Everglades National Park
A River of Grass
Everglades National Park has is a “River of Grass” (or a swamp by others). It is really a long, shallow river nearly 50 miles wide and more than 100 miles long. The dominant life form in the “river” is periphyton, a mossy golden-brown substance found floating in the water. Periphyton is a complex mixture of algae, cyanobacteria, heterotrophic microbes, and detritus. It attaches to submerged surfaces in an ecosystem also serving as an important food source for invertebrates, tadpoles, and some fish.
Sawgrass marsh makes up about 70 percent of the Everglades. In the northern Everglades it is tall and dense, making some areas of water barely visible. In the south it tends to be short and less dense. Sawgrass has serrated, razor sharp blades that can cut through clothing.
Everglades National Park is much smaller today than in years past. Construction and drainage projects are a factor in the reduction of around 50% of the wetlands. thus, the restoration of the Everglades has been an issue for many political debates in Florida. Both state and federal governments are working to restore and protect the Everglades.
The Past
Calusa (kah LOOS ah) Indians lived on and controlled most of the southwest coast of Florida. The Everglades were central to life in the Calusa Indian villages. Many were located on the mouths of rivers above the Everglades. The natives traveled by canoes through the Everglades to hunt alligators, turtles, shellfish and small mammals that were essential to their food supply. The teeth and bones of wildlife and reeds from the plants in the Everglades were used for making tools. The Native Americans called the area “Pahayokee (pay-HIGH-oh-geh), meaning “grassy waters”. The Calusa declined with European expansion to the area. Some were killed, but most died of diseases brought in by the European settlers.
Everglades National Park Weather
There are two seasons in the Everglades: wet and dry. This results in the area alternating with seasons of flood and drought.
The wet (summer) season accounts for around 80% of the average annual rainfall in the area (50+ inches) and lasts from May through November. The humidity and temperatures (90+F) during this time are high. Most afternoons have thunderstorms (and occasional hurricanes). The rainy season is important in renewing the fresh-water supply. Hurricanes can be good for the ecosystem because they make new areas for plant growth. Seeds also scatter, and storms cause water movement in the normally shallow, slow moving river. Recent hurricanes have impacted the Everglades (Katrina, Rita, and Wilma, Irma).
Rainfall is the primary method water enters the Everglades. Evapotranspiration accounts for 70-90% of the rainfall leaving the area.
The dry (winter) season begins in December and goes through the month of April. It brings cooler temperatures (55F-77F) and little rain. The dry season is especially important for the reproduction of the birds and wildlife in the area.
Fire
The dry season causes drought conditions that are perfect for fires. The Florida Everglades have recently experienced fires around the Big Cypress National Preserve. Although fire may seem to be a destructive element to nature, most often it is not. Fire is essential for maintenance and also new growth of the land.
Environmental factors are always changing the ecological system. The climate and frequency of rain, storms, and fire all change the Everglades on a continual basis.
Everglades Water Supply
Approximately one third of people living in Florida rely on water from the Everglades for their fresh water supply. This makes protecting the Everglades extremely important.
Plant Life in Everglades National Park
Wet sawgrass prairies and periphyton are plentiful in the Everglades. The river holds mangrove and cypress swamps, pinelands and hardwood hammocks. Hammocks are dry land that rise out of the grassy river. Tropical and subtropical trees such as the southern live oak grow on them.
The oldest and tallest trees in the Everglades are cypresses. They have roots especially adapted to grow underwater. Big Cypress Swamp is well known for its 500 year old cypresses.

Wildlife in Everglades National Park
Everglades National Park is home to at least 350 species of birds, 50 reptile species, 300 species of saltwater and freshwater fish, and 40 species of mammals. In addition, the ecosystem provides protection for 14 endangered and nine threatened species, including the Florida panther, the Atlantic Ridley turtle, the leatherback turtle, the West Indian manatee, the snail kite, the Cape Sable seaside sparrow, and the American crocodile. There are at least 36 species that live in Everglades National Park that are on the protected, threatened, or endangered list.
The Everglades are a refuge for large wading birds, such as the wood stork, great blue heron, egrets, and the roseate spoonbill and it is the most important tropical wading bird breeding ground in North America.
This area is the only place in the world where alligators and crocodiles co-exist together in the wild. Crocodiles are in small numbers in the coastal areas of the Everglades. On the other hand, alligators stay more inland, near the freshwater.
Even mosquitoes play an important role to the Everglades. The larvae of grown mosquitoes are food for fish. Then, the larvae become an important food source to the diets of the wading birds.
Pythons have become an invasive species to the area. Recently, professional trained python bounty hunters are helping to help remove these large snakes from the area because they pose a threat to the ecosystem food source.
Visitors to Everglades National Park
More than one million people from all over the world visit The Florida Everglades every year. It is the third biggest national park in America. Only Yellowstone and Death Valley are greater in land mass. Everglades National Park provides a fantastic learning experience to those of all ages and is also a great family adventure. Photographers find the landscape and the wildlife the perfect setting for great photos.
The busy visitor season is from December through March because it is the driest time of the year. The temperatures are also cooler, and there are fewer mosquitoes.
If you are considering a trip to the Everglades, be sure to bring along water and an insect repellant. Protective clothing may also be necessary depending on what you are doing or where you are going.

We highly recommend a day trip to Everglades National Park to our guests at Sea Mar Condo https://seamarcondo.com. The park is only a short 45 minute drive from the condo and is a great day adventure. On one of our recent trips there we saw almost 30 alligators and many wading birds (including a roseate spoonbill).
