Universitas Sumatera Utara competes with various other campuses to win the title of the best Green Campus through the UI Green Metric ranking. Tree vegetation at USU is also an added value for the campus. The campus is a favorite location for people to visit and enjoy the environmental services. The interest of visitors who come is certainly an opportunity as well as a challenge for USU to continue maintaining and developing tree vegetation which is a provider of environmental services for the surrounding. Therefore, research on the potential nature interpretation activities in green space at USU needs to be done and studied further. This study used field observation techniques by visiting various locations. Field findings data are described descriptively and tabulatively. The green space of USU has various potential locations for nature interpretation and environmental education, such as; bird watching, rare vegetation species, fruit spots, sports, photography, wildlife behavior, and flowering periods of vegetation. The results are expected to be useful in the learning process about the environment for the academic community and visitors who come, efforts to maintain a microclimate, develop further research, and support efforts to mitigate global warming.
