The Consequences of Invasive Species in the Florida Everglades

invasive speciesThe Florida Everglades have long been a popular tourist destination for visitors from around the United States and around the world. It is easy to see why so many people make this a must see place on their “bucket lists” since it is a unique, one of a kind landscape that gives you access to an incredibly diverse and sensitive environment. The Everglades is a wilderness preserve like no other, allowing visitors a chance to experience flora and fauna that can’t be seen many (if any) other place on earth.

However, there has been consequences from urbanization and tourism. As population has grown, the Everglades have been encroached upon more and more. Some of the swamps were drained to make way for residential, commercial, or industrial complexes as the nearby cities demanded more jobs and places to live. Now, thankfully, what remains of the Everglades is protected and kept as safe as possible from further encroachment or pollution.

It isn’t just people that have been trying to worm their way into the Everglades and snuff out the native species that once thrived there. Foreign plants and animals, often referred to as invasive species, pose, perhaps, an even graver threat to the health of the ecosystem than humans do, though they would never have been a problem had it not been for humans.

When we began to trade further and further from our own shores, with those goods we asked for, came things we didn’t. As trade expanded, new plants and animals that hitch rides across the sea via trade cargo boats, landed on the shores and began to take over, as they didn’t face the native predators in this new place that they did at home. Many of these species quickly took advantage of their new environment and spread rapidly and aggressively.

A lot of the native plants and animals are specialists, which means they require a pretty stable and exact ecosystem to thrive or even survive. As invasive species have made their way into sensitive areas like the Everglades, the native plants find their nutrients and food sources dwindling and can often not compete with the foreign invaders. It often doesn’t even take very long for these invaders to almost completely push out the native flora and fauna, leaving behind a very different landscape.

It is for this reason that there are such staunch rules about the importation of plants and animals from abroad. It is helpful to be cognizant of this problem if you plan to visit the Everglades and it is advised that you take steps, especially if you are visiting internationally, to ensure that you do not bring any potentially harmful spores, seeds, or bugs to the sensitive landscape.

Seasons of the Everglades

seasonsThe rest of us may have four seasons (Spring, Summer, Fall, and Winter), but did you know the Everglades only has two seasons? The Everglades seasons don’t go by the temperature, but rather the water levels in the wetland. The two seasons are known as: the Wet Season and the Dry Season.

The Everglades’ wet seasons runs from April to November. During this time, the area experience intense storms and rains. The Everglades gets about 60 inches of rain per year. The Dry Season begins in November and ends in April. There is little rain during the dry season, usually only around a quarter of the yearly rainfall occurs during the dry season.

The Everglades’ water levels aren’t just determined by the rainfall in the Everglades, but in other parts of the state of Florida, as well. Why? Well, there are so many different bodies of water that flow into the Everglades. Rain in Central Florida makes its way down into Lake Okeechobee and Florida Bay, which lead into the Everglades.

Since humans have disrupted the natural flow of water in the Everglades (water has been diverted), animal and plant life populations have changed and declined. Naturally, the water levels in the Everglades change month to month, but the animal life and plant life that are native to the area are accustomed to these water changes. In fact, they expect and depend on the water levels to change.

For example, some birds will only nest if the water level is at a certain height; if it’s not, the birds will be hesitant to settle down to nest. There are many reasons birds fly to the Everglades during the winter.  Since it’s the dry season in Florida, it’s not only warmer than the North, but the dry weather makes it easier for the birds and their offspring to find food. Birds, like the Wood Stork and Anhinga breed, need shallow water to find fish and other food sources faster and easier. When the water levels change, the birds will start to look for other places to nest or won’t breed at all.

The ecosystem of the Everglades is delicate. It requires an ideal balance for the animals and plants to be happy and thrive. Unfortunately, humans, storms, climate change, and invasive species can wreak havoc on this balance. If there is too little or too much water in the Everglades, animals will move elsewhere, plants will die off and slowly more and more negative changes will begin to snowball. This water affects breeding, drinking, growing, and provides homes and shelters.

The water in the Everglades even affects humans’ drinking water. As water flows into the Everglades, it gets soaked into the limestone underground and gets stored into aquifers (caves). Aquifers are fresh water sources. The Biscayne Aquifer provides the clean drinking water for southeast Florida.

A proper balance of water is essential in the Everglades, as well as the water’s timing and quality and where it ends up.

Research in Everglades National Park

research in the evergladesThe Everglades National Park may be full of plants, animals, birds, insects, fish, and water, but it’s also home to many different research programs. The South Florida Natural Resources Center (SFNRC) conducts research that informs the management of the south Florida parks pertaining to wildlife, restoration, water quality, hydrology, and invasive plants and animals.

Here is a list of some of the research groups, monitoring programs, natural resources management and restoration assessments going on in the Park.

  • Ridge and Slough Ecology Program
  • Ecological Modeling Program
  • Hydrologic Modeling Program
  • Hydrologic Monitoring Program
  • Wildlife Monitoring Program
  • Aquatics Program
  • Invasive Plant Program
  • Invasive Animal Program
  • Marine and Estuarine Resources Management
  • Modified Water Deliveries Project
  • Comprehensive Everglades Restoration Plan Project
  • Tamiami Trail Next Steps Project

Below, we wanted to share a little more detail about what a few of these programs do, so you can have a little insight into the science, research, and work happening in the Everglades.

  • Wildlife Monitoring Program – This program has been around for quite some time and has been able to gather information critical to the management of wading birds, sea turtles, alligators, eagles, Florida panthers, and more.
  • Aquatics Program – In this program, freshwater fish and invertebrates are monitored to track for season and long-term changes due to natural weather patterns and water management.
  • Modified Water Deliveries Project – This project began in 1992 and is almost completer; this project will allow an incremental increase in water flow into the Northeast Shark River Slough. With the increased water flow and quality, the habitat is expected to improve, which would bring more species back to the area.
  • Marine and Estuarine Resources Management – In this program, marine habitats and organisms are monitored to track gamefish populations based on what fisherman are catching. They also monitor fish populations (in general) and their habitats.

The Everglades’ Old Ingraham Highway

One of the oldest and most historic roads in the Everglades is Old Ingraham Highway.  Work began on this road in 1916 and it was completed in 1922. The road was named after James E. Ingraham, who was the president of the Model Land Company and vice president of the Florida East Coast Railroad. Since this road goes through Royal State park and Florida East Coast Railroad helped making Royal Palm a State Park, it made sense the road was named after Ingraham.

This road was created to be a way to access the Flamingo area. People would drive their vehicles down to visit areas along Florida Bay. It was built on piles of limestone. The old road still exists from the Anhinga Trail to Snake Night. This road is no longer open to cars or bikes, and is considered a wilderness area.

If you’re looking to hike this road, please note there is little shade and it is around 10 miles, 20 miles round trip. Wear sunglasses, hats, and apply sunscreen. This takes around 5 hours to complete, one way. This is an easy to navigate path. The pavement has disintegrated, and the road is mostly gravel or potholes these days. Since it is a wilderness area, the trail isn’t maintained like some other trails in the Park. Be aware there could be a few plants or branches that you may have dodge.  You will come across mangroves and sawgrass, along with endless other plants.

Along the trail, there is a canal where birds and alligators can be spotted, especially during the dry season. The trail is open year-round.  There are also entrances to old campsites on the trail, but they are no longer in use.

Walking around the Everglades is a truly magical experience; however, it can also be extremely hot, tiring, and buggy. If you’d like a cooler, less exhaustive and equally-as-fun way to get around the Everglades, jump on an airboat tour with Captain Mitch’s Airboat Tours. Captain Mitch has been people around around the Everglades for decades. To book an airboat tour, click here or call 800-368-0065.
