In September 2013, Corps retiree Noble Enge’s sisters deeded land to North Florida Land Trust in his name, to ensure its permanent protection and preservation. The Noble Enge Trust encompasses 500 acres, much of it classic salt marsh habitat near and adjacent to the Nassau River on North Main Street in Jacksonville, Fla. within the Timucuan Ecological and Historic Preserve. "When you spend your life on a river, you can't help but want to see it preserved."
