Gwinnett County dedicated Karina Miller Nature Preserve in 2005 on land purchased from the Miller family. The preserve includes 200 acres of land to remain undisturbed for future generations. It contains a variety of wildlife including mammals, birds, reptiles, amphibians and fish. A list of animals found in the preserve was part of an Eagle Scout project by Sam Putinsky of BSA Troop 1595 in 2013.
