Will Britain's Toads Survive from Traffic and Population Collapse?

It's a Friday night at 7:30, but instead of going out or relaxing at home, I've caught a train to a market town in the countryside to join local helpers from a toad patrol. These committed people sacrifice their evenings to safeguard the native amphibian community.

An Alarming Decline in Population

The common toad is growing more uncommon. A recent study led by an amphibian and reptile charity revealed that the UK toad population have dropped by half since the mid-1980s. Observing a creature that has been a fixture of the British countryside in decrease is described as "concerning" by researchers. Toads "don't need very particular environments" and "ought to live quite well in the majority of habitats in the UK," meaning if even they are not managing to survive, "it kind of suggests that things are not as they should be."

The Danger from Roads

Though the study didn't examine the reasons for the decline, cars is a major factor. Calculations indicate that 20 tons of toads are crushed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which might be happy to mate "with just a bucket of water," toads prefer big bodies of water. Their ability to remain away from water for more time than frogs allows they can journey farther to find them – sometimes long distances. They tend to stick to their ancestral migration routes – it's common for mature amphibians to return to their natal pond to mate.

Breeding Patterns

Appropriately enough, the first toads start their journey for a mate around Valentine's day, but others travel as late as April, waiting until it gets night and travelling after sunset. During that period, toads begin migrating from where they have been hibernating "almost simultaneously."

A local helper, who was raised in the region and has been trying to protect its amphibians since he was a boy, explains that "Their sole purpose: to go and mate." If their path happens to a road, they could all get run over, and that breeding season would be lost – preventing a next generation of toads from being produced.

Toad Patrols Throughout the United Kingdom

Seeing hundreds of toad carcasses on local roads "resonates deeply with people," and has led to the creation of rescue teams throughout the UK – 274 groups are officially listed with a countrywide program. These teams collect toads and transport them over streets in containers, as well as counting the quantity of toads they find and advocating for other protection measures, such as blocked roads and amphibian passages.

Patrols usually work during the migration season, when amphibian movements are more regular. However, this implies they can miss numbers of toadlets, which, having existed as spawn and then juveniles, leave their ponds over an irregular timetable in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "essentially crushes them," it's more difficult to get data on them. At least when mature amphibians are lost, their carcasses can be tallied.

Annual Efforts

Unlike most patrols, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not nightly, but when weather are warm and wet, or if someone has reported about a toad sighting in their messaging app. When I ask to join them on patrol, they concede it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but several of the volunteers willingly accept to patrol their area with me and search for any toads. "Should anyone can find any toads tonight, that pair will find one," says the group coordinator, indicating her teenage child and the longtime volunteer. We've been out for two hours without a single toad sighting, and now they have scaled a barbed wire fence to inspect beneath some logs.

Community Participation

The mother and son became part of the patrol a while back. The youngster loves all things wildlife and has an goal to become a environmentalist, so his mother started to look for activities they could do together to protect native animals. Now she loves it as much as he does, the middle-aged entrepreneur explains – so when the group was seeking a fresh coordinator lately, she decided to step up.

The teenager, too, has played an important role in the organization. A video 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 lobbying, the authority approved an "restricted access" restriction between evening and morning from late winter through to April. The majority of motorists respected and avoided the route.

Other Wildlife and Difficulties

A few cars go by when I'm out on patrol and we discover some casualties as a result – no toads, but three squashed newts. We see one live amphibian as well, and the teenager is especially excited to see a harvestman, which moves in his palms. Yet despite the team's hardest attempts to let me see a toad, the native community has clearly gone dormant for the winter. It appears that I wouldn't have had any better success anywhere else in the country – all the rescue teams I reach out to explain that it's very difficult at this season.

A message I receive from a different helper, who has kindly made the effort to check for toads in a noted location, considered the biggest tracked toad population in the UK, arrives in my inbox with the subject line: "No toads." However, in February and March, he informs me, the team expects to help around ten thousand adult toads over the street.

Impact and Challenges

How much of a difference can these organizations truly achieve? "The fact that volunteers are performing this regularly on cold, damp and unpleasant late nights is remarkable," says an expert. "That's something that very much should be celebrated." However, while toad patrols are able to slow the decline, they can't stop it completely – not least because traffic is not the only threat.

Other Dangers

The global warming has resulted in extended spells of drought, which create the poor environment for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have caused an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their dormancy more frequently, disrupting the resource preservation vital to their life cycle. Habitat destruction – particularly the loss of big water bodies – is another menace.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," however "It's important in just having these animals around." But toads play an important role in the ecosystem, consuming pretty much any invertebrates or tiny organisms they can fit in their mouths and in turn sustaining a number of predators, such as wildlife. Enhancing situations for toads – ie creating more ponds, conserving woodland and installing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Cultural Importance

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