It is Friday night at 7:30, but instead of heading to the pub or watching a film, I've caught a train to a market town in the countryside to join volunteers from a amphibian rescue group. These committed people sacrifice their evenings to safeguard the native amphibian community.

An Alarming Decline in Population

The Bufo bufo is growing more uncommon. A recent study conducted by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decrease is described as "worrying" by experts. Toads "don't need very specific conditions" and "should be able to live quite well in most of areas in Britain," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

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

The Danger from Roads

Though the study didn't examine the reasons for the decline, cars is a major factor. Calculations suggest that 20 tonnes of toads are crushed on British roads annually – that is, several hundred thousand. In contrast to frogs, which might be content to mate "with just a small container," toads favor big bodies of water. Their ability to remain away from water for longer than frogs means they can journey farther to reach them – sometimes long distances. They usually stick to their ancestral migration routes – it's typical for mature amphibians to go back to their birth pond to mate.

Breeding Habits

Appropriately enough, the first toads begin their quest for a partner around February 14th, but others travel as far as April, until it gets night and travelling through the night. During that period, toads begin migrating from where they have been overwintering "all pretty much at the same time."

One volunteer, who grew up in the area and has been working to save its amphibians since he was a child, explains that "Their sole purpose: to go and mate." If their path happens to a street, they could be killed by traffic, and that mating period would be lost – preventing a next generation of toads from being produced.

Toad Patrols Throughout the UK

Finding many of toad carcasses on local roads "resonates deeply with people," and has resulted in the creation of rescue teams across the UK – hundreds of organizations are officially listed with a national initiative. These teams 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 road closures and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when toad crossings are frequent. However, this implies they can overlook numbers of toadlets, which, having existed as eggs and then juveniles, leave their water habitats over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they are destroyed by vehicles." And as being hit "essentially crushes them," it's harder to get data on them. At least when adult toads are killed, their remains can be tallied.

Year-Round Work

In contrast to many groups, a specific volunteer group, who are in their eighth year of operating, go out year-round – not nightly, but when weather are warm and wet, or if a member has posted about a amphibian spotting in their messaging app. When I ask to join them on duty, they admit it is "not ideal conditions" – winter dormancy has begun and it's been a arid period – but a few of the volunteers gamely agree to patrol their route with me and search for any toads. "Should anyone can locate any toads tonight, those two will spot one," says the patrol manager, indicating her teenage child and the longtime volunteer. After for two hours without a single toad sighting, and now they have scaled a barbed wire fence to check under some wood.

Community Involvement

The mother and son joined the patrol a while back. The youngster loves all things nature-related and has an goal to become a environmentalist, so his parent started to look for activities they could do together to protect native animals. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the group was seeking a new manager lately, she decided to step up.

The youth, too, has been instrumental in the organization. A video he created, imploring the local council to block a street through a protected area during breeding time, influenced the outcome the group's way. After a twelve months of campaigning, the authority agreed to an "access-only" restriction between 5pm and 5am from February through to spring. Most drivers respected and avoided the road.

Other Wildlife and Difficulties

A few vehicles go past when I'm out on patrol and we find some casualties as a result – no amphibians, but three squashed newts. We see one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which dances 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 winter. It appears that I couldn't have found any better success elsewhere in the country – all the rescue teams I reach out to explain that it's near-impossible at this season.

The group expects to help approximately 10,000 adult toads across the road

A message I get from a different helper, who has generously made the effort to check for toads in a noted location, considered the biggest tracked toad population in the UK, reaches me with the subject line: "No toads." However, in February and March, he tells me, the team expects to help around ten thousand mature amphibians over the street.

Effectiveness and Limitations

What level of impact can these groups actually make? "The reality that people are doing this regularly on chilly, wet and miserable evenings is remarkable," says an expert. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because vehicles is not the only threat.

Additional Threats

The global warming has resulted in extended spells of drought, which cause the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have caused an increase of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to wake up from their dormancy more frequently, disrupting the energy conservation vital to their life cycle. Habitat destruction – especially the loss of large ponds – is another menace.

Researchers are "often concerned about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just having these animals around." But toads do have an important role in the ecosystem, consuming almost any invertebrates or tiny organisms they can swallow and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Enhancing situations for toads – ie creating more ponds, protecting forests and constructing amphibian passages – "benefits for a whole bunch of other species."

Historical Significance

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