A waterfront habitat centrally-located in the Philadelphia region, The Navy Yard is home to over 2,000 trees, hundreds of shrubs and perennials, an array of wildlife, and more than 13,500 employees and 165 companies across a variety of industries. With a Level I arboretum accreditation, The Navy Yard will continue to acknowledge, protect and enhance 1,200 acres of a beautifully forested and historic campus within the heart of Philadelphia. The arboretum governance group will encourage the preservation and appreciation of this unique site by nurturing current tree species and making strides towards a diverse future collection. By cultivating connections between visitors and horticulture through education and demonstration, The Navy Yard is an interactive resource where visitors can appreciate and learn about ecology within the urban context of Philadelphia.

Some unique aspects of the collection on campus include several 100+ year old specimens of Platanus x acerifolia, Platanus occidentalis and Quercus rubra, as well as many mature Nyssa sylvatica, Liquidambar styraciflua, Quercus palustris, Quercus imbricaria and Acer saccharinum.  Among these massive specimens there are more than 1,600 juvenile or mid-maturity trees, including Acer saccharum 'Fall Fiesta', Quercus acutissima, and Cercis canadensis ‘Oklahoma’.  This ratio of mature to juvenile species demonstrates The Navy Yard’s commitment to the future canopy.
