Calvin College has been named a Tree Campus USA by the . is a national program created in 2008 to honor colleges and universities for effective campus forest management and for engaging staff and students in conservation goals.

A deeply-held commitment

Calvin is one of just three institutions in the state of Michigan to earn this distinction (Western Michigan University and the University of Michigan are the other two). To be recognized as a tree campus, the college had to meet Tree Campus USA's five standards for sustainable campus forestry. They include maintaining a tree advisory committee, having a campus tree-care plan, dedicating annual expenditures toward trees, observing Arbor Day and holding service-learning projects related to trees for students.

鈥淭he Tree Campus USA award continues to highlight Calvin鈥檚 commitment to an attractive, functional and sustainable campus,鈥 said Bob Speelman, who is the supervisor of the college鈥檚 landscape operations and a certified arborist. 鈥淚t shows that we believe that trees have many more benefits than just aesthetics, and that caring for old, weathered, character trees is just as important as the fun in planting new ones for the next generation.鈥

An ongoing project

One of the ways in which the college has cared for its trees in recent years is through creating a , a detailed digital inventory of all 3,500-plus trees on the college鈥檚 main campus. See

This summer, students, under the direction of professor , will be working to extend that inventory to include trees in the college鈥檚 east of the East Beltline.

professor and some of his students have been involved with the the past few years. He says there鈥檚 great value in caring for the Creation.

鈥淲e鈥檙e not simply learning about trees, we鈥檙e learning more about how to be good stewards of the trees. It gives me great satisfaction to be involved in outdoor work and to feel connected to the land,鈥 said VanHorn. 鈥淭rees to me are majestic. They are a metaphor for how awesome God is.鈥

The Arbor Day Foundation, a nonprofit conservation and education organization of one million members, and Toyota have helped campuses throughout the country plant hundreds of thousands of trees.聽
