It is a Friday evening at half past seven, but instead of going out or relaxing at home, I've taken a train to a town in the countryside to join local helpers from a toad patrol. These dedicated individuals give up their nights to safeguard the local toad population.

A Worrying Drop in Population

The Bufo bufo is growing more rare. A latest research led by an wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Observing a species that has been a stalwart of the UK landscape in decrease is described as "worrying" by experts. Toads "don't require very specific conditions" and "ought to live successfully in most of habitats in Britain," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."

The Threat from Roads

Though the research didn't cover the causes for the decline, cars is a major factor. Estimates indicate that 20 tons of toads are killed on British roads every year – that is, hundreds of thousands. In contrast to frogs, which would probably be happy to mate "if you left out a bucket of water," toads favor big bodies of water. Their ability to remain away from water for more time than frogs means they can travel further to find them – sometimes hundreds of metres. They tend to stick to their ancestral migration routes – it's typical for adult toads to return to their natal pond to mate.

Breeding Habits

Fittingly, the initial amphibians start their journey for a mate around Valentine's day, but others travel as far as spring, until it gets night and travelling after sunset. During that period, toads start moving from wherever they have been hibernating "all pretty much at the same time."

A local helper, who grew up in the area and has been working to save its toad population since he was a child, notes that "Their sole purpose: to go and have an orgy." If their path happens to a road, they could all get run over, and that mating period would never happen – stopping a next generation of toads from being produced.

Toad Patrols Throughout the UK

Finding many of dead toads on nearby streets "resonates deeply with people," and has led to the creation of toad patrols across the UK – 274 groups are officially listed with a national initiative. These groups pick up toads and transport them across roads in buckets, as well as counting the quantity of toads they find and lobbying for other protection measures, such as blocked roads and underground wildlife tunnels.

Volunteers usually work during the migration season, when toad crossings are more regular. However, this implies they can miss groups of young toads, which, having existed as spawn and then tadpoles, leave their ponds over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." And as being hit "essentially crushes them," it's harder to get data on them. At least when adult toads are lost, their remains can be tallied.

Year-Round Efforts

Unlike many groups, one local team, who are in their eighth year of operating, go out year-round – not every night, but when conditions are damp, or if someone has reported about a toad sighting in their messaging app. When I ask to join them on duty, they admit it is "not ideal conditions" – toad hibernation season has begun 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 see what we can find. "Should anyone can find any toads tonight, that pair will spot one," says the patrol manager, indicating her teenage child and the longtime volunteer. After for two hours without a single toad sighting, and now they have climbed over a wire barrier to check under some logs.

Family Involvement

The mother and son joined the patrol a year and a half ago. The teenager adores all things wildlife and has an goal to become a conservationist, so his mother started to look for activities they could do jointly to protect native animals. Now she loves it as much as he does, the 41-year-old small business owner explains – so when the team was looking for a fresh coordinator lately, she volunteered for the role.

The youth, too, has played an important role in the group. A clip he created, urging the local council to close a street through a nature reserve during migration season, influenced the outcome the team's way. After a year of campaigning, the council agreed to an "access-only" restriction between evening and morning from late winter through to spring. Most drivers respected and avoided the route.

Other Wildlife and Difficulties

Several vehicles go past when I'm out on patrol and we find some casualties as a consequence – no toads, but three squashed newts. We spot one living newt as well, and the youngster is especially excited to see a daddy longlegs, which dances in his palms. Yet in spite of the team's hardest attempts to show me a toad, the local population has obviously settled down for the winter. It appears that I wouldn't have had any better success anywhere else in the country – all the patrol groups I reach out to explain that it's near-impossible at this time of year.

One email I receive from a different helper, who has kindly made the effort to check for toads in a noted location, thought to be 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 group expects to help around ten thousand adult toads across the road.

Effectiveness and Limitations

What level of impact can these groups truly achieve? "The fact that volunteers are performing this consistently on chilly, wet and miserable late nights is remarkable," notes an expert. "That's something that very much should be celebrated." However, while rescue teams are able to reduce the drop, they can't stop it completely – not least because traffic is just one danger.

Other Dangers

The climate crisis has resulted in longer periods 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. Milder winters also cause toads to emerge from their dormancy more often, disrupting the energy conservation vital to their existence. Habitat destruction – especially the disappearance of large ponds – is an additional threat.

Researchers are "often concerned about putting too much of a utilitarian spin on biodiversity," however "It's important in just their presence." But toads do have an important role in the ecosystem, consuming almost any small creatures or tiny organisms they can swallow and in turn feeding a variety of predators, such as wildlife. Enhancing situations for toads – ie creating more ponds, protecting forests and constructing toad tunnels – "we'll improve them for a whole bunch of other species."

Cultural Significance

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