It's a Friday evening at half past seven, but rather than heading to the pub or relaxing at home, I've caught a train to a town in the countryside to join volunteers from a toad patrol. These committed people sacrifice their nights to safeguard the native amphibian community.

A Worrying Decline in Numbers

The common toad is becoming increasingly rare. A latest study led by an wildlife conservation group showed that the British common toad numbers have almost halved since 1985. Seeing a creature that has been a fixture of the British countryside in decline is described as "worrying" by researchers. Toads "don't require very particular environments" and "ought to live quite well in the majority of habitats in Britain," meaning if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

Since 1985, Britain's toad numbers have nearly been cut in half

The Danger from Traffic

Though the study didn't cover the reasons for the decline, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are crushed on UK roads annually – that is, several hundred thousand. Unlike frogs, which might be happy to mate "with just a small container," toads favor large ponds. Their ability to remain away from water for more time than frogs means they can journey farther to find them – sometimes hundreds of metres. They usually stick to their traditional paths – it's typical for adult toads to go back to their natal pond to mate.

Breeding Patterns

Fittingly, the initial amphibians start their journey for a partner around February 14th, but others travel as far as April, until it gets night and travelling after sunset. During that time, toads begin migrating from wherever they have been overwintering "almost simultaneously."

A local helper, who grew up in the region and has been working to save its amphibians since he was a child, explains 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 mating period would be lost – preventing a new generation of toads from being produced.

Toad Patrols Across the United Kingdom

Seeing many of toad carcasses on local roads "resonates deeply with people," and has led to the creation of toad patrols throughout the UK – hundreds of organizations are officially listed with a national initiative. These teams pick up toads and transport them over streets in containers, as well as recording the quantity of toads they encounter and advocating for other protection measures, such as blocked roads and amphibian passages.

Patrols tend to operate during the migration season, when toad crossings are frequent. However, this means they can miss groups of young toads, which, having existed as spawn and then juveniles, leave their water habitats over an unpredictable schedule in the end of summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by vehicles." And as being run over "essentially crushes them," it's harder to get data on them. At least when mature amphibians are lost, their remains can be tallied.

Year-Round Work

In contrast to most patrols, a specific volunteer group, who are in their eighth season of functioning, go out year-round – not every night, but whenever conditions are damp, or if someone has reported about a toad sighting in their messaging app. When I ask to join them on patrol, they admit it is "not ideal conditions" – toad hibernation season has begun and it's been a dry day – but several of the volunteers willingly accept to patrol their route with me and see what we can find. "If anyone can find any toads tonight, those two will spot one," says the group coordinator, pointing to her teenage child and the experienced member. After for 120 minutes without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some logs.

Family Participation

The family duo joined the patrol a year and a half ago. The teenager loves all things wildlife and has an ambition to become a environmentalist, so his parent started to search for things they could do jointly to help native animals. Now she loves it as much as he does, the 41-year-old small business owner tells me – so when the team was seeking a fresh coordinator lately, she decided to step up.

The teenager, too, has been instrumental in the group. A clip he created, imploring the municipal authority to block a street through a nature reserve during breeding time, swung the decision the group's way. After a twelve months of lobbying, the council agreed to an "access-only" restriction between 5pm and 5am from February through to April. Most drivers duly avoided the route.

Additional Species and Challenges

A few cars go by when I'm out on patrol and we discover some casualties as a result – no amphibians, but several crushed salamanders. We spot one live amphibian as well, and the youngster is especially excited to see a daddy longlegs, which dances in his palms. Yet in spite of the group's best efforts to show me a toad, the local population has obviously settled down for the colder months. It seems that I wouldn't have had any more luck elsewhere in the nation – all the patrol groups I contact explain that it's near-impossible at this season.

They project rescuing nearly 10,000 grown amphibians during migration

One email I receive from a different helper, who has kindly taken the trouble to look for toads in a famous site, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he tells me, the team plans to assist approximately 10,000 adult toads over the street.

Effectiveness and Challenges

What level of impact can these groups actually make? "The reality that volunteers are doing this consistently on chilly, wet and miserable evenings is remarkable," notes an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – not least because vehicles is not the only threat.

Additional Threats

The global warming has resulted in longer periods of drought, which cause the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have caused an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also lead toads to emerge from their hibernation more frequently, disrupting the resource preservation crucial to their existence. Habitat destruction – particularly the loss of big water bodies – is an additional threat.

Researchers are "often concerned about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just their presence." But toads play an important role in the ecosystem, eating pretty much any invertebrates or tiny organisms they can swallow and in turn feeding a number of birds and mammals, such as hedgehogs and otters. Improving situations for toads – such as creating more ponds, protecting forests and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Cultural Importance

Another reason to try to keep toads around is their "important cultural value," notes an specialist. Myths and folklore around toads date back {centuries|hundred
