Crystal River, Florida

JPG --Picture of Dolphins. Chassahowitzka is one of more than 500 refuges in the National Wildlife Refuge System administered by the U.S. Fish and Wildlife Service. The National Wildlife Refuge System is a network of lands and waters managed specifically for the protection of wildlife and wildlife habitat and represents the most comprehensive wildlife resource management program in the world.

Located about 65 miles north of St. Petersburg, the Chassahowitzka National Wildlife Refuge is comprised of over 31,000 acres of saltwater bays, estuaries and brackish marshes with a fringe of hardwood swamps along the eastern boundary. The northern boundary parallels and includes some of the Homosassa River. The refuge extends southward across the scenic Chassahowitzka River for 12 miles to its southern boundary at Raccoon point.

The refuge was established in 1943 primarily to benefit waterfowl in an area long famous as a wintering area for ducks and coots. Today, although waterfowl numbers in south Florida have declined, the refuge has become increasingly important for the endangered West Indian manatees which utilize many of the refuge's tidal bays, creeks and rivers.

Chassahowitzka is unspoiled estuarine habitat along Florida's west coast that serves as important breeding and feeding ground for marine life. Shallow bays support an abundant growth of muskgrass which provides food for various birds and the endangered manatee.

Inland from the bays are the brackish creeks and ponds where widgeongrass, watermilfoil and other foods grow in abundance. The eastern boundary provides a few thousand acres of swamp habitat where oaks, cypress and red cedar grow. The outer islands consist mainly of red and black mangrove which provides habitat for colonial birds.

Many species of birds, including cormorants, great blue herons, green-backed herons, ospreys, white pelicans, and various species of waterfowl and songbirds are observed on the refuge.

Other animals inhabiting the refuge include numerous alligators and raccoons. River otters are seen occasionally exhibiting their aquatic skills. Deer, turkey, black bear, and predators such as the bobcat are occasional residents of the refuge.

Endangered and threatened species including nesting bald eagles, West Indian manatees, woodstorks, green sea turtles, Eastern indigo snakes and an occasional peregrine falcon are observed on the refuge.

The refuge provides a place for approximately 250 species of birds, over 50 species of reptiles and amphibians and at least 25 different species of mammals. Because of this, visitors are likely to see a variety of animals during a journey through the refuge.

Management objectives are oriented toward preserving and protecting the land and wildlife resources on the refuge. This requires an active law enforcement program designed to prevent disturbance of wildlife populations and the destruction of habitat.

The entire state of Florida is a fire ecosystem that has historically burned every three to ten years. Prescribed fire is used on the refuge to mimic the natural fire regime. This improves habitat and food availability for several wildlife species including endangered and threatened species.

76% of the refuge is a designated Wilderness Area meaning land that will remain uninhabited and preserved in its' natural state.

Visiting the Refuge

The refuge is only accessible by boat. Public boat ramps in the area of the refuge are limited, so visitors are advised to consult the enclosed map for the boat ramp access.

Because of the need to protect refuge lands and wildlife resources, special regulations have been enacted. These regulations concern public access and use of the refuge.

Units of the National Wildlife Refuge system stretch across the United States from northern Alaska to the Florida Keys, and include small islands in the Caribbean and South Pacific. The character of the refuges is as diverse as the nation itself.

The Service also manages National Fish Hatcheries, and provides Federal leadership in habitat protection, fish and wildlife research, technical assistance, and the conservation and protection of migratory birds, certain marine mammals, and threatened and endangered species.
