Will the UK's Toads Survive from Traffic and Terrible Decline?

It is Friday night at half past seven, but rather than going out or watching a film, I've taken a train to a town in the countryside to join local helpers from a amphibian rescue group. These committed people give up their nights to protect the local toad population.

An Alarming Drop in Population

The Bufo bufo is growing more rare. A latest research conducted by an amphibian and reptile charity revealed that the UK toad population have almost halved since 1985. Observing a creature that has been a stalwart of the UK landscape in decline is described as "concerning" by researchers. Toads "don't need very particular environments" and "ought to live quite well in most of areas in Britain," 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 reasons for the decline, cars certainly plays a part. Estimates suggest that 20 tons of toads are crushed on British roads annually – that is, hundreds of thousands. Unlike frogs, which might be content to mate "with just a small container," toads favor big bodies of water. Their ability to remain away from water for longer than frogs means they can travel further to find them – sometimes hundreds of metres. They tend to follow their traditional paths – it's common for mature amphibians to return to their birth pond to mate.

Breeding Habits

Appropriately enough, the first toads start their journey for a mate around Valentine's day, but some move as far as April, until it gets night and travelling after sunset. During that time, toads start moving from where they have been hibernating "all pretty much at the same time."

A local helper, who grew up in the region and has been trying to protect its toad population since he was a child, notes that "They've got just one focus: to go and have an orgy." If their path happens to a road, they could be killed by traffic, and that breeding season would never happen – preventing a new generation of toads from being born.

Rescue Groups Throughout the UK

Seeing hundreds of dead toads on nearby streets "resonates deeply with people," and has resulted in the creation of toad patrols across the UK – hundreds of organizations are officially listed with a countrywide program. These groups collect toads and carry them over streets in containers, as well as recording the number of toads they encounter and advocating for other safety solutions, such as road closures and amphibian passages.

Volunteers usually work during the migration season, when toad crossings are frequent. However, this means they can miss groups of young toads, which, having been eggs and then tadpoles, exit their ponds over an unpredictable schedule in the end of summer. Because of their size – just one or two centimetres wide – "they are destroyed by car traffic." And as being run over "basically turns them into mush," it's more difficult to collect information on them. At least when mature amphibians are lost, their remains can be counted.

Year-Round Efforts

In contrast to most patrols, one local team, 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 amphibian spotting in their group chat. When I ask to join them on patrol, they admit it is "not a toady night" – winter dormancy has started and it's been a dry day – but several of the helpers willingly accept to walk up and down their route with me and see what we can find. "Should anyone can locate any toads tonight, those two will spot one," says the patrol manager, pointing to her teenage child and the longtime volunteer. After for 120 minutes without a single toad sighting, and now they have scaled a barbed wire fence to check under some wood.

Community Involvement

The mother and son joined the patrol 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 jointly to help native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur explains – so when the team was looking for a new manager recently, she decided to step up.

The teenager, too, has been instrumental in the group. A clip he made, urging the municipal authority to block a road through a protected area during migration season, swung the decision the group's way. After a year of lobbying, the council agreed to an "restricted access" restriction between 5pm and 5am from February through to April. The majority of motorists respected and avoided the road.

Other Wildlife and Difficulties

A few cars go past when I'm out on patrol and we discover some casualties as a consequence – no amphibians, but three squashed newts. We see one live amphibian as well, and the youngster is particularly pleased to see a harvestman, which moves in his hands. Yet despite the group's hardest attempts to show me a toad, the native community has clearly gone dormant for the winter. It appears that I couldn't have found any better success anywhere else in the country – all the patrol groups I reach out to clarify that it's very difficult at this season.

The group expects to help approximately 10,000 adult toads across the road

A message I receive from a different helper, who has generously made the effort to check for toads in a famous site, considered the biggest tracked toad group in the UK, reaches me with the title: "No toads." However, in late winter, he tells me, the group expects to help around 10,000 mature amphibians across the road.

Effectiveness and Limitations

How much of a difference can these organizations actually make? "The reality that people are performing this regularly on chilly, wet and miserable late nights is remarkable," notes an researcher. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – not least because traffic is just one danger.

Other Dangers

The climate crisis has resulted in extended spells of dry weather, which cause the wrong conditions for some of the creatures that toads eat, such as invertebrates, while higher water temperatures have caused an increase of blue-green algae, which can be harmful to toads. Milder winters also cause toads to wake up from their hibernation more often, interfering with the resource preservation crucial to their life cycle. Habitat destruction – especially the loss of large ponds – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," but "It's important in just having these animals around." But toads play an significant part in the food chain, eating pretty much any invertebrates or small animals they can swallow and in turn feeding a variety of birds and mammals, such as wildlife. Enhancing situations for toads – such as building water habitats, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Historical Significance

Another reason to work to preserve toads present is their "important cultural value," adds an expert. Legends and tales around toads go back {centuries|hundred
