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

It is a Friday night at half past seven, but rather than going out or relaxing at home, I've taken a train to a market town in Wiltshire to join volunteers from a toad patrol. These committed people sacrifice their nights to safeguard the native amphibian community.

A Worrying Decline in Population

The common toad is becoming increasingly rare. A recent research conducted by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since 1985. Observing a creature that has been a fixture of the UK landscape in decline is described as "concerning" by researchers. Toads "don't need very specific conditions" and "should be able to live successfully in most of areas 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 Traffic

Though the study didn't examine the reasons for the drop, cars certainly plays a part. Calculations indicate that 20 tonnes of toads are killed on UK roads annually – that is, several hundred thousand. In contrast to frogs, which would probably be happy to mate "with just a small container," toads favor large ponds. Their ability to stay out of water for more time than frogs means they can travel further to reach them – sometimes long distances. They tend to stick to their traditional paths – it's typical for adult toads to go back to their birth pond to mate.

Breeding Habits

Fittingly, the first toads start their journey for a partner around Valentine's day, but some move as far as spring, until it gets dark and travelling after sunset. During that time, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."

A local helper, who grew up in the area and has been working to save its amphibians since he was a boy, explains that "They've got just one focus: to go and have an orgy." If their route happens to a street, they could be killed by traffic, and that mating period would never happen – stopping a next generation of toads from being born.

Rescue Groups Across the UK

Seeing many of toad carcasses on nearby streets "inherently strikes a chord with people," and has resulted in the formation of rescue teams throughout 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 counting the quantity of toads they encounter and advocating for other safety solutions, such as blocked roads and amphibian passages.

Patrols usually work during the breeding period, when toad crossings are more regular. However, this means they can overlook numbers of young toads, which, having existed as spawn and then juveniles, exit their ponds over an unpredictable schedule in late summer. Because of their small stature – just a couple of cm wide – "they can get obliterated by car traffic." And as being hit "basically turns them into mush," it's more difficult to get data on them. At least when mature amphibians are lost, their carcasses can be counted.

Year-Round Work

Unlike many groups, a specific volunteer group, who are in their eighth year of operating, go out throughout the year – not nightly, but whenever conditions are damp, or if a member has posted about a toad sighting in their group chat. When I ask to join them on duty, they concede it is "not a toady night" – winter dormancy has begun and it's been a arid period – but several of the volunteers willingly accept to patrol their route with me and see what we can find. "Should anyone can find any toads tonight, that pair will find one," says the patrol manager, pointing to her teenage child and the experienced member. After for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to inspect beneath some logs.

Family Involvement

The mother and son joined the group a while back. The teenager loves all things nature-related and has an ambition to become a conservationist, so his parent started to look for things they could do jointly to help local wildlife. Now she loves it as much as he does, the middle-aged entrepreneur tells me – so when the team was seeking a fresh coordinator lately, she volunteered for the role.

The youth, too, has been instrumental in the organization. A video he created, imploring the municipal authority to block a street through a protected area during migration season, influenced the outcome the group's way. After a year of campaigning, the council approved an "restricted access" rule between evening and morning from February through to April. The majority of motorists respected and avoided the route.

Other Wildlife and Challenges

Several vehicles go by when I'm out on patrol and we discover some victims as a result – no toads, but several crushed salamanders. We spot one live amphibian as well, and the youngster is particularly pleased to see a harvestman, which moves in his palms. Yet despite the team's best efforts to show me a toad, the local population has obviously settled down for the winter. It appears that I wouldn't have had any better success elsewhere in the country – all the rescue teams I contact clarify that it's near-impossible at this time of year.

A message I receive from another volunteer, who has generously made the effort to check for toads in a famous site, thought to be the biggest tracked toad population in the UK, reaches me with the title: "None found." However, in February and March, he informs me, the team plans to assist around 10,000 adult toads over the street.

Effectiveness and Limitations

What level of impact can these groups truly achieve? "The reality that volunteers are doing this consistently on cold, damp and unpleasant late nights is remarkable," notes an researcher. "This effort that very much should be celebrated." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – not least because traffic is not the only threat.

Other Dangers

The global warming has resulted in extended spells of dry weather, which create the poor environment for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have caused 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 resource preservation vital to their existence. Habitat destruction – particularly the disappearance of big water bodies – is an additional threat.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," but "There is a big value in just having these animals around." But toads play an significant part in the ecosystem, consuming almost any invertebrates or small animals they can fit in their mouths and in turn sustaining a number of predators, such as wildlife. Improving situations for toads – ie building water habitats, protecting forests and installing toad tunnels – "benefits for a whole bunch of additional wildlife."

Cultural Significance

Another reason to try to keep toads around is their "important cultural value," notes an specialist. Myths and folklore around toads go back {centuries|hundred
