Can Britain's Toads Be Saved from Roads and Terrible Decline?
It is a Friday night at 7:30, but rather than going out or relaxing at home, I've caught a train to a market town in the countryside 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 led by an amphibian and reptile charity revealed that the UK toad population have almost halved since the mid-1980s. Seeing a creature that has been a fixture of the British countryside in decline is described as "worrying" by experts. Toads "don't need very particular environments" and "ought to live quite well in the majority 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 Roads
Though the research didn't cover the causes for the decline, traffic certainly plays a part. Calculations indicate that 20 tons of toads are killed on British roads annually – that is, several hundred thousand. Unlike frogs, which might be happy to mate "with just a small container," toads prefer large ponds. Their capacity to stay out of water for longer than frogs means they can travel further to reach them – sometimes hundreds of metres. They tend to stick to their ancestral migration routes – it's common for adult toads to return to their birth pond to mate.
Migration Habits
Fittingly, the first toads start their journey for a mate around Valentine's day, but some move as late as spring, until it gets dark and travelling through the night. During that time, toads begin migrating from where they have been hibernating "all pretty much at the same time."
A local helper, who was raised in the region and has been trying to protect its toad population since he was a boy, notes that "Their sole purpose: to go and have an orgy." If their path crosses a road, they could be killed by traffic, and that mating period would be lost – preventing a next generation of toads from being produced.
Toad Patrols 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 – 274 groups are officially listed with a national initiative. These teams pick up toads and transport them over streets in containers, as well as counting the quantity of toads they find and lobbying for other protection measures, such as road closures and amphibian passages.
Patrols usually work during the breeding period, when amphibian movements are frequent. However, this implies they can miss groups of toadlets, which, having existed as spawn and then juveniles, leave their water habitats over an irregular timetable 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 harder to collect information on them. At least when adult toads are killed, their remains can be tallied.
Annual Efforts
In contrast to many groups, one local team, who are in their eighth season of operating, go out throughout the year – not every night, but when conditions are warm and wet, or if a member has posted about a amphibian spotting in their group chat. When I request to accompany them on patrol, they admit it is "not a toady night" – toad hibernation season has started and it's been a dry day – but several of the helpers gamely agree to patrol their area with me and search for any toads. "If anyone can locate any toads tonight, that pair will spot one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. After for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to inspect beneath some logs.
Community Participation
The mother and son joined the patrol a year and a half ago. The youngster loves all things wildlife and has an ambition to become a conservationist, so his parent started to look for things they could do together to help local wildlife. Now she enjoys it as much as he does, the 41-year-old entrepreneur explains – so when the team was looking for a new manager lately, she decided to step up.
The teenager, too, has been instrumental in the organization. A clip 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 twelve months of campaigning, the authority agreed to an "access-only" restriction between evening and morning from late winter through to spring. Most drivers duly avoided the route.
Additional Species and Difficulties
Several cars go by when I'm out on duty and we discover some victims as a consequence – no toads, but several crushed salamanders. We spot one live amphibian as well, and the youngster is especially excited to see a harvestman, which dances in his palms. Yet in spite of the team's best efforts to let me see a toad, the local population has obviously gone dormant for the winter. It seems that I couldn't have found any more luck anywhere else in the country – all the rescue teams I contact explain that it's near-impossible at this season.

One email I receive from another volunteer, who has generously taken the trouble to check for toads in a noted location, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he informs me, the team expects to help around 10,000 adult toads over the street.
Impact and Limitations
How much of a difference can these organizations actually make? "The reality that volunteers are doing this consistently on cold, damp and unpleasant late nights is remarkable," notes an researcher. "That's something that very much should be celebrated." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because traffic is just one danger.
Other Dangers
The climate crisis has meant longer periods of drought, which cause the wrong conditions for some of the creatures that toads eat, such as invertebrates, while higher water temperatures have led to an rise of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to emerge from their hibernation more often, disrupting the energy conservation crucial to their existence. Loss of environment – particularly the loss of large ponds – is an additional threat.
Researchers are "often concerned about putting too much of a utilitarian spin on biodiversity," but "There is a big value in just having these animals around." But toads play an significant part in the food chain, consuming almost any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a number of predators, such as wildlife. Enhancing conditions for toads – such as creating more ponds, protecting forests and constructing amphibian passages – "benefits for a wide range of other species."
Cultural Significance
Another reason to try to keep toads present is their "historical significance," adds an specialist. Legends and tales around toads go back {centuries|hundred
