Frick Park is home to many trees, shrubs, and flowering plants, among them sugar maples, juneberries, and forsythia.  Park Foreman Dick Wilford has removed more invasive trees from Frick Park compared to any other green space in the city.  Over the past 3 years, 325 Norway maples and 600 Trees of Heaven have been removed, allowing the out-competed natives in the understory to thrive. As invasives are removed, Wilford, DPW crews, and staff and volunteers from the Frick Environmental Center are planting hundreds of native trees including sugar and red maple, white pine, hemlock, red and white oak, sycamore, white ash, redbud, hawthorn, willow, and dogwood.
