It is Friday evening at 7:30, but instead of going out or relaxing at home, I've taken a train to a market town in Wiltshire to meet up with volunteers from a amphibian rescue group. These committed people sacrifice their evenings to safeguard the local toad population.

A Worrying Decline in Population

The Bufo bufo is growing more rare. A recent study led by an wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Observing a species that has been a fixture of the British countryside in decrease is described as "worrying" by experts. Toads "don't require very specific conditions" and "ought to live successfully in the majority of areas in the UK," meaning if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

Since 1985, Britain's toad numbers have nearly been cut in half

The Danger from Roads

Though the research didn't cover the reasons for the decline, cars certainly plays a part. Calculations indicate that 20 tonnes of toads are crushed on British roads annually – that is, several hundred thousand. Unlike frogs, which might be happy to mate "with just a small container," toads favor large ponds. Their ability to stay out of water for more time than frogs allows they can travel further to find them – often long distances. They tend to follow their ancestral migration routes – it's common for adult toads to go back to their birth pond to mate.

Migration Patterns

Fittingly, the initial amphibians start their journey for a partner around Valentine's day, but others travel as far as April, until it gets dark and travelling after sunset. During that time, toads start moving from where they have been hibernating "almost simultaneously."

A local helper, who grew up in the region and has been working to save its toad population since he was a boy, notes that "Their sole purpose: to go and have an orgy." If their route happens to a street, they could all get run over, and that breeding season would never happen – stopping a new generation of toads from being produced.

Toad Patrols Throughout the UK

Seeing many of dead toads on local roads "inherently strikes a chord with people," and has resulted in the creation of toad patrols across the UK – 274 groups are currently registered with a national initiative. These teams pick up toads and transport them across roads in containers, as well as counting the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and amphibian passages.

Patrols usually work during the migration season, when toad crossings are more regular. However, this implies they can miss groups of toadlets, which, having existed as spawn and then tadpoles, exit their water habitats over an unpredictable schedule in the end of summer. Because of their size – just one or two centimetres wide – "they are destroyed by car traffic." And as being run over "essentially crushes them," it's harder to get data on them. At least when adult toads are killed, their remains can be counted.

Annual Efforts

In contrast to many groups, a specific volunteer group, who are in their eighth year of operating, go out throughout the year – not nightly, but when conditions are damp, or if someone has posted about a amphibian spotting in their group chat. When I ask to join them on patrol, they admit it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but a few of the volunteers willingly accept to walk up and down their area with me and see what we can find. "If anyone can find any toads tonight, those two will find one," says the patrol manager, pointing to her teenage child and the longtime volunteer. We've been out for 120 minutes without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some wood.

Family Participation

The mother and son joined the group a year and a half ago. The teenager adores all things wildlife and has an goal to become a environmentalist, so his mother started to search for activities they could do together to help native animals. Now she loves it as much as he does, the 41-year-old small business owner explains – so when the group was looking for a fresh coordinator lately, she decided to step up.

The youth, too, has been instrumental in the group. A video he made, imploring the local council to block a road through a protected area during migration season, swung the decision the team's way. After a year of lobbying, the council approved an "restricted access" rule between 5pm and 5am from late winter through to spring. The majority of motorists duly avoided the route.

Other Wildlife and Challenges

Several vehicles go by when I'm out on patrol and we find some casualties as a consequence – no toads, but several crushed salamanders. We spot one live amphibian as well, and the youngster is particularly pleased to see a harvestman, which moves in his palms. Yet despite the team's best efforts to let me see a toad, the native community has clearly settled down for the colder months. It seems that I couldn't have found any more luck anywhere else in the country – all the rescue teams I reach out to explain that it's very difficult at this time of year.

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

One email I get from a different helper, who has generously taken the trouble to look for toads in a famous site, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the title: "None found." However, in February and March, he tells me, the group plans to assist approximately ten thousand adult toads over the street.

Impact and Challenges

What level of impact can these groups truly achieve? "The fact that people are doing this regularly on cold, damp and unpleasant evenings is remarkable," says an researcher. "That's something that very much deserves recognition." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – 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 wrong conditions for some of the animals that toads eat, such as worms and slugs, while higher water temperatures have caused an rise of blue-green algae, which can be harmful to toads. Milder winters also cause toads to emerge from their hibernation more frequently, disrupting the resource preservation crucial to their life cycle. Habitat destruction – particularly the loss of large ponds – is another menace.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," however "It's important in just their presence." But toads play an significant part in the ecosystem, consuming almost any invertebrates or small animals they can fit in their mouths and in turn feeding a variety of birds and mammals, such as wildlife. Enhancing situations for toads – such as building water habitats, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Historical Significance

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