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

An Alarming Drop in Population

The common toad is growing more uncommon. A latest research led by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since 1985. Observing a species that has been a fixture of the UK landscape in decrease is labeled "concerning" by experts. Toads "don't require very particular environments" and "should be able to live quite well in most of habitats in Britain," meaning if even they are struggling to persist, "it indicates 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 causes for the decline, traffic is a major factor. Estimates suggest that 20 tons of toads are crushed on British roads every year – in other words, hundreds of thousands. Unlike frogs, which would probably be content to mate "if you left out 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 – often long distances. They tend to follow their traditional paths – it's typical for mature amphibians to return to their natal pond to mate.

Breeding Habits

Fittingly, the first toads begin their quest for a mate around Valentine's day, but others travel as late as April, waiting until it gets night and travelling through the night. During that period, toads start moving from wherever they have been hibernating "all pretty much at the same time."

A local helper, who was raised in the region and has been working to save its amphibians since he was a boy, explains that "Their sole purpose: to go and have an orgy." If their route crosses a street, they could all get run over, and that breeding season would never happen – preventing a new generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Seeing many of toad carcasses on nearby streets "resonates deeply with people," and has led to the formation of toad patrols across the UK – hundreds of organizations are officially listed with a countrywide program. These teams collect toads and transport them over streets in containers, as well as counting the number of toads they find and lobbying for other safety solutions, such as blocked roads and amphibian passages.

Volunteers usually work during the migration season, when amphibian movements are more regular. However, this means they can miss numbers of toadlets, which, having been spawn and then juveniles, leave their water habitats over an unpredictable schedule in the end of summer. Because of their small stature – just a couple of cm wide – "they are destroyed by car traffic." And as being hit "basically turns them into mush," it's more difficult to get data on them. At least when adult toads are killed, their remains can be tallied.

Year-Round Efforts

Unlike most patrols, a specific volunteer group, who are in their eighth season of operating, go out year-round – not nightly, but whenever weather are damp, or if someone has posted about a toad sighting in their group chat. When I request to accompany them on patrol, they concede it is "not a toady night" – winter dormancy has started and it's been a arid period – but several of the volunteers gamely agree to patrol their area with me and see what we can find. "If anyone can locate any toads tonight, that pair will spot one," says the group coordinator, pointing to her 14-year-old son and the experienced member. After for 120 minutes without a single toad sighting, and now they have climbed over a wire barrier to check under some wood.

Community Participation

The mother and son became part of the patrol a year and a half ago. The youngster loves all things wildlife and has an ambition to become a conservationist, so his mother started to look for things they could do jointly to protect native animals. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the team was seeking a new manager recently, she volunteered for the role.

The teenager, too, has played an important role in the group. A video he made, urging the local council to block a road through a nature reserve during migration season, swung the decision the team's way. After a twelve months of lobbying, the council approved an "restricted access" restriction between 5pm and 5am from February through to April. The majority of motorists duly avoided the road.

Additional Species and Challenges

A few cars go by when I'm out on duty and we discover some victims as a consequence – no amphibians, but several crushed salamanders. We spot one living newt as well, and the youngster is especially excited to see a harvestman, which dances in his palms. Yet despite the team's hardest attempts to show me a toad, the local population has clearly gone dormant for the winter. It seems that I couldn't have found any more luck elsewhere in the country – all the rescue teams I contact clarify that it's near-impossible at this time of year.

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 largest accurately monitored toad group in the UK, reaches me with the title: "None found." However, in February and March, he tells me, the team plans to assist around ten thousand mature amphibians over the street.

Impact and Limitations

What level of impact can these groups truly achieve? "The reality that people are doing this regularly on cold, damp and unpleasant evenings is quite extraordinary," says an expert. "That's something that very much deserves recognition." However, while rescue teams are able to reduce the drop, they can't stop it completely – partly since vehicles is just one danger.

Additional Threats

The global warming has resulted in extended spells of drought, which create the poor environment for some of the animals that toads consume, such as invertebrates, while higher water temperatures have led to an rise of blue-green algae, which can be toxic to toads. Milder winters also cause toads to wake up from their dormancy more often, interfering with the resource preservation vital to their existence. Loss of environment – especially the disappearance of large ponds – is an additional threat.

Experts are "always a bit worried about overemphasizing practical benefits on wildlife," but "There is a big value in just their presence." But toads play an significant part in the food chain, consuming pretty much any invertebrates or tiny organisms they can swallow and in turn sustaining a variety of predators, such as wildlife. Improving conditions for toads – such as creating more ponds, conserving woodland and installing amphibian passages – "we'll improve them for a wide range of other species."

Cultural Significance

An additional motive to work to preserve toads around is their "historical significance," notes an expert. Legends and tales around toads date back {centuries|hundred
