It's a Friday evening at 7:30, but instead of heading to the pub or relaxing at home, I've caught a train to a market town in the countryside to meet up with local helpers from a amphibian rescue group. These dedicated individuals give up their evenings to safeguard the native amphibian community.

A Worrying Decline in Population

The common toad is growing more uncommon. A latest research conducted by an wildlife conservation group showed that the British common toad numbers have dropped by half since 1985. Observing a creature that has been a fixture of the UK landscape in decline is described as "worrying" by experts. Toads "don't need very specific conditions" and "should be able to live successfully in most of areas in the UK," meaning if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

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

The Threat from Roads

Though the study didn't cover the reasons for the decline, traffic certainly plays a part. Estimates indicate that 20 tons of toads are killed on UK roads every year – that is, several hundred thousand. In contrast to frogs, which might be content to mate "if you left out a small container," toads prefer big bodies of water. Their ability to remain away from water for longer than frogs means they can journey farther to reach them – often long distances. They tend to stick to their traditional paths – it's common for mature amphibians to go back to their birth pond to mate.

Migration Habits

Appropriately enough, the initial amphibians begin their quest for a partner around Valentine's day, but some move as late as spring, until it gets night and moving through the night. During that period, toads start moving from wherever they have been overwintering "almost simultaneously."

One volunteer, who was raised in the area and has been working to save its toad population since he was a child, explains that "Their sole purpose: to go and have an orgy." If their route crosses a road, they could be killed by traffic, and that mating period would be lost – preventing a new generation of toads from being produced.

Toad Patrols Throughout the UK

Finding many of toad carcasses on nearby streets "resonates deeply with people," and has led to the creation of toad patrols across the UK – hundreds of organizations are currently registered with a national initiative. These teams collect toads and carry them over streets in containers, as well as recording the quantity of toads they encounter and lobbying for other safety solutions, such as road closures and amphibian passages.

Patrols tend to operate during the breeding period, when toad crossings are more regular. However, this implies they can miss groups of young toads, which, having been eggs and then juveniles, exit their ponds over an unpredictable schedule in the end of summer. Because of their small stature – just one or two centimetres 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 adult toads are killed, their remains can be counted.

Year-Round Work

Unlike many groups, one local team, who are in their eighth season of operating, go out year-round – not every night, but whenever weather are warm and wet, or if someone has posted about a toad sighting in their group chat. When I ask to join them on patrol, they admit it is "not ideal conditions" – toad hibernation season has started and it's been a arid period – but a few of the helpers gamely agree to walk up and down their area with me and search for any toads. "If anyone can find any toads tonight, those two will find one," says the patrol manager, pointing to her teenage child and the experienced member. After for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to check under some wood.

Family Involvement

The family duo became part of the patrol a year and a half ago. The teenager loves all things nature-related and has an goal to become a conservationist, so his mother started to search for things they could do jointly to help local wildlife. Now she loves it as much as he does, the 41-year-old entrepreneur explains – so when the group was looking for a fresh coordinator lately, she volunteered for the role.

The youth, too, has played an important role in the organization. A clip he created, imploring the local council to close a street through a protected area during migration season, influenced the outcome the group's way. After a year of campaigning, the authority approved an "access-only" rule between evening and morning from late winter through to April. The majority of motorists duly avoided the road.

Additional Species and Challenges

Several vehicles go by when I'm out on duty and we find some casualties as a consequence – no toads, but several crushed salamanders. We see one live amphibian as well, and the youngster is especially excited to see a daddy longlegs, which dances in his palms. Yet despite the team's best efforts to let me see a toad, the local population has obviously settled down for the colder months. It appears that I couldn't have found any better success anywhere else in the country – all the patrol groups I contact clarify that it's very difficult at this time of year.

The group expects to help approximately 10,000 adult toads across the road

A message I receive from another volunteer, who has generously made the effort to look for toads in a famous site, considered the biggest tracked toad group in the UK, arrives in my inbox with the subject line: "No toads." However, in late winter, he tells me, the group expects to help around ten thousand adult toads across the road.

Impact and Limitations

How much of a difference can these groups truly achieve? "The reality that volunteers are performing this regularly on chilly, wet and miserable late nights is quite extraordinary," notes an expert. "This effort that very much deserves recognition." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – not least because traffic is not the only threat.

Additional Threats

The global warming has meant extended spells of drought, which create the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have led to an rise of toxic plants, which can be harmful to toads. Milder winters also lead toads to wake up from their dormancy more often, disrupting the energy conservation crucial to their existence. Habitat destruction – particularly the loss of large ponds – is an additional threat.

Experts 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 ecosystem, consuming almost any invertebrates or small animals they can swallow and in turn feeding a number of birds and mammals, such as wildlife. Enhancing conditions for toads – such as building water habitats, conserving woodland and installing amphibian passages – "benefits for a whole bunch of additional wildlife."

Historical Significance

An additional motive to work to preserve toads present is their "important cultural value," notes an expert. Myths and folklore around toads date back {centuries|hundred
