It is a Friday night at half past seven, but instead of going out or relaxing at home, I've caught a train to a market town in Wiltshire to meet up with local helpers from a amphibian rescue group. These dedicated individuals give up their nights to safeguard the local toad population.

A Worrying Drop in Numbers

The common toad is becoming increasingly uncommon. A latest study conducted by an wildlife conservation group revealed that the British common toad numbers have dropped by half since 1985. Observing a species that has been a stalwart of the UK landscape in decline is described as "worrying" by researchers. Toads "don't require very particular environments" and "should be able to live successfully in the majority of areas in Britain," so if even they are not managing to survive, "it kind of suggests that things are not as they should be."

Toad populations across the UK have declined by almost 50% since the 1980s

The Danger from Roads

Though the study didn't cover the causes for the drop, cars certainly plays a part. Calculations indicate that 20 tonnes of toads are crushed on British roads annually – in other words, several hundred thousand. Unlike frogs, which would probably be happy to mate "with just a small container," toads favor big bodies of water. Their capacity to stay out of water for more time than frogs allows they can travel further to reach them – often hundreds of metres. They usually stick to their ancestral migration routes – it's common for mature amphibians to go back to their birth pond to mate.

Migration Patterns

Appropriately enough, the first toads begin their quest for a mate around Valentine's day, but others travel as far as spring, until it gets dark and moving through the night. During that time, toads start moving from wherever they have been hibernating "almost simultaneously."

A local helper, who grew up in the area and has been working to save its amphibians since he was a boy, notes that "Their sole purpose: to go and have an orgy." If their path happens to a road, they could be killed by traffic, and that mating period would never happen – stopping a next generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding hundreds of dead toads on nearby streets "resonates deeply with people," and has led to the creation of toad patrols throughout the UK – 274 groups are currently registered with a countrywide program. These groups collect toads and carry them over streets in buckets, as well as recording the quantity of toads they encounter and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this means they can overlook numbers of young toads, which, having been eggs and then tadpoles, leave their ponds over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are killed, their carcasses can be tallied.

Year-Round Work

In contrast to many groups, one local team, who are in their eighth season of operating, go out throughout the year – not nightly, but when weather are damp, or if someone has reported about a amphibian spotting in their group chat. When I request to accompany them on duty, they concede it is "not ideal conditions" – toad hibernation season has begun and it's been a arid period – but several of the volunteers willingly accept to patrol their area with me and search for any toads. "Should anyone can locate any toads tonight, those two will find 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 single toad sighting, and now they have scaled a barbed wire fence to inspect beneath some logs.

Community Participation

The mother and son joined the patrol a while back. The youngster adores all things wildlife and has an ambition to become a conservationist, so his parent started to look for activities they could do together to protect local wildlife. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the group was looking for a new manager lately, she volunteered for the role.

The teenager, too, has played an important role in the organization. A clip he created, imploring the local council to close a street through a protected area during migration season, influenced the outcome the group's way. After a year of campaigning, the authority approved an "access-only" rule between 5pm and 5am from February through to spring. Most drivers duly avoided the road.

Other Wildlife and Difficulties

A few vehicles go by when I'm out on duty and we discover some casualties as a result – no toads, but several crushed salamanders. We see one live amphibian as well, and the youngster is especially excited to see a harvestman, which dances in his hands. Yet in spite of the team's best efforts to show me a toad, the native community has clearly gone dormant for the winter. It appears that I couldn't have found any more luck elsewhere in the nation – all the patrol groups I reach out to explain that it's near-impossible at this time of year.

This team anticipates assisting around ten thousand mature toads over the street

One email I get from another volunteer, who has kindly made the effort to look for toads in a famous site, thought to be the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he tells me, the group plans to assist around 10,000 mature amphibians across the road.

Effectiveness and Challenges

What level of impact can these organizations actually make? "The reality that people are performing this consistently on chilly, wet and miserable evenings is quite extraordinary," says an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since traffic is just one danger.

Other Dangers

The global warming has meant longer periods of dry weather, which create the wrong conditions for some of the animals that toads eat, such as worms and slugs, while warmer ponds have led to an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also lead toads to wake up from their hibernation more often, interfering with the resource preservation vital to their life cycle. Loss of environment – particularly the disappearance of big water bodies – is an additional threat.

Researchers are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just having these animals around." But toads do have an important role in the ecosystem, consuming pretty much any small creatures or tiny organisms they can fit in their mouths and in turn feeding a number of birds and mammals, such as wildlife. Enhancing situations for toads – ie creating more ponds, conserving woodland and constructing toad tunnels – "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," adds an expert. Legends and tales around toads go back {centuries|hundred
