Can Britain's Toads Survive from Traffic and Terrible Decline?

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

A Worrying Drop in Population

The Bufo bufo is becoming increasingly uncommon. A recent research led by an wildlife conservation group showed that the UK toad population have almost halved since 1985. Seeing a species that has been a stalwart of the British countryside in decline is labeled "concerning" by experts. Toads "don't require very specific conditions" and "should be able to live quite well in most of areas in the UK," meaning if even they are struggling to persist, "it indicates that things are not as they should be."

The Threat from Traffic

Though the study didn't cover the causes for the decline, traffic is a major factor. Calculations indicate that 20 tonnes of toads are killed on UK roads annually – in other words, several hundred thousand. In contrast to frogs, which would probably be happy to mate "if you left out a bucket of water," toads favor large ponds. Their capacity to remain away from water for more time than frogs means they can travel further to find them – sometimes long distances. They usually follow their ancestral migration routes – it's typical for adult toads to return to their natal pond to mate.

Breeding Habits

Fittingly, the first toads start their journey for a mate around Valentine's day, but some move as late as April, until it gets dark and moving after sunset. During that time, toads start moving from where they have been overwintering "all pretty much at the same time."

A local helper, who grew up in the area 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.

Rescue Groups Across the United Kingdom

Finding many of dead toads on nearby streets "resonates deeply with people," and has led to the creation of toad patrols throughout the UK – 274 groups are currently registered with a countrywide program. These groups collect toads and carry them over streets in containers, as well as counting the number of toads they encounter and lobbying for other protection measures, such as road closures and amphibian passages.

Volunteers tend to operate during the breeding period, when amphibian movements are frequent. However, this implies they can overlook groups of toadlets, which, having existed as eggs and then juveniles, leave their ponds over an irregular timetable in the end of summer. Because of their small stature – just one or two centimetres wide – "they are destroyed by car traffic." And as being hit "essentially crushes them," it's more difficult to get data on them. At least when mature amphibians are lost, their remains can be counted.

Year-Round Efforts

In contrast to most patrols, one local team, who are in their eighth year of operating, go out throughout the year – not nightly, but when conditions are damp, or if someone has posted about a amphibian spotting in their group chat. When I request to accompany them on patrol, they admit it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but several of the helpers gamely agree to walk up and down their route with me and see what we can find. "If anyone can locate any toads tonight, those two will spot one," says the group coordinator, indicating her 14-year-old son and the longtime volunteer. After for two hours without a glimpse of any amphibians, and now they have scaled a barbed wire fence to inspect beneath some logs.

Community Participation

The mother and son joined the group a while back. The youngster loves all things wildlife and has an ambition to become a conservationist, so his mother started to search for things they could do jointly to help native animals. Now she enjoys it as much as he does, the 41-year-old entrepreneur tells me – so when the group was looking for a fresh coordinator recently, she decided to step up.

The youth, too, has been instrumental in the organization. A video he made, urging the local council to block a road through a protected area during migration season, influenced the outcome the team's way. After a year of campaigning, the authority approved an "access-only" restriction between evening and morning from February through to April. Most drivers duly avoided the route.

Additional Species and Challenges

Several cars go past when I'm out on patrol and we find some victims as a consequence – no toads, but three squashed newts. We spot one live amphibian as well, and the teenager is particularly pleased to see a daddy longlegs, which dances in his palms. Yet despite the team's hardest attempts to let me see a toad, the local population has clearly gone dormant for the winter. It appears that I couldn't have found any better success anywhere else in the nation – all the patrol groups I contact explain that it's near-impossible at this season.

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

A message I receive from another volunteer, who has kindly made the effort to look for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the title: "None found." However, in February and March, he tells me, the team expects to help approximately 10,000 adult toads over the street.

Effectiveness and Challenges

What level of impact can these groups actually make? "The fact that people are doing this regularly on chilly, wet and miserable evenings is quite extraordinary," says an researcher. "That's something that very much should be celebrated." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – partly since traffic is not the only threat.

Other Dangers

The global warming has resulted in longer periods of drought, which cause the wrong conditions for some of the creatures that toads consume, such as invertebrates, while warmer ponds have caused an increase of toxic plants, which can be toxic to toads. Milder winters also lead toads to wake up from their hibernation more frequently, interfering with the resource preservation crucial to their life cycle. Loss of environment – especially the disappearance of big water bodies – is another menace.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," but "There is a big value in just their presence." But toads do have an important role in the food chain, consuming pretty much any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a number of birds and mammals, such as wildlife. Enhancing situations for toads – such as building water habitats, conserving woodland and installing toad tunnels – "we'll improve them for a wide range of other species."

Cultural Importance

Another reason to work to preserve toads around is their "important cultural value," notes an expert. Myths and folklore around toads go back {centuries|hundred
