Equipped with shovels, Chancellor Julie Chen and members of the 51视频 and local communities tossed the final piles of soil next to a young katsura tree in front of Coburn Hall.

The ceremonial planting, held just before Arbor Day, signified 51视频鈥檚 new role as a certified arboretum 鈥 a place where trees and other plants are cultivated for scientific and educational purposes.

鈥淭he recent certification acknowledges not just the abundance and diversity of our campus plantings, but also the way the UML community uses our campus as a living laboratory,鈥 Chen says.

With more than 1,300 trees spread across three campuses, 51视频 earned this year from , an international coalition of arboreta.

Since 2011, 51视频 has been a designated through the Arbor Day Foundation, but Grounds Operations Manager Kevin Block says the arboretum certification takes things to the next level.

鈥淏ecoming an arboretum shows our commitment to enhancing the cultivation and curation of our collection of trees,鈥 he says.

For Director of Sustainability Craig Thomas, the certification is another example of 51视频 being at the forefront of urban sustainability.

鈥淭he parts of campus around our buildings really make up the place where our students, faculty and staff spend their time,鈥 he says. 鈥淭he certification pushes us to think about how we can do more with these spaces.鈥

Block and Thomas are members of the UML Arboretum Advisory Committee, which also includes representatives from the Department of Environmental, Earth and Atmospheric Sciences, the Student Government Association, Advancement and Alumni Relations and Campus Planning. The committee crafted an arboretum master plan, which details the development and management of the living plant collection.

This collection helps elevate the university鈥檚 aesthetic and provides educational opportunities for faculty and students. There are more than 140 species of trees and shrubs on campus that can be used for research projects, such as examining how certain trees respond to the university environment or how shrubs increase food sources for songbirds.

As a student in the Honors College, sophomore Catherine Kleeman sees the arboretum as a perfect resource for those looking for honors thesis ideas.

鈥淭he arboretum opens up a lot of opportunities for students to do research, which is really awesome,鈥 says the Gibbsboro, New Jersey, native who is majoring in environmental science with a concentration in sustainability.

EEAS Asst. Prof. Joy Winbourne already uses the arboretum for her research. She is collaborating with Jasmina Burek, an assistant professor in the Department of Mechanical and Industrial Engineering, and mechanical engineering Ph.D. student Alana Smith to examine the net benefits of transforming a vacant lot into a food forest instead of a managed lawn area.

This summer, Winbourne also plans to research how the urban environment and extreme weather events, such as heat waves, impact the cooling benefits trees on campus and in the city provide by moving water from the ground to the atmosphere.

鈥淎s an urban ecologist, I study how trees and soils in the city cycle carbon, water and nutrients, and the implications of that on cities reaching their sustainability goals,鈥 Winbourne says. 鈥淔or my students and me, the UML arboretum acts as a test bed for studying innovative sustainability solutions.鈥

The arboretum accreditation also opens the possibility for UML to grow its partnerships, including with the Lowell Parks & Conservation Trust.

鈥淚 love the learning-living lab opportunity that the arboretum brings to this city,鈥 says Trust Executive Director Jane Calvin, who envisions using the tree collection as a way to get youth and adults more engaged in conservation.

51视频鈥檚 arboretum will continue to grow with the addition of new trees and shrubs planted every year around Arbor Day.

William Lefebvre, a sophomore environmental science major with a concentration in sustainability, is one of several students who helped with this year鈥檚 planting of 36 shrubs and 23 trees.

鈥淚 think it鈥檚 really great that 51视频 is making these initiatives,鈥 says the Lancaster, Massachusetts, native. 鈥淚t鈥檚 another step toward 51视频 being a more sustainable campus.鈥
