Can Britain's Toads Be Saved from Traffic and Population Collapse?

It's Friday night at 7:30, but rather than going out or watching a film, I've taken a train to a town in Wiltshire to join volunteers from a amphibian rescue group. These committed people give up their evenings to safeguard the native amphibian community.

A Worrying Decline in Population

The common toad is growing more rare. A recent study conducted 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 stalwart of the British countryside in decline is labeled "concerning" by researchers. Toads "don't need very particular environments" and "should be able to live quite well in most of habitats in Britain," so if even they are struggling to persist, "it kind of suggests that things are not as they should be."

The Threat from Roads

Though the research didn't examine the causes for the decline, traffic certainly plays a part. Calculations indicate that 20 tons of toads are crushed on British roads every year – that is, several hundred thousand. In contrast to frogs, which might be content to mate "if you left out a bucket of water," toads prefer large ponds. Their capacity to stay out of water for longer than frogs means they can travel further to find them – sometimes hundreds of metres. They tend to 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 initial amphibians begin their quest for a partner around February 14th, but some move as far as spring, until it gets dark and moving through the night. During that time, toads start moving from where they have been overwintering "all pretty much at the same time."

A local helper, who was raised in the area and has been trying to protect its amphibians since he was a child, notes that "Their sole purpose: to go and mate." If their route crosses a road, they could be killed by traffic, and that breeding season would be lost – preventing a next generation of toads from being produced.

Rescue Groups Throughout the UK

Finding many of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the formation of rescue teams across the UK – hundreds of organizations are currently registered with a countrywide program. These groups collect toads and transport them over streets in buckets, as well as recording the quantity of toads they encounter and advocating for other protection measures, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the breeding period, when toad crossings are frequent. However, this implies they can overlook groups of young toads, which, having existed as eggs and then juveniles, leave their ponds over an unpredictable schedule in late summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "basically turns them into mush," it's harder to get data on them. At least when mature amphibians are killed, their remains can be tallied.

Year-Round Work

Unlike many groups, a specific volunteer group, who are in their eighth season of functioning, go out year-round – not nightly, but whenever conditions are warm and wet, or if a member has reported about a amphibian spotting in their messaging app. When I ask to join them on patrol, they admit it is "not ideal conditions" – 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 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 14-year-old son and the experienced member. After for two hours without a single toad sighting, and now they have climbed over a wire barrier to check under some logs.

Family Involvement

The family duo became part of the group a year and a half ago. The teenager loves all things wildlife and has an goal to become a environmentalist, so his parent started to search for things they could do jointly to protect local wildlife. 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 new manager lately, she volunteered for the role.

The teenager, too, has been instrumental in the group. A video he made, imploring the local council to close a street through a nature reserve during breeding time, swung the decision the team's way. After a twelve months of campaigning, the authority agreed to an "restricted access" restriction between evening and morning from late winter through to spring. The majority of motorists respected and avoided the route.

Other Wildlife and Difficulties

Several vehicles go by when I'm out on patrol and we find some casualties as a consequence – no toads, but three squashed newts. We see one living newt as well, and the youngster is especially excited to see a daddy longlegs, which moves in his hands. Yet despite the team's best efforts to show me a toad, the local population has obviously gone dormant for the winter. It seems that I wouldn't have had any better success elsewhere in the country – all the patrol groups I contact clarify that it's near-impossible at this time of year.

One email I get from a different helper, who has generously made the effort to check for toads in a noted location, considered the biggest tracked toad group in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he tells me, the team plans to assist around 10,000 adult toads across the road.

Effectiveness and Challenges

How much of a difference can these organizations actually make? "The fact that people are doing this consistently on chilly, wet and miserable late nights is remarkable," says an expert. "This effort that very much deserves recognition." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – partly since traffic is just one danger.

Other Dangers

The climate crisis has meant longer periods of drought, which create the poor environment for some of the creatures that toads consume, such as invertebrates, while higher water temperatures have led to an rise of blue-green algae, which can be harmful to toads. Warmer cold seasons also cause toads to emerge from their hibernation more often, interfering with the energy conservation crucial to their life cycle. Habitat destruction – particularly the disappearance of large ponds – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," however "It's important in just having these animals around." But toads play an significant part in the food chain, eating almost any invertebrates or small animals they can swallow and in turn sustaining a number of predators, such as hedgehogs and otters. Improving conditions for toads – such as creating more ponds, protecting forests and installing 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 "important cultural value," notes an specialist. Legends and tales around toads go back {centuries|hundred
