About Shaw Nature Reserve
Shaw Nature Reserve, operated by the Missouri Botanical Garden, spans over 2,400 acres in the Ozark Corridor of Missouri. It serves as a premier destination for ecological restoration, native plant education, and nature exploration. The reserve features a rich mosaic of habitats, including tallgrass prairies, oak-hickory woodlands, glades, and wetlands.
History & Heritage
Established in 1925 as the Shaw Arboretum, the site was originally purchased to protect the Missouri Botanical Garden's plant collections from the smoke pollution of St. Louis. Over the decades, its mission evolved from a traditional arboretum to a center for environmental education and ecological restoration. In 2000, it was renamed Shaw Nature Reserve to better reflect its focus on native Missouri habitats and biodiversity conservation.
