  • A second life for leaves

    In a pilot study, Facilities and Real Estate Services is working with soil scientists and ecologists to take a scientific approach to managing campus land.
    Two researchers stand in a roped-off area of land, backlit by the rising sun. A study site marked with pink flags is at their feet.
    Eliza Nobles, a Morris Arboretum intern, and Jessie Buckner, an ecologist with Applied Ecological Services, set up the first plots at Penn Park on a sunny morning in October. Their study will examine how using leaf mulch or allowing fallen leaves to remain on a site impacts soil health and ecology.
