Can the UK's Common Toads Survive from Roads and Population Collapse?

It's Friday evening at half past seven, but rather than going out or watching a film, I've caught a train to a town in Wiltshire to join local helpers from a amphibian rescue group. These dedicated individuals give up their evenings to safeguard the local toad population.

A Worrying Drop in Population

The common toad is growing more rare. A latest research conducted by an wildlife conservation group revealed that the UK toad population have almost halved since 1985. Seeing a creature that has been a fixture of the UK landscape in decline is labeled "concerning" by researchers. Toads "don't need very particular environments" and "ought to live successfully in the majority of habitats in the UK," so if even they are not managing to survive, "it indicates that things are not as they should be."

The Danger from Traffic

Though the study didn't examine the reasons for the decline, cars certainly plays a part. Calculations indicate that 20 tonnes of toads are killed on British roads every year – that is, hundreds of thousands. In contrast to frogs, which might be content to mate "with just a small container," toads favor large ponds. Their capacity to stay out of water for more time than frogs allows they can travel further to find them – sometimes long distances. They tend to stick to their ancestral migration routes – it's typical for mature amphibians to go back to their natal pond to mate.

Breeding Patterns

Appropriately enough, the first toads begin their quest for a mate around February 14th, but others travel as far as April, waiting until it gets night and travelling after sunset. During that time, toads begin migrating 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 trying to protect 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 – preventing a next generation of toads from being born.

Rescue Groups Throughout the UK

Seeing hundreds of dead toads on nearby streets "resonates deeply with people," and has resulted in the creation of rescue teams across the UK – 274 groups are currently registered with a countrywide program. These teams collect toads and carry them across roads in buckets, as well as counting the quantity of toads they encounter and advocating for other safety solutions, such as blocked roads and amphibian passages.

Patrols tend to operate during the breeding period, when amphibian movements are frequent. However, this implies they can miss numbers of young toads, which, having existed as eggs and then juveniles, exit their ponds over an irregular timetable in late summer. Because of their small stature – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "essentially crushes them," it's more difficult to get data on them. At least when mature amphibians are lost, their remains can be tallied.

Annual Work

Unlike many groups, one local team, who are in their eighth season of functioning, go out year-round – not nightly, but when weather are damp, or if a member has reported about a amphibian spotting in their messaging app. When I ask to join them on duty, they admit it is "not a toady night" – toad hibernation season has started 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. "Should 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 climbed over a barbed wire fence to check under some wood.

Family Involvement

The family duo joined the group a while back. The youngster loves all things nature-related and has an goal to become a conservationist, so his mother started to look for activities they could do jointly to help local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the group was looking for a fresh coordinator lately, she volunteered for the role.

The teenager, too, has been instrumental in the organization. A clip he created, urging the local council to close a street through a nature reserve during migration season, swung the decision the team's way. After a twelve months of lobbying, the authority agreed to an "restricted access" restriction between 5pm and 5am from February through to April. The majority of motorists respected and avoided the route.

Additional Species and Challenges

Several vehicles go by when I'm out on duty and we discover some victims as a consequence – no amphibians, but three squashed newts. We see one live amphibian as well, and the teenager is particularly pleased to see a daddy longlegs, which moves in his hands. Yet despite the team's best efforts to let me see a toad, the local population has obviously settled down for the winter. It seems that I wouldn't have had any more luck elsewhere in the nation – all the rescue teams I reach out to clarify that it's very difficult at this time of year.

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

One email I get from another volunteer, who has kindly taken the trouble to check for toads in a famous site, thought to be the biggest tracked toad group in the UK, reaches me with the subject line: "None found." However, in late winter, he informs me, the team plans to assist approximately ten thousand mature amphibians over the street.

Effectiveness and Limitations

How much of a difference can these organizations actually make? "The reality that volunteers are doing this regularly on chilly, wet and miserable evenings is remarkable," notes an expert. "This effort that very much should be celebrated." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since traffic is not the only threat.

Additional Threats

The global warming has meant extended spells of drought, which create the wrong conditions for some of the animals that toads eat, such as invertebrates, while warmer ponds have caused an rise of blue-green algae, which can be harmful to toads. Milder winters also lead toads to wake up from their dormancy more frequently, interfering with the resource preservation vital to their life cycle. Habitat destruction – especially the loss of big water bodies – is another menace.

Researchers are "always a bit worried about putting too much of a utilitarian spin on wildlife," however "It's important in just their presence." But toads play an important role in the food chain, eating pretty much any invertebrates or tiny organisms they can swallow and in turn feeding a variety of birds and mammals, such as wildlife. Enhancing situations for toads – ie building water habitats, conserving woodland and constructing amphibian passages – "we'll improve them for a whole bunch of additional wildlife."

Historical Significance

An additional motive to try to keep toads present is their "important cultural value," adds an specialist. Myths and folklore around toads go back {centuries|hundred
