It's Friday evening at half past seven, but rather than going out or relaxing at home, I've caught a train to a market town in the countryside to meet up with volunteers from a amphibian rescue group. These committed people sacrifice their nights to safeguard the local toad population.

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. Observing a species that has been a fixture of the British countryside in decrease is described as "concerning" by experts. Toads "don't need very specific conditions" and "should be able to live successfully in most of habitats in the UK," so if even they are not managing to survive, "it indicates that things are not as they should be."

The Danger from Traffic

Though the study didn't examine the causes for the drop, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are crushed on British roads annually – 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 allows they can journey farther to find them – often long distances. They tend to follow their ancestral migration routes – it's typical for adult toads to return to their natal pond to mate.

Breeding Habits

Appropriately enough, the first toads begin their quest for a mate around Valentine's day, but some move as late as April, until it gets dark and travelling after sunset. During that period, toads begin migrating from where they have been hibernating "all pretty much at the same time."

One volunteer, who grew up in the region and has been trying to protect its toad population since he was a child, explains that "Their sole purpose: to go and mate." If their route happens to a road, they could be killed by traffic, and that breeding season would be lost – stopping a new generation of toads from being produced.

Rescue Groups Throughout the United Kingdom

Finding many of toad carcasses on local roads "inherently strikes a chord with people," and has led to the formation of toad patrols across the UK – hundreds of organizations are officially listed with a countrywide program. These teams collect toads and carry them over streets in containers, as well as counting the number of toads they encounter and lobbying for other protection measures, such as road closures and amphibian passages.

Volunteers usually work during the breeding period, when toad crossings are frequent. However, this implies they can overlook groups of toadlets, which, having existed as spawn and then tadpoles, exit their ponds over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they are destroyed by car traffic." And as being hit "basically turns them into mush," it's more difficult to get data on them. At least when mature amphibians are killed, their remains can be counted.

Annual Efforts

In contrast to most patrols, a specific volunteer group, 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 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 started and it's been a arid period – but several of the volunteers willingly accept to walk up and down their route with me and see what we can find. "If anyone can find any toads tonight, those two will spot one," says the group coordinator, pointing to her 14-year-old son and the longtime volunteer. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to check under some wood.

Community Participation

The family duo became part of the group a while back. The youngster adores all things nature-related and has an goal to become a conservationist, so his parent started to look for activities they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner explains – so when the team was looking for a new manager recently, she volunteered for the role.

The teenager, too, has played an important role in the organization. A video he made, urging the local council to block a road 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" restriction between 5pm and 5am from February through to spring. The majority of motorists duly avoided the route.

Other Wildlife and Challenges

Several vehicles go by when I'm out on duty and we find some casualties as a result – no toads, but several crushed salamanders. We spot one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which moves in his palms. Yet in spite of the team's best efforts to show me a toad, the local population has obviously settled down for the colder months. It seems that I wouldn't have had any more luck anywhere else in the country – all the patrol groups I contact clarify that it's near-impossible at this season.

A message I receive from a different helper, who has generously made the effort to look for toads in a famous site, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "None found." However, in late winter, he tells me, the team plans to assist around 10,000 adult toads over the street.

Impact and Limitations

How much of a difference can these groups truly achieve? "The fact that people are doing this regularly on cold, damp and unpleasant evenings is remarkable," notes an expert. "That's something that very much should be celebrated." However, while toad patrols are able to slow the decline, they can't stop it completely – not least because vehicles is not the only threat.

Other Dangers

The climate crisis has resulted in extended spells of dry weather, which create the poor environment for some of the animals that toads consume, such as invertebrates, while warmer ponds have caused an increase of blue-green algae, which can be harmful to toads. Milder winters also cause toads to emerge from their hibernation more often, disrupting the energy conservation vital to their life cycle. Loss of environment – especially the disappearance of big water bodies – is another menace.

Experts are "always a bit worried about overemphasizing practical benefits on biodiversity," but "There is a big value in just having these animals around." But toads play an significant part in the food chain, consuming almost any invertebrates or small animals they can fit in their mouths and in turn sustaining a variety of birds and mammals, such as wildlife. Improving situations for toads – such as building water habitats, protecting forests and constructing toad tunnels – "benefits for a wide range of additional wildlife."

Historical Significance

An additional motive to work to preserve toads present is their "important cultural value," notes an expert. Myths and folklore around toads go back {centuries|hundred
