It's 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 the countryside to join volunteers from a toad patrol. These committed people sacrifice their evenings to protect the local toad population.

A Worrying Drop in Numbers

The Bufo bufo is growing more rare. A recent research conducted by an amphibian and reptile charity showed that the British common toad numbers have dropped by half since the mid-1980s. Observing a creature 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 successfully in the majority of areas in the UK," meaning if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

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

The Threat from Traffic

Though the research didn't examine the reasons for the drop, traffic certainly plays a part. Estimates suggest that 20 tons of toads are crushed on British roads every year – that is, several hundred thousand. In contrast to frogs, which might be happy to mate "with just a small container," toads prefer big bodies of water. Their ability to remain away from water for more time than frogs means they can journey farther to reach them – sometimes hundreds of metres. They tend to follow their ancestral migration routes – it's typical for mature amphibians to go back to their birth pond to mate.

Migration Patterns

Appropriately enough, the first toads start their journey for a mate around Valentine's day, but others travel as late as April, waiting until it gets night and travelling after sunset. During that period, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."

One volunteer, who was raised in the area and has been working to save its toad population since he was a boy, notes that "Their sole purpose: to go and mate." If their path crosses a street, they could be killed by traffic, and that breeding season would never happen – stopping a new generation of toads from being produced.

Rescue Groups Across the United Kingdom

Seeing many of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the formation of rescue teams throughout the UK – 274 groups are officially listed with a countrywide program. These groups pick up toads and transport them over streets in containers, as well as recording the quantity of toads they find and advocating for other safety solutions, such as road closures and amphibian passages.

Volunteers tend to operate during the breeding period, when toad crossings are frequent. However, this implies they can miss groups of young toads, which, having been eggs and then tadpoles, exit their water habitats over an unpredictable schedule in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by car traffic." And as being hit "essentially crushes them," it's harder to collect information on them. At least when mature amphibians are killed, their carcasses can be tallied.

Annual Work

In contrast to many groups, a specific volunteer group, who are in their eighth year of operating, go out throughout the year – not every night, but when conditions are damp, or if someone has reported 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 begun and it's been a dry day – but a few of the volunteers gamely agree to walk up and down their area with me and search for any toads. "If anyone can find any toads tonight, that pair will spot one," says the patrol manager, pointing to her teenage child and the experienced member. After for 120 minutes without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some wood.

Family Involvement

The family duo joined the patrol a while back. The teenager adores all things nature-related and has an ambition to become a environmentalist, so his parent started to look for things they could do together to help native animals. Now she loves it as much as he does, the middle-aged small business owner tells me – so when the group was looking for a fresh coordinator lately, she decided to step up.

The teenager, 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 authority agreed to an "access-only" rule between 5pm and 5am from February through to April. The majority of motorists duly avoided the road.

Other Wildlife and Difficulties

Several cars go by when I'm out on duty 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 moves in his palms. Yet in spite of the team's hardest attempts to show me a toad, the local population has clearly gone dormant for the colder months. It appears that I couldn't have found any better success elsewhere in the nation – all the rescue teams I reach out to clarify that it's very difficult at this time of year.

This team anticipates assisting around ten thousand mature toads over the street

One email 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, reaches me with the subject line: "No toads." However, in late winter, he informs me, the team expects to help around 10,000 mature amphibians over the street.

Effectiveness and Limitations

What level of impact 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 reduce the drop, they cannot prevent it entirely – partly since vehicles is just one danger.

Other Dangers

The global warming has resulted in longer periods of dry weather, which cause the wrong conditions for some of the animals that toads consume, such as invertebrates, while higher water temperatures have led to an increase of toxic plants, which can be toxic to toads. Milder winters also lead toads to wake up from their dormancy more frequently, interfering with the energy conservation crucial to their existence. Loss of environment – especially the loss of large ponds – is an additional threat.

Experts are "always a bit worried about putting too much of a utilitarian spin on biodiversity," but "There is a big value in just having these animals around." But toads do have an significant part in the ecosystem, consuming pretty much any invertebrates or tiny organisms they can swallow and in turn feeding a variety of birds and mammals, such as wildlife. Improving situations for toads – such as creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Cultural Significance

Another reason to try to keep toads present is their "important cultural value," adds an specialist. Legends and tales around toads date back {centuries|hundred
