Fun Fact: Linda loves to travel and counts among her best wildlife experiences a safari in South Africa where she says, “We got close enough to hear the breath of the lions!”
Linda Mead‘s all-time achievements can be summed up in three words: Preservation, Stewardship, and Inspiration. The 22,000+ acres of land she has worked to preserve and protect are a gift to all of us who live and work in our region. Science tells us preserved land ensures cleaner air, more drinkable water, and the open spaces that will give us a running start in the race against climate change. Her innovative guidance of D&R Greenway from a grassroots organization to a national leader has left a significant impact on our region and beyond.
Mead’s enthusiasm for connecting D&R Greenway’s mission with people’s hearts and minds has resulted in substantial private/public partnerships to protect conservation lands and farms and has ensured a stable organization for the future. Her vision guided the creation of D&R Greenway’s Johnson Education Center in Princeton, NJ, surrounded by Greenway Meadows – whose permanent protection she spearheaded, purchasing the land from the General Robert Wood Johnson estate. Tenacious and determined to solve challenges, she persevered for six years to achieve permanent protection of a former Catholic orphanage in Hopewell; St. Michaels Farm Preserve is now a community asset enjoyed by thousands of people. Lands preserved through her leadership are known throughout New Jersey – from Farm View Fields in Princeton to Point Breeze, the former estate of the exiled King of Spain Joseph Napoleon Bonaparte. Her current challenge is guiding the strategic vision for a new preserve in honor of Betty Wold Johnson, a renown philanthropist whose sons donated her nearly 800-acre farm to D&R Greenway in 2021.
Nationally, Linda Mead partnered with a financial advisor to cofound an innovative national training program for land trusts and financial experts. Results include a mountain protected in Alabama and an innovative financing program in Colorado. Mead contributed to two studies that resulted in National Heritage Areas including the Crossroads of the American Revolution in NJ. She shares her visionary leadership sand expertise in structuring multi-party transactions by serving on the National Leadership Council for the Land Trust Alliance, the professional organization for more than 1,000 land trusts in the US.
Linda Mead’s innovative ideas led her to cofound the Delaware River Sojourn, now in its 27th year, and the Bucks County, PA Open Space Program. She has served on many Boards including Bowman’s Hill Wildflower Preserve and the State of New Jersey Historic Easement Advisory Board. She was a founding member of the Abbott Marshlands Cooperative Stewardship Council and of AWE – the Alliance for Watershed Education for the Delaware River. She partnered with a national business to publish five audio tours accessed on the free TravelStorys app. D&R Greenway’s Healing Trails tour inspired similar tours in hospitals for healthcare workers during the pandemic; and, a tour birthed during the 100th anniversary of women’s right to vote highlights Women in Conservation. A new tour, Seldom Told Stories along the Delaware River, will be released this fall.
Recognition with the 2022 Innovator of the Year Award by The Princeton-Mercer Regional Chamber of Commerce marks the 25th anniversary of Linda Mead’s leadership of D&R Greenway Land Trust. A graduate of Rutgers University, Ms. Mead has lectured on innovative conservation partnerships at the University of Notre Dame, Princeton University, Yale and Rutgers. Past awards include the 2002 International Paper Conservation Partnership Award presented by The Conservation Fund at the National Press Club; the 2004 NJDEP Governor’s Award for Environmental Excellence in Open Space Preservation; the 2013 Environmental Achievement Award from Plan Smart New Jersey; the 2013 Women in Wildlife Leadership Award from Conserve Wildlife New Jersey; the 2014 Zone IV Award from the Garden Club of America; the 2017 Mercer Women Leaders Environment Award from Mercer County Clerk Paula Sollami Covello; and YWCA Princeton’s 2018 Tribute to Women Award. In 2021, the Rotary Club of Montgomery/Rocky Hill, NJ recognized her achievements with a flag flown for 12 days at the national Flags for Heroes celebration at our nation’s Capital.
