Can Britain's Common Toads Be Saved from Roads and Terrible Decline?
It is a Friday evening at 7:30, but rather than going out or watching a film, I've taken a train to a town in the countryside to join volunteers from a amphibian rescue group. These committed people sacrifice their evenings to protect the local toad population.
An Alarming Drop in Numbers
The common toad is becoming increasingly rare. A latest study conducted by an wildlife conservation group showed that the British common toad numbers have dropped by half since 1985. Observing a creature that has been a stalwart of the British countryside in decline is labeled "concerning" by researchers. Toads "don't need very specific conditions" and "ought to live quite well in most of areas in Britain," meaning if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."
Toad populations across the UK have declined by almost 50% since the 1980s
The Threat from Traffic
Though the study didn't cover the causes for the drop, cars is a major factor. Calculations indicate that 20 tons of toads are killed on British roads annually – that is, hundreds of thousands. In contrast to frogs, which would probably be content to mate "if you left out a small container," toads favor big bodies of water. Their capacity to stay out of water for more time than frogs means they can journey farther to find them – sometimes long distances. They usually follow their traditional paths – it's typical for mature amphibians to return to their birth pond to mate.
Breeding Habits
Fittingly, the initial amphibians begin their quest for a mate around February 14th, but some move as late as April, waiting until it gets dark and moving after sunset. During that time, toads start moving from wherever they have been hibernating "all pretty much at the same time."
One volunteer, who grew up in the area and has been trying to protect its toad population since he was a child, notes that "They've got just one focus: to go and have an orgy." If their route happens to a road, they could be killed by traffic, and that mating period would never happen – stopping a new generation of toads from being produced.
Rescue Groups Throughout the UK
Finding many of toad carcasses on nearby streets "resonates deeply with people," and has led to the formation of rescue teams throughout the UK – 274 groups are currently registered with a national initiative. These groups collect toads and transport them over streets in buckets, as well as recording the number of toads they encounter and lobbying for other protection measures, such as road closures and amphibian passages.
Patrols usually work during the migration season, when amphibian movements are frequent. However, this means they can miss groups of young toads, which, having been eggs and then tadpoles, exit their water habitats over an unpredictable schedule in the end of summer. Because of their small stature – just a couple of cm 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 adult toads are lost, their remains can be tallied.
Annual Work
In contrast to most patrols, a specific volunteer group, who are in their eighth year of functioning, go out throughout the year – not every night, but when conditions are damp, or if a member has posted about a amphibian spotting in their messaging app. When I ask to join them on patrol, they concede it is "not a toady night" – toad hibernation season has started and it's been a dry day – but several of the helpers gamely agree to patrol their route with me and search for any toads. "If anyone can find any toads tonight, that pair will find one," says the group coordinator, pointing to her 14-year-old son and the experienced member. After for two hours without a single toad sighting, and now they have climbed over a wire barrier to inspect beneath some wood.
Community Participation
The mother and son joined the patrol a while back. The teenager adores all things wildlife and has an ambition to become a conservationist, so his mother started to look for things they could do jointly to protect native animals. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the group was seeking a new manager recently, she decided to step up.
The teenager, too, has been instrumental in the organization. A video he made, urging the local council to block a street through a protected area during breeding time, swung the decision the team's way. After a year of campaigning, the authority agreed to an "access-only" restriction between 5pm and 5am from late winter through to spring. Most drivers respected and avoided the route.
Other Wildlife and Difficulties
Several cars go past when I'm out on duty and we find 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 palms. Yet despite the team's hardest attempts to let me see a toad, the local population has obviously gone dormant for the winter. It seems that I wouldn't have had any better success anywhere else in the nation – all the rescue teams I contact explain that it's near-impossible at this season.
The group expects to help approximately 10,000 adult toads across the road
One email I receive from a different helper, who has kindly made the effort to look 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 plans to assist approximately ten thousand mature amphibians over the street.
Effectiveness and Challenges
How much of a difference can these groups actually make? "The reality that people are performing this regularly on cold, damp and unpleasant late nights is remarkable," says an expert. "This effort that very much should be celebrated." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – partly since vehicles is just one danger.
Other Dangers
The climate crisis has meant longer periods of dry weather, which cause the poor environment for some of the animals that toads consume, such as worms and slugs, while warmer ponds have caused an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also cause toads to wake up from their hibernation more often, interfering with the energy conservation crucial to their existence. Habitat destruction – especially the loss of large ponds – 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 do have an significant part in the food chain, eating almost any invertebrates or small animals they can fit in their mouths and in turn feeding a variety of predators, such as hedgehogs and otters. Enhancing situations for toads – such as creating more ponds, conserving woodland and installing toad tunnels – "we'll improve them for a wide range of other species."
Historical Significance
An additional motive to work to preserve toads around is their "important cultural value," notes an specialist. Myths and folklore around toads date back {centuries|hundred
