It is a Friday night at 7:30, but instead of heading to the pub or relaxing at home, I've caught a train to a market town in Wiltshire to join local helpers from a toad patrol. These dedicated individuals sacrifice their evenings to protect the local toad population.

A Worrying Drop in Numbers

The common toad is growing more rare. A latest study led by an wildlife conservation group showed 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 labeled "worrying" by experts. Toads "don't require very particular environments" and "ought to live quite well in most of areas in the UK," so if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The UK toad population has almost halved since 1985

The Threat from Roads

Though the study didn't cover the reasons for the decline, traffic is a major factor. Estimates suggest that 20 tons of toads are crushed on UK roads every year – that is, several hundred thousand. Unlike frogs, which might be content to mate "if you left out a small container," toads prefer big bodies of water. Their capacity to remain away from water for more time than frogs means they can journey farther to find them – often long distances. They usually stick to their ancestral migration routes – it's common for adult toads to go back to their birth pond to mate.

Breeding Patterns

Appropriately enough, the first toads begin their quest for a mate around Valentine's day, but some move as late as April, waiting until it gets dark and moving after sunset. 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 region and has been trying to protect its toad population since he was a boy, explains 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 be lost – stopping a new generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding many of dead toads on nearby streets "resonates deeply with people," and has led to the formation of toad patrols across the UK – 274 groups are currently registered with a countrywide program. These teams pick up toads and transport them over streets in containers, as well as counting the quantity of toads they encounter and advocating for other safety solutions, such as blocked roads and underground wildlife tunnels.

Patrols tend to operate during the breeding period, when amphibian movements are more regular. However, this means they can overlook groups of toadlets, which, having existed as eggs and then juveniles, leave their ponds over an irregular timetable in the end of summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "essentially crushes them," it's more difficult to get data on them. At least when adult toads are killed, their remains can be tallied.

Annual Work

In contrast to many groups, 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 someone has posted about a toad sighting 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 arid period – but a few of the helpers gamely agree to walk up and down their route with me and see what we can find. "If anyone can locate any toads tonight, that pair will spot one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some logs.

Community Involvement

The mother and son joined the group a year and a half ago. The youngster adores all things wildlife and has an ambition to become a conservationist, so his mother started to search for things they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the team was seeking a fresh coordinator recently, 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 road through a nature reserve during breeding time, swung the decision the group's way. After a twelve months of lobbying, the council approved an "access-only" rule between 5pm and 5am from late winter through to spring. The majority of motorists duly avoided the route.

Other Wildlife and Challenges

Several cars go past when I'm out on patrol and we find some victims as a consequence – no toads, but three squashed newts. We see one live amphibian as well, and the youngster is particularly pleased to see a daddy longlegs, which moves in his hands. Yet in spite of the team's best efforts to let me see a toad, the native community has clearly gone dormant for the colder months. It appears that I wouldn't have had any more luck elsewhere in the nation – all the rescue teams I contact explain that it's very difficult at this time of year.

They project rescuing nearly 10,000 grown amphibians during migration

One email I receive from another volunteer, who has generously taken the trouble to look for toads in a noted location, considered the biggest tracked toad population in the UK, reaches me with the subject line: "No toads." However, in late winter, he informs me, the group expects to help approximately 10,000 mature amphibians across the road.

Impact and Limitations

What level of impact can these organizations actually make? "The reality that volunteers are doing this regularly on cold, damp and unpleasant late nights is quite extraordinary," says an researcher. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because vehicles is not the only threat.

Other Dangers

The climate crisis has meant longer periods of dry weather, which create the poor environment for some of the creatures that toads eat, such as invertebrates, 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 wake up from their hibernation more frequently, disrupting the energy conservation crucial to their life cycle. Habitat destruction – especially the loss of large ponds – is another menace.

Experts are "always a bit worried about overemphasizing practical benefits on biodiversity," but "It's important in just having these animals around." But toads do have an significant part in the ecosystem, consuming pretty much any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a variety of predators, such as hedgehogs and otters. Enhancing situations for toads – such as creating more ponds, protecting forests and constructing amphibian passages – "benefits for a whole bunch of other species."

Cultural Importance

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