It's Friday evening at half past seven, but instead of heading to the pub or relaxing at home, I've caught a train to a market town in Wiltshire to meet up with volunteers from a amphibian rescue group. These committed people give up their evenings to safeguard the native amphibian community.

An Alarming Drop in Population

The common toad is becoming increasingly uncommon. A latest study conducted by an amphibian and reptile charity showed that the UK toad population have dropped by half since 1985. Seeing a creature that has been a fixture of the British countryside in decline is labeled "concerning" by researchers. Toads "don't need 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 the ecosystem is unbalanced."

The UK toad population has almost halved since 1985

The Threat from Roads

Though the study didn't cover the causes for the decline, traffic certainly plays a part. Estimates suggest that 20 tons of toads are killed on UK roads annually – that is, 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 capacity to remain away from water for more time than frogs means they can journey farther to reach them – sometimes long distances. They usually follow their ancestral migration routes – it's common for mature amphibians to go back to their natal pond to mate.

Breeding Habits

Fittingly, the first toads begin their quest for a partner around Valentine's day, but some move as late as spring, waiting until it gets night and travelling through the night. During that time, toads begin migrating from where they have been overwintering "almost simultaneously."

One volunteer, who was raised in the area and has been trying to protect its toad population since he was a child, notes that "Their sole purpose: to go and mate." If their path crosses a street, they could be killed by traffic, and that mating period would never happen – preventing a new generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding hundreds of toad carcasses on nearby streets "resonates deeply with people," and has led to the formation of toad patrols throughout the UK – 274 groups are currently registered with a countrywide program. These groups pick up toads and carry them over streets in buckets, as well as recording the number of toads they find and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the breeding period, when amphibian movements are frequent. However, this means they can miss numbers of young toads, which, having existed as eggs and then juveniles, leave their water habitats over an irregular timetable in the end of summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by car traffic." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are killed, their carcasses can be counted.

Year-Round Efforts

Unlike most patrols, one local team, who are in their eighth season of operating, go out throughout the year – not nightly, but whenever weather are damp, or if a member has posted about a toad sighting in their group chat. When I ask to join them on patrol, 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 walk up and down their route with me and see what we can find. "Should anyone can locate any toads tonight, those two will spot one," says the group coordinator, indicating her 14-year-old son and the longtime volunteer. After for 120 minutes without a single toad sighting, and now they have scaled a barbed wire fence to inspect beneath some logs.

Community Involvement

The mother and son became part of the patrol a year and a half ago. The youngster adores all things nature-related and has an goal to become a conservationist, so his mother started to look for things they could do together to protect local wildlife. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the group was seeking a new manager recently, she volunteered for the role.

The youth, too, has been instrumental in the group. A video he created, imploring the municipal authority to close a street through a protected area during migration season, influenced the outcome the team's way. After a twelve months of lobbying, the authority approved an "restricted access" restriction between 5pm and 5am from late winter through to April. The majority of motorists duly avoided the route.

Additional Species and Challenges

Several cars go by when I'm out on duty and we discover some casualties as a result – no toads, but several crushed salamanders. We spot one living newt as well, and the youngster is especially excited to see a daddy longlegs, which dances in his hands. Yet despite the team's hardest attempts to let me see a toad, the native community has clearly settled down 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 clarify that it's near-impossible at this time of year.

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

A message I get from a different helper, who has kindly made the effort to look for toads in a famous site, thought to be the largest accurately monitored toad population in the UK, reaches me with the title: "No toads." However, in February and March, he tells me, the group expects to help around 10,000 mature amphibians across the road.

Effectiveness and Limitations

What level of impact can these groups truly achieve? "The fact that volunteers are doing this consistently on cold, damp and unpleasant evenings is quite extraordinary," says an expert. "That's something that very much deserves recognition." However, while toad patrols are able to reduce the drop, they can't stop it completely – not least because vehicles is not the only threat.

Additional Threats

The climate crisis has meant extended spells of drought, which create the poor environment for some of the creatures that toads consume, such as worms and slugs, while higher water temperatures have led to an increase of toxic plants, which can be harmful to toads. Milder winters also cause toads to wake up from their hibernation more often, disrupting the energy conservation crucial to their existence. Loss of environment – especially the loss of big water bodies – is another menace.

Researchers are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just their presence." But toads do have an significant part in the ecosystem, consuming pretty much any invertebrates or small animals they can swallow and in turn feeding 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 – "we'll improve them for a whole bunch of other species."

Cultural Importance

An additional motive to work to preserve toads around is their "historical significance," adds an specialist. Legends and tales around toads date back {centuries|hundred
