Located off the coast of southwestern Franklin County, where the Apalachicola River and several barrier islands form Apalachicola Bay. Apalachicola Bird Island is located about 0.5 miles (0.8 km) south of the western end of the John Gorrie Bridge. St. George Island Causeway is about 4 miles (6.4 km) long and connects the island with the mainland at Eastpoint. St. George Island is about 4?8 miles (6.4?12.8 km) south of the mainland; Dr. Julian G. Bruce St. George Island State Park occupies the eastern end of the island, about 4 miles (6.4 km) from the causeway. Cape St. George is between St. George Island and St. Vincent Island, about 6?8 miles (9.6?12.8 km) off the mainland. St. Vincent Island is the westernmost island, 0.25 miles (0.4 km) off the mainland at Indian Pass. Yent Bayou is on the mainland about 7 miles (11.2 km) east of Eastpoint and about 6 miles (9.6 km) west of Carrabelle Beach, bounded on the west by Royal Bluff. The Greater Apalachicola Bay IBA is just west of the Dog Island?Lanark Reef IBA.
Sea turtles nest along the beaches. ? The St. George Lighthouse, on Little St. George Island, was built in 1852. At that time, the lighthouse was 1330 feet (400 m) from the beach, but erosion of the island has brought the shoreline to its base. The lighthouse now is being stabilized to prevent its collapse. ? St. George Island State Park contains some virgin ?cat-faced? slash pines from the turpentine industry active in the early 1900s. ? St. Vincent Island National Wildlife Refuge is a breeding site for the critically Endangered ?red wolf (Canis rufus). ? Apalachicola Bay is a designated International Biosphere Reserve, and a National Estuarine Research Reserve.
The islands are regionally important for breeding and wintering waterfowl and shorebirds, and for breeding larids. Portions of St. George Island, St. Vincent Island, and Yent Bayou have been designated by the U.S. Fish and Wildlife Service as Critical Habitat for wintering Piping Plovers. Wooded portions of the State Park and Refuge support Neotropical migrants. Apalachicola Bird Island also supports breeding shorebirds. St. Vincent National Wildlife Refuge supports an apparently large population of Black Rails, and its hammocks are important for Neotropical migrants. The Refuge also marks the western limit for the dark-eyed subspecies of the Boat-tailed Grackle (Quiscalus major westoni; +McNair and Lewis 1999). Overall diversity is 273 native species; lists have been compiled for only St George Island State Park and St. Vincent National Wildlife Refuge.

Apalachicola Bird Island is posted from April through August to prevent disturbance to the breeding colony. The island is maintained as a bird nesting area by the U.S. Army Corps of Engineers by adding dredged material every few years. Cape St. George State Reserve: Prescribed fire is used to maintain the condition of pine flatwoods and savannas, and exotic plants are removed as needed. ? Dogs must be leashed at all times. ? The larid colony on the St. George Island Causeway is subject to high mortality from motor vehicles. To reduce bird deaths from vehicles, the speed limit on the causeway is reduced to 35 mph (56 kph) during the breeding season, and the colony is fenced to keep young birds off the road. A new bridge is being built between the mainland and St. George Island; when this is completed, the existing causeway will become an island managed for nesting birds. ? St. George Island State Park: Most of the dunes in the state park are off limits except along paths; private portions of the island are undergoing extensive development. ? St. Vincent National Wildlife Refuge contains populations of feral hogs and ?sambar deer (Cervus unicolor) native to southeastern Asia; these are remnants of previous owners who used the island as a hunting reserve. The deer are retained for recreational opportunities, while feral hogs are considered a pest species; numbers are controlled by hunting. ? Yent Bayou: Uplands are residential lots, which have begun to be developed. It is not known whether development of these lots will impact shorebird use of the tidal wetlands.
