Carver Preserve is 189 acres of primarily mangroves on Pine Island, along Big Jim Creek. The preserve connects to State and Calusa Land Trust conservation land, located to the north. With the acquisition of this preserve, the entire Big Jim Creek inlet is now protected.

The preserve is named in honor of Dr. Jack C. Carver, who passed away in 2010. Dr. Carver was a practicing physician in Southwest Florida for nearly four decades and served as the first medical director for Lee Health’s Emergency Medical Service. He was also an avid gardener and environmentalist, who purchased the original acreage for this preserve. After his passing, the preserve was named through the Conservation 20/20 Legacy Program when his family nominated the sale of this land to Lee County as a Conservation 20/20 preserve. The Calusa Land Trust additionally contributed $5,000 toward the acquisition of the preserve.
