Hemlock Hill, the largest Arboretum woodland, occupies 22 acres. It has had a complex history of disturbance, including the 1938 hurricane and arrival of the hemlock woolly adelgid. This woodland is home to a number of unique birds, amphibians, ferns, and herbaceous perennials that prefer the shady understory of dense forestland. Prominent non-native plants include glossy buckthorn (Frangula alnus), castor aralia (Kalopanax septemlobus), mountain ash (Sorbus spp.), and hawthorn (Crataegus spp.). Hemlock Hill collections inform research and feature prominently in ecosystem studies for Boston Public School fifth grade students.
