It is Friday evening at 7:30, but instead of going out or relaxing at home, I've caught a train to a town in the countryside to meet up with volunteers from a toad patrol. These committed people give up their evenings to safeguard the native amphibian community.

An Alarming Decline in Population

The Bufo bufo is becoming increasingly uncommon. A latest research conducted by an wildlife conservation group showed that the UK toad population have dropped by half since the mid-1980s. Seeing a creature that has been a fixture of the UK landscape in decline is described as "worrying" by experts. Toads "don't need very particular environments" and "should be able to live successfully in most of areas in the UK," so if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

The Danger from Traffic

Though the research didn't examine the causes for the decline, cars certainly plays a part. Estimates suggest that 20 tonnes of toads are crushed on UK roads annually – in other words, hundreds of thousands. In contrast to frogs, which might be content to mate "if you left out a bucket of water," toads favor large ponds. Their capacity to stay out of water for longer than frogs means they can journey farther to find them – sometimes long distances. They tend to follow their ancestral migration routes – it's typical for adult toads to return to their birth pond to mate.

Migration Patterns

Fittingly, the first toads start their journey for a mate around Valentine's day, but some move as late as April, until it gets night and travelling after sunset. During that period, toads start moving from where they have been hibernating "almost simultaneously."

A local helper, 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 be killed by traffic, and that mating period would never happen – stopping a next generation of toads from being produced.

Rescue Groups Throughout the UK

Finding hundreds of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the creation of rescue teams across the UK – 274 groups are currently registered with a national initiative. These teams collect toads and carry them across roads in containers, as well as recording the number of toads they encounter and lobbying for other safety solutions, such as blocked roads and amphibian passages.

Patrols usually work during the migration season, when amphibian movements are frequent. However, this means they can overlook groups of toadlets, which, having existed as eggs and then tadpoles, leave their water habitats over an irregular timetable in late summer. Because of their size – just a couple of cm wide – "they are destroyed by car traffic." And as being run over "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are lost, their remains can be counted.

Year-Round Efforts

Unlike many groups, a specific volunteer group, who are in their eighth season of operating, go out year-round – not nightly, but whenever conditions are warm and wet, or if someone has reported about a toad sighting in their group chat. When I ask to join them on patrol, they concede it is "not ideal conditions" – winter dormancy has started and it's been a dry day – but a few of the volunteers willingly accept to walk up and down their route with me and search for any toads. "Should anyone can locate 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 inspect beneath some wood.

Community Involvement

The family duo became part of the patrol a year and a half ago. The youngster adores all things wildlife and has an goal to become a conservationist, so his mother started to look for activities they could do together to help local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur tells me – so when the group was seeking a fresh coordinator recently, she volunteered for the role.

The youth, too, has been instrumental in the organization. A clip he created, urging the municipal authority to block a road through a nature reserve during breeding time, swung the decision the group's way. After a twelve months of lobbying, the authority approved an "access-only" rule between evening and morning from February through to spring. The majority of motorists duly avoided the route.

Additional Species and Challenges

Several cars go past when I'm out on patrol and we find some casualties as a consequence – no amphibians, but three squashed newts. We spot one living newt as well, and the teenager is particularly pleased to see a harvestman, which dances in his hands. Yet despite the group's best efforts to show me a toad, the local population has clearly gone dormant for the winter. It appears that I wouldn't have had any more luck anywhere else in the country – all the rescue teams I contact clarify 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 kindly taken the trouble to check for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the subject line: "None found." However, in late winter, he informs me, the group plans to assist around 10,000 adult toads across the road.

Effectiveness and Limitations

What level of impact can these organizations actually make? "The fact that people are performing this regularly on chilly, wet and miserable late nights is quite extraordinary," says an researcher. "That's something that very much should be celebrated." However, while toad patrols are able to slow the decline, they can't stop it completely – partly since traffic is not the only threat.

Additional Threats

The climate crisis has resulted in extended spells of drought, which cause the poor environment for some of the animals that toads consume, such as invertebrates, while warmer ponds have led to an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also cause toads to emerge from their hibernation more often, interfering with the resource preservation crucial to their life cycle. Habitat destruction – especially the loss of large ponds – is another menace.

Experts are "often concerned about putting too much of a utilitarian spin on biodiversity," but "There is a big value in just their presence." But toads play an important role in the food chain, consuming pretty much any invertebrates or small animals they can swallow and in turn sustaining a number of birds and mammals, such as wildlife. Improving conditions for toads – ie building water habitats, conserving woodland and installing amphibian passages – "benefits for a wide range of other species."

Historical Importance

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