It's a Friday evening at 7:30, but rather than heading to the pub or relaxing at home, I've taken a train to a town in the countryside to meet up with volunteers from a toad patrol. These dedicated individuals sacrifice their nights to protect the local toad population.

A Worrying Drop in Numbers

The common toad is becoming increasingly uncommon. A latest study led by an wildlife conservation group showed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decrease is described as "worrying" by experts. Toads "don't require very specific conditions" and "should be able to live successfully in the majority of habitats in Britain," meaning if even they are not managing to survive, "it indicates that things are not as they should be."

The UK toad population has almost halved since 1985

The Threat from Traffic

Though the research didn't examine the causes for the decline, cars certainly plays a part. Calculations indicate that 20 tons of toads are crushed on UK roads every year – in other words, several hundred thousand. Unlike frogs, which might be happy to mate "if you left out a small container," toads favor big bodies of water. Their ability to stay out of water for longer than frogs allows they can journey farther to reach them – often hundreds of metres. They tend to stick to their traditional paths – it's common for mature amphibians to go back to their natal pond to mate.

Migration Patterns

Appropriately enough, the first toads begin their quest for a partner around February 14th, but some move as late as spring, until it gets dark and travelling through the night. During that time, toads begin migrating from where they have been overwintering "all pretty much at the same time."

One volunteer, who was raised in the area and has been working to save its amphibians since he was a boy, notes that "They've got just one focus: to go and have an orgy." If their route crosses a street, they could be killed by traffic, and that mating period would be lost – preventing a next generation of toads from being born.

Rescue Groups Across the UK

Seeing hundreds of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the formation of rescue teams throughout the UK – hundreds of organizations are currently registered with a national initiative. These teams collect toads and transport them over streets in containers, as well as recording the quantity of toads they encounter and lobbying for other protection measures, such as blocked roads and amphibian passages.

Volunteers usually work during the breeding period, when toad crossings are more regular. However, this means they can overlook numbers of young toads, which, having been eggs and then juveniles, leave their ponds over an irregular timetable in late summer. Because of their small stature – just a couple of cm wide – "they can get obliterated by vehicles." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when mature amphibians are killed, their carcasses can be tallied.

Annual Efforts

In contrast to most patrols, a specific volunteer group, 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 reported about a amphibian spotting in their messaging app. When I ask to join them on patrol, they concede it is "not ideal conditions" – winter dormancy has started and it's been a arid period – but a few of the helpers willingly accept to walk up and down their route with me and search for any toads. "If anyone can locate any toads tonight, those two will spot one," says the patrol manager, indicating her teenage child and the experienced member. After for 120 minutes without a glimpse of any amphibians, and now they have scaled a barbed wire fence to check under some logs.

Community Participation

The mother and son became part of the group a year and a half ago. The youngster loves all things nature-related and has an goal to become a conservationist, so his parent started to search for things they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the 41-year-old small business owner tells me – so when the group was seeking a fresh coordinator recently, she decided to step up.

The youth, too, has played an important role in the group. A video he made, urging the local council to block a road through a nature reserve during migration season, influenced the outcome the team's way. After a year of lobbying, the council approved an "access-only" restriction between evening and morning from late winter through to spring. Most drivers respected and avoided the road.

Other Wildlife and Challenges

Several vehicles go past when I'm out on duty and we discover some casualties as a consequence – no amphibians, but three squashed newts. We see one living newt as well, and the youngster is especially excited to see a harvestman, which moves in his palms. Yet despite the group's hardest attempts to let me see a toad, the local population has clearly gone dormant for the colder months. It appears that I couldn't have found any more luck anywhere else in the country – all the patrol groups I reach out to explain that it's very difficult at this time of year.

This team anticipates assisting around ten thousand mature toads over the street

One email I receive from a different helper, who has generously taken the trouble to check for toads in a noted location, considered the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "None found." However, in late winter, he tells me, the team expects to help approximately ten thousand adult toads over the street.

Effectiveness and Challenges

How much of a difference can these organizations truly achieve? "The reality that volunteers are doing this regularly on chilly, wet and miserable late nights is quite extraordinary," notes an researcher. "That's something that very much deserves recognition." However, while rescue teams are able to reduce the drop, they can't stop it completely – not least because traffic is just one danger.

Other Dangers

The climate crisis has resulted in extended spells of dry weather, which create the wrong conditions for some of the creatures that toads eat, such as invertebrates, while higher water temperatures have led to an increase of toxic plants, which can be toxic to toads. Milder winters also lead toads to emerge from their dormancy more often, disrupting the resource preservation crucial to their existence. Habitat destruction – particularly the loss of large ponds – is an additional threat.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," however "There is a big value in just having these animals around." But toads play an significant part in the food chain, consuming almost any small creatures or small animals they can swallow and in turn sustaining a number of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – such as building water habitats, conserving woodland and installing toad tunnels – "benefits for a wide range of additional wildlife."

Cultural Importance

Another reason to work to preserve toads around is their "historical significance," notes an specialist. Myths and folklore around toads go back {centuries|hundred
