It is a Friday night at half past seven, but instead of going out or relaxing at home, I've taken 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 native amphibian community.

A Worrying Decline in Numbers

The Bufo bufo is growing more uncommon. A latest study conducted by an wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Observing a creature that has been a stalwart of the UK landscape in decrease is described as "worrying" by experts. Toads "don't require very particular environments" and "should be able to live quite well in the majority of habitats in the UK," so if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

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

The Threat from Traffic

Though the research didn't cover the reasons for the drop, traffic certainly plays a part. Estimates indicate that 20 tons of toads are crushed on UK roads every year – in other words, hundreds of thousands. Unlike frogs, which would probably be content to mate "with just a small container," toads prefer big bodies of water. Their ability to remain away from water for longer than frogs means they can journey farther to find them – sometimes hundreds of metres. They usually follow their traditional paths – it's typical for mature amphibians to return to their birth pond to mate.

Migration Habits

Fittingly, the first toads begin their quest for a partner around February 14th, but others travel as far as April, until it gets dark and travelling after sunset. During that period, toads start moving from wherever they have been hibernating "almost simultaneously."

One volunteer, who grew up in the region and has been trying to protect its amphibians 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 road, they could all get run over, and that mating period would never happen – stopping a next generation of toads from being born.

Toad Patrols Throughout the United Kingdom

Finding many of toad carcasses on local roads "resonates deeply with people," and has led to the creation of rescue teams throughout the UK – 274 groups are officially listed with a countrywide program. These groups collect toads and carry them across roads in buckets, as well as counting the quantity 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 implies they can miss groups of toadlets, which, having been eggs and then tadpoles, exit their water habitats over an unpredictable schedule in late summer. Because of their size – just a couple of cm wide – "they can get obliterated by car traffic." And as being hit "essentially crushes them," it's harder to collect information on them. At least when mature amphibians are lost, their remains can be tallied.

Year-Round Work

Unlike most patrols, a specific volunteer group, who are in their eighth year of operating, go out year-round – not every night, but whenever weather are warm and wet, or if a member has reported about a toad sighting in their group chat. When I request to accompany them on duty, they admit it is "not ideal conditions" – toad hibernation season has started and it's been a arid period – but a few of the helpers gamely agree to patrol their route with me and see what we can find. "If anyone can locate any toads tonight, those two will spot one," says the group coordinator, pointing to her teenage child 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.

Family Participation

The family duo joined the patrol a year and a half ago. The teenager adores all things wildlife and has an goal to become a environmentalist, so his parent started to look for activities they could do together to protect local wildlife. Now she loves it as much as he does, the middle-aged small business owner tells me – so when the group was looking for a fresh coordinator lately, she decided to step up.

The youth, too, has played an important role in the group. A clip he created, urging the municipal authority to close a road through a nature reserve during migration season, influenced the outcome the group's way. After a year of campaigning, the council 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 Difficulties

A few vehicles go past when I'm out on duty and we discover some victims as a consequence – no amphibians, but several crushed salamanders. We spot one living newt as well, and the youngster is particularly pleased to see a harvestman, which dances in his palms. Yet despite the group's hardest attempts to let me see a toad, the local population has clearly gone dormant for the colder months. It appears that I wouldn't have had any more luck elsewhere in the country – all the patrol groups I reach out to clarify that it's near-impossible at this season.

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 group in the UK, reaches me with the subject line: "None found." However, in late winter, he informs me, the group expects to help approximately 10,000 adult toads over the street.

Effectiveness and Limitations

What level of impact can these groups truly achieve? "The fact that people are performing this consistently on cold, damp and unpleasant evenings is remarkable," says an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – not least because vehicles is not the only threat.

Additional Threats

The global warming has meant extended spells of dry weather, which create the wrong conditions for some of the animals that toads consume, such as worms and slugs, while warmer ponds have caused an increase of toxic plants, which can be harmful to toads. Milder winters also lead toads to emerge from their hibernation more often, interfering with the energy conservation vital to their life cycle. Habitat destruction – especially the loss of big water bodies – is an additional threat.

Researchers are "often concerned about overemphasizing practical benefits on biodiversity," however "It's important in just having these animals around." But toads play an significant part in the ecosystem, consuming pretty much any small creatures or tiny organisms they can swallow and in turn sustaining a variety of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – ie building water habitats, conserving woodland and installing toad tunnels – "we'll improve them for a wide range of additional wildlife."

Cultural Importance

An additional motive to work to preserve toads around is their "historical significance," notes an specialist. Myths and folklore around toads date back {centuries|hundred
