Welcome to the Bucknell University Arborertum


Thanks to more than a century and a half of wise stewardship, Bucknell's campus is graced by a magnificent landscape including hundreds of trees that pre-date the founding of the university. The Bucknell University Arboretum builds upon and will help continue this legacy.

The Arboretum grew out of a biodiversity survey of the Campus Greening Initiative and was established with the following goals in mind:

  • Maintain the aesthetic qualities of the campus landscape while enhancing biodiversity and promoting sustainability
  • Provide student research and teaching opportunities using the campus as a living laboratory
  • Promote education and public outreach in the areas of botany, ecology, and sustainability
  • Preserve historic and significant trees and restore native plant communities where possible

The initial step in establishing the Bucknell University Arboretum is a comprehensive tree inventory that can be viewed in an interactive map.  Three students: Daniel Wang (’10), Nick Gonsalves (’11) and Giorgina Alfonso (’12), worked with Professors Mark Spiro (Biology) and Duane Griffin (Geography) to map, identify, and measure over 1700 trees on campus and to assemble information on the characteristics, economic uses, biogeography, and invasive status of each species. Current student projects include the removal of invasive species and restoration on native plant communities within selected regions of the campus. 

This website is as a resource for the Bucknell community. We invite students, staff, and faculty, to use it and contribute to its development by creating and sharing material related to Bucknell’s campus environment. 

This project has been funded by The Wayne E. and Margaret S. Manning Internship in the Botanical Sciences.

American elm trees were one of the most common tree on Bucknell's campus until Dutch elm disease killed most of them. This is one of the few survivors. The Environmental College has recently led an effort to plant disease-resistant American elms on the Dana quad. The American persimmon tree's deeply divided and scaley bark plates is one of its most distinguishing characteristics.
