The flora of Loggerhead Key includes mangrove, coconut palms, geiger trees, morning glory, sea lavender and cactus. In the 1840s, the island was covered with white buttonwood trees, which were burned or cut down by island inhabitants. Bay cedar existed on the island in the early 1900s.
The Carnegie Marine Biological Laboratory, also referred to as the Tortugas Laboratory, was a marine biology laboratory and research facility constructed on the northern end of Loggerhead Key that operated from 1904 to 1939. It was constructed and operated by the Carnegie Institution of Washington. The Carnegie Marine Biological Laboratory performed some of the first research on Western hemisphere mangroves and coral reefs, marine life at the Loggerhead Key coral reefs, other marine life, and also performed underwater color and black-and-white photography there. Due to safety concerns regarding the hurricane season, research only occurred in the late spring and summer months.
