Can the UK's Toads Survive from Roads and Terrible Decline?

It is Friday night at half past seven, but instead of heading to the pub or watching a film, I've taken a train to a market town in the countryside to join local helpers from a amphibian rescue group. These committed people sacrifice their evenings to safeguard the native amphibian community.

A Worrying Decline in Population

The common toad is growing more rare. A recent study led by an wildlife conservation group revealed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a fixture of the British countryside in decrease is labeled "concerning" by experts. Toads "don't require very specific conditions" and "should be able to live successfully in the majority of areas in Britain," so if even they are not managing to survive, "it kind of suggests that things are not as they should be."

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

The Threat from Roads

Though the research didn't cover the reasons for the drop, cars is a major factor. 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 content to mate "if you left out a small container," toads favor big bodies of water. Their ability to remain away from water for more time than frogs allows they can journey farther to reach them – sometimes hundreds of metres. They tend to stick to their ancestral migration routes – it's common for adult toads to return to their natal pond to mate.

Breeding Patterns

Fittingly, the initial amphibians start their journey for a partner around Valentine's day, but others travel as late as spring, waiting until it gets dark and moving after sunset. During that time, toads start moving from wherever they have been overwintering "all pretty much at the same time."

One volunteer, who grew up in the area and has been trying to protect its amphibians since he was a boy, explains that "Their sole purpose: to go and mate." If their route crosses a street, they could be killed by traffic, and that breeding season would be lost – stopping a next generation of toads from being produced.

Rescue Groups Across the United Kingdom

Seeing many of toad carcasses on local roads "resonates deeply with people," and has resulted in the creation of toad patrols throughout the UK – 274 groups are officially listed with a national initiative. These teams pick up toads and carry them over streets in buckets, as well as counting the quantity of toads they find and advocating for other protection measures, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the breeding period, when amphibian movements are frequent. However, this implies they can miss numbers of young toads, which, having been spawn and then tadpoles, leave their ponds over an unpredictable schedule in the end of summer. Because of their size – just one or two centimetres wide – "they are destroyed by vehicles." And as being hit "basically turns them into mush," it's harder to get data on them. At least when mature amphibians are lost, their carcasses can be tallied.

Year-Round Work

In contrast to most patrols, a specific volunteer group, who are in their eighth year of operating, go out year-round – not every night, but when weather are damp, or if someone has posted about a toad sighting in their group chat. When I ask to join them on patrol, they admit it is "not a toady night" – winter dormancy has started and it's been a arid period – but several of the volunteers gamely agree to patrol their area with me and see what we can find. "If anyone can find any toads tonight, that pair will find one," says the patrol manager, indicating her 14-year-old son and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some wood.

Community Participation

The family duo became part of the patrol a while back. The youngster adores all things wildlife and has an goal to become a environmentalist, so his parent started to look for activities they could do together to protect native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the team was looking for a new manager lately, she decided to step up.

The teenager, too, has played an important role in the group. A video he created, imploring the municipal authority to block a road through a nature reserve during breeding time, swung the decision the group's way. After a year of lobbying, the authority approved an "restricted access" restriction between 5pm and 5am from late winter through to April. The majority of motorists respected and avoided the route.

Additional Species and Difficulties

A few cars go past when I'm out on patrol and we discover some casualties as a result – no toads, 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 in spite of the team's hardest attempts to let me see a toad, the native community has clearly settled down for the colder months. It appears that I wouldn't have had any better success elsewhere in the nation – all the patrol groups I reach out to 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 a different helper, who has kindly made the effort to check for toads in a famous site, thought to be the biggest tracked toad group in the UK, reaches me with the title: "None found." However, in late winter, he tells me, the team plans to assist approximately ten thousand adult toads across the road.

Effectiveness and Limitations

What level of impact can these groups truly achieve? "The reality that volunteers are doing this consistently on chilly, wet and miserable late nights is remarkable," notes an expert. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – partly since vehicles is just one danger.

Other Dangers

The climate crisis has meant extended spells of drought, which create the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have led to an increase of toxic plants, which can be harmful to toads. Milder winters also cause toads to wake up from their dormancy more often, disrupting the energy conservation vital to their existence. Habitat destruction – particularly the loss of big water bodies – is an additional threat.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," but "There is a big value in just having these animals around." But toads do have an significant part in the food chain, consuming pretty much any invertebrates or tiny organisms they can swallow and in turn sustaining a variety of predators, such as wildlife. Enhancing conditions for toads – such as creating more ponds, conserving woodland and installing toad tunnels – "benefits for a whole bunch of other species."

Historical Importance

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