It's a Friday evening at half past seven, but instead of heading to the pub or watching a film, I've caught a train to a market town in the countryside to meet up with local helpers from a amphibian rescue group. These committed people sacrifice their nights to safeguard the local toad population.

An Alarming Drop in Numbers

The common toad is becoming increasingly rare. A latest research led by an wildlife conservation group revealed that the UK toad population have dropped by half since the mid-1980s. Observing a creature that has been a fixture of the UK landscape in decline is described as "worrying" by experts. 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 kind of suggests that things are not as they should be."

The Threat from Traffic

Though the study didn't examine the causes for the decline, traffic certainly plays a part. Calculations indicate that 20 tons of toads are killed on UK roads annually – that is, several hundred thousand. In contrast to frogs, which would probably be happy to mate "if you left out a bucket of water," toads favor large ponds. Their capacity to remain away from water for longer than frogs means they can travel further to find them – often hundreds of metres. They usually follow their ancestral migration routes – it's typical for adult toads to go back to their natal pond to mate.

Breeding Habits

Fittingly, the initial amphibians begin their quest for a mate around Valentine's day, but others travel as late as April, waiting until it gets night and travelling through the night. During that time, toads begin migrating from wherever they have been overwintering "almost simultaneously."

A local helper, who grew up in the area and has been working to save its amphibians since he was a boy, explains that "They've got just one focus: to go and have an orgy." If their path crosses a road, they could all get run over, and that mating period would be lost – preventing a new generation of toads from being produced.

Rescue Groups Across the UK

Finding hundreds of dead toads on local roads "resonates deeply with people," and has led to the creation of rescue teams throughout the UK – hundreds of organizations are currently registered with a countrywide program. These groups pick up toads and transport them over streets in containers, as well as recording the number of toads they encounter and advocating for other protection measures, 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 miss groups of toadlets, which, having existed as spawn and then juveniles, leave their water habitats over an irregular timetable in late summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "basically turns them into mush," it's harder to get data on them. At least when adult toads are lost, their remains can be tallied.

Annual Efforts

Unlike many groups, one local team, who are in their eighth year of functioning, go out throughout the year – not every night, but whenever conditions 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 admit it is "not a toady night" – winter dormancy has begun and it's been a dry day – 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 find any toads tonight, those two will find one," says the group coordinator, indicating her 14-year-old son and the experienced member. After for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to check under some logs.

Family Involvement

The family duo joined the patrol a while back. The teenager loves all things nature-related and has an goal to become a conservationist, so his mother started to look for activities they could do jointly to protect native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the team was looking for a new manager lately, she volunteered for the role.

The teenager, too, has been instrumental in the organization. A video he created, imploring the local council to block a road through a nature reserve during breeding time, influenced the outcome the team's way. After a twelve months of campaigning, the council agreed to an "access-only" restriction between 5pm and 5am from February through to spring. The majority of motorists respected and avoided the route.

Additional Species and Difficulties

A few cars go past when I'm out on patrol and we find some victims as a result – no amphibians, but several crushed salamanders. We see one living newt 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 hardest attempts to show me a toad, the native community has clearly settled down for the colder months. 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 near-impossible at this time of year.

One email I get from a different helper, who has kindly taken the trouble to look for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, reaches me with the title: "None found." However, in late winter, he tells me, the group plans to assist around ten thousand mature amphibians across the road.

Impact and Limitations

How much of a difference can these organizations actually make? "The reality that volunteers are performing this regularly on cold, damp and unpleasant late nights is remarkable," says an researcher. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since vehicles is not the only threat.

Additional Threats

The climate crisis has resulted in extended spells of drought, which cause the wrong conditions for some of the animals that toads eat, such as worms and slugs, while warmer ponds have caused an rise of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to emerge from their dormancy more often, disrupting the resource preservation crucial to their life cycle. Habitat destruction – particularly the loss of big water bodies – is another menace.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," however "There is a big value in just having these animals around." But toads play an significant part in the ecosystem, consuming almost any small creatures or small animals they can swallow and in turn sustaining a variety of birds and mammals, such as wildlife. Improving conditions for toads – ie building water habitats, protecting forests and installing toad tunnels – "we'll improve them for a wide range of other species."

Historical Significance

An additional motive to try to keep toads present is their "historical significance," notes an expert. Legends and tales around toads go back {centuries|hundred
