Can Britain's Toads Be Saved from Roads and Terrible Decline?
It is 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 dedicated individuals sacrifice their evenings to safeguard the local toad population.
An Alarming Drop in Numbers
The Bufo bufo is becoming increasingly rare. A recent research conducted by an amphibian and reptile charity revealed that the British common toad numbers have dropped by half since 1985. Seeing a creature that has been a fixture of the British countryside in decrease is described as "concerning" by researchers. Toads "don't require very particular environments" and "ought to live successfully in most of areas in the UK," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."
Toad populations across the UK have declined by almost 50% since the 1980s
The Danger from Traffic
Though the research didn't examine the reasons for the decline, cars is a major factor. Estimates indicate that 20 tonnes of toads are killed on British roads every year – that is, hundreds of thousands. Unlike frogs, which might be happy to mate "if you left out a bucket of water," toads favor big bodies of water. Their ability to stay out of water for more time than frogs means they can journey farther to reach them – sometimes long distances. They tend to stick to their ancestral migration routes – it's common for adult toads to go back to their birth pond to mate.
Breeding Patterns
Fittingly, the first toads start their journey for a mate around February 14th, but some move as far as April, until it gets dark and moving through the night. During that time, toads begin migrating from wherever they have been hibernating "all pretty much at the same time."
One volunteer, who was raised in the area and has been working to save its toad population since he was a child, notes that "Their sole purpose: to go and have an orgy." If their path crosses a road, they could be killed by traffic, and that breeding season would be lost – stopping a next generation of toads from being born.
Rescue Groups Throughout the UK
Finding many of dead toads on local roads "resonates deeply with people," and has led to the formation of rescue teams throughout the UK – 274 groups are officially listed with a countrywide program. These teams collect toads and transport them across roads in buckets, as well as recording the quantity of toads they find and lobbying for other safety solutions, such as road closures and amphibian passages.
Volunteers usually work during the migration season, when amphibian movements are frequent. However, this means they can overlook numbers of toadlets, which, having existed as spawn 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 run over "essentially crushes them," it's more difficult to collect information on them. At least when mature amphibians are lost, their carcasses can be tallied.
Annual Efforts
Unlike most patrols, one local team, who are in their eighth season of operating, go out throughout the year – not every night, but whenever weather are warm and wet, or if a member has posted about a toad sighting in their group chat. When I request to accompany them on patrol, they concede it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but a few of the helpers gamely agree to walk up and down their route with me and see what we can find. "If anyone can locate any toads tonight, that pair will find one," says the patrol manager, indicating her teenage child and the longtime volunteer. We've been out for 120 minutes without a single toad sighting, and now they have climbed over a wire barrier to check under some wood.
Community Involvement
The mother and son became part of the patrol a year and a half ago. The teenager loves all things nature-related and has an goal to become a environmentalist, so his parent started to look for things they could do together to protect native animals. Now she enjoys it as much as he does, the middle-aged small business owner explains – so when the team was seeking a new manager recently, she decided to step up.
The teenager, too, has played an important role in the organization. A clip he made, urging the local council to close a street through a protected area during breeding time, influenced the outcome the group's way. After a year of lobbying, the authority approved an "access-only" restriction between 5pm and 5am from February through to spring. Most drivers respected and avoided the road.
Additional Species and Challenges
A few vehicles go by when I'm out on patrol and we find some casualties as a consequence – no amphibians, but three squashed newts. We see one living newt as well, and the youngster is especially excited to see a harvestman, which dances in his palms. Yet in spite of the group's hardest attempts to let me see a toad, the native community has obviously gone dormant for the winter. It appears that I couldn't have found any more luck elsewhere in the nation – all the rescue teams I contact explain that it's near-impossible at this season.

One email I get from a different helper, who has generously taken the trouble to check for toads in a noted location, thought to be the largest accurately monitored toad population in the UK, reaches me with the title: "No toads." However, in February and March, he tells me, the group plans to assist approximately ten thousand mature amphibians across the road.
Impact and Limitations
How much of a difference can these organizations truly achieve? "The reality that volunteers are doing this consistently on cold, damp and unpleasant evenings is quite extraordinary," says an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since vehicles is just one danger.
Other Dangers
The global warming has meant extended spells of dry weather, which cause the wrong conditions for some of the animals that toads consume, such as invertebrates, while warmer ponds have caused an rise of blue-green algae, which can be toxic to toads. Milder winters also lead toads to emerge from their hibernation more often, interfering with the resource preservation vital to their life cycle. Habitat destruction – particularly the disappearance of big water bodies – is an additional threat.
Experts 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 important role in the food chain, eating pretty much any small creatures or tiny organisms they can swallow and in turn feeding a number 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 Importance
Another reason to work to preserve toads present is their "historical significance," adds an expert. Legends and tales around toads date back {centuries|hundred
