Will the UK's Toads Survive from Roads and Population Collapse?
It's Friday night at half past seven, but rather than going out or relaxing at home, I've taken a train to a market town in the countryside to meet up with local helpers from a amphibian rescue group. These committed people sacrifice their nights to protect the local toad population.
An Alarming Drop in Numbers
The common toad is becoming increasingly uncommon. A recent research conducted by an wildlife conservation group showed that the UK toad population have dropped by half since 1985. Observing a creature that has been a fixture of the UK landscape in decrease is labeled "worrying" by experts. Toads "don't need very particular environments" and "ought to live successfully in the majority of areas in the UK," so if even they are struggling to persist, "it indicates that things are not as they should be."
Toad populations across the UK have declined by almost 50% since the 1980s
The Threat from Roads
Though the study didn't examine the reasons for the drop, traffic is a major factor. Estimates suggest that 20 tonnes of toads are killed on UK roads every year – that is, several hundred thousand. In contrast to frogs, which would probably be content to mate "with just a bucket of water," toads favor large ponds. Their ability to stay out of water for longer than frogs allows they can journey farther to reach them – sometimes long distances. They tend to follow their traditional paths – it's typical for mature amphibians to return to their birth pond to mate.
Breeding Patterns
Fittingly, the initial amphibians begin their quest for a partner around February 14th, but others travel as far as spring, waiting until it gets night and travelling after sunset. During that period, toads start moving from where they have been hibernating "all pretty much at the same time."
A local helper, who grew up in the region and has been trying to protect its amphibians since he was a child, explains that "They've got just one focus: to go and have an orgy." If their path happens to a street, they could all get run over, and that mating period would never happen – stopping a next generation of toads from being produced.
Toad Patrols Across the United Kingdom
Finding hundreds of dead toads on nearby streets "resonates deeply with people," and has led to the formation of toad patrols throughout the UK – hundreds of organizations are officially listed with a countrywide program. These groups collect toads and carry them across roads in containers, as well as counting the quantity of toads they find and lobbying for other protection measures, such as road closures and underground wildlife tunnels.
Volunteers tend to operate during the migration season, when amphibian movements are frequent. However, this means they can overlook numbers of young toads, which, having existed as spawn 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 adult toads are killed, their carcasses can be counted.
Year-Round Efforts
In contrast to many groups, one local team, who are in their eighth season of operating, go out year-round – not every night, but whenever weather are damp, or if a member has reported about a toad sighting in their group chat. When I ask to join them on duty, they admit it is "not ideal conditions" – winter dormancy has started and it's been a dry day – but a few of the helpers gamely agree to patrol their route with me and see what we can find. "If anyone can locate any toads tonight, those two will spot 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 barbed wire fence to inspect beneath some logs.
Family Participation
The family duo became part of the patrol a while back. The youngster loves all things nature-related and has an ambition to become a environmentalist, so his parent started to search for activities they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner explains – so when the group was seeking a new manager recently, she volunteered for the role.
The teenager, too, has played an important role in the organization. A video he created, urging the municipal authority to block a street through a nature reserve during migration season, swung the decision the team's way. After a twelve months of campaigning, the authority agreed to an "restricted access" rule between 5pm and 5am from February through to spring. The majority of motorists duly avoided the road.
Other Wildlife and Challenges
A few cars go past when I'm out on duty and we find some victims as a result – no toads, but several crushed salamanders. We spot one live amphibian as well, and the teenager is particularly pleased to see a daddy longlegs, which dances in his hands. Yet in spite of the team's hardest attempts to show me a toad, the local population has obviously gone dormant for the winter. It seems that I couldn't have found any more luck anywhere else in the country – all the patrol groups I reach out to explain that it's very difficult at this season.
They project rescuing nearly 10,000 grown amphibians during migration
A message I receive from a different helper, who has kindly made the effort to look for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, reaches me with the subject line: "No toads." However, in February and March, he tells me, the team plans to assist around 10,000 adult toads across the road.
Impact and Challenges
How much of a difference can these organizations actually make? "The reality that people are doing this regularly on chilly, wet and miserable late nights is quite extraordinary," notes an expert. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – partly since traffic is not the only threat.
Other Dangers
The climate crisis has meant longer periods of drought, which cause the wrong conditions for some of the animals that toads eat, such as invertebrates, while warmer ponds have led to an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also cause toads to wake up from their dormancy more often, interfering with the energy conservation vital to their existence. Habitat destruction – especially the disappearance of large ponds – is an additional threat.
Researchers are "always a bit worried about putting too much of a utilitarian spin on wildlife," however "There is a big value in just their presence." But toads do have an significant part in the ecosystem, consuming pretty much any small creatures or tiny organisms they can swallow and in turn feeding a number of predators, such as hedgehogs and otters. Improving conditions for toads – such as building water habitats, conserving woodland and installing amphibian passages – "benefits for a whole bunch of additional wildlife."
Historical Significance
Another reason to try to keep toads around is their "historical significance," notes an expert. Legends and tales around toads go back {centuries|hundred
