It's Friday evening at half past seven, but instead of heading to the pub or relaxing at home, I've taken a train to a market town in the countryside to join volunteers from a amphibian rescue group. These committed people sacrifice their evenings to safeguard the local toad population.

A Worrying Decline in Numbers

The common toad is becoming increasingly uncommon. A latest research conducted by an amphibian and reptile charity revealed that the UK toad population have dropped by half since the mid-1980s. Observing a creature that has been a stalwart of the British countryside in decline is described as "concerning" by researchers. Toads "don't need very specific conditions" and "ought to live quite well in most of habitats in Britain," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."

Since 1985, Britain's toad numbers have nearly been cut in half

The Danger from Traffic

Though the study didn't examine the causes for the decline, cars certainly plays a part. Estimates suggest that 20 tonnes of toads are killed on UK roads every year – that is, several hundred thousand. In contrast to frogs, which would probably be content to mate "with just a bucket of water," toads prefer big bodies of water. Their ability to stay out of water for longer than frogs means they can travel further to reach them – sometimes long distances. They tend to stick to their traditional paths – it's common for mature amphibians to go back to their natal pond to mate.

Breeding Habits

Appropriately enough, the initial amphibians begin their quest for a mate around Valentine's day, but others travel as far as spring, until it gets night and moving through the night. During that period, toads begin migrating from wherever they have been overwintering "almost simultaneously."

One volunteer, who was raised in the area and has been working to save its toad population since he was a child, notes that "They've got just one focus: to go and have an orgy." If their path happens to a road, they could all get run over, and that mating period would never happen – stopping a new generation of toads from being produced.

Toad Patrols Across the United Kingdom

Seeing hundreds of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the creation of rescue teams across the UK – 274 groups are currently registered with a countrywide program. These groups collect toads and transport them across roads in containers, as well as recording the number of toads they encounter and lobbying for other protection measures, such as road closures and amphibian passages.

Patrols usually work during the breeding period, when amphibian movements are frequent. However, this means they can overlook numbers of young toads, which, having existed as eggs and then juveniles, exit their ponds over an unpredictable schedule in the end of summer. Because of their size – just a couple of cm wide – "they are destroyed by vehicles." And as being hit "basically turns them into mush," it's more difficult to get data on them. At least when mature amphibians are lost, their carcasses can be counted.

Year-Round Work

In contrast to many groups, one local team, who are in their eighth season of functioning, go out throughout the year – not nightly, but when weather are damp, or if someone has reported about a amphibian spotting in their messaging app. When I request to accompany them on patrol, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but several of the volunteers willingly accept to patrol their route with me and search for any toads. "If anyone can find any toads tonight, those two will spot one," says the group coordinator, indicating her teenage child and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have climbed over a barbed wire fence to check under some wood.

Family Participation

The family duo joined the patrol a while back. The youngster loves all things nature-related and has an ambition to become a environmentalist, so his mother started to look for things they could do together to help local wildlife. Now she loves it as much as he does, the middle-aged small business owner explains – so when the group was looking for a fresh coordinator lately, she decided to step up.

The youth, too, has played an important role in the group. A video he created, imploring the local council to close a road through a nature reserve during migration season, influenced the outcome the team's way. After a twelve months of campaigning, the council approved an "access-only" rule between evening and morning from February through to April. The majority of motorists duly avoided the route.

Additional Species and Challenges

Several vehicles go past when I'm out on patrol and we find some victims as a result – no amphibians, but three squashed newts. We see one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which moves in his hands. Yet despite the group's best efforts to show me a toad, the local population has clearly gone dormant for the colder months. It seems that I couldn't have found any better success elsewhere 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

One email I get from a different helper, who has kindly made the effort to check for toads in a noted location, considered the largest accurately monitored toad group in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he tells me, the team plans to assist approximately 10,000 mature amphibians over the street.

Effectiveness and Challenges

What level of impact can these groups actually make? "The reality that people are performing this consistently on chilly, wet and miserable late nights is remarkable," notes an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – not least because vehicles is not the only threat.

Additional Threats

The global warming has meant longer periods of dry weather, which create the poor environment for some of the animals that toads eat, such as invertebrates, while higher water temperatures have led to an rise of blue-green algae, which can be harmful to toads. Warmer cold seasons also cause toads to emerge from their hibernation more frequently, disrupting the resource preservation vital to their life cycle. Loss of environment – especially the disappearance of big water bodies – is an additional threat.

Experts are "always a bit worried about overemphasizing practical benefits on wildlife," but "It's important in just their presence." But toads play an significant part in the ecosystem, consuming pretty much any small creatures or small animals they can swallow and in turn sustaining a variety of predators, such as wildlife. Improving situations for toads – such as building water habitats, conserving woodland and installing toad tunnels – "we'll improve them for a wide range of other species."

Cultural Importance

An additional motive to try to keep toads around is their "important cultural value," adds an expert. Legends and tales around toads date back {centuries|hundred
