At the crossway of Ohio, Michigan and Indiana, the corn monoculture dissolves to reveal green rolling hills and deep canyons. The rich forest is pockmarked by steep-banked ponds, taken by pulling away glaciers 10,000 years back. Standing waist-deep in a forest swimming pool, Megan Seymour scans the shrubby banks with field glasses.
A minor modification in colour and texture found in the twisted buttonbush overload exposes her quarry: a thick, shiny, copperbelly water snake (Nerodia erythrogaster neglecta). Seymour raises up her waders and ties back her hair as she prepares to get the water snake prior to it can vanish into the dirty water, taking with it among the last opportunities to save the types.

Though non-venomous, a bite from a 1.2-metre (4ft) water snake can be agonizing. But Seymour, a biologist with the United States Fish and Wildlife Service, has actually lost count of the variety of snake bites (all from non-venomous types) she has actually had, and fasts to include: “They aren’t slimy, they aren’t mean, and they aren’t trying to get you.”
The copperbelly water snake – called for its tangerine-orange underside – populated what was among the biggest wetland locations in North America. Roughly the size of Connecticut and extending from Fort Wayne in Indiana throughout much of north-west Ohio, the Great Black Swamp was home to elk, wolves, mountain lions and black bears.

In the mid-19th century, farmers started to clear the trees and drain pipes the overload to access the fertile soil concealed underneath the water. In simply 5 years, the Great Black Swamp was dry.
Today, the copperbelly water snake claims simply 50 sq km (20 sq miles) of residue overload forest in the tri-state location – somewhat smaller sized than Manhattan Island. Though the specific variety of the reptiles is not understood, professionals approximate that less than 100 people, perhaps as couple of as 40, stay.
“I think they will be gone within 20 years,” says Nathan Herbert, a land steward with the Nature Conservancy, a global not-for-profit organisation.
He thinks conserving the copperbelly water snake is necessary to the area’s ecology since it is “an umbrella species” – the conservation and preservation of this one snake likewise secures environment for lots of other decreasing types that count on the overload forest, consisting of the uncommon bobolink blackbird and the checkerspot butterfly.
When Seymour began searching for copperbelly water snakes in spring 2021, no one had seen one alive in the wild in almost three years. She spent more than 180 hours combing through the wetlands historically inhabited by the species but found none. “That was very concerning and pushed us down the road to captive propagation being the best option,” says Seymour.
Captive breeding acts as an insurance policy against extinction. Encouraging endangered species to reproduce in captivity can increase population size, maintain genetic diversity and safeguard rare species while habitat is restored for their eventual return to the wild. The Andean condor, red wolf and bald eagle were saved from extinction via captive breeding.
The US Fish and Wildlife Service is partnering with Toledo zoo, south of Detroit, to captive breed copperbelly water snakes. The zoo has successfully reared other declining native species, including the hellbender salamander and the Blanding’s turtle. No one, nevertheless, had actually attempted to breed copperbelly water snakes in captivity prior to.
In 2022, with the help of private landowners, Seymour found and caught six copperbelly water snakes – three males and three females. “Finding six snakes was insanity,” says Seymour. “After we got the first one, I was just shaking.”
The snakes have adjusted quickly to captivity at Toledo zoo. “They are doing really well,” says Seymour. “They are eating, shedding and behaving as they should.”
In a small back room, hidden away from the zoo’s visitors, a lots nontransparent plastic enclosures line the wall. Each holds a water meal, a conceal and 2 child copperbelly water snakes patiently awaiting a meal of sliced fish.
Just 4 months after she was captured, among the women brought to life 24 infants, the very first copperbelly water snakes to be born in captivity. Each juvenile snake sports a subtle blotched pattern that rapidly fades to black as they grow. The stubborn bellies are already tinged with their name copper color.

Dr Matthew Cross, a preservation biologist at Toledo zoo, sees the captive breeding and reintroduction of the copperbelly water snake as an opportunity to best our eco-friendly wrongs. As with medical physicians’ Hippocratic oath, preservation biologists hold an ethical dedication to avoid termination. “Conservation biology is a crisis discipline,” says Cross. “We are always playing catch-up.”
Seymour, Cross and the group at Toledo zoo have actually dedicated the next years and a half to conserving the copperbelly water snake. The zoo-reared snakes might go back to the wetlands where their moms and dads when lived as early as next year. If captive breeding succeeds, “we are looking at potentially thousands of baby snakes over the next 15 years”, says Seymour.
