It is Friday evening at 7:30, but instead of heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to join volunteers from a toad patrol. These committed people give up their nights to protect the native amphibian community.

An Alarming Drop in Population

The common toad is growing more rare. A latest research led by an amphibian and reptile charity showed that the UK toad population have dropped by half since 1985. Observing a creature that has been a stalwart of the UK landscape in decline is described as "worrying" by researchers. Toads "don't need very specific conditions" and "should be able to live successfully in the majority of habitats in the UK," so 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 Threat from Roads

Though the study didn't cover the causes for the decline, traffic is a major factor. Estimates suggest that 20 tons of toads are killed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which might be content to mate "with just a small container," toads prefer large ponds. Their ability to stay out of 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 adult toads to go back to their birth pond to mate.

Breeding Patterns

Fittingly, the first toads begin their quest for a partner around February 14th, but some move as far as April, waiting until it gets dark and travelling through the night. During that period, toads start moving from wherever they have been overwintering "almost simultaneously."

One volunteer, who grew up in the region and has been working to save its toad population since he was a boy, explains that "Their sole purpose: to go and mate." If their route crosses a road, they could be killed by traffic, and that mating period would never happen – preventing a next generation of toads from being produced.

Rescue Groups Throughout the United Kingdom

Seeing many of toad carcasses on nearby streets "resonates deeply with people," and has led to the creation of rescue teams across the UK – 274 groups are officially listed with a countrywide program. These groups collect toads and transport them across roads in buckets, as well as recording the number of toads they find and lobbying for other safety solutions, such as road closures and amphibian passages.

Patrols tend to operate during the migration season, when amphibian movements are frequent. However, this implies they can miss numbers of young toads, which, having been spawn and then tadpoles, exit their water habitats over an irregular timetable in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by vehicles." And as being run over "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 tallied.

Year-Round Work

In contrast to most patrols, a specific volunteer group, who are in their eighth season of functioning, go out throughout the year – not nightly, but whenever weather are warm and wet, or if a member has posted about a amphibian spotting in their group chat. When I ask to join them on patrol, they concede it is "not ideal conditions" – toad hibernation season has begun and it's been a dry day – but a few of the helpers gamely agree to walk up and down their route with me and search for any toads. "If anyone can locate any toads tonight, that pair will spot one," says the group coordinator, pointing to her teenage child and the experienced member. We've been out for two hours without a single toad sighting, and now they have scaled a barbed wire fence to check under some wood.

Community Participation

The family duo joined the group a while back. The youngster adores all things nature-related and has an goal to become a environmentalist, so his parent started to look for things they could do together to protect native animals. Now she loves it as much as he does, the 41-year-old small business owner explains – so when the team was looking for a fresh coordinator recently, she volunteered for the role.

The teenager, too, has played an important role in the group. A clip he created, urging the municipal authority to block a street through a nature reserve during migration season, influenced the outcome the group's way. After a twelve months of lobbying, the authority agreed to an "access-only" rule between evening and morning from late winter through to spring. Most drivers respected and avoided the route.

Additional Species and Difficulties

Several vehicles go by when I'm out on patrol 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 clearly gone dormant for the colder months. It seems that I wouldn't have had any more luck anywhere else in the nation – all the rescue teams I reach out to explain that it's near-impossible at this season.

They project rescuing nearly 10,000 grown amphibians during migration

A message I get from another volunteer, who has kindly taken the trouble to check for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, reaches me with the subject line: "No toads." However, in late winter, he informs me, the team expects to help around 10,000 mature amphibians over the street.

Impact and Challenges

How much of a difference can these groups truly achieve? "The fact that volunteers are performing this regularly on chilly, wet and miserable evenings is remarkable," says an expert. "This effort that very much should be celebrated." However, while toad patrols are able to slow the decline, they can't stop it completely – partly since vehicles is not the only threat.

Other Dangers

The global warming has meant longer periods of dry weather, which create the wrong conditions for some of the creatures that toads consume, 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 emerge from their dormancy more frequently, disrupting the energy conservation crucial to their life cycle. Habitat destruction – particularly the loss of large ponds – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," but "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 sustaining a number of predators, such as wildlife. Enhancing situations for toads – ie building water habitats, conserving woodland and installing amphibian passages – "benefits for a whole bunch of additional wildlife."

Historical Importance

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