Despite its somewhat morbid appearance, giving seawater the distinct tinge of a deep blood-red, red tide is actually the result of something somewhat unexpected. When certain types of algae, called dinoflagellates, are present in high amounts, it causes what is known as an algal bloom. It’s important to note, however, that not all algal blooms will result in a red tide, as not all types of algae are red or brown in color, and oftentimes their concentration is not actually high enough to cause a change in the water’s appearance.

It also important to note that the title of “red tide” is not entirely accurate, especially as the phenomenon has nothing to do with the tides at all. Furthermore, harmful algal blooms can occur just as easily with dinoflagellates that are not red in color, and which in fact blend in so well with the natural coloring of the water that they are almost entirely undetectable. It is these algal blooms that are perhaps the most dangerous, because their presence is much less obvious while their affects can be just as disastrous.

But what makes algal blooms so dangerous? In terms of direct causes to the local wildlife, the affects can be quite deadly. Karenia brevis, the microorganism which is present in most Florida cases of red tide, produces brevotoxins that are highly poisonous to marine life. These toxins build up in seagrass and sediment, which is then fed on by primary consumers and eventually eaten by predators, negatively affecting and killing wildlife at all stages of the food chain.

While it’s not uncommon for red tide and other algal blooms to kill off large populations of fish and manatees, these harmful affects reach human beings in the area as well. Economically, the affects on marine life cause disruptions to fisheries and local restaurants, as animals containing brevotoxins are unsafe for human consumption. Furthermore, fishermen, beachgoers, and boaters can be affected simply through air exposure, as certain algal blooms can cause eye irritation and respiratory problems, especially in those with respiratory conditions already present.

Fortunately, no major red tides have occurred in South Florida during the 2015 season, and the coastlines and estuaries of the Everglades can easily be enjoyed on an exciting airboat tour. To view the Everglades ecosystem at its best, schedule a Florida swampland tour that the whole family can enjoy today.

After 3000 BCE, the water table was strong enough in South Florida to support numerous cultures throughout the state, one of which was the Glades people, so named for their proximity to the Everglades. The Glades people encompassed two separate tribes, the Calusa and the Tequesta, though people are much more familiar with the Calusa tribe today. While the Calusa Native Americans were not the only tribe to originally inhabit the area that is today known as South Florida and the Everglades, they proved to be the most powerful, controlling over fifty villages throughout the state and with numbers estimated around 7,000 at their prime.

The Everglades were central to life in the villages of Calusa Native Americans, with many villages located right on the mouths of rivers or on islands in the Florida Keys. And because water was so central to their lives, the Calusa utilized canoes as a means of traveling, often traveling as far as Cuba in their vessels. The Calusa, as well as other South Florida tribes at the time, could often be seen canoeing through the Everglades, as alligators, turtles, shellfish, and small mammals were an integral part of their diet. Much of the wildlife and plantlife in the Everglades proved integral to the lifestyle of the Calusa Native Americans, as many of their tools were fashioned out of reeds or the teeth and bones of their kills.

Unfortunately, like most Native American tribes in the Americas at the time, the Calusa could not hold up against the forces of European expansion. Some were killed outright, most died of illness, and by the start of the 1700′s, they numbered less than 1,000 in total. By this time they had been secluded to the Florida Keys, where they found refuge. Meanwhile, the Tequesta tribe, which were located in more of the Miami area on the east coast of Florida, faced similar problems and had their numbers drastically reduced. Eventually, what was left of the Tequesta merged with what was left of the Calusa, and by around 1820 or so, all Native Americans at the time in South Florida were grouped into a single term, “Seminoles.”

The Seminoles were friendly with the Spanish and were often referred to as “Spanish Indians” by the locals, and they also acted as allies with fugitive black slaves who found their way to Florida. During the Seminole Wars of the 1800′s, the Native Americans fought against U.S. troops who were attempting to speed up the annexing of the state into the union. When there were only a few hundred Seminoles left, the U.S. decided to leave them alone, and the culture still remains alive today as the Seminole Tribe of Florida, established in 1957.

While the Florida Everglades do look drastically different than the area appeared even a few hundred years ago, and further different still then the area appeared during the time when tribes like the Calusa were in their prime, there is much natural beauty to be found here. To truly get deep into the Everglades to view areas not accessible to humans by foot, one should take an Everglades tour by airboat, an experience designed for the whole family to enjoy. Airboat rides are fast, thrilling, and safe, and are the only way to travel in the Everglades today.

Many non-native species in Florida and other parts of the world have become so commonplace and blend in so well with the natural ecosystem, that many natives to the area don’t even realize they are in the presence of relative newcomers. Others make their presence known fiercely, eradicating those who stand in their path and causing horrific and permanent impacts to the original ecosystem. While scientists can attempt to predict the results of such introductions and avoid any negative consequences, nature is at heart unpredictable.

Though no one can predict the results of introducing non-native species to new environments, it is the result of human involvement in nearly all instances. There are generally five major reasons why non-native species are introduced intentionally:

1. To make money – Most commonly, the introduction of non-native species has economic motivations. Fish have been introduced as sources of food, mammals as sources of fur, and even trees as sources of lumber.
2. To remind people of home – Though not so much the case in present day, in the past some species were brought along with immigrants as they started lives in new places. Though the intentions were often innocent, the effects could be detrimental.
3. To look nice – Sometimes species are brought to new places for reasons as simple as their aesthetic appeal. This is more often the case with plants, which are sometimes transported for decorative purposes.
4. To provide sport – This is more often the case with fish, for example, when brown trout were brought over to America from England. In some instances, the introduction of a single non-native species can bring both financial and recreational gains.
5. To solve problems – In modern times, this is why invasive species are most commonly introduced – with good intentions and to solve a current economic or ecologic problem. For instance, one such invasive species that poses a particular threat in South Florida, the cane toad, was initially introduced to control sugar cane beetle populations that were decimating crops.

It’s important to remember that while you can pinpoint various reasons for intentional release of non-native species, not all instances involve intentional release. Furthermore, because the original source can be so difficult to pinpoint, it can be difficult to truly know whether release was accidental or not. A good example is the Burmese python, another invasive species that can be found throughout the Everglades. While there is much speculation, it is actually unclear whether the Burmese python explosion in South Florida was the result of the snakes finding their way onto ships headed from Asia to Miami or simply the result of locals releasing their unwanted pets into the wild.

Fortunately, the Florida Everglades has many beautiful and unique native species that still call the area “home.” These include American alligators, flamingoes, and the Florida panther, just to name a few. To view any of these magnificent animals in their natural habitats, as well as possibly one or two species that don’t belong, take an airboat ride through the Everglades with Captain Mitch. Florida swampland tours were meant to be enjoyed by the entire family, and offer plenty of educational opportunities as well as entertainment.

John Ashley, who also occasionally went by the nickname of “Swamp Bandit,” was a bank robber, bootlegger, occasional pirate, and overall American outlaw, who was raised in the backwoods of the Caloosahatchee River near what is today considered Fort Myers. His father was a railroad worker and otter trapper who made a living out of fishing and hunting, and John followed in his footsteps, becoming a skilled trapper and alligator hunter by a very young age.

John Ashley’s first reported crime was the suspected murder of fellow otter trapper Desoto Tiger in 1911, though due to the intervention of one of his brothers, authorities were unable to arrest him for the crime. Afterwards, John spent a few years on the run in nearby states with his brothers, eventually forming a gang with his brothers and other outlaws they had met in their travels. This gang of robbers and murderers were estimated to have collected more than $1 million from over forty banks in the southern United States during the time that they were active, and became known simply as the Ashley Gang.

Prior to an arrest in 1915 during an attempted break-out for one of his jailed brothers, John began a relationship with Laura Upthegrove. Laura immediately took an active role in the gang, marrying John and acting as both a look-out and getaway driver during robberies, and earning herself the nickname of “Queen of the Everglades.” During John’s incarceration, the Ashley Gang remained active in South Florida, even adding moonshining and rum running to their repertoire, and Laura took on a central role in the business during John’s absence, keeping her role even after his death.

Though a skilled criminal, eventually able to escape from prison after only a few short years, John’s thirst for revenge turned out to be his downfall. Through the course of his legal troubles, John developed a feud with a local authority, Sheriff Baker, a feud which lasted for thirteen years. After remaining safe in California for a couple of years, John returned to Florida in 1924 to make an attempt on the Sheriff’s life. Things took a turn for the worse when the Sheriff received an anonymous tip on John’s location, and an intense police shoot-out ensued. John and three of his gang partners were killed in the event.

During his time as an outlaw, John Ashley became somewhat of a hero among the poor Florida “crackers” in the area. While his name might not be as well known as other gangsters from his era, at one point in time he and his gang were believed to be responsible for every major crime that happened in the state of Florida, and one state official even referred to John and his gang as the greatest threat to Florida “since the Seminole wars.” One thing is for sure, the so-called “King of the Everglades” certainly made his mark on South Florida’s history, and will never be forgotten.

To see some of the Everglades mangrove forests once utilized by John and his gang for hiding, take the family on an Everglades swamp tour. Many of these areas can only be accessed and experienced by boat, and an airboat ride is the perfect way to get up close and personal while safely enjoying some of Florida’s history.
