It is a Friday night 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 join local helpers from a amphibian rescue group. These dedicated individuals sacrifice their evenings to protect the native amphibian community.

An Alarming Decline in Population

The common toad is growing more rare. A recent research conducted by an amphibian and reptile charity showed that the UK toad population have dropped by half since the mid-1980s. Seeing a species that has been a stalwart of the UK landscape in decline is described as "concerning" by researchers. Toads "don't need very particular environments" and "ought to live successfully in the majority of areas in Britain," so if even they are struggling to persist, "it kind of suggests that things are not as they should be."

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

The Threat from Roads

Though the research didn't cover the reasons for the decline, traffic certainly plays a part. Estimates indicate that 20 tonnes of toads are crushed on UK roads annually – that is, hundreds of thousands. Unlike frogs, which might be happy to mate "if you left out a bucket of water," toads prefer large ponds. Their ability to stay out of water for more time than frogs means they can journey farther to reach them – sometimes hundreds of metres. They usually follow their ancestral migration routes – it's common for mature amphibians to return to their birth pond to mate.

Breeding Patterns

Appropriately enough, the first toads begin their quest for a mate around February 14th, but some move as far as April, until it gets night and travelling after sunset. During that time, toads start moving from where they have been hibernating "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 route happens to a street, they could all get run over, and that breeding season would be lost – preventing a next generation of toads from being produced.

Toad Patrols Throughout the United Kingdom

Finding many of toad carcasses on nearby streets "inherently strikes a chord with people," and has resulted in the creation of toad patrols throughout the UK – 274 groups are currently registered with a countrywide program. These groups collect toads and transport them over streets in containers, as well as counting the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and amphibian passages.

Volunteers usually work during the breeding period, when toad crossings are more regular. However, this implies they can miss numbers of young toads, which, having been eggs and then tadpoles, exit their ponds over an unpredictable schedule in late 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 harder to collect information on them. At least when adult toads are killed, their remains can be tallied.

Year-Round Efforts

Unlike many groups, one local team, who are in their eighth season of functioning, go out year-round – not every night, but whenever weather are damp, or if someone has reported about a amphibian spotting in their group chat. When I ask to join them on duty, they concede it is "not ideal conditions" – toad hibernation season 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. "Should anyone can locate any toads tonight, those two will find one," says the patrol manager, indicating her teenage child and the experienced member. After for 120 minutes without a single toad sighting, and now they have scaled a barbed wire fence to check under some logs.

Family Involvement

The mother and son joined the patrol a year and a half ago. The youngster adores all things nature-related and has an ambition to become a environmentalist, so his mother started to search for activities they could do jointly to help local wildlife. Now she loves it as much as he does, the middle-aged entrepreneur explains – so when the group was seeking a new manager lately, she decided to step up.

The youth, too, has been instrumental in the organization. A clip he created, urging the local council to block a road through a protected area during breeding time, influenced the outcome the group's way. After a twelve months of campaigning, the authority agreed to an "access-only" restriction between 5pm and 5am from February through to spring. The majority of motorists duly avoided the road.

Other Wildlife and Difficulties

Several vehicles go past when I'm out on patrol and we discover some victims as a consequence – no amphibians, but several crushed salamanders. We see one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which dances in his palms. Yet in spite of the team's hardest attempts to let me see a toad, the local population has obviously gone dormant for the colder months. It seems that I wouldn't have had any better success anywhere else in the country – all the patrol groups I contact explain that it's very difficult at this time of year.

They project rescuing nearly 10,000 grown amphibians during migration

A message I receive from a different helper, who has generously taken the trouble to look for toads in a noted location, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he tells me, the team plans to assist around 10,000 adult toads across the road.

Impact and Limitations

How much of a difference can these organizations truly achieve? "The fact that volunteers are doing this consistently on cold, damp and unpleasant evenings is quite extraordinary," says an researcher. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – partly since vehicles is just one danger.

Additional Threats

The climate crisis has meant extended spells of drought, which cause the poor environment for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have led to an increase of blue-green algae, which can be toxic to toads. Warmer cold seasons also lead toads to emerge from their dormancy more often, disrupting the resource preservation crucial to their existence. Loss of environment – especially the loss of big water bodies – is another menace.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "There is a big value in just having these animals around." But toads do have an significant part in the food chain, consuming almost any small creatures or small animals they can swallow and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Improving situations for toads – ie creating more ponds, protecting forests and constructing toad tunnels – "benefits for a whole bunch of additional wildlife."

Cultural Importance

An additional motive to try to keep toads present is their "historical significance," adds an specialist. Myths and folklore around toads date back {centuries|hundred
