How An Exotic Invasion In The Everglades Has Its Fans Worried

By Ashley Pontius

Burmese pythons and their battles with alligators get the headlines, but those large reptiles that came from Southeast Asia as part of the exotic-pet trade aren’t the only invasive species wreaking havoc on the Florida Everglades.

The National Park Service reports that the Everglades are suffering from a barrage of pressure brought on by numerous nonnative species, including exotic fish that gobble up native fish species and melaleuca trees that crowd out indigenous plants.

Now the pressure on the fragile ecosystem in south Florida could get even worse. Just recently, the Trump administration said it was disbanding the Interior Department’s Invasive Species Advisory Committee, which had coordinated the federal government’s efforts at controlling pythons and other invasive species plaguing the nation.

That has fans and defenders of the Everglades concerned.

“The Everglades have faced a number of threats over the years, and certainly one of the very serious ones has been invasive species,” says Clyde Butcher (www.clydebutcher.com), a nature photographer who since the 1980s has helped bring national awareness to the Everglades through stunning black-and-white photographs that have been compared to the works of Ansel Adams.

Butcher and his photography have been witness to some of the changes invasive species have wrought. He notes that one of his early photographs taken in 1986 along the Tamiami Trail provides an example of the delicate balance in the Everglades. A thick cloud formation and a dark sky initially draw a viewer’s attention, but Butcher points to the grassy plains in the foreground.

“Most of the grass in that picture was sawgrass, which later was overcome by invasive exotic plants,” Butcher says.

He says many people going about their daily lives, even in south Florida, are unaware of what would be lost if more isn’t done to protect this unique natural wonder from invasive species and other environmental hazards.

“With my photography, I’m trying to educate people that the environment is really important, and they need to actually experience it themselves,” Butcher says. “Looking at photographs in a gallery where you have air conditioning and there are no bugs is nice, but there’s nothing like experiencing the real thing.”

A few of the reasons that invasive species are a concern to Butcher and other defenders of the Everglades include:

Lack of natural predators. Because nonnative species typically lack natural predators, they can outcompete native species, the National Park Service reports. They can multiply unchecked, using up valuable resources such as sunlight, water, and nutrients. Native species suffer from this intense competition.

Severe decline of mammal population. Those Burmese pythons aren’t just wrestling with alligators. They also make meals out of mammals that call the Everglades home, which is one reason the state sponsors hunting contests among other efforts to get rid of them. Since the late 1990s, the Everglades have seen a steep decline in populations of raccoons, opossums, and bobcats, the U.S. Geological Survey reported. Marsh rabbits, cottontail rabbits, and foxes effectively disappeared.

Economic impact. Infestations of invasive plants and animals can negatively affect property values, agricultural productivity, public utility operations, native fisheries, tourism, and outdoor recreation, according to the U.S. Fish and Wildlife Service. In a state like Florida, where agriculture and tourism are major industries, that’s significant.

Butcher says walking through the Everglades can be a spiritual experience, one he would like to see as many people as possible share.

“For me, the inspiration has been overwhelming to try to record this for people, for posterity, because it’s so unique in the world. I’m not sure there’s another place like it.” said Clyde.

Award-winning photographer and National Geographic Explorer T homas P. Peschak will receive the National Geographic Society’s 2025 Eliza Scidmore Award for Outstanding Storytelling for his long legacy of conservation storytelling at National Geographic and beyond.

The award — named for the writer and photographer Eliza Scidmore, the first woman elected to the Society’s Board of Trustees in 1892 — recognizes individuals whose work focuses on immersive storytelling to advance our understanding of the environmental and conservation issues we face, with the ultimate goal of supporting societies in making the best decisions for a healthier planet.

While Peschak began his career training as a marine biologist specializing in human-wildlife interactions, he eventually moved to photojournalism after realizing his impact on conservation could be greater through storytelling to inspire change. Now, Peschak’s accomplishments are world-renowned, with 18 Wildlife Photographer of the Year wins, seven World Press Photo Awards, and most recently, the 2024 Wildlife Photojournalist Story Award — all for his significant work documenting some of the most crucial conservation stories of our time.

“Tom’s work is rooted in a commitment to drive meaningful impact. Whether documenting vital ecosystems, the plight of at-risk species or the stories of communities, his images open our eyes to the world, make it clear what’s at stake and inspire us to act,” said Jill Tiefenthaler, CEO of the National Geographic Society. “Tom’s dedication to illuminating and protecting the wonder of our world defines his work, and it’s why we are deeply honored to present him with the 2025 Eliza Scidmore Award for Outstanding Storytelling.”

Most recently, he was the lead storyteller on the National Geographic and Rolex Perpetual Planet Amazon Expedition, a multiyear series of solutions-centered science expeditions spanning the entire Amazon River Basin. Working with fellow Explorers and local communities, Peschak immersed himself in the basin for 396 days to reveal its aquatic and wetland habitats. The single-topic October issue of the National Geographic magazine was devoted entirely to Peschak’s stunning images of the Amazon Expedition. Starting with ice axes and crampons in the icy high Andes and finishing with scuba gear in the Atlantic Ocean, he created the first-of-its-kind comprehensive photographic archive of our planet’s most iconic and biodiverse river system.

To date, Peschak has photographed 20 National Geographic magazine features on various subjects, including manta rays, sea turtles, climate change in Antarctica and the global seabird crisis, the latter of which resulted from a Society grant in 2017. Seeking to address the loss of 230 million seabirds over 60 years, Peschak mined archives for images of seabird colonies in Peru taken 100 years ago and re-photographed those same locations, presenting these images side by side in an innovative multimedia display to visualize this staggering absence in the hopes of protecting this ecologically critical and unique species.

In addition to his extraordinary photojournalistic work, Peschak has written and photographed eight books, including “Sharks and People,” which chronicles the relationship between people and sharks around the world, and “Wild Seas,” a collection of photos taken by Peschak documenting the beauty and fragility of underwater life and wild coastlines from around the world. He has also appeared as a speaker for the National Geographic Live! series, having presented over 20 shows in 15 cities on three continents.

“Photography and storytelling aren’t just about highlighting places with unique biodiversity, especially when areas like the Amazon basin are under siege every day from issues like overfishing, pollution and climate change,” said Peschak. “To capture the full scale, it’s imperative to highlight these challenges as well as the people who are facing them head-on: local communities, Indigenous peoples, researchers and other Explorers. The goal and hope with my work has always been to photograph places I love in order to help save them, so it is a true honor to receive this award and get to continue to work on important stories of conservation.”

While remaining a cornerstone of storytelling work at the Society, Peschak continues to focus on marine conservation storytelling more broadly, serving as the director of storytelling for the Save our Seas Foundation — an organization he has been an integral part of for almost two decades. He is also a founding director of the Manta Trust and a senior fellow of the International League of Conservation Photographers.

Peschak will be honoured as the 2025 Eliza Scidmore Award recipient during the annual National Geographic Society Storytellers Summit in February 2025. To learn more about Peschak and other Explorers’ work, visit our website here.

Manta Ray Magic: Witnessing a Feeding Frenzy in the Great Barrier Reef – Photography by Aliya Siddiqi

While working at an island that’s known as “the home of the manta ray,” it’s easy for most of us staff to get jaded at seeing one or two manta rays…per day. Maybe they do a quick cruise past, or maybe a stop at the cleaning station. But when these mantas do aggregate around this small island on the Great Barrier Reef, those are the days that turn into pure magic. And it reminds us all as to why these animals are so spectacular to interact with.

Manta rays, more specifically Manta alfredi, are unique in the contrast between their large size and inquisitive behavior around humans. Despite reaching average lengths of three to five meters wingtip to wingtip, they are filter feeders and seek out the smallest creatures in the ocean to feed on. The diets of manta rays are found to consist mostly of different types of zooplankton, small creatures that range from microscopic single-celled organisms to the larvae of larger animals like crabs, octopuses, and fish. Zooplankton are heterotrophic, meaning that they obtain their energy from feeding on other organisms including phytoplankton and other zooplankton. In this photo series, all of those small dots sparkling in the photos indicate a high number of plankton.

According to scientists studying the island aggregation site, the higher biomass of zooplankton seems to be a result of “local concentration and retention processes around the island”. Though still unknown why these zooplankton blooms around the island happen, when it does become what we call “manta soup,” the foraging behaviour of the manta rays gives guests and staff some unforgettable experiences. The elasmobranchs ensure filter-feeding efficiency by looping around consistently in nutrient-dense areas. All one must do is stay in that same spot and wait for the mantas to swoop in and detour around you – though with strong currents, this is often more easily said than done. However, some days you get lucky when the weather window blesses you with no wind, high zooplankton biomass, and an influx of manta rays.

These photos come from a day like that, making it almost too easy for an amateur photographer like me to capture these charismatic animals. The mantas were swooping in and out, with some of the females displaying quite pregnant bellies. Like any aggregation site, tourism operators greatly benefit from the frequency at which these animals appear. Their docile and curious nature also makes them excellent flagship species for marine conservationists. Listed as Vulnerable to Extinction by the IUCN, these experiences with the public allow for an opportunity to discuss the challenges our oceans are facing, and why protection is of the utmost importance.

Cleaning Stations & Coastal Cruising – Under the Waves with Karim Iliya, October 2024

This is a turtle cleaning station. You can see the turtle in the back getting cleaned by a fish which eats parasites and algae off the turtle’s skin, shell, and scales. The turtle in the front is waiting its turn. This is a symbiotic relationship in which the turtles get cleaned, and the fish get a meal.

A Hawaiian green sea turtle cruises beneath the waves off the coast of Hawaii. This turtle was eating algae off the rocks, seemingly unaffected by the powerful turbulent water all around. When not eating algae, these turtles spend much of their time laying on the nearby beach .

Karim was published in National Geographic magazine for his humpback whale photography. He now leads his own trips so that others can swim with whales.

If you are interested in swimming with or photographing humpback whales, Karim guides people on small trips between August and October every year in Tonga. Visit www.dancewithwhales.com to find out more
