It is Friday evening at half past seven, but instead of going out or relaxing at home, I've taken a train to a market town in Wiltshire to meet up with local helpers from a amphibian rescue group. These committed people sacrifice their nights to protect the local toad population.

A Worrying Drop in Numbers

The common toad is growing more uncommon. A latest study conducted by an amphibian and reptile charity revealed that the UK toad population have almost halved since the mid-1980s. Observing a species that has been a fixture of the UK landscape in decrease is described as "concerning" by experts. Toads "don't require very specific conditions" and "ought to live quite well in most of habitats in the UK," so if even they are not managing to survive, "it indicates 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 study didn't examine the reasons for the drop, traffic certainly plays a part. Estimates suggest that 20 tons of toads are crushed on UK roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be happy 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 long distances. They tend to follow their traditional paths – it's typical for adult toads to return to their natal pond to mate.

Breeding Patterns

Fittingly, the initial amphibians begin their quest for a partner around Valentine's day, but some move as late as spring, waiting until it gets night and travelling after sunset. During that time, toads start moving from wherever they have been hibernating "all pretty much at the same time."

A local helper, who grew up in the area and has been working to save its amphibians since he was a boy, explains that "Their sole purpose: to go and mate." If their route crosses a street, they could all get run over, and that mating period would be lost – stopping a next generation of toads from being produced.

Rescue Groups Throughout the United Kingdom

Finding many of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the formation of toad patrols across the UK – hundreds of organizations are officially listed with a countrywide program. These teams collect toads and transport them across roads in buckets, as well as counting the number of toads they encounter and advocating for other safety solutions, such as road closures and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this implies they can miss numbers of toadlets, which, having existed as eggs and then juveniles, leave their water habitats over an irregular timetable in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by vehicles." And as being hit "essentially crushes them," it's harder to get data on them. At least when adult toads are lost, their remains can be tallied.

Annual Work

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 conditions are warm and wet, or if a member has posted about a amphibian spotting in their group chat. When I request to accompany them on duty, they concede it is "not ideal conditions" – winter dormancy has started and it's been a dry day – 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 find one," says the patrol manager, pointing to 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 inspect beneath some wood.

Community Involvement

The family duo became part of the group a year and a half ago. The youngster adores all things wildlife and has an ambition to become a environmentalist, so his mother started to search for things they could do together to help native animals. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the group was seeking a fresh coordinator lately, she volunteered for the role.

The teenager, too, has played an important role in the organization. A video he made, urging the local council to close a street through a nature reserve during breeding time, swung the decision the team's way. After a year of campaigning, the council agreed to an "access-only" rule between evening and morning from late winter through to spring. Most drivers respected and avoided the route.

Other Wildlife and Difficulties

Several cars 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 live amphibian as well, and the teenager is particularly pleased to see a harvestman, which moves in his hands. Yet despite the team's best efforts to show me a toad, the native community has clearly settled down for the winter. It appears that I wouldn't have had any better success elsewhere in the nation – all the rescue teams I contact explain that it's near-impossible at this time of year.

They project rescuing nearly 10,000 grown amphibians during migration

A message I receive from another volunteer, who has generously taken the trouble to check for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, reaches me with the subject line: "No toads." However, in late winter, he tells me, the team plans to assist approximately 10,000 mature amphibians across the road.

Impact and Challenges

How much of a difference can these groups truly achieve? "The fact that people are doing this regularly on chilly, wet and miserable late nights is remarkable," notes an expert. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they can't stop it completely – not least because traffic is just one danger.

Additional Threats

The global warming has meant extended spells of dry weather, which create the poor environment for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused an rise of blue-green algae, which can be toxic to toads. Milder winters also cause toads to wake up from their hibernation more often, interfering with the resource preservation crucial to their existence. Habitat destruction – especially the loss of large ponds – is another menace.

Researchers are "often concerned about putting too much of a utilitarian spin on wildlife," but "It's important in just their presence." But toads do have an important role in the food chain, consuming pretty much any small creatures or small animals they can fit in their mouths and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Enhancing situations for toads – ie building water habitats, conserving woodland and constructing toad tunnels – "we'll improve them for a whole bunch of additional wildlife."

Historical Importance

An additional motive to work to preserve toads present is their "historical significance," adds an expert. Myths and folklore around toads go back {centuries|hundred
