It's a Friday night at half past seven, but rather than going out or watching a film, I've caught a train to a town in the countryside to meet up with local helpers from a toad patrol. These dedicated individuals sacrifice their nights to safeguard the local toad population.

A Worrying Decline in Population

The Bufo bufo is growing more rare. A recent study led by an amphibian and reptile charity revealed that the UK toad population have almost halved since 1985. Observing a creature that has been a fixture of the UK landscape in decline is described as "concerning" by researchers. Toads "don't require very specific conditions" and "ought to live quite well in the majority of areas in the UK," meaning 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 Danger from Traffic

Though the research didn't examine the causes for the drop, cars certainly plays a part. Estimates suggest that 20 tonnes of toads are killed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be content to mate "with just a bucket of water," toads favor large ponds. Their capacity to stay out of water for more time than frogs means they can journey farther to find them – sometimes 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 Habits

Appropriately enough, the initial amphibians begin their quest for a mate around Valentine's day, but some move as late as spring, until it gets dark and moving through the night. During that time, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."

A local helper, who was raised in the area and has been working to save its toad population since he was a boy, explains that "They've got just one focus: to go and have an orgy." If their path happens to a street, they could be killed by traffic, and that breeding season would be lost – stopping a next generation of toads from being born.

Rescue Groups Throughout the UK

Finding many of toad carcasses on local roads "resonates deeply with people," and has led to the creation of toad patrols throughout the UK – hundreds of organizations are officially listed with a countrywide program. These teams pick up toads and transport them across roads in buckets, as well as counting the number of toads they encounter and lobbying for other protection measures, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the breeding period, when toad crossings 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 small stature – just one or two centimetres wide – "they can get obliterated by vehicles." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when adult toads are killed, their remains can be tallied.

Year-Round Work

In contrast to most patrols, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not nightly, but when conditions are warm and wet, or if a member has posted about a amphibian spotting in their group chat. When I ask to join them on patrol, they admit it is "not ideal conditions" – toad hibernation season has started and it's been a dry day – but several of the helpers willingly accept to patrol their route with me and see what we can find. "Should anyone can find any toads tonight, those two will spot one," says the patrol manager, indicating her teenage child and the longtime volunteer. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some wood.

Family Involvement

The mother and son joined the patrol a year and a half ago. The teenager loves all things nature-related and has an goal to become a environmentalist, so his mother started to search for things they could do together to help local wildlife. Now she loves it as much as he does, the 41-year-old 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 created, urging the local council to block a street through a protected area during breeding time, swung the decision the group's way. After a twelve months of campaigning, the council approved an "access-only" restriction between evening and morning from late winter through to April. Most drivers duly avoided the road.

Additional Species and Challenges

Several vehicles go by when I'm out on duty and we discover some casualties as a result – no amphibians, but three squashed newts. We spot one living newt as well, and the teenager is especially excited to see a daddy longlegs, which moves in his palms. Yet despite the team's best efforts to let me see a toad, the local population has obviously gone dormant for the winter. It seems that I couldn't have found any better success elsewhere in the nation – 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

One email I get from a different helper, who has generously made the effort to look for toads in a noted location, considered 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 group plans to assist around ten thousand mature amphibians over the street.

Impact and Limitations

How much of a difference can these groups truly achieve? "The fact that people are performing this regularly on chilly, wet and miserable 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.

Additional Threats

The climate crisis has resulted in extended spells of dry weather, which create the poor environment for some of the animals that toads eat, such as worms and slugs, while warmer ponds have led to an rise of blue-green algae, which can be toxic to toads. Warmer cold seasons also lead toads to wake up from their hibernation more frequently, interfering with the resource preservation crucial to their existence. Habitat destruction – 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 wildlife," however "There is a big value in just their presence." But toads do have an significant part in the food chain, consuming pretty much any invertebrates or small animals they can swallow and in turn feeding a variety of predators, such as hedgehogs and otters. Improving conditions for toads – such as 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 specialist. Legends and tales around toads go back {centuries|hundred
