A Decade of Transformative Leadership in North Branford
David Sargent has been a driving force behind land conservation in North Branford for over a decade as President of the North Branford Land Conservation Trust (NBLCT).
Under his leadership, NBLCT has expanded protected lands, strengthened community engagement, and elevated the organization’s reputation. Despite limitations on available land due to Regional Water Authority ownership, David has successfully navigated complex negotiations to acquire key properties, including Harrison Farm Preserve, Starry Lane, Angeloni Woodland Preserve, and Beech Street & Pomps Lane. These efforts have preserved critical habitats, enhanced public access, and connected trails for recreation and education.
Beyond land acquisitions, David has played a vital role in conservation initiatives such as the Farm River Restoration Project, regional collaborations, and trail expansions. His leadership has revitalized NBLCT, making it a recognized force in conservation, and inspiring future stewardship. Through advocacy, fundraising, and hands-on efforts, David has transformed the land trust into a thriving organization, ensuring North Branford’s natural spaces remain protected for generations to come.

Fostering Community Connections with Nature
The Groton Open Space Association (GOSA) has made a lasting impact on land conservation through innovative community engagement initiatives. By fostering connections between people and nature, GOSA has increased awareness and appreciation for Groton’s natural resources.
A key achievement, led by Lynn and Dan O’Connell, is the GOSA/Groton Public Schools hiking program, which has introduced over 600 students annually to local open spaces since its launch in 2023. By securing grant funding to cover transportation costs, GOSA ensured that more students could experience hands-on environmental education. Teacher feedback highlights the program’s success in boosting student interest in science, outdoor activity, and ecological awareness.
Beyond schools, GOSA strengthens community ties through the “GO [Get Outdoors] Groton” partnership with the Town of Groton, leading to the town’s participation in the national Nature Everywhere program. They also organize monthly hikes, summer programs, and senior outings, making nature accessible to all.
Through these efforts, GOSA is cultivating the next generation of conservation advocates and ensuring Groton’s open spaces remain cherished and protected for years to come.

A Legacy of Transformative Leadership in the Housatonic Valley
Lynn Werner, Executive Director of the Housatonic Valley Association (HVA), has been a driving force in land and water conservation for over 40 years.
Under her leadership since 1995, HVA has expanded its staff, quadrupled its budget, and launched transformative conservation initiatives. She co-founded the Litchfield Hills Greenprint, played a key role in preserving over 5,000 acres through the Stanley Works project, and helped reroute the Appalachian Trail along the Housatonic River.
Lynn’s advocacy has shaped public policy, strengthening stream flow protections, wetland conservation, and strategic land preservation. She was instrumental in securing a settlement from General Electric for PCB contamination cleanup and helped achieve the 2022 Wild & Scenic designation for 41 miles of the Housatonic River.
A mentor and coalition-builder, Lynn has elevated regional conservation efforts, ensuring lasting environmental stewardship. As she retires, her legacy of innovation, collaboration, and unwavering dedication leaves an enduring impact on Connecticut’s natural landscapes and conservation community.
The recognition of David Sargent, the Groton Open Space Association, and Lynn Werner underscores the diverse and vital work being done to protect Connecticut’s natural heritage. Their achievements serve as a powerful reminder of the dedication and collaborative spirit that drives successful land conservation efforts across the state. Congratulations on your outstanding work.
