Manatees gather in the Banana Creek inside NASA's Kennedy Space Center. Manatees live in Florida's warm-water rivers and inland springs. The Florida manatee feeds on more than 60 varieties of grasses and plants. Manatee cows give birth about once every three years. Gestation lasts about 12 months. KSC shares a boundary with the Merritt Island National Wildlife Refuge, which encompasses 92,000 acres that are a habitat for more than 331 species of birds, 31 mammals, 117 fishes, and 65 amphibians and reptiles.

The Merritt Island refuge also includes several wading bird rookeries, many osprey nests, up to 400 manatees during the spring, and approximately 2,500 Florida scrub jays. It also is a major wintering area for migratory birds. More than 500 species of wildlife inhabit the refuge, with 15 considered federally threatened or endangered. Photo credit: NASA/Kim Shiflett

Two manatees swim leisurely in waters on Kennedy Space Center. They gather in Florida's warm water rivers and inland springs during the winter. KSC shares a boundary with the Merritt Island National Wildlife Refuge, which encompasses 92,000 acres that are a habitat for more than 331 species of birds, 31 mammals, 117 fishes, and 65 amphibians and reptiles. The marshes and open water of the refuge provide wintering areas for 23 species of migratory waterfowl, as well as a year-round home for great blue herons, great egrets, wood storks, cormorants, brown pelicans and other species of marsh and shore birds, as well as a variety of insects

CAPE CANAVERAL, Fla. – A manatee swims in the Banana River during a field-guided boat tour of NASA's Kennedy Space Center in Florida. As part of the center's first-ever Innovation Expo, the tour, called "Living Outdoor Laboratory for Environmental Sustainability," is giving employees the opportunity to see the unique estuarine ecosystems that are protected from development by the presence of Kennedy and the Merritt Island National Wildlife Refuge. Manatees are one of the many threatened or endangered species that call the refuge home. The diverse and healthy area encompassing about 140,000 acres of central Florida's east coast has been closed to the public for 50 years, allowing the coastal dunes, saltwater estuaries and marshes, freshwater impoundments, scrub, pine flatwoods, and hardwood hammocks to provide habitats for more than 1,000 species of plants and animals. Innovation Expo is showcasing the innovative work taking place throughout the center's facilities and labs to encourage employees to work together to solve future challenges.

CAPE CANAVERAL, Fla. – Two manatees swim near the Banana River shoreline a few miles from the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. Kennedy is located on Merritt Island, a barrier island, about 34 miles long and varying in width from five to 10 miles. Only 6,000 acres are actually used for operational activities. The Kennedy Space Center is also a National Wildlife Refuge. Consisting of 140,000 acres, the refuge provides a wide variety of habitats: coastal dunes, saltwater estuaries and marshes, freshwater impoundments, scrub, pine flatwoods and hardwood hammocks providing habitat for more than 1,500 species of plants and animals.

KENNEDY SPACE CENTER, FLA. -- This adult bald eagle rests on the ground near a pond close to S.R. 3 in NASA's Kennedy Space Center. Bald eagles live near large bodies of open water such as lakes, marshes, seacoasts and rivers, where there are plenty of fish to eat and tall trees for nesting and roosting. Bald eagles feed primarily on fish, but also eat small animals (ducks, coots, muskrats, turtles, rabbits, snakes, etc.) and occasional carrion (dead animals). They are sometimes seen among a gathering of vultures at the site of a fresh meal. Bald eagles have a presence in every U. S. state except Hawaii. Bald eagles use a specific territory for nesting (they mate for life), winter feeding or a year-round residence. Its natural domain is from Alaska to Baja, California, and from Maine to Florida. There are a dozen eagle nests both in KSC and in the Merritt Island National Wildlife Refuge, which surrounds KSC.
