It's a Friday night at 7:30, but instead of going out or relaxing at home, I've caught a train to a market town in Wiltshire to join volunteers from a amphibian rescue group. These dedicated individuals sacrifice their evenings to protect the local toad population.

A Worrying Decline in Population

The common toad is growing more rare. A recent research conducted by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since 1985. Observing a species that has been a stalwart of the UK landscape in decrease is described as "concerning" by experts. Toads "don't need very particular environments" and "should be able to live successfully in the majority of areas in the UK," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."

The UK toad population has almost halved since 1985

The Danger from Roads

Though the study didn't examine the reasons for the drop, cars certainly plays a part. Estimates suggest that 20 tons of toads are killed on UK roads every year – that is, several hundred thousand. In contrast to frogs, which might be happy to mate "if you left out a bucket of water," toads favor large ponds. Their capacity to stay out of water for more time than frogs allows they can travel further to reach them – sometimes long distances. They usually follow their traditional paths – it's typical for mature amphibians to return to their birth pond to mate.

Migration Habits

Fittingly, the first toads start their journey for a partner around February 14th, but others travel as late as April, until it gets dark and moving through the night. During that time, toads start moving from where they have been overwintering "all pretty much at the same time."

A local helper, who was raised in the area and has been trying to protect its amphibians since he was a boy, notes that "Their sole purpose: to go and mate." If their route happens to a road, they could be killed by traffic, and that breeding season would be lost – stopping a new generation of toads from being produced.

Toad Patrols Throughout the UK

Seeing hundreds of dead toads on local roads "resonates deeply with people," and has resulted in the formation of toad patrols across the UK – hundreds of organizations are officially listed with a national initiative. These groups pick up toads and transport them across roads in buckets, as well as recording the quantity of toads they encounter and lobbying for other protection measures, such as blocked roads and amphibian passages.

Patrols usually work during the breeding period, when toad crossings are frequent. However, this means they can overlook numbers of toadlets, which, having been spawn and then tadpoles, exit their water habitats over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "basically turns them into mush," it's more difficult to collect information on them. At least when mature amphibians are lost, their remains can be counted.

Annual Work

Unlike many groups, a specific volunteer group, who are in their eighth season of operating, go out year-round – not nightly, but when weather are warm and wet, or if someone has reported about a toad sighting in their group chat. When I ask to join them on duty, they admit it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but several of the helpers willingly accept to patrol their route with me and see what we can find. "Should anyone can locate any toads tonight, those two will find one," says the patrol manager, pointing to her teenage child and the longtime volunteer. After for two hours without a single toad sighting, and now they have scaled a wire barrier to check under some logs.

Community Involvement

The family duo became part of the patrol a while back. The teenager loves all things wildlife and has an goal to become a conservationist, so his parent started to look for things they could do jointly to help local wildlife. Now she loves it as much as he does, the 41-year-old small business owner tells me – so when the group was looking for a fresh coordinator lately, she volunteered for the role.

The teenager, too, has played an important role in the organization. A clip he made, imploring the local council to block a street through a nature reserve during migration season, influenced the outcome the team's way. After a twelve months of campaigning, the authority agreed to an "restricted access" restriction between 5pm and 5am from February through to April. The majority of motorists duly avoided the route.

Additional Species and Challenges

Several cars go past when I'm out on duty and we discover some casualties as a result – no amphibians, but several crushed salamanders. We see one live amphibian as well, and the teenager is especially excited to see a harvestman, which dances in his hands. Yet despite the group's hardest attempts to let me see a toad, the local population has clearly gone dormant for the winter. It seems that I couldn't have found any better success elsewhere in the country – all the patrol groups I contact clarify that it's near-impossible at this time of year.

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

A message I receive from a different helper, who has generously taken the trouble to check for toads in a famous site, thought to be the biggest tracked toad population in the UK, reaches me with the subject line: "No toads." However, in late winter, he tells me, the team expects to help around 10,000 adult toads over the street.

Impact and Limitations

How much of a difference can these organizations actually make? "The reality that people are doing this consistently on chilly, wet and miserable evenings is remarkable," says an expert. "That's something 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 just one danger.

Additional Threats

The climate crisis has meant extended spells of dry weather, which create the wrong conditions for some of the animals that toads consume, such as worms and slugs, while higher water temperatures have caused 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 vital to their existence. Loss of environment – particularly the loss of big water bodies – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on wildlife," but "There is a big value in just having these animals around." But toads do have an important role in the food chain, 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. Enhancing conditions for toads – such as building water habitats, protecting forests and installing amphibian passages – "benefits for a wide range of additional wildlife."

Historical Importance

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