Can Britain's Toads Be Saved from Traffic and Terrible Decline?

It's a Friday evening at 7:30, but rather than heading to the pub or watching a film, I've caught a train to a market town in the countryside to meet up with local helpers from a toad patrol. These dedicated individuals give up their nights to safeguard the native amphibian community.

A Worrying Decline in Population

The common toad is growing more rare. A recent study led by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since the mid-1980s. Observing a species that has been a stalwart of the UK landscape in decline is labeled "concerning" by researchers. Toads "don't require very particular environments" and "should be able to live quite well in most of areas in Britain," so if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

The Threat from Roads

Though the research didn't cover the reasons for the drop, traffic certainly plays a part. Estimates indicate that 20 tonnes of toads are crushed on UK roads annually – that is, hundreds of thousands. Unlike frogs, which might be happy to mate "with just a bucket of water," toads prefer big bodies of water. Their capacity to stay out of water for longer than frogs allows they can travel further to reach them – often hundreds of metres. They tend to follow their ancestral migration routes – it's common for mature amphibians to go back to their natal pond to mate.

Breeding Habits

Fittingly, the initial amphibians start their journey for a mate around Valentine's day, but others travel as late as spring, until it gets night and moving through the night. During that period, toads start moving from wherever they have been overwintering "almost simultaneously."

One volunteer, who grew up in the area and has been trying to protect its toad population since he was a child, notes that "Their sole purpose: to go and have an orgy." If their route happens to a road, they could be killed by traffic, and that breeding season would be lost – preventing a next generation of toads from being produced.

Toad Patrols Throughout the United Kingdom

Finding hundreds of toad carcasses on local roads "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 containers, as well as recording the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and amphibian passages.

Patrols tend to operate during the migration season, when amphibian movements are more regular. However, this implies they can miss numbers of toadlets, which, having been spawn and then tadpoles, leave their ponds over an irregular timetable in the end of summer. Because of their small stature – just a couple of cm wide – "they are destroyed by vehicles." And as being hit "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.

Annual Efforts

In contrast to many groups, one local team, who are in their eighth year of functioning, go out year-round – not every night, but when conditions are damp, or if a member has reported about a amphibian spotting in their group chat. When I ask to join them on duty, they admit it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but a few of the volunteers gamely agree to walk up and down their route with me and search for any toads. "Should anyone can locate any toads tonight, that pair will find one," says the group coordinator, pointing to her 14-year-old son and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to inspect beneath some wood.

Community Participation

The family duo joined the patrol a while back. The youngster loves all things wildlife and has an ambition to become a environmentalist, so his parent started to search for things they could do jointly to protect native animals. Now she loves it as much as he does, the 41-year-old entrepreneur tells me – so when the group was seeking a new manager recently, she decided to step up.

The teenager, too, has been instrumental in the organization. A video he created, urging the local council to close a street through a protected area during migration season, influenced the outcome the group's way. After a twelve months of lobbying, the authority agreed to an "restricted access" restriction between 5pm and 5am from late winter through to spring. Most drivers duly avoided the road.

Other Wildlife and Difficulties

Several vehicles go by when I'm out on duty and we find some victims as a result – no amphibians, but several crushed salamanders. We spot one living newt as well, and the youngster is especially excited to see a daddy longlegs, which moves in his palms. Yet despite the team's hardest attempts to let me see a toad, the native community has clearly settled down for the winter. It appears that I wouldn't have had any better success anywhere else in the nation – all the rescue teams I reach out to explain that it's very difficult at this time of year.

This team anticipates assisting around ten thousand mature toads over the street

One email I receive from another volunteer, who has kindly taken the trouble to check for toads in a noted location, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the title: "No toads." However, in late winter, he tells me, the team expects to help approximately ten thousand mature amphibians over the street.

Effectiveness and Limitations

What level of impact can these groups actually make? "The fact that volunteers are doing this regularly on cold, damp and unpleasant 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 – partly since vehicles is just one danger.

Additional Threats

The climate crisis has resulted in extended spells of dry weather, which create the wrong conditions for some of the animals that toads eat, such as invertebrates, while warmer ponds have caused an rise of toxic plants, which can be toxic to toads. Warmer cold seasons 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 another menace.

Experts are "always a bit worried about overemphasizing practical benefits on wildlife," but "There is a big value in just their presence." But toads do have an important role in the food chain, consuming almost any invertebrates or small animals they can swallow and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Improving situations for toads – such as building water habitats, protecting forests and constructing amphibian passages – "we'll improve them for a wide range of other species."

Cultural Significance

Another reason to try to keep toads around is their "historical significance," notes an expert. Myths and folklore around toads go back {centuries|hundred
