Arboretum

What is it? The Patriot Tree Project is an initiative to document the trees and ecological communities on the George Mason University Fairfax campus (Figure 1). Faculty and students in the Department of Biology began this project in 2015, with support from the Patriot Green Fund, as an opportunity to educate the broader Mason community about the biological diversity of campus and its value for ecosystem and human health.

Figure 1. The Fairfax campus is a mosaic of disturbed forests (green areas in map) within a highly-managed landscape.

Where is it? Over 70 native and non-native trees located on the Fairfax campus have been identified and labeled (Figure 2, Table 1). The black, rectangular labels are attached to the trunks of the majority of these trees and are visible from sidewalks. Scientific vouchers for each tree have been deposited in the university herbarium to verify identification and key ecological measurements, such as height and DBH, have been recorded for future reference. Data files can be downloaded from links below.

Figure 2. The Arboretum is divided into three walking trails: West Campus, North Campus and South Campus.
