Harvard University
Cambridge, MA
70%
Harvard University Central Campus demonstrates a strong commitment to reducing synthetic inputs across a large and complex landscape. Their approach prioritizes native plant integration in rain gardens, bioswales, and pollinator spaces, alongside thoughtful soil-building practices like compost tea, aeration, and overseeding. The campus has also significantly invested in electrifying its grounds equipment fleet, with a clear path toward 100% battery-powered operations. Their engagement with students through landscape projects and sustainability dialogue further reinforces a culture of ecological stewardship.
While synthetic pesticides are already used sparingly and as a last resort, continued efforts to transition tree care and athletic field management toward fully organic alternatives will be key. Expanding pesticide-free management beyond 70% and further reducing reliance on synthetic treatments for tree health will support progress toward higher certification levels.
