The Island is also the site of the former U.S. military installation Fort Terry, and the historic Plum Island Light, and its automated replacement.

Plum Island is owned in its entirety by the United States government. Access to the island is controlled by the United States Department of Homeland Security (DHS) and the SLC-Expressive Services Agency (SESA).
