Welcome to the Barton Arboretum of Medford Leas
With an abundance of caution as the guideline,
the walkways and trails of our Arboretum
are closed at present to visitors.
They are open for residents and staff to enjoy
with maintenance of social distancing of a minimum of 6 feet.
The Barton Arboretum and Nature Preserve of Medford Leas is a unique blend of accessible public gardens, collections, and preserved natural areas set amidst private residential space. With campuses in Medford and Lumberton, NJ, spanning more than 200 acres, the Arboretum offers visitors a diverse horticultural array of designed gardens, landscaped grounds, meadows, natural woodlands and wetlands, and one of the most extensive plant collections — including natives — in all of southern New Jersey.
Accreditation
The Barton Arboretum and Nature Preserve holds Level 1 Accreditation from the Arbnet Arboretum Accreditation Program. The program is an international initiative, sponsored by the Morton Arboretum in cooperation with the American Public Gardens Association and Botanic Gardens Conservation International. As Jane K. Weston, former Director of Development and Community Relations at Medford Leas, said in response to the accreditation by ArbNet:
“The ArbNet accreditation provides a benchmark to assess our strengths as well as to identify areas for future development of the Barton Arboretum and Nature Preserve of Medford Leas. Residents and staff of Medford Leas have long been proud of our Arboretum, and the ArbNet accreditation serves as recognition of the work we have done over the years. We are proud to have attained this designation and to be in the company of so many well-regarded arboreta.”

The Annual Lewis W. Barton Arboretum Lecture, followed by refreshments and Alfresco Shop, 12 noon – 1:30pm
Our parks and wildlands are too small and disconnected to sustain native ecosystems on their own. To address this, we must practice conservation in our everyday spaces—yards, communities, farms, and ranches. Homegrown National Park (HNP) is a challenge to restore 20 million acres by reducing lawns, planting natives, and removing invasives. This movement aims to create diverse ecosystems in urban and rural areas, protecting vital species. Small actions from many people can help restore ecological networks and safeguard our life-support systems.Doug Tallamy is the T. A. Baker Professor of Agriculture in the Department of Entomology and Wildlife Ecology at the University of Delaware, where he has authored 112 research publications and has taught insect related courses for 44 years. Chief among his research goals is to better understand the many ways insects interact with plants and how such interactions determine the diversity of animal communities. His books include Bringing Nature Home, The Living Landscape, co-authored with Rick Darke, Nature’s Best Hope, a New York Times Best Seller, The Nature of Oaks, winner of the American Horticultural Society’s 2022 book award. In 2021 he cofounded Homegrown National Park with Michelle Alfandari (HomegrownNationalPark.org). His awards include recognition from The Garden Writers Association, Audubon, The National Wildlife Federation, Allegheny College, Ecoforesters, The Garden Club of America, The Herb Society, and The American Horticultural Association.
