It is a Friday night at 7:30, but instead of going out or watching a film, I've taken a train to a market town in Wiltshire to join volunteers from a toad patrol. These dedicated individuals sacrifice their evenings to protect the local toad population.

An Alarming Decline in Population

The common toad is growing more uncommon. A latest study conducted by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since the mid-1980s. Observing a creature that has been a fixture of the British countryside in decrease 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."

Since 1985, Britain's toad numbers have nearly been cut in half

The Danger from Roads

Though the study didn't examine the reasons for the decline, traffic is a major factor. Calculations suggest that 20 tons of toads are killed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be content to mate "if you left out a bucket of water," toads prefer large ponds. Their capacity to remain away from water for longer than frogs means they can travel further to find them – sometimes hundreds of metres. They tend to follow their ancestral migration routes – it's common for mature amphibians to go back to their birth pond to mate.

Breeding Patterns

Appropriately enough, the first toads start their journey for a mate around February 14th, but others travel as late as spring, waiting until it gets night and moving through the night. During that period, toads begin migrating from where they have been hibernating "almost simultaneously."

One volunteer, who grew up in the region and has been working to save its toad population since he was a boy, notes that "They've got just one focus: to go and have an orgy." If their route crosses a street, they could all get run over, and that breeding season would be lost – stopping a new generation of toads from being born.

Rescue Groups Across the United Kingdom

Seeing many of dead toads on local roads "inherently strikes a chord with people," and has led to the creation of toad patrols throughout the UK – hundreds of organizations are officially listed with a national initiative. These teams collect toads and carry them across roads in containers, as well as recording the quantity of toads they encounter and advocating for other protection measures, such as road closures and amphibian passages.

Volunteers usually work during the breeding period, when toad crossings are more regular. However, this means they can overlook numbers of toadlets, which, having been eggs and then juveniles, exit their ponds over an unpredictable schedule in late summer. Because of their small stature – just a couple of cm 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, one local team, who are in their eighth season of operating, go out year-round – not nightly, but when weather are damp, or if a member has reported about a amphibian spotting in their group chat. When I ask to join them on patrol, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a arid period – but several of the volunteers gamely agree to walk up and down their area with me and see what we can find. "Should anyone can locate any toads tonight, that pair will find one," says the patrol manager, pointing to her teenage child and the experienced member. We've been out for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to check under some wood.

Community Participation

The family duo joined the group a year and a half ago. The teenager loves all things nature-related and has an ambition to become a conservationist, so his parent started to search for activities they could do jointly to help local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the team was seeking a fresh coordinator lately, she volunteered for the role.

The youth, too, has played an important role in the group. A video he created, 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 evening and morning from late winter through to spring. The majority of motorists duly avoided the road.

Additional Species and Difficulties

A few vehicles go by when I'm out on patrol and we find some casualties as a result – no toads, but three squashed newts. We spot one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which dances in his palms. Yet in spite of the team's best efforts to let me see a toad, the local population has obviously settled down for the winter. It seems that I wouldn't have had any better success elsewhere in the nation – all the rescue teams I reach out to clarify that it's very difficult 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 generously made the effort to look for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the title: "None found." However, in February and March, he informs me, the team expects to help approximately ten thousand adult toads across the road.

Impact and Limitations

How much of a difference can these groups truly achieve? "The fact that people 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 rescue teams 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 resulted in 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 toxic plants, which can be toxic to toads. Warmer cold seasons also cause toads to wake up from their dormancy more often, disrupting the energy conservation crucial to their existence. Loss of environment – especially the loss of large ponds – is another menace.

Researchers are "often concerned about putting too much of a utilitarian spin on wildlife," however "There is a big value in just their presence." But toads do have an important role in the food chain, eating pretty much any invertebrates or tiny organisms they can swallow and in turn sustaining a variety of birds and mammals, such as wildlife. Improving situations for toads – such as creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a wide range of other species."

Cultural Significance

Another reason to work to preserve toads present is their "historical significance," notes an expert. Myths and folklore around toads go back {centuries|hundred
