Baker Island is a small, uninhabited atoll located in the central Pacific Ocean. It is part of the United States Minor Outlying Islands and is approximately 1.5 square miles in size. The island is known for its sandy beaches and surrounding coral reefs, making it a significant area for marine biodiversity. Discovered in 1832, Baker Island was claimed by the United States in 1857. It is primarily used for wildlife conservation, particularly for seabirds. The island is also a part of the Pacific Remote Islands Marine National Monument, which helps protect its unique ecosystem.
