It's a Friday night at 7:30, but rather than heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to meet up with volunteers from a toad patrol. These dedicated individuals sacrifice their nights to protect the native amphibian community.

A Worrying Decline in Population

The Bufo bufo is becoming increasingly uncommon. A recent research conducted by an wildlife conservation group revealed that the British common toad numbers have dropped by half since 1985. Seeing a species that has been a stalwart of the UK landscape in decline is described as "concerning" by researchers. Toads "don't require very particular environments" and "should be able to live successfully in the majority of areas in the UK," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The Threat from Traffic

Though the study didn't cover the reasons for the decline, traffic is a major factor. Calculations indicate that 20 tons of toads are killed on UK roads annually – in other words, several hundred thousand. In contrast to frogs, which would probably be content to mate "with just a bucket of water," toads prefer large ponds. Their capacity to remain away from water for longer than frogs allows they can journey farther to reach them – sometimes long distances. They usually follow their ancestral migration routes – it's typical for adult toads to return to their birth pond to mate.

Migration Patterns

Appropriately enough, the initial amphibians begin their quest for a mate around Valentine's day, but some move as late as April, waiting until it gets night and travelling after sunset. During that time, toads begin migrating from where they have been hibernating "almost simultaneously."

One volunteer, who grew up in the area and has been trying to protect its toad population since he was a child, notes that "Their sole purpose: to go and mate." If their path happens to a road, they could be killed by traffic, and that mating period would be lost – preventing a next generation of toads from being born.

Toad Patrols Throughout the United Kingdom

Finding many of toad carcasses on local roads "resonates deeply with people," and has led to the creation of rescue teams across the UK – 274 groups are currently registered with a national initiative. These teams collect toads and carry them over streets in buckets, as well as counting the number of toads they find and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the migration season, when toad crossings are more regular. However, this means they can miss numbers of toadlets, which, having been spawn and then juveniles, leave their water habitats over an unpredictable schedule in late summer. Because of their size – just a couple of cm wide – "they can get obliterated by car traffic." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are killed, their remains can be tallied.

Annual Efforts

In contrast to most patrols, one local team, who are in their eighth year of functioning, go out throughout the year – not nightly, but whenever weather are warm and wet, or if a member has posted about a toad sighting in their group chat. When I request to accompany them on duty, they admit it is "not a toady night" – winter dormancy has started and it's been a arid period – but several of the helpers willingly accept to walk up and down their area with me and see what we can find. "Should anyone can find any toads tonight, those two will spot one," says the group coordinator, indicating her teenage child and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have scaled a wire barrier to inspect beneath some logs.

Family Participation

The family duo joined the group a while back. The youngster loves all things nature-related and has an goal to become a environmentalist, so his parent started to look for things they could do together to protect native animals. Now she loves it as much as he does, the middle-aged entrepreneur tells me – so when the team was looking for a new manager recently, she volunteered for the role.

The teenager, too, has played an important role in the group. A clip he made, imploring the municipal authority to block a road through a nature reserve during breeding time, influenced the outcome the team's way. After a twelve months of campaigning, the authority agreed to an "access-only" restriction between 5pm and 5am from February through to spring. The majority of motorists respected and avoided the route.

Other Wildlife and Difficulties

Several vehicles go past when I'm out on duty and we find some casualties as a result – no amphibians, but three squashed newts. We see one living newt as well, and the teenager is especially excited to see a harvestman, which dances in his hands. Yet despite the team's best efforts to let me see a toad, the native community has clearly gone dormant for the winter. It seems that I wouldn't have had any better success anywhere else in the nation – all the patrol groups I reach out to explain that it's near-impossible at this season.

One email I receive from another volunteer, who has generously taken the trouble to look for toads in a noted location, considered the biggest tracked toad group in the UK, reaches me with the subject line: "None found." However, in late winter, he informs me, the group expects to help around ten thousand mature amphibians over the street.

Impact and Limitations

What level of impact can these groups truly achieve? "The reality that volunteers are performing this consistently on cold, damp and unpleasant late nights is quite extraordinary," says an expert. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – partly since traffic is just one danger.

Other Dangers

The climate crisis has resulted in longer periods of drought, which create the poor environment for some of the animals that toads eat, such as invertebrates, while warmer ponds have led to an rise of blue-green algae, which can be harmful to toads. Milder winters also lead toads to emerge from their hibernation more often, disrupting the resource preservation crucial to their existence. Loss of environment – particularly the disappearance of big water bodies – is another menace.

Experts are "often concerned about overemphasizing practical benefits on wildlife," but "There is a big value in just having these animals around." But toads play an important role in the ecosystem, consuming almost any invertebrates or small animals they can fit in their mouths and in turn feeding a number of birds and mammals, such as wildlife. Improving conditions for toads – such as creating more ponds, conserving woodland and constructing amphibian passages – "we'll improve them for a wide range of other species."

Cultural Significance

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