Nature and landscape have been integral to Vassar’s culture, campus, and curriculum from the inception of the college. Its site in the Hudson Valley has long been naturally enriched by lakes and creeks, and surrounded by gentle ravines, hollows, farmland, grasslands, and woods, creating a striking range of landscape types, as well as ecological diversity. Today there are over 2600 trees spread across the campus, representing over 170 species.

Visitors to the arboretum will see the central greensward conceived by John Charles Olmsted (1896), the country’s second oldest Shakespeare Garden, constructed by Vassar students studying Shakespeare and Botany (1916); and the Edith Roberts Outdoor Ecological Laboratory, established to showcase native plant communities, and the first of its kind (1920). The 525-acre Preserve, home to over 600 species of vascular plants, is adjacent to the main campus and accessible via several walking trails. Faculty and students from across the curriculum draw on the arboretum for their research. Each year, Arbor Day celebrations include the ceremonial planting of a Class Tree, and other tree celebrations and dedications.

Past Events

A large poster titled "Tree Stories" is displayed prominently, featuring images of leaves and tree-related information. Two individuals are engaged with the poster, one wearing a bright red jacket and the other in a green and gray outfit. The background consists of wooden paneling, and the space is illuminated by soft, natural light. Various leaf cutouts are attached to the board, along with printed materials discussing tree history and a local tree museum.

In 2020, the Vassar Arboretum was accredited as an ArbNet Level II Arboretum, which is characterized by a minimum of 100 species, varieties or cultivars of trees or woody plants. These must be planted and grown in accordance with an arboretum plan with a clearly defined purpose and audience, and provisions for maintenance and care in accordance with certain standards, including a policy on invasive species. This accreditation also stipulates a governing group dedicated to the arboretum plan and staff to maintain it, as well as collections inventory and record-keeping practices. Public access, information on the plants, and programming are other key components.
