It is Friday evening at half past seven, but rather than going out or relaxing at home, I've taken a train to a market town in Wiltshire to join volunteers from a amphibian rescue group. These committed people sacrifice their evenings to safeguard the native amphibian community.

An Alarming Drop in Numbers

The Bufo bufo is growing more uncommon. A recent study led by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since 1985. Seeing a species that has been a stalwart of the UK landscape in decline is labeled "concerning" by researchers. 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 struggling to persist, "it indicates that the ecosystem is unbalanced."

The Danger from Traffic

Though the research didn't cover the causes for the decline, traffic is a major factor. Estimates suggest that 20 tons of toads are crushed on British roads every year – that is, hundreds of thousands. In contrast to frogs, which might be happy to mate "if you left out a small container," toads prefer large ponds. Their capacity to remain away from water for more time than frogs allows they can travel further to find them – sometimes hundreds of metres. They tend to follow their traditional paths – it's typical for mature amphibians to return to their birth pond to mate.

Breeding Habits

Fittingly, the initial amphibians begin their quest for a mate around Valentine's day, but others travel as far as spring, waiting until it gets dark and travelling after sunset. During that time, toads start moving from where they have been overwintering "all pretty much at the same time."

A local helper, who was raised in the region and has been trying to protect its amphibians since he was a child, notes that "They've got just one focus: to go and mate." If their path crosses a street, they could all get run over, and that mating period would never happen – stopping a next generation of toads from being produced.

Toad Patrols Across the United Kingdom

Finding hundreds of dead toads on nearby streets "resonates deeply with people," and has resulted in the formation of toad patrols throughout the UK – hundreds of organizations are currently registered with a countrywide program. These groups pick up toads and transport them across roads in buckets, as well as counting the number of toads they find and advocating for other safety solutions, such as blocked roads and amphibian passages.

Volunteers tend to operate during the migration season, when toad crossings are more regular. However, this means they can overlook groups of young toads, which, having existed as spawn and then tadpoles, leave their water habitats over an unpredictable schedule in late summer. Because of their small stature – just a couple of cm wide – "they are destroyed by vehicles." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when mature amphibians are lost, their carcasses can be counted.

Year-Round Work

Unlike many groups, one local team, who are in their eighth year of functioning, go out throughout the year – not nightly, but when weather are warm and wet, or if someone has posted about a amphibian spotting in their group chat. When I ask to join them on duty, they admit it is "not a toady night" – winter dormancy has started and it's been a dry day – but several of the volunteers willingly accept to patrol their area with me and see what we can find. "Should anyone can find any toads tonight, that pair will spot one," says the patrol manager, indicating her 14-year-old son and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to check under some logs.

Community Participation

The mother and son joined the patrol a while back. The teenager adores all things nature-related and has an goal to become a environmentalist, so his mother started to look for things they could do together to protect local wildlife. Now she loves it as much as he does, the middle-aged small business owner explains – so when the group was looking for a fresh coordinator recently, she decided to step up.

The youth, too, has been instrumental in the organization. A video he created, urging the local council to close a street through a protected area during migration season, swung the decision the group's way. After a twelve months of lobbying, the authority approved an "restricted access" rule between evening and morning from February through to April. Most drivers respected and avoided the road.

Other Wildlife and Difficulties

A few vehicles go by when I'm out on duty and we find some victims as a result – no toads, but several crushed salamanders. We spot one living newt as well, and the teenager is particularly pleased to see a harvestman, which moves in his hands. Yet despite the group's hardest attempts to show me a toad, the native community has clearly settled down for the colder months. 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 near-impossible at this time of year.

One email I get from another volunteer, who has generously taken the trouble to look for toads in a noted location, considered the biggest tracked toad group in the UK, arrives in my inbox with the subject line: "No toads." However, in February and March, he informs me, the group plans to assist approximately ten thousand adult toads across the road.

Impact and Limitations

What level of impact can these organizations truly achieve? "The reality that people are performing this regularly on cold, damp and unpleasant evenings is quite extraordinary," notes an researcher. "That's something that very much deserves recognition." However, while rescue teams are able to reduce the drop, they can't stop it completely – not least because vehicles is not the only threat.

Other Dangers

The global warming has meant extended spells of drought, which create the poor environment for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused an increase of blue-green algae, which can be toxic to toads. Milder winters also cause toads to emerge from their dormancy more often, interfering with the resource preservation vital to their existence. Loss of environment – especially the disappearance of big water bodies – is an additional threat.

Experts are "always a bit worried about putting too much of a utilitarian spin on wildlife," however "There is a big value in just having these animals around." But toads play an important role in the food chain, eating pretty much any small creatures or small animals they can fit in their mouths and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Enhancing situations for toads – such as creating more ponds, protecting forests and constructing toad tunnels – "we'll improve them for a wide range of other species."

Historical Significance

An additional motive to work to preserve toads around is their "important cultural value," notes an expert. Legends and tales around toads date back {centuries|hundred
