It is Friday evening at 7:30, but rather than heading to the pub or relaxing at home, I've caught a train to a market town in Wiltshire to join local helpers from a amphibian rescue group. These committed people give up their nights to protect the local toad population.

An Alarming Decline in Numbers

The common toad is becoming increasingly uncommon. A latest research conducted by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a creature that has been a fixture of the British countryside in decrease is described as "worrying" by experts. Toads "don't need very particular environments" and "should be able to live quite well in most of areas in Britain," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

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

The Threat from Roads

Though the study didn't cover the reasons for the drop, cars certainly plays a part. Calculations suggest that 20 tons of toads are killed on British roads every year – in other words, hundreds of thousands. In contrast to frogs, which would probably be happy to mate "if you left out a bucket of water," toads favor large ponds. Their capacity to remain away from water for longer than frogs allows they can travel further to reach them – often long distances. They tend to stick to their ancestral migration routes – it's typical for mature amphibians to go back to their natal pond to mate.

Migration Patterns

Fittingly, the first toads start their journey for a mate around February 14th, but some move as late as spring, waiting until it gets night and travelling through the night. During that period, toads begin migrating from where they have been hibernating "almost simultaneously."

A local helper, who grew up in the area and has been working to save its toad population since he was a boy, explains that "Their sole purpose: to go and have an orgy." If their path crosses a road, they could all get run over, and that breeding season would never happen – preventing a next generation of toads from being produced.

Toad Patrols Across the United Kingdom

Seeing many of toad carcasses on nearby streets "resonates deeply with people," and has led to the formation of rescue teams throughout the UK – hundreds of organizations are currently registered with a national initiative. These teams collect toads and transport them over streets in buckets, as well as counting the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and amphibian passages.

Volunteers tend to operate during the breeding period, when toad crossings are frequent. However, this means they can miss groups of toadlets, which, having been eggs and then juveniles, exit their water habitats over an unpredictable schedule in the end of summer. Because of their size – just one or two centimetres wide – "they can get obliterated by vehicles." And as being run over "essentially crushes them," it's harder to get data on them. At least when mature amphibians are lost, their carcasses can be tallied.

Annual Work

Unlike many groups, one local team, who are in their eighth year of operating, go out throughout the year – not every night, but whenever conditions are damp, or if someone has posted about a toad sighting in their messaging app. When I request to accompany them on duty, they admit it is "not a toady night" – winter dormancy has begun and it's been a arid period – but a few of the helpers gamely agree to patrol their area with me and see what we can find. "Should anyone can locate any toads tonight, that pair will find one," says the patrol manager, pointing to her 14-year-old son and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some logs.

Family Involvement

The mother and son joined the patrol a year and a half ago. The teenager adores all things nature-related and has an ambition to become a environmentalist, so his parent started to look for activities they could do jointly to protect native animals. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the group was looking for a fresh coordinator lately, she decided to step up.

The youth, too, has played an important role in the group. A clip he created, imploring the municipal authority to block a road through a protected area during migration season, swung the decision the team's way. After a twelve months of campaigning, the council approved an "restricted access" restriction between 5pm and 5am from February through to April. Most drivers respected and avoided the route.

Other Wildlife and Challenges

Several vehicles go past when I'm out on patrol and we find some casualties as a consequence – no amphibians, but three squashed newts. We spot one living newt as well, and the teenager is especially excited to see a daddy longlegs, which dances in his hands. Yet despite the group'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 better success elsewhere in the country – all the rescue teams I contact clarify that it's very difficult at this time of year.

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

One email I receive from another volunteer, who has generously made the effort to check for toads in a famous site, thought to be the biggest tracked toad group in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he informs me, the group expects to help approximately ten thousand 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 late nights is quite extraordinary," notes an researcher. "That's something that very much deserves recognition." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because traffic is just one danger.

Other Dangers

The global warming has meant extended spells of drought, which cause the wrong conditions for some of the animals that toads eat, such as invertebrates, while warmer ponds have led to an rise of blue-green algae, which can be harmful to toads. Milder winters also lead toads to wake up from their dormancy more frequently, disrupting the resource preservation crucial to their existence. Habitat destruction – particularly the disappearance of big water bodies – is an additional threat.

Researchers are "often concerned about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just their presence." But toads do have an important role in the ecosystem, consuming pretty much any invertebrates or small animals they can fit in their mouths and in turn sustaining a variety of predators, such as wildlife. Enhancing conditions for toads – ie building water habitats, conserving woodland and installing amphibian passages – "benefits for a wide range of other species."

Cultural Significance

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