Annual challenge encourages the public to catch as many of the invasive giant snakes that decimate native wildlife as possible
Most visitors to the mosquito-infested swamps of the Florida Everglades are happy to leave again quickly: a half-hour airboat ride and photograph of a basking alligator is usually enough to satisfy the curiosity of any tourist keen to return to the theme parks and beaches – or sports events – of the sunshine state’s more traditional attractions.

Since we started this platform in 2011 I have been on the lookout for graphical representations that help me, and therefore might help others, understand complex issues related to the environment. Photography has been the easiest reach for me, perhaps because I am a son of, a brother of, and a father of people who have mastered that form. Comics were not part of my life, so that form has eluded me. And I realize that the work of Susie Cagle escaped my attention–as I have shared visual artists’ depictions of natural phenomena, with science and especially ecological issues emphasized–until now. And this is a good way for her work to come to my attention, because in our family we have been debating this tree’s value for decades:
The fight over a celebrated exotic plant highlights questions over California’s future amid the climate crisis
With invasive species, sometimes the only thing to do with such lemons is make them tasty:
Voracious purple urchins in waters of California and Oregon pose threat to kelp forests and risk upending delicate ecosystems
Tens of millions of voracious purple sea urchins that have already chomped their way through towering underwater kelp forests in California are spreading north to Oregon, sending the delicate marine ecosystem off the shore into such disarray that other critical species are starving to death.
A recent count found 350m purple sea urchins on one Oregon reef alone – more than a 10,000% increase since 2014. And in northern California, 90% of the giant bull kelp forests have been devoured by the urchins, perhaps never to return.
Vast “urchin barrens” – stretches of denuded seafloor dotted with nothing but hundreds of the spiny orbs – have spread to coastal Oregon, where kelp forests were once so thick it was impossible to navigate some areas by boat. Continue reading
There are tens of thousands of pythons in the Florida wild, attacking animals and damaging ecosystems – and the quest to stop them has become a collective crusade
On a Thursday afternoon in St Petersburg, Florida, Beth Koehler crouches over a cairn terrier named Ginger, trimming intently as fur collects around her feet. On Koehler’s arm is a scratch – red, jagged and freshly acquired, though not in the way one might expect of a dog groomer.
“There was no way I could pin the head,” Koehler says, referring to the snake that was partly responsible. She had grabbed hold however she could, which made it “pissed”: “It decided to coil up and just throw itself at me.” Startled, Koehler had fallen backwards, cutting herself on a vine – an injury far preferable to the bite of a Burmese python.
“I have never been bit,” she proudly adds. “Peggy’s been bit once, but really, we’re very careful.”
Three days a week, Koehler runs Hair of the Dog with her partner of 31 years, Peggy van Gorder. The other four days the couple are usually out chasing pythons as members of Patric: the Python Action Team – Removing Invasive Constrictors, which is managed by the Florida fish and wildlife conservation commission (FWC).

After writing about some of Cyprus’ environmentally destructive actions, it feels good to hear about these positive organized efforts to eradicate this marine threat. Lionfish have long been on our radar, but this is the first we’ve heard of their spread through European waters.
Perhaps a new venue for eradication idea exchange is in order!
Cyprus has held its first organised cull of lionfish after numbers of the invasive species have proliferated in recent years, threatening the Mediterranean ecosystem and posing a venomous danger to humans.
“They’re actually very placid,” said Prof Jason Hall-Spencer, a marine biologist, after spearing 16 of the exotic specimens in the space of 40 minutes in the inaugural “lionfish removal derby” off the island’s southern coast. He added: “The problem is they are not part of the natural ecosystem and we are seeing them in plague proportions.”
Lionfish, armed with venomous dorsal spines that enable them to deter predators, are more normally associated with warm tropical waters of the South Pacific and Indian Ocean. Almost two decades ago the non-native tropical fish began to enter US waters, appearing in the Atlantic after pet owners started releasing outsized lionfish from home aquariums into the sea. Now they have reached Europe. In 2012, after initial sightings off Turkey, Israel and Lebanon, they were spotted off Cyprus. Three years later they had appeared further south in Greece, Italy and Tunisia, testimony, scientists say, to their ability to both enter new territories and spawn at record rates.
As numbers proliferate, so have fears of the flamboyantly coloured fish posing the biggest ecological setback to ecosystems in the Mediterranean – which is already under pressure from pollution, tourism and over-exploitation. In the EU, Cyprus has become “the first line of defence” against the lionfish invasion. Continue reading
Elephant conservation has taken many forms over the years. When writing about the recent Real Elephant Collective collaboration exhibit that took place in Cochin a few months ago, I realized that art installations using elephants as symbols for big picture conservation have existed for some time.
Having been unable to attend the exhibit personally, Anoodha and the Curiouser team make me feel that I was there.
We missed the story last year about two men in the photo above, from southern India, who were brought to the Florida habitat where invasive pythons are doing enough damage that we started paying attention eight years ago. We are thinking about it again, thanks to the Guardian:
Snake hunters have captured what they say is the largest python ever found in the swamps of the Florida Everglades: a pregnant female more than 17ft (5.2 metres) long and weighing 140lb, or 63.5kg.
The team from the Big Cypress National Preserve posted news of their record-setting catch in a Facebook post that also noted the giant reptile was carrying 73 eggs.
Environmentalists have been struggling to find ways to eradicate Burmese pythons, a non-native species, from the 1.5m-acre wilderness since the 1980s, when some were released into the wild as overgrown pets. Others escaped from a breeding facility wrecked by Hurricane Andrew in 1992. Continue reading
The beautiful herd of Asian Elephants calmly drinking from this watering hole poses no threat to any onlooker. They’re actually sculptures made from the invasive lantana, introduced to the Indian subcontinent as an ornamental shrub by the British. The harmless looking plant is a scourge to native flora, animals and people of the regions where it’s taken over, as it literally poisons its surroundings so nothing else can survive there, destroying the natural biodiversity of the area.
30 of these extraordinary, life-sized works of art have been on display in Kerala, at Kochi’s South Beach, coinciding with the Kochi-Muziris Biennale. The outdoor exhibit, entitled Co-Exist: Matriarchs for a Whole Earth, is on display for only until the end of February, after which it will travel to Bangalore and New Delhi. In 2020, the elephant models will be taken to England where they will be displayed at the Victoria and Albert Museum and the Royal Parks, both in London. In 2021, they will travel by truck across the USA, where they will finally be auctioned, the proceeds of which will go to preservation of wild animals.
The project is a collaboration between multiple organizations, designers and indigenous community artisans. Members of the Ashoka Trust Trust for Research in Ecology & the Environment (ATREE) devised a way to safely craft with lantana as a raw material and support for the making and display of lantana elephants is through the NGOs Elephant Family, The Real Elephant Collective (TREC), and The Shola Trust.
Highlighting the cause of nature and wildlife conservation at a global scale, the Lantana elephants are part of a greater initiative to raise funds for conservation and help people and elephants live together more harmoniously.
On February 7, if you are wandering around the popular South Beach in Fort Kochi, you are sure to come across a magnificent herd of 100 Asian elephants.
If you are wondering about the possibility of such a huge congregation of these beings at one place, let us break the news.
These are beautifully sculpted life-size elephants that have been made by tribal artisans from Thorapalli in Gudalur using Lantana camara or Lantana, a toxic invasive weed.
Lantana elephants are part of a greater initiative to raise funds for conservation and help people and elephants live together more harmoniously.
“Our vision is to bring Asia’s elephants and the issues they face out of India and the shadow cast by the African ivory crisis. With Asian elephants numbering only a tenth of their African counterparts, the importance of this unique migration cannot be underplayed. The survival of a species is at stake,” says Ruth Ganesh, principal trustee and the creative force of Elephant Family.
She had conceptualised the Lantana herd along with Shubhra Nayar of TREC. Modelled on real elephants from the Gudalur-Pandalur region, in its bid to raise awareness and funds for the conservation of Asian elephants, this unique project is also clearing the harmful Lantana from the Nilgiri forests while providing livelihoods to about 70 artisans from the Paniya, Bettakurumba and Soliga communities.
With their inherent knowledge of wild elephants and their exceptional crafting skills with Lantana, these artisans are bringing life to the elephant forms, while earning a dignified income. The elephants are designed by Shubhra Nayar and Tariq T of TREC, with Subhash Gautam overseeing the process. Continue reading
Two years of working in southern Chile taught me just enough about the complexity of this particular issue (among the many complex issues in our practice)to appreciate the article below by Emma Marris, who we already knew to be provocative, enough that she could challenge Bill McKibben two minutes into her TED talk, and does so convincingly. The primary reason I appreciate this article, is the same reason this platform has showcased the best of this genre of writers over the years. Scientists, translated into regular language we non-scientists can understand:
Invasive species are sometimes trapped, poisoned, and shot in large numbers to save native species from extinction. Some scientists say the bloodshed isn’t worth it.
The desert of south-central Australia is crenellated with sandstone hills in shades of ivory, crimson, and apricot. The ground is littered with dead trees and tree limbs, big hunks of transparent mica, dried cow dung, and thousands of stone spearheads and blades made by the Aboriginal people who lived here for tens of thousands of years—and live here still. Around the few water holes are the doglike tracks of dingoes, wild canines that were brought to Australia thousands of years ago and are now the country’s top predators.
I have come to the Evelyn Downs ranch, on the famously remote highway between Adelaide and Alice Springs, to meet Arian Wallach, a conservationist who thinks there is too much killing in conservation. Wallach has come to this massive 888-square-mile ranch because it is one of the few places in Australia where people aren’t actively killing wild animals. Tough, outback Herefords share the landscape with kangaroos, wild horses, wild donkeys, camels, emus, cats, foxes, native rodents, dingoes, and very large antediluvian-looking reptiles called perenties. Of the animals on this list, dingoes, cats, foxes, horses, camels, and donkeys are all killed in large numbers throughout Australia—but not here. Wallach has convinced the owners to experiment with a more hands-off approach. Continue reading
These three pairs of words in the post title, placed together in this order in a search engine, produce some interesting results from around the world. And today we find one more to add to the database. Thanks to National Public Radio (USA)’s Colin Dwyer for sharing this story:
There are no other birds quite like them in the world. The South Georgia pipit and pintail are so distinctive in the grand pantheon of ornithology, in fact, they draw their names from the one place they’ve made their home: South Georgia Island, sitting lonely in the forbidding South Atlantic not far from Antarctica.
Yet even in such a remote location, surrounded by penguins, fur seals and seemingly endless ocean, the birds have long been besieged by tiny alien invaders: rodents. Since the first European ships arrived in the late 18th century bearing rodents as stowaways, the voracious predators have devastated the South Georgia birds — which, with no trees to nest in, must make their vulnerable homes on the ground or in burrows.
Now, after more than two centuries, those invaders have been rebuffed. Continue reading
Thanks to Ted Williams at Cool Green Science for this article about the eviction of an invasive species in a remote location with charismatic species both native and introduced:
Early in the 20th century settlers on the islands of Chañaral and Choros off northern Chile had a brainstorm: They’d create a ready supply of fresh meat by unleashing European rabbits.
It worked out as well as rabbit introduction in Australia. Continue reading
Practitioner exchange as a form of capacity building represents a departure from more traditional approaches such as technical assistance or deployment of expert advisors. In the latter case, external experts are relied on to share successful solutions with which they are familiar only through research, and may therefore lack a complete understanding of the full range of factors and potential pitfalls that could influence the successful implementation of an approach elsewhere.
Blue Ventures has been very active in practitioner exchanges for some time, focused on sharing its pioneering work on the use of periodic, short-term fishery closures as an effective solution to balancing species conservation and livelihoods. Continue reading
Conservationists have been sounding the alarm over invasive species for years, warning of the damage they can cause to habitats and native animals. But in Florida, an invasive snail might be helping an endangered bird species come back from the brink, researchers say.
The population of North American snail kites — birds that use curved beaks and long claws to dine on small apple snails in the Florida Everglades — had been dwindling for years, from 3,500 in 2000 to just 700 in 2007. Things began to look particularly bleak in 2004, when a portion of the Everglades was invaded by a species of larger snail that the birds had historically struggled to eat. Ornithologists assumed the shift would hasten the snail kite’s decline. Continue reading
Two days ago we were intrigued by the notion; today, not so much. Is it a cat fight between two of the science writers most often linked to in these pages? Or perhaps it is an example of how scientific consensus is built:
In 2013, scientists discovered a new way to precisely edit genes — technology called Crispr that raised all sorts of enticing possibilities. Scientists wondered if it might be used to fix hereditary diseases, for example, or to develop new crops.
One of the more intriguing ideas came from Kevin M. Esvelt and his colleagues at Harvard University: Crispr, they suggested, could be used to save endangered wildlife from extinction by implanting a fertility-reducing gene in invasive animals — a so-called gene drive. Continue reading
Thanks to Ed Yong and his editors at The Atlantic for this story on one country’s approach to rats:
The nation wants to eradicate all invasive mammal predators by 2050. Gene-editing technology could help—or it could trigger an ecological disaster of global proportions.
The first thing that hit me about Zealandia was the noise.
I was a 15-minute drive from the center of Wellington, New Zealand’s capital city, but instead of the honks of horns or the bustle of passersby, all I could hear was birdsong. It came in every flavor—resonant coos, high-pitched cheeps, and alien notes that seemed to come from otherworldly instruments. Continue reading
Ants are the masters of the planet we live on. There is no escaping that. But if these dogs can protect us from some of the more sinister ants, we have these trainers to thank:
Tobias is a Labrador retriever with one job: sniffing out invasive Argentine ants wherever they hide. He’s really good at it, and with his help, a fragile island ecosystem may be spared a repeat inundation with the pests.
Santa Cruz Island is 25 miles off the coast of Southern California, part of Channel Islands National Park. The island’s rich, rugged environment — which includes more than 1,000 kinds of plants and animals, including the bald eagle and the island fox — is threatened by Argentine ants, one of the world’s most successful and wily invasive species. Continue reading
By coincidence two days in a row we have encountered important stories related to bees–yesterday’s more inspirational and this one more troubling:
There is one small field on Michael Sullivan’s farm, near the town of Burdette, Ark., that he wishes he could hide from public view.
The field is a disaster. There are soybeans in there, but you could easily overlook them. The field has been overrun by monsters: ferocious-looking plants called pigweeds, as tall as people and bursting with seeds that will come back to haunt any crops that Sullivan tries to grow here for years to come.
“I’m embarrassed to say that we farm that field,” Sullivan says. “We sprayed it numerous times, and it didn’t kill it.”
These weeds have become resistant to Sullivan’s favorite herbicides, including glyphosate, which goes by the trade name Roundup.
Yet the rest of Sullivan’s farm is beautiful. As farmers like to say, the fields are “clean.” There is not a weed to be seen. Continue reading
With big weather news recently holding our attention, it is easy to miss smaller scale natural disasters, so thanks to E. Tammy Kim for ensuring this story made it to our pages:
Just after the thrill of the total solar eclipse, a troubling nature story emerged from northwestern Washington State. On August 22nd, Cooke Aquaculture, a multibillion-dollar seafood company, reported that, three days earlier, extreme tides coinciding with the eclipse had torn apart its enormous salmon farm off Cypress Island, a teal idyll near the college town of Bellingham.
