It is a Friday evening at half past seven, but instead of going out or watching a film, I've caught a train to a market town in the countryside to meet up with volunteers from a toad patrol. These committed people sacrifice their evenings to safeguard the local toad population.

An Alarming Decline in Numbers

The Bufo bufo is growing more rare. A recent research led by an amphibian and reptile charity showed that the UK toad population have dropped by half since the mid-1980s. Seeing a species that has been a fixture of the UK landscape in decline is labeled "concerning" by researchers. Toads "don't need very particular environments" and "should be able to live quite well in most of habitats in the UK," meaning if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

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

The Danger from Roads

Though the research didn't examine the causes for the decline, traffic certainly plays a part. Estimates suggest that 20 tons of toads are crushed on British roads every year – in other words, several hundred thousand. Unlike frogs, which would probably be content to mate "if you left out a bucket of water," toads favor large ponds. Their ability to remain away from water for more time than frogs allows they can travel further to reach them – often hundreds of metres. They tend to follow their traditional paths – it's typical for mature amphibians to go back to their natal pond to mate.

Migration Patterns

Appropriately enough, the initial amphibians start their journey for a mate around February 14th, but some move as far as April, until it gets night and travelling after sunset. During that period, toads begin migrating from where they have been overwintering "all pretty much at the same time."

One volunteer, who was raised in the area and has been trying to protect its toad population since he was a boy, notes that "They've got just one focus: to go and mate." If their path happens to a road, they could all get run over, and that breeding season would never happen – stopping a next generation of toads from being born.

Toad Patrols Throughout the UK

Finding hundreds of toad carcasses on nearby streets "inherently strikes a chord with people," and has resulted in the creation of rescue teams throughout the UK – 274 groups are officially listed with a national initiative. These teams pick up toads and carry them over streets in buckets, as well as recording the number of toads they find and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Volunteers tend to operate during the breeding period, when amphibian movements are frequent. However, this implies they can overlook groups of young toads, which, having existed as spawn and then tadpoles, leave their ponds over an irregular timetable 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 run over "essentially crushes them," it's harder to get data on them. At least when adult toads are killed, their remains can be counted.

Annual Efforts

Unlike most patrols, one local team, who are in their eighth season of functioning, go out throughout the year – not every night, but when weather are warm and wet, or if a member has reported about a amphibian spotting in their messaging app. When I ask to join them on duty, 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 patrol their area with me and see what we can find. "Should anyone can locate any toads tonight, those two will find one," says the patrol manager, indicating her teenage child and the longtime volunteer. We've been out for two hours without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some wood.

Community Participation

The mother and son 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 look for activities they could do together to help local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur tells me – so when the team was looking for a new manager recently, she decided to step up.

The youth, too, has played an important role in the organization. A video he made, imploring the local council to close a road through a nature reserve during migration season, swung the decision the group's way. After a twelve months of lobbying, the council approved an "restricted access" rule between 5pm and 5am from late winter through to April. Most drivers respected and avoided the road.

Additional Species and Challenges

A few vehicles go past when I'm out on patrol and we discover 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 daddy longlegs, which dances in his hands. Yet despite the group's hardest attempts to let me see a toad, the local population has clearly settled down for the winter. It seems that I wouldn't have had any more luck anywhere else in the country – all the rescue teams I contact clarify that it's near-impossible at this time of year.

They project rescuing nearly 10,000 grown amphibians during migration

A message I get from a different helper, who has generously made the effort to check for toads in a famous site, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "None found." However, in late winter, he informs me, the group plans to assist approximately 10,000 mature amphibians across the road.

Impact and Limitations

How much of a difference can these groups actually make? "The reality that people are doing this consistently on chilly, wet and miserable late nights is remarkable," says an researcher. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, 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 poor environment for some of the creatures that toads consume, such as invertebrates, while higher water temperatures have led to an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also lead toads to wake up from their hibernation more often, interfering with the resource preservation crucial to their life cycle. Loss of environment – especially the loss of big water bodies – is an additional threat.

Experts are "always a bit worried about putting too much of a utilitarian spin on wildlife," however "It's important in just their presence." But toads play an significant part in the ecosystem, eating almost any invertebrates or tiny organisms they can fit in their mouths and in turn sustaining a variety of birds and mammals, such as wildlife. Improving conditions for toads – such as creating more ponds, conserving woodland and constructing amphibian passages – "benefits for a whole bunch of other species."

Historical Importance

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