Donate to the Arboretum

Beginning even before the Arboretum’s dedication in 1934, Aldo Leopold and many other visionary scientists created a pioneering place for research, land care, and the restoration of ecological communities. Today, the Arboretum’s 1,200 acres in Madison includes restored ecological communities, horticultural collections, native plant gardens, and more than 20 miles of trails. The Arboretum also manages more than 500 acres of remnant outlying properties. Caring for more than 1,700 acres calls for experienced and knowledgeable land managers, scientists, students, and volunteers. Continual work, supported by community contribution, is needed to steward the land in our care, sustain our research initiatives, and provide a meaningful visitor experience. The majority of support for education and land care comes from individuals, organizations, and foundations. There are many ways to give, please explore the options listed here or contact us.
