It's a Friday night at half past seven, but rather than going out or watching a film, I've taken a train to a market town in Wiltshire to join volunteers from a toad patrol. These committed people give up their evenings to protect the native amphibian community.
The common toad is becoming increasingly uncommon. A recent research conducted by an amphibian and reptile charity revealed that the UK toad population have dropped by half since 1985. Observing a species that has been a fixture of the UK landscape in decrease is labeled "concerning" by researchers. Toads "don't require very particular environments" and "ought to live quite well in most of areas in Britain," meaning if even they are struggling to persist, "it indicates that things are not as they should be."
The UK toad population has almost halved since 1985
Though the research didn't cover the causes for the drop, cars is a major factor. Estimates indicate that 20 tonnes of toads are killed on UK roads annually – that is, hundreds of thousands. Unlike frogs, which might be happy to mate "with just a small container," toads prefer big bodies of water. Their ability to stay out of water for more time than frogs allows they can travel further to reach them – often long distances. They usually follow their ancestral migration routes – it's typical for adult toads to return to their natal pond to mate.
Fittingly, the initial amphibians start their journey for a partner around Valentine's day, but some move as late as April, waiting until it gets dark and moving after sunset. During that period, toads begin migrating from where they have been hibernating "almost simultaneously."
A local helper, who grew up in the area and has been working to save its amphibians since he was a boy, explains that "They've got just one focus: to go and mate." If their path happens to a street, they could all get run over, and that breeding season would be lost – preventing a next generation of toads from being produced.
Finding many of toad carcasses on nearby streets "resonates deeply with people," and has led to the formation of rescue teams across the UK – 274 groups are currently registered with a national initiative. These teams collect toads and carry them over streets in containers, as well as recording the quantity of toads they find and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.
Patrols tend to operate during the breeding period, when toad crossings are more regular. However, this means they can overlook groups of toadlets, which, having been eggs and then juveniles, exit their ponds over an irregular timetable in the end of summer. Because of their small stature – 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 get data on them. At least when mature amphibians are killed, their remains can be counted.
Unlike most patrols, one local team, who are in their eighth year of operating, go out year-round – not every night, but when weather are damp, or if a member has reported about a amphibian spotting in their group chat. When I request to accompany them on duty, they concede it is "not a toady night" – toad hibernation season has begun and it's been a arid period – but a few of the volunteers willingly accept to walk up and down their route with me and search for any toads. "If anyone can locate any toads tonight, those two will spot one," says the patrol manager, indicating her teenage child and the experienced member. After for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to inspect beneath some wood.
The family duo joined the group a while back. The teenager loves all things nature-related and has an ambition to become a conservationist, so his mother started to look for activities they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the 41-year-old small business owner tells me – 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 group. A clip he created, urging the local council to close a road through a nature reserve during breeding time, swung the decision the team's way. After a year of campaigning, the council approved an "access-only" restriction between 5pm and 5am from February through to April. The majority of motorists duly avoided the road.
A few vehicles go past when I'm out on duty and we discover some casualties as a consequence – no toads, but three squashed newts. We spot one live amphibian as well, and the youngster is especially excited to see a daddy longlegs, which dances in his hands. Yet despite the team's hardest attempts to let me see a toad, the local population has obviously gone dormant for the winter. It appears that I couldn't have found any better success elsewhere in the country – all the patrol groups I reach out to clarify that it's near-impossible at this time of year.
This team anticipates assisting around ten thousand mature toads over the street
A message I receive from another volunteer, who has kindly taken the trouble to check for toads in a noted location, considered the biggest tracked toad group in the UK, reaches me with the title: "None found." However, in late winter, he tells me, the team plans to assist around ten thousand mature amphibians across the road.
How much of a difference can these groups truly achieve? "The reality that volunteers are performing this consistently on cold, damp and unpleasant evenings is remarkable," notes an expert. "That's something 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 not the only threat.
The global warming has resulted in longer periods of drought, which cause the poor environment for some of the creatures that toads consume, such as invertebrates, while higher water temperatures 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, disrupting the energy conservation vital to their existence. 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 biodiversity," however "There is a big value in just their presence." But toads play an significant part in the ecosystem, eating almost any small creatures or tiny organisms they can swallow and in turn sustaining a variety of predators, such as wildlife. Improving situations for toads – ie building water habitats, protecting forests and installing amphibian passages – "we'll improve them for a whole bunch of other species."
Another reason to work to preserve toads present is their "historical significance," notes an specialist. Legends and tales around toads go back {centuries|hundred
