It is 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 meet up with volunteers from a toad patrol. These committed people give up their evenings to protect the native amphibian community.

A Worrying Decline in Population

The common toad is growing more rare. A recent study conducted by an wildlife conservation group showed that the UK toad population have dropped by half since the mid-1980s. Seeing a creature that has been a stalwart of the British countryside in decrease is described as "worrying" by researchers. Toads "don't need very specific conditions" and "should be able to live quite well in most of habitats in the UK," meaning if even they are struggling to persist, "it indicates that things are not as they should be."

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

The Threat from Roads

Though the study didn't cover the causes for the drop, cars is a major factor. Estimates suggest that 20 tons of toads are crushed on UK roads annually – in other words, hundreds of thousands. Unlike frogs, which would probably be content to mate "if you left out a small container," toads favor big bodies of water. 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 common for adult toads to go back to their birth pond to mate.

Breeding Patterns

Fittingly, the first toads begin their quest for a partner around Valentine's day, but others travel as far as spring, waiting until it gets night and moving through the night. During that time, toads start moving from where they have been overwintering "almost simultaneously."

A local helper, who was raised in the region and has been working to save its amphibians since he was a child, notes that "They've got just one focus: to go and have an orgy." If their route crosses a street, they could all get run over, and that breeding season would never happen – stopping a new generation of toads from being produced.

Toad Patrols Across the United Kingdom

Seeing hundreds of dead toads on nearby streets "resonates deeply with people," and has resulted in the creation of toad patrols across the UK – hundreds of organizations are officially listed with a national initiative. These teams pick up toads and transport them over streets in buckets, as well as counting the number of toads they encounter and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Volunteers usually work during the migration season, when toad crossings are more regular. However, this means they can miss numbers of toadlets, which, having existed as spawn and then juveniles, exit their water habitats over an irregular timetable in the end of summer. Because of their small stature – 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 lost, their carcasses can be counted.

Annual Work

Unlike most patrols, a specific volunteer group, who are in their eighth season of operating, go out year-round – not nightly, but when weather are damp, or if someone has reported about a toad sighting in their group chat. When I ask to join them on patrol, they concede it is "not a toady night" – toad hibernation season has started and it's been a dry day – but a few of the volunteers gamely agree to patrol their route with me and see what we can find. "Should anyone can find any toads tonight, that pair 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 barbed wire fence to inspect beneath some logs.

Community Participation

The mother and son became part of the patrol a year and a half ago. The youngster loves all things nature-related and has an goal to become a conservationist, so his parent started to search for activities they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the 41-year-old small business owner explains – so when the team was seeking a new manager lately, she decided to step up.

The teenager, too, has been instrumental 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 team's way. After a year of campaigning, the council agreed to an "restricted access" rule between evening and morning from late winter through to spring. Most drivers duly avoided the route.

Additional Species and Challenges

A few vehicles go by when I'm out on duty and we find some victims as a result – no toads, but three squashed newts. We spot one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which moves in his palms. Yet in spite of the team's best efforts to show me a toad, the native community has obviously settled down for the winter. It seems that I wouldn't have had any more luck anywhere else in the country – all the patrol groups I contact clarify that it's near-impossible at this season.

They project rescuing nearly 10,000 grown amphibians during migration

A message I receive from another volunteer, who has generously made the effort 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 February and March, he tells me, the team plans to assist approximately ten thousand mature amphibians across the road.

Impact and Challenges

What level of impact can these organizations actually make? "The reality that people are doing this regularly on chilly, wet and miserable evenings is remarkable," says an researcher. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because traffic is not the only threat.

Other Dangers

The global warming has meant extended spells of dry weather, which create the poor environment for some of the animals that toads consume, such as invertebrates, while warmer ponds have caused an rise of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to wake up from their hibernation more frequently, interfering with the resource preservation crucial to their life cycle. Loss of environment – especially the loss of large ponds – is another menace.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," however "It's important in just having these animals around." But toads do have an important role in the ecosystem, consuming almost any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a variety of birds and mammals, such as wildlife. Enhancing conditions for toads – ie creating more ponds, conserving woodland and installing amphibian passages – "we'll improve them for a whole bunch of other species."

Cultural Importance

An additional motive to work to preserve toads present is their "historical significance," adds an specialist. Legends and tales around toads go back {centuries|hundred
