It's Friday evening at 7:30, but instead of going out or watching a film, I've caught a train to a market town in the countryside to meet up with volunteers from a amphibian rescue group. These committed people sacrifice their nights to protect the native amphibian community.

An Alarming Drop in Population

The Bufo bufo is becoming increasingly uncommon. A latest study led by an wildlife conservation group showed that the UK toad population have almost halved 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 quite well in most of areas in Britain," meaning if even they are not managing to survive, "it indicates that things are not as they should be."

The Threat from Roads

Though the study didn't cover the reasons for the decline, cars certainly plays a part. Calculations indicate that 20 tons of toads are crushed on British roads annually – in other words, several hundred thousand. Unlike frogs, which would probably be content to mate "if you left out a bucket of water," toads favor large ponds. Their capacity to remain away from water for more time than frogs means they can journey farther to reach them – sometimes hundreds of metres. They tend to follow their ancestral migration routes – it's common for mature amphibians to go back to their natal pond to mate.

Breeding Patterns

Fittingly, the first toads begin their quest for a partner around Valentine's day, but others travel as late as spring, waiting until it gets dark and moving through the night. During that period, toads start moving from where they have been overwintering "all pretty much at the same time."

One volunteer, who grew up in the area and has been trying to protect its toad population since he was a boy, notes that "They've got just one focus: to go and mate." If their path crosses a road, they could all get run over, and that breeding season would be lost – stopping a next generation of toads from being produced.

Toad Patrols Throughout the United Kingdom

Seeing hundreds of dead toads 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 pick up toads and transport them across roads in buckets, as well as recording the number of toads they find and lobbying for other safety solutions, such as road closures and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when amphibian movements are more regular. However, this implies they can overlook groups of young toads, which, having been spawn and then juveniles, exit their ponds over an irregular timetable in late summer. Because of their small stature – just a couple of cm wide – "they are destroyed 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 lost, their carcasses can be counted.

Annual Work

Unlike most patrols, one local team, who are in their eighth season of functioning, go out throughout the year – not every night, but when conditions are damp, or if a member has posted about a toad sighting in their group chat. When I request to accompany them on duty, they admit it is "not a toady night" – toad hibernation season has begun and it's been a arid period – but several of the volunteers gamely agree to patrol their area with me and search for any toads. "Should anyone can find any toads tonight, that pair will spot one," says the group coordinator, indicating her 14-year-old son and the longtime volunteer. After for two hours without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some logs.

Community Involvement

The mother and son became part of the patrol a while back. The teenager loves all things wildlife and has an ambition to become a conservationist, so his mother started to look for activities they could do jointly to help local wildlife. Now she loves it as much as he does, the middle-aged small business owner tells me – so when the group was seeking a fresh coordinator recently, she decided to step up.

The teenager, too, has played an important role in the organization. A video he made, urging the municipal authority to close a road through a protected area during migration season, influenced the outcome the team's way. After a year of lobbying, the council agreed to an "access-only" restriction between 5pm and 5am from late winter through to April. The majority of motorists respected and avoided the road.

Additional Species and Challenges

Several vehicles go by when I'm out on patrol and we discover some victims as a consequence – no amphibians, but three squashed newts. We see one living newt as well, and the teenager is particularly pleased to see a harvestman, which dances in his palms. Yet despite the group's hardest attempts to let me see a toad, the local population has obviously settled down for the winter. It seems that I couldn't have found any better success anywhere else in the country – all the patrol groups I reach out to clarify that it's very difficult at this season.

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

A message I get from a different helper, who has kindly taken the trouble to look for toads in a noted location, considered the largest accurately monitored toad group in the UK, reaches me with the subject line: "None found." However, in late winter, he tells me, the group plans to assist around 10,000 mature amphibians over the street.

Effectiveness and Challenges

What level of impact can these groups actually make? "The reality that people are doing this consistently on cold, damp and unpleasant evenings is quite extraordinary," notes an expert. "That's something that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – not least because vehicles is not the only threat.

Other Dangers

The global warming has resulted in extended spells of dry weather, which create the wrong conditions for some of the creatures that toads consume, such as invertebrates, while warmer ponds have led to an rise of blue-green algae, which can be harmful to toads. Milder winters also cause toads to emerge from their dormancy more often, interfering with the energy conservation crucial to their existence. Loss of environment – 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 "It's important in just their presence." But toads do have an important role in the ecosystem, consuming almost any small creatures or small animals they can fit in their mouths and in turn sustaining a number of predators, such as hedgehogs and otters. Enhancing situations for toads – ie building water habitats, conserving woodland and constructing toad tunnels – "benefits for a whole bunch of additional wildlife."

Cultural Significance

Another reason to try to keep toads present is their "historical significance," adds an specialist. Legends and tales around toads go back {centuries|hundred
