Governing body	U.S. Fish and Wildlife Service

Key West National Wildlife Refuge is a protected area in the Florida Keys archipelago administered by the U.S. Fish and Wildlife Service and located near Key West, Florida City and the southern tip of the Florida Peninsula. The refuge preserves tropical hardwood hammock, mangrove swamp and shallow marine habitats that support resident and migratory species associated with the Gulf of Mexico, Straits of Florida, Caribbean Sea and broader Atlantic Ocean ecosystem. It is part of a network of refuges, including Great White Heron National Wildlife Refuge and National Key Deer Refuge, that conserve biodiversity across Monroe County, Everglades National Park and the Florida Reef Tract.

Overview

The refuge was established to protect roosting, nesting and foraging habitat for seabirds and wading birds in the southernmost United States, and it functions as a component of regional conservation efforts tied to the Migratory Bird Treaty Act, Endangered Species Act, and federal conservation initiatives led by the U.S. Fish and Wildlife Service. It encompasses upland islands such as Boca Chica Key, Key West National Wildlife Refuge (island complex), and submerged lands adjacent to features like Sand Key and Dry Tortugas National Park waters. Managers coordinate with entities such as the Florida Fish and Wildlife Conservation Commission, National Oceanic and Atmospheric Administration, United States Geological Survey, The Nature Conservancy, and academic institutions including the University of Florida and Florida International University.

History

Origins of refuge protection trace to early 20th-century conservation moves influenced by figures and policies tied to migratory bird protection and the work of naturalists associated with institutions like the Smithsonian Institution and the American Ornithologists' Union. Throughout the 20th century the refuge’s boundaries and management mission evolved in response to pressures exemplified by events at Key West Harbor, military activities during World War II, and tourism growth linked to U.S. Route 1 and Overseas Highway. Restoration and policy adjustments involved partnerships with federal agencies such as the National Park Service and civic actors from Monroe County and City of Key West governance, as well as conservation organizations including Audubon Society chapters and international agreements like the Convention on International Trade in Endangered Species of Wild Fauna and Flora.

Geography and Habitat

Situated within the subtropical climate zone influenced by the Gulf Stream, the refuge includes low-lying islands, mangrove forests dominated by species found across the Florida Keys National Marine Sanctuary and seagrass beds contiguous with the Florida Reef Tract. Habitats include red, black and white mangrove stands, tropical hardwood hammocks similar to those in Biscayne National Park, tidal flats used by shorebirds along migratory routes to Central America and South America, and coral rubble near reef systems associated with Dry Tortugas National Park. The landscape links with marine corridors used by species moving between the Caribbean Sea, the Gulf of Mexico and the Atlantic Ocean, and is affected by hydrology patterns connected to Lake Okeechobee via regional oceanographic processes.

Wildlife and Conservation

The refuge supports nesting colonies of seabirds and waders such as brown pelican, great blue heron, tricolored heron, little blue heron, snowy egret, great egret, black-crowned night heron, and populations of terns and gulls that traverse routes to Bahamas and Cuba. It provides habitat for threatened and endangered taxa protected under the Endangered Species Act including the West Indian manatee, the green sea turtle, the hawksbill sea turtle, and species of shorebirds that link to international flyways monitored by the Migratory Bird Treaty Act programs. Fish and invertebrate communities in seagrass beds sustain commercially and recreationally important species such as spiny lobster, snapper, and grouper which are managed under federal statutes by NOAA Fisheries. Conservation actions include invasive species control coordinated with Florida Department of Environmental Protection, habitat restoration informed by research from the Smithsonian Tropical Research Institute and monitoring using techniques established by the North American Bird Conservation Initiative.

Recreation and Management

Public access is limited to reduce disturbance to nesting colonies; allowed activities adhere to rules administered by the U.S. Fish and Wildlife Service and are coordinated with law enforcement agencies including the U.S. Coast Guard and local Monroe County Sheriff resources. Managed uses include wildlife viewing, photography, scientific research permits granted to institutions like Florida Atlantic University and regulated fishing that aligns with management plans from Florida Fish and Wildlife Conservation Commission and NOAA Fisheries. Outreach and education partnerships feature organizations such as Audubon Society of the Everglades, local visitor bureaus in Key West, and cooperative stewardship initiatives with the National Park Service and The Nature Conservancy to balance recreation with conservation.

Threats and Climate Change impacts

The refuge faces threats from sea level rise driven by global greenhouse gas emissions as addressed in reports by the Intergovernmental Panel on Climate Change, increased storm intensity associated with Hurricane Andrew-scale events and recent major hurricanes affecting the Florida Keys, coastal development pressures from Monroe County land use trends, and invasive species introductions documented by the Florida Invasive Species Council. Climate-driven changes in ocean temperature and acidification documented by NOAA affect coral reef resilience across the Florida Reef Tract and alter food web dynamics impacting seabird and marine mammal prey availability such as that identified in studies by the National Oceanic and Atmospheric Administration and United States Geological Survey. Management responses integrate climate adaptation planning from federal guidelines, habitat migration corridors envisioned in regional conservation blueprints developed with The Nature Conservancy and resilience recommendations from academic research at University of Miami and Florida International University.
