It's Friday evening at half past seven, but instead of going out or watching a film, I've taken a train to a town in the countryside to join volunteers from a amphibian rescue group. These committed people sacrifice their evenings to safeguard the local toad population.

An Alarming Drop in Numbers

The common toad is growing more rare. A latest research led by an amphibian and reptile charity showed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decrease is described as "concerning" by researchers. Toads "don't require very specific conditions" and "should be able to live successfully in most of habitats in Britain," so if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

The UK toad population has almost halved since 1985

The Danger from Traffic

Though the study didn't examine the reasons for the decline, cars is a major factor. Calculations suggest that 20 tonnes of toads are killed on UK roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be content to mate "with just a small container," toads prefer large ponds. Their capacity to stay out of water for longer than frogs allows they can travel further to reach them – sometimes hundreds of metres. They usually follow their ancestral migration routes – it's common for mature amphibians to return to their natal pond to mate.

Breeding Patterns

Fittingly, the first toads start their journey for a partner around February 14th, but others travel as far as spring, waiting until it gets night and moving through the night. During that time, toads start moving from where they have been hibernating "all pretty much at the same time."

One volunteer, who was raised in the area and has been working to save its toad population since he was a boy, explains that "They've got just one focus: to go and have an orgy." If their path crosses a road, they could be killed by traffic, and that mating period would never happen – stopping a new generation of toads from being born.

Toad Patrols Throughout the UK

Seeing many of dead toads on nearby streets "resonates deeply with people," and has led to the formation of rescue teams across the UK – 274 groups are officially listed with a countrywide program. These teams pick up toads and transport them over streets in containers, as well as counting the number of toads they encounter and advocating for other safety solutions, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the breeding period, when toad crossings are frequent. However, this implies they can miss numbers of toadlets, which, having existed as eggs and then juveniles, exit their ponds over an irregular timetable in late summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by car traffic." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are lost, their carcasses can be tallied.

Year-Round Work

Unlike most patrols, one local team, who are in their eighth year of operating, go out year-round – not nightly, but when conditions are warm and wet, or if someone has reported about a amphibian spotting in their messaging app. When I request to accompany them on patrol, they admit it is "not a toady night" – winter dormancy 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. "Should anyone can locate any toads tonight, that pair will spot one," says the group coordinator, indicating 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 wire barrier to check under some logs.

Community Involvement

The family duo 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 parent started to search for things they could do together to help local wildlife. Now she enjoys it as much as he does, the middle-aged entrepreneur explains – so when the team was seeking a fresh coordinator lately, she decided to step up.

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

Additional Species and Difficulties

A few cars go past when I'm out on patrol and we discover some victims as a result – no toads, but three squashed newts. We see 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 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 rescue teams I contact explain that it's near-impossible at this time of year.

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

A message I get from a different helper, who has generously taken the trouble to look for toads in a noted location, considered the largest accurately monitored toad population in the UK, reaches me with the title: "None found." However, in late winter, he tells me, the group expects to help around 10,000 adult toads over the street.

Impact and Limitations

How much of a difference can these groups actually make? "The fact that people are doing this regularly on chilly, wet and miserable late nights is quite extraordinary," notes an expert. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they can't stop it completely – not least because vehicles 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 creatures that toads eat, such as invertebrates, while warmer ponds have led to an increase of blue-green algae, which can be harmful to toads. Milder winters also lead toads to emerge from their hibernation more frequently, interfering with the energy conservation vital to their life cycle. Loss of environment – particularly the disappearance of big water bodies – is another menace.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," but "It's important in just their presence." But toads do have an significant part in the food chain, consuming almost any invertebrates or small animals they can swallow and in turn feeding a variety of birds and mammals, such as wildlife. Improving conditions for toads – ie building water habitats, conserving woodland and constructing amphibian passages – "we'll improve them for a wide range of additional wildlife."

Cultural Significance

Another reason to work to preserve toads present is their "important cultural value," adds an expert. Legends and tales around toads go back {centuries|hundred
