Can Britain's Common Toads Survive from Traffic and Population Collapse?

It is a Friday evening at half past seven, but instead of heading to the pub or watching a film, I've caught a train to a market town in Wiltshire to meet up with local helpers from a amphibian rescue group. These committed people give up their nights to safeguard the local toad population.

An Alarming Decline in Population

The common toad is growing more rare. A latest research led by an wildlife conservation group revealed that the UK toad population have almost halved since the mid-1980s. Seeing a species that has been a fixture of the British countryside in decline is labeled "worrying" by experts. Toads "don't require very specific conditions" and "should be able to live successfully in the majority of habitats in Britain," so if even they are not managing to survive, "it kind of suggests that things are not as they should be."

Since 1985, Britain's toad numbers have nearly been cut in half

The Danger from Roads

Though the study didn't examine the causes for the decline, cars certainly plays a part. Calculations indicate that 20 tons of toads are crushed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be content to mate "if you left out a bucket of water," toads favor large ponds. Their ability to stay out of water for more time than frogs means they can travel further to reach them – often long distances. They tend to follow their ancestral migration routes – it's typical for adult toads to go back to their natal pond to mate.

Migration Habits

Appropriately enough, the initial amphibians start their journey for a partner around February 14th, but some move as late as April, waiting until it gets dark and moving through the night. During that time, toads start moving from wherever they have been overwintering "almost simultaneously."

One volunteer, who was raised in the area and has been working to save its amphibians since he was a child, notes that "They've got just one focus: to go and mate." If their route happens to a road, they could be killed by traffic, and that mating period would never happen – stopping a new generation of toads from being born.

Toad Patrols Across the United Kingdom

Seeing hundreds of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the formation of toad patrols across the UK – hundreds of organizations are officially listed with a countrywide program. These groups pick up toads and transport them over streets in buckets, as well as counting the number of toads they find and lobbying for other protection measures, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the migration season, when amphibian movements are more regular. However, this means they can overlook numbers of toadlets, which, having existed as eggs and then juveniles, leave their ponds over an unpredictable schedule in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." And as being hit "essentially crushes them," it's more difficult to collect information on them. At least when adult toads are killed, their carcasses can be tallied.

Annual Work

Unlike most patrols, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not nightly, but when weather are damp, or if a member has reported about a amphibian spotting in their messaging app. When I request to accompany them on duty, they admit it is "not a toady night" – winter dormancy has begun and it's been a arid period – but a few of the helpers willingly accept to patrol their route with me and search for any toads. "Should anyone can find any toads tonight, those two will find one," says the group coordinator, pointing to her teenage child and the longtime volunteer. After for two hours without a single toad sighting, and now they have climbed over a wire barrier to check under some wood.

Family Participation

The family duo became part of the patrol a while back. The youngster adores all things nature-related and has an ambition to become a conservationist, so his mother started to search for activities they could do jointly to help native animals. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the team was looking for a fresh coordinator recently, she volunteered for the role.

The youth, too, has been instrumental in the organization. A video he created, urging the local council to close a road through a protected area during breeding time, swung the decision the team's way. After a twelve months of campaigning, the council approved an "access-only" rule between 5pm and 5am from February through to spring. The majority of motorists duly avoided the route.

Other Wildlife and Difficulties

Several cars go past when I'm out on duty and we find some victims as a consequence – no amphibians, but several crushed salamanders. We spot one live amphibian as well, and the teenager is especially excited to see a harvestman, which moves in his hands. Yet in spite of the group's best efforts to let me see a toad, the native community has clearly settled down for the colder months. It appears that I wouldn't have had any better success anywhere else in the nation – all the patrol groups I contact explain that it's near-impossible at this season.

They project rescuing nearly 10,000 grown amphibians during migration

One email I receive from another volunteer, who has kindly made the effort to check for toads in a famous site, considered the biggest tracked toad group in the UK, reaches me with the subject line: "None found." However, in late winter, he tells me, the group plans to assist approximately 10,000 adult toads across the road.

Impact and Limitations

What level of impact can these organizations actually make? "The fact that people are performing this regularly on cold, damp and unpleasant evenings is quite extraordinary," notes an researcher. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – partly since traffic is just one danger.

Additional Threats

The climate crisis has meant extended spells of drought, which cause the wrong conditions for some of the creatures that toads consume, such as invertebrates, while higher water temperatures have caused an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to wake up from their hibernation more often, disrupting the energy conservation vital to their life cycle. Habitat destruction – particularly the disappearance of large ponds – is another menace.

Researchers are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just having these animals around." But toads play an important role in the ecosystem, consuming pretty much any small creatures or small animals they can swallow and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Enhancing conditions for toads – ie building water habitats, protecting forests and installing amphibian passages – "benefits for a whole bunch of additional wildlife."

Historical Importance

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