It's Friday evening at half past seven, but rather than heading to the pub or relaxing at home, I've taken a train to a town in the countryside to join local helpers from a amphibian rescue group. These committed people give up their evenings to safeguard the native amphibian community.

A Worrying Decline in Numbers

The common toad is growing more rare. A latest study led by an wildlife conservation group revealed that the British common toad numbers have dropped by half since the mid-1980s. Observing a creature that has been a fixture of the UK landscape in decline is described as "concerning" by experts. Toads "don't require very specific conditions" and "should be able to live successfully in most of habitats in the UK," so if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

Toad populations across the UK have declined by almost 50% since the 1980s

The Threat from Roads

Though the research didn't cover the causes for the drop, cars is a major factor. Calculations indicate that 20 tonnes of toads are killed on UK roads annually – that is, several hundred thousand. In contrast to frogs, which might be happy to mate "if you left out a bucket of water," toads favor big bodies of water. Their ability to stay out of water for more time than frogs allows they can journey farther to find them – often hundreds of metres. They usually stick to their ancestral migration routes – it's common for adult toads to return to their natal pond to mate.

Migration Patterns

Fittingly, the initial amphibians start their journey for a mate around February 14th, but some move as late as April, waiting until it gets dark and travelling through the night. During that time, toads start moving from wherever they have been overwintering "all pretty much at the same time."

One volunteer, who grew up in the region and has been trying to protect its amphibians since he was a boy, notes that "Their sole purpose: to go and have an orgy." If their path crosses a road, they could all get run over, and that breeding season would never happen – preventing a next generation of toads from being born.

Rescue Groups Throughout the UK

Seeing many of dead toads on nearby streets "inherently strikes a chord with people," and has led to the creation of toad patrols throughout the UK – 274 groups are officially listed with a national initiative. These teams pick up toads and carry them across roads in containers, as well as recording the quantity of toads they encounter and advocating for other protection measures, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the migration season, when toad crossings are more regular. However, this means they can overlook numbers of toadlets, which, having been spawn and then tadpoles, exit their water habitats over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "basically turns them into mush," it's more difficult to collect information on them. At least when adult toads are killed, their remains can be counted.

Annual Work

In contrast to many groups, one local team, who are in their eighth season of operating, go out throughout the year – not every night, but whenever weather are damp, or if someone has posted about a toad sighting in their group chat. When I ask to join them on duty, they concede it is "not a toady night" – toad hibernation season has started and it's been a dry day – but a few of the volunteers gamely agree to patrol their route with me and search for any toads. "If anyone can find any toads tonight, that pair will find one," says the group coordinator, pointing to her 14-year-old son and the experienced member. After for 120 minutes without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some wood.

Community Participation

The mother and son joined the group a year and a half ago. The teenager loves all things wildlife and has an goal to become a conservationist, so his mother started to search for activities they could do together to protect native animals. Now she loves it as much as he does, the middle-aged entrepreneur tells me – so when the team was looking for a fresh coordinator lately, she volunteered for the role.

The youth, too, has been instrumental in the group. A clip he created, imploring the municipal authority to close a street through a nature reserve during migration season, swung the decision the team's way. After a year of campaigning, the authority agreed to an "restricted access" rule between evening and morning from February through to April. The majority of motorists duly avoided the road.

Additional Species and Challenges

Several vehicles go by when I'm out on duty and we find some casualties as a consequence – no toads, but several crushed salamanders. We see one living newt as well, and the youngster is particularly pleased to see a harvestman, which moves in his hands. Yet despite the group's hardest attempts to show me a toad, the native community has clearly gone dormant for the winter. It appears that I couldn't have found any better success anywhere else in the nation – all the patrol groups I reach out to explain that it's near-impossible at this season.

The group expects to help approximately 10,000 adult toads across the road

A message I get from another volunteer, who has kindly made the effort to check for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he informs me, the team expects to help approximately 10,000 mature amphibians over the street.

Impact and Challenges

What level of impact can these groups truly achieve? "The fact that volunteers are performing this consistently on cold, damp and unpleasant late nights is remarkable," says an expert. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – not least because vehicles is just one danger.

Additional Threats

The climate crisis has meant extended spells of drought, which create the wrong conditions for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have led to an rise of blue-green algae, which can be harmful to toads. Milder winters also lead toads to emerge from their dormancy more frequently, disrupting the energy conservation crucial to their existence. Habitat destruction – particularly the loss of large ponds – is an additional threat.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just having these animals around." But toads play an important role in the food chain, eating pretty much any small creatures or tiny organisms they can swallow and in turn sustaining a variety of birds and mammals, such as wildlife. Improving conditions for toads – ie building water habitats, protecting forests and constructing toad tunnels – "benefits for a whole bunch of additional wildlife."

Cultural Importance

An additional motive to try to keep toads around is their "historical significance," adds an expert. Legends and tales around toads go back {centuries|hundred
