Sometimes we only appreciate something when we realize we may lose it. That is the story of the Everglades. A shallow slow-moving river, the Everglades once covered about 18,000 square miles of southern Florida. Until the 1900s, few people lived in the grassy wetlands. Not much was understood about the unique balance of nature that existed there. Plants, creatures, and water had formed a remarkable ecosystem. South Florida has two seasons—a dry season and a wet season. During the wet season from April to November, rain historically saturated the land. It also filled Lake Okeechobee in central Florida. When it rained a lot, the lake overf lowed its southern banks. It created sheet f low. Sheet f low is water f lowing in a thin layer over the landscape. In this…

first footsteps

An extraordinary odyssey began in the frozen terrain of Asia. It ended thousands of miles away and thousands of years later in the hot, grassy wetlands of Florida. The journey was made possible by the largest land bridge in history. Created by nature, the 1,000-mile-wide expanse of earth is known today as Beringia. It existed in the frigid waters between Russia and Alaska. Over different periods of time, the melting and refreezing of glaciers caused Earth’s water level to rise and fall. During the periods of lower water levels, the land was exposed. Beasts and humans moved across it. (Scientists believe some of the early nomads may have traveled by sea, too.) Although those Paleo-Indians probably arrived around 15,000 years ago, they were not the first living things to make the…

a range of habitats

The Everglades once covered millions of acres from central to southern Florida. Today, Everglades National Park encompasses a fraction of that original size—1.5 million acres. It still consists of a wide range of landscapes. Although the Everglades is mostly flat, slight changes in elevation create dramatically different vegetation types. Here’s a look at some of the unique habitats found there. Hammocks A hammock is a dense forest of trees and shrubs. The trees grow together on land that is slightly higher than the surrounding marshy and rockland areas. The elevated terrain protects hammocks from flooding. In some types of hammocks, acids from decaying plant matter dissolve the Everglades’ limestone base. That process creates a natural moat around a hammock “island” that protects it from fire. The humid surroundings and moist soil also…

the everglades

Today, Everglades National Park (OPPOSITE) preserves only a portion of the original Everglades. The historic Everglades once included wetlands that stretched from the Kissimmee River to Lake Okeechobee and southward to Florida Bay. BELOW RIGHT: The different types of habitats in the Everglades are re-created on this map. BELOW LEFT: A modern satellite image of the lower Florida peninsula captures darkened portions south of Lake Okeechobee as the Everglades and Big Cypress Swamp. The red area near the lake is an agricultural area.…

There are more than 40 native species of mammals in the Everglades, including bobcats, gray foxes, river otters, squirrels, opossums, bats, and mice. Finding the tracks of a Florida panther in the Everglades is exciting and rare. The big cats are not often seen. They roam the pinelands at night and stay out of sight. Among all the animals in the Everglades, the panther is the most endangered. There are only about 200 left, and their numbers are steadily decreasing. In the 19th century, a bounty was established allowing hunters to profit by capturing and killing the animals. Although the panther is at the top of the food chain, its shrinking habitat and the decreasing populations of small mammals to hunt contribute to its endangered status. Marsh rabbits once were among the…

man on a mission

Unlike other national parks in the United States, which preserve stunning scenery or remarkable geological features, Everglades National Park’s claim to fame is its biodiversity. Such a park became a reality largely thanks to the efforts of one man: Ernest F. “Tom” Coe. Coe was 60 years old when he and his wife, Anna, moved from New Haven, Connecticut, to Florida in 1925. Coe had a degree from Yale University’s School of Fine Arts. He had spent his life as a landscape architect designing gardens in New England. The chance to work with new types of plants and flowers in South Florida appealed to Coe. The Coes moved into a house in Coconut Grove, not far from Miami. Coe loved the outdoors. It didn’t take long for him to start exploring the…
