Can the UK's Toads Survive from Roads and Population Collapse?

It's a Friday evening at half past seven, but instead of going out or relaxing at home, I've caught a train to a town in the countryside to join volunteers from a amphibian rescue group. These committed people sacrifice their evenings to protect the local toad population.

An Alarming Drop in Population

The common toad is becoming increasingly uncommon. A recent study conducted by an wildlife conservation group revealed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decrease is described as "worrying" by experts. Toads "don't require very specific conditions" and "should be able to live quite well in the majority of areas in Britain," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."

Toad populations across the UK have declined by almost 50% since the 1980s

The Danger from Roads

Though the study didn't examine the reasons for the decline, cars is a major factor. Estimates indicate that 20 tons of toads are killed on British roads annually – in other words, hundreds of thousands. In contrast to frogs, which might be content to mate "with just a bucket of water," toads favor big bodies of water. Their ability to remain away from water for more time than frogs allows they can travel further to find them – often long distances. They usually stick to their ancestral migration routes – it's common for adult toads to go back to their birth pond to mate.

Migration Habits

Fittingly, the initial amphibians begin their quest for a mate around February 14th, but some move as late as April, waiting until it gets night and travelling through the night. During that time, toads start moving from where they have been overwintering "all pretty much at the same time."

One volunteer, who grew up in the area and has been trying to protect its toad population since he was a boy, notes that "They've got just one focus: to go and mate." If their path happens to a road, they could be killed by traffic, and that breeding season would be lost – preventing a new generation of toads from being produced.

Rescue Groups Across the United Kingdom

Finding many of toad carcasses on nearby streets "resonates deeply with people," and has led to the formation of rescue teams throughout the UK – hundreds of organizations are officially listed with a countrywide program. These teams pick up toads and carry them over streets in containers, as well as counting the number of toads they find and advocating for other protection measures, such as road closures and amphibian passages.

Volunteers tend to operate during the breeding period, when amphibian movements are more regular. However, this implies they can miss groups of toadlets, which, having been eggs and then juveniles, exit their water habitats over an unpredictable schedule in late summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "essentially crushes them," it's more difficult to get data on them. At least when mature amphibians are killed, their carcasses can be tallied.

Year-Round Work

Unlike many groups, one local team, who are in their eighth season of functioning, go out year-round – not every night, but when weather are warm and wet, or if someone has posted about a amphibian spotting in their group chat. When I request to accompany them on patrol, they admit it is "not ideal conditions" – toad hibernation season has begun and it's been a arid period – but a few of the volunteers gamely agree 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 find one," says the group coordinator, indicating 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 logs.

Community Involvement

The mother and son became part of the patrol a year and a half ago. The teenager adores all things nature-related and has an ambition to become a environmentalist, so his mother started to look for activities they could do jointly to help native animals. Now she loves it as much as he does, the middle-aged entrepreneur tells me – so when the team was seeking a new manager lately, she volunteered for the role.

The teenager, too, has played an important role in the group. A video he created, imploring the municipal authority to close a road through a protected area during breeding time, influenced the outcome the group's way. After a twelve months of lobbying, the council approved an "access-only" rule between evening and morning from February through to spring. Most drivers respected and avoided the route.

Other Wildlife and Challenges

Several cars go past when I'm out on duty and we discover some victims as a result – no toads, but several crushed salamanders. We see one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which dances in his hands. Yet in spite of the team's best efforts to show me a toad, the local population has obviously gone dormant for the colder months. It seems that I couldn't have found any more luck elsewhere in the country – all the patrol groups I reach out to clarify that it's near-impossible 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 taken the trouble to check for toads in a noted location, considered the biggest tracked toad group in the UK, reaches me with the title: "None found." However, in February and March, he tells me, the group plans to assist approximately 10,000 mature amphibians across the road.

Effectiveness and Challenges

What level of impact can these organizations truly achieve? "The fact that volunteers are performing this consistently on cold, damp and unpleasant late nights is remarkable," says an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – not least because vehicles is not the only threat.

Other Dangers

The climate crisis has resulted in longer periods of dry weather, which cause the poor environment for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have led to an rise of blue-green algae, which can be harmful to toads. Milder winters also lead toads to wake up from their hibernation more frequently, interfering with the energy conservation vital to their life cycle. Habitat destruction – particularly the loss of big water bodies – is an additional threat.

Experts are "often concerned about putting too much of a utilitarian spin on biodiversity," however "It's important in just their presence." But toads play an significant part in the food chain, eating almost any invertebrates or tiny organisms they can fit in their mouths and in turn sustaining a variety of predators, such as hedgehogs and otters. Improving situations for toads – such as building water habitats, conserving woodland and installing amphibian passages – "we'll improve them for a whole bunch of other species."

Historical Importance

An additional motive to try to keep toads present is their "historical significance," adds an specialist. Legends and tales around toads date back {centuries|hundred
