Can Britain's Common Toads Survive from Traffic and Population Collapse?

It is a Friday evening at 7:30, but instead of going out or watching a film, I've caught a train to a market town in the countryside to meet up with volunteers from a toad patrol. These committed people give up their nights to protect the local toad population.

An Alarming Decline in Population

The Bufo bufo is becoming increasingly rare. A latest study conducted by an amphibian and reptile charity showed that the UK toad population have almost halved since the mid-1980s. Observing a species that has been a stalwart of the UK landscape in decrease is described as "concerning" by experts. Toads "don't need very specific conditions" and "should be able to live quite well in the majority of habitats in Britain," so 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 examine the reasons for the drop, cars is a major factor. Estimates suggest that 20 tonnes of toads are killed on UK roads annually – that is, hundreds of thousands. In contrast to frogs, which might be content to mate "with just a small container," toads prefer large ponds. Their ability to remain away from water for more time than frogs allows they can journey farther to reach them – often long distances. They tend to stick to their traditional paths – it's typical for adult toads to return to their natal pond to mate.

Migration Patterns

Appropriately enough, the initial amphibians start their journey for a partner around February 14th, but some move as late as April, waiting until it gets night and moving after sunset. During that time, toads start moving from where they have been hibernating "almost simultaneously."

A local helper, who grew up in the region and has been trying to protect its toad population since he was a child, explains that "Their sole purpose: to go and have an orgy." If their path crosses a street, they could be killed by traffic, and that mating period would never happen – stopping a next generation of toads from being produced.

Toad Patrols Across the United Kingdom

Seeing many of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the formation of toad patrols across the UK – hundreds of organizations are currently registered with a countrywide program. These teams collect toads and carry them across roads in buckets, as well as recording the quantity of toads they encounter and advocating for other safety solutions, such as blocked roads and amphibian passages.

Patrols usually work during the breeding period, when amphibian movements are more regular. However, this implies they can miss groups of young toads, which, having been eggs and then tadpoles, exit their water habitats over an irregular timetable in the end of summer. Because of their size – just one or two centimetres wide – "they are destroyed by car traffic." And as being hit "essentially crushes them," it's harder to get data on them. At least when adult toads are killed, their remains can be counted.

Annual Efforts

In contrast to most patrols, one local team, who are in their eighth year of functioning, go out year-round – not nightly, but whenever conditions are warm and wet, or if someone has posted about a amphibian spotting in their messaging app. When I request to accompany 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 helpers willingly accept to patrol their area with me and see what we can find. "Should anyone can locate any toads tonight, that pair will find one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. We've been out for two hours without a single toad sighting, and now they have climbed over a wire barrier to check under some wood.

Community Participation

The mother and son joined the patrol a year and a half ago. The youngster loves all things nature-related and has an goal to become a conservationist, so his parent started to look 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 explains – so when the group was seeking a fresh coordinator recently, she volunteered for the role.

The youth, too, has played an important role in the organization. A clip he made, imploring the municipal authority 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 approved an "access-only" restriction between evening and morning from late winter through to April. The majority of motorists duly avoided the route.

Additional Species and Challenges

A few vehicles go past when I'm out on duty and we find some victims as a result – no toads, but several crushed salamanders. We see one live amphibian as well, and the teenager is particularly pleased 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 local population has obviously gone dormant for the colder months. It seems that I wouldn't have had any better success anywhere else in the nation – all the patrol groups I reach out to explain that it's very difficult at this time of year.

This team anticipates assisting around ten thousand mature toads over the street

One email I receive from a different helper, who has generously made the effort to check for toads in a noted location, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "None found." However, in February and March, he tells me, the group expects to help approximately 10,000 adult toads over the street.

Effectiveness and Challenges

How much of a difference can these organizations actually make? "The fact that volunteers are doing this regularly on chilly, wet and miserable evenings is quite extraordinary," notes an expert. "This effort that very much should be celebrated." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because traffic is just one danger.

Additional Threats

The global warming has resulted in longer periods of dry weather, which cause the wrong conditions for some of the animals that toads consume, such as invertebrates, while higher water temperatures have led to an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also lead toads to emerge from their hibernation more often, interfering with the resource preservation crucial to their existence. Loss of environment – especially the loss of big water bodies – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits on wildlife," but "There is a big value in just their presence." But toads do have an significant part in the food chain, eating pretty much any small creatures or small animals they can swallow and in turn sustaining a number of predators, such as hedgehogs and otters. Improving situations for toads – such as building water habitats, protecting forests and installing toad tunnels – "we'll improve them for a wide range of other species."

Historical Significance

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