It's Friday evening at half past seven, but rather than heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to join local helpers from a amphibian rescue group. These committed people give up their nights to protect the native amphibian community.

An Alarming Drop in Population

The common toad is becoming increasingly uncommon. A recent research led by an amphibian and reptile charity revealed that the UK toad population have almost halved since the mid-1980s. Observing a creature that has been a fixture of the UK landscape in decline is labeled "concerning" by experts. Toads "don't require very particular environments" and "should be able to live quite well in the majority of areas in Britain," meaning if even they are struggling to persist, "it indicates that things are not as they should be."

The Danger from Traffic

Though the research didn't cover the causes for the decline, cars certainly plays a part. Calculations indicate that 20 tons of toads are killed 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 prefer large ponds. Their capacity to stay out of water for longer than frogs means they can travel further to find them – sometimes 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.

Migration Patterns

Fittingly, the first toads start their journey for a mate around Valentine's day, but others travel as far as spring, until it gets night and moving after sunset. During that period, toads start moving from where they have been overwintering "almost simultaneously."

One volunteer, who was raised in the area and has been working to save its toad population since he was a child, notes that "They've got just one focus: to go and mate." If their path happens to a street, they could be killed by traffic, and that breeding season would never happen – preventing a next generation of toads from being produced.

Toad Patrols Across the UK

Finding many of toad carcasses on local roads "inherently strikes a chord with people," and has led to the creation of toad patrols across the UK – 274 groups are officially listed with a countrywide program. These teams collect toads and transport them over streets in buckets, as well as counting the number of toads they find and advocating for other protection measures, such as blocked roads and amphibian passages.

Patrols tend to operate during the breeding period, when amphibian movements are frequent. However, this means they can miss numbers of young toads, which, having been spawn and then tadpoles, leave their ponds over an unpredictable schedule 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 get data on them. At least when mature amphibians are lost, their carcasses can be counted.

Year-Round Work

In contrast to many groups, one local team, who are in their eighth season of functioning, go out year-round – not nightly, but when conditions are damp, or if someone has reported about a amphibian spotting in their messaging app. When I ask to join them on patrol, they admit it is "not a toady night" – winter dormancy has started and it's been a arid period – but several of the helpers willingly accept to patrol their area with me and see what we can find. "If anyone can locate any toads tonight, those two will spot one," says the patrol manager, pointing to her 14-year-old son and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to inspect beneath some wood.

Community Involvement

The family duo became part of the patrol a year and a half ago. The teenager loves all things wildlife and has an ambition to become a conservationist, so his mother started to look for things they could do together to help native animals. Now she enjoys it as much as he does, the 41-year-old small business owner tells me – so when the group was seeking a new manager recently, she decided to step up.

The teenager, too, has played an important role in the organization. A video he made, imploring the municipal authority to block a street through a protected area during breeding time, influenced the outcome the group's way. After a twelve months of lobbying, the authority agreed to an "restricted access" restriction between 5pm and 5am from February through to spring. The majority of motorists duly avoided the route.

Additional Species and Difficulties

A few cars go by 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 youngster is especially excited to see a harvestman, which moves in his palms. Yet in spite of the group's hardest attempts to show me a toad, the native community has clearly gone dormant for the winter. It appears that I couldn't have found any better success anywhere else in the country – all the rescue teams I reach out to explain that it's near-impossible at this season.

The group expects to help approximately 10,000 adult toads across the road

A message I get from another volunteer, who has kindly taken the trouble to look for toads in a famous site, considered the largest accurately monitored toad population in the UK, reaches me with the subject line: "None found." However, in February and March, he informs me, the team expects to help approximately 10,000 mature amphibians across the road.

Effectiveness and Limitations

What level of impact can these organizations actually make? "The reality that volunteers are performing this regularly on cold, damp and unpleasant late nights is quite extraordinary," says an researcher. "That's something that very much should be celebrated." However, while toad patrols are able to reduce the drop, they can't stop it completely – partly since vehicles is just one danger.

Additional Threats

The climate crisis has resulted in extended spells of drought, which create the wrong conditions for some of the creatures that toads consume, such as worms and slugs, 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 emerge from their hibernation more often, interfering with the energy conservation vital to their life cycle. Loss of environment – especially the loss of big water bodies – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on wildlife," however "It's important in just having these animals around." But toads play an significant part in the food chain, consuming pretty much any invertebrates or small animals they can swallow and in turn sustaining a number of predators, such as wildlife. Improving conditions for toads – ie creating more ponds, protecting forests and constructing amphibian passages – "we'll improve them for a wide range of other species."

Historical Importance

Another reason to try to keep toads present is their "historical significance," notes an specialist. Legends and tales around toads date back {centuries|hundred
