The Summer Internship Program is sponsored by the New Canaan Racquet Club. For months, New Canaan resident and Eagle Scout candidate Josh Trepanier quietly worked behind the scenes to improve one of the town’s preserved open spaces. Trepanier designed and built a new interpretive kiosk at the New Canaan Land Trust’s Browne Preserve while organizing a volunteer day in which fellow Scouts removed more than nine large leaf bags of invasive plants and replaced them with native species donated by Copia Home & Garden. The project, which took more than six months of planning, will leave a lasting impact on both the preserve and those who visit it, according to Robin Bates-Mason, executive director of the New Canaan Land Trust. “Projects like these are incredibly valuable to organizations like the New Canaan Land Trust because this is going to be the next generation of young leaders,” Bates-Mason said.
