Peterffy owns 500,000-plus acres of timberland across five counties in North Florida. The land is held in Peterffy’s Four Rivers Land & Timber and is believed to be the largest contiguous piece of undeveloped property in private hands east of the Mississippi River. It includes more than half of all the land in Taylor County. He also owns 32,000 acres of pasture land in southern Highlands County.
