence the scientific name "thuja", meaning perfume. Westtown has a small grove of five American Arborvitae.

The American Hornbeam is a deciduous tree endemic to the Eastern United States. Because of its unique shape, it is also commonly known as Musclewood. It has extremely durable wood, and was used in the early Americas to produce ox yokes, bowls, and tool handles. Despite this fact, it is not in wide use commercially because of the very small amount of wood that can be harvested from each tree.

The Amur Cork Tree near the cabin is known for its sour smelling berries. It is a deciduous tree, and flowers appear in the Spring. The tree is known as "Huang Bai" in China, where it is considered an essential herb in the Chinese herbalist tradition. It used to treat meningitis, conjunctivitis, and other conditions. It is alleopathic, meaning its roots release chemicals that alter soil composition, making it harder for other plants to grow.

This 65 year old Arizona Pine is over 20 meters tall. This species is a subset of the much more common Ponderosa Pine, mostly seen in the Southwest in places like New Mexico, Arizona, and some parts of Texas. It's thick bark and ability to recover from scorch damage protect it from the wildfires common in the Southwestern United States, making it fire-resistant. It has winged seeds enclosed in small pinecones.

The Blue Ash is a critically-endangered species of ash tree, which as a whole have been devastated by Emerald Ash Borers. They are insects that feed on Ash Trees, often choking them internally by blocking the xylem and phloem of a tree. The mortality rate for a Blue Ash with EAB is nearly 100%. Westtown's Blue Ash is one of the 90 preserved in Arboretums and Botanical Gardens worldwide. They are extremely rare in the wild and efforts to conserve them have been ineffective. If is continues to decline at this rate it will mostly likely become extinct in its natural habitat.

It also has white flowers that bloom in Spring, usually sometime between May and June. This tree is important ecologically because of the food and shelter it provides for birds, who often build nests in the trees and eat its fruit.
