It is Friday night at half past seven, but instead of going out or relaxing at home, I've taken a train to a town in Wiltshire to join local helpers from a amphibian rescue group. These dedicated individuals give up their evenings to safeguard the local toad population.

An Alarming Drop in Population

The common toad is becoming increasingly rare. A latest research led by an amphibian and reptile charity showed that the British common toad numbers have dropped by half since 1985. Seeing a species that has been a stalwart of the British countryside in decline is labeled "worrying" by researchers. Toads "don't require very specific conditions" and "should be able to live quite well in the majority of areas in the UK," so if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

The Threat from Traffic

Though the study didn't cover the causes for the decline, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are crushed on UK roads annually – that is, hundreds of thousands. Unlike frogs, which would probably be happy to mate "if you left out a small container," toads favor large ponds. Their ability to stay out of water for longer than frogs allows they can travel further to find them – sometimes hundreds of metres. They tend to stick to their ancestral migration routes – it's typical for adult toads to go back to their birth pond to mate.

Migration Patterns

Fittingly, the initial amphibians begin their quest for a mate around February 14th, but others travel as late as spring, waiting until it gets night and moving through the night. During that time, toads begin migrating from where they have been overwintering "almost simultaneously."

One volunteer, who grew up in the area and has been working to save its toad population since he was a boy, explains that "They've got just one focus: to go and have an orgy." If their route crosses a street, they could all get run over, and that breeding season would be lost – preventing a next generation of toads from being produced.

Toad Patrols Across the United Kingdom

Finding hundreds of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the formation of toad patrols across the UK – 274 groups are currently registered with a national initiative. These groups collect toads and carry them over streets in containers, as well as recording the quantity of toads they encounter and lobbying for other protection measures, such as road closures and underground wildlife tunnels.

Volunteers usually work during the breeding period, when toad crossings are more regular. However, this means they can miss groups of toadlets, which, having existed as eggs and then tadpoles, exit their ponds over an unpredictable schedule in late summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are lost, their remains can be tallied.

Year-Round Work

Unlike many groups, a specific volunteer group, who are in their eighth year of functioning, go out throughout the year – not every night, but whenever conditions are damp, or if someone has posted about a toad sighting in their messaging app. When I ask to join them on patrol, they admit it is "not ideal conditions" – toad hibernation season has begun and it's been a dry day – but several of the helpers gamely agree to walk up and down their area with me and search for any toads. "If anyone can locate any toads tonight, those two will spot one," says the group coordinator, pointing to her teenage child and the longtime volunteer. After for two hours without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some wood.

Community Involvement

The mother and son became part of the patrol a while back. The youngster adores all things wildlife and has an ambition to become a conservationist, so his parent started to search for activities they could do jointly to protect local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur explains – so when the group was seeking a fresh coordinator recently, she volunteered for the role.

The youth, too, has played an important role in the group. A video he made, urging the local council to block a road through a protected area during breeding time, influenced the outcome the group's way. After a year of campaigning, the authority approved an "access-only" rule between 5pm and 5am from February through to spring. Most drivers respected and avoided the route.

Additional Species and Challenges

Several vehicles go by when I'm out on patrol and we find some victims as a result – no toads, but several crushed salamanders. We see one live amphibian as well, and the youngster is especially excited to see a harvestman, which dances in his palms. Yet despite the team'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 elsewhere in the country – all the rescue teams I contact 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 made the effort to look for toads in a noted location, thought to be the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "No toads." However, in February and March, he informs me, the group plans to assist approximately 10,000 adult toads over the street.

Impact and Limitations

What level of impact can these organizations truly achieve? "The reality that volunteers are doing this regularly on chilly, wet and miserable evenings is quite extraordinary," says an expert. "That's something that very much should be celebrated." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since traffic is not the only threat.

Other Dangers

The global warming has resulted in longer periods of drought, which create the poor environment for some of the animals that toads eat, such as invertebrates, while higher water temperatures have led to an increase of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to emerge from their dormancy more often, interfering with the resource preservation vital to their life cycle. Loss of environment – particularly the disappearance of large ponds – is another menace.

Researchers are "often concerned 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 small creatures or small animals they can fit in their mouths and in turn feeding a number of predators, such as hedgehogs and otters. Improving conditions for toads – ie creating more ponds, protecting forests and constructing toad tunnels – "benefits for a whole bunch of other species."

Historical Significance

An additional motive to try to keep toads around is their "important cultural value," notes an specialist. Legends and tales around toads date back {centuries|hundred
