It's a Friday evening at half past seven, but instead of heading to the pub or watching a film, I've caught a train to a market town in Wiltshire to join local helpers from a amphibian rescue group. These committed people give up their nights to safeguard the native amphibian community.

An Alarming Decline in Numbers

The Bufo bufo is becoming increasingly rare. A recent study conducted by an wildlife conservation group showed that the British common toad numbers have dropped by half since 1985. Seeing a species that has been a fixture of the British countryside in decline is labeled "concerning" by researchers. Toads "don't require very particular environments" and "ought to live quite well in most of habitats in Britain," so if even they are struggling to persist, "it kind of suggests that things are not as they should be."

The UK toad population has almost halved since 1985

The Danger from Roads

Though the study didn't examine the causes for the decline, cars certainly plays a part. Calculations indicate that 20 tonnes of toads are killed on UK roads annually – in other words, hundreds of thousands. Unlike frogs, which might be happy to mate "with just a bucket of water," toads prefer big bodies of water. Their capacity to remain away from water for more time than frogs means they can journey farther to find them – often hundreds of metres. They usually follow their ancestral migration routes – it's common for mature amphibians to return to their birth pond to mate.

Migration Patterns

Appropriately enough, the first toads begin their quest for a partner around Valentine's day, but others travel as late as April, until it gets dark and moving after sunset. During that period, toads begin migrating from wherever 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 boy, notes that "They've got just one focus: to go and mate." If their route happens to a road, they could be killed by traffic, and that breeding season would never happen – preventing a next generation of toads from being born.

Rescue Groups Throughout the UK

Finding many of toad carcasses on local roads "resonates deeply with people," and has resulted in the creation of toad patrols throughout the UK – 274 groups are officially listed with a countrywide program. These teams collect toads and carry them across roads in containers, as well as counting the number of toads they encounter and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Patrols usually work during the breeding period, when toad crossings are more regular. However, this means they can overlook numbers of toadlets, which, having been eggs and then juveniles, leave their ponds over an unpredictable schedule in the end of summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by vehicles." And as being hit "basically turns them into mush," it's more difficult to get data on them. At least when mature amphibians are killed, their carcasses can be counted.

Year-Round Work

In contrast to many groups, a specific volunteer group, who are in their eighth year of operating, go out year-round – not every night, but whenever conditions are warm and wet, or if a member has reported about a amphibian spotting in their group chat. When I ask to join them on duty, they concede it is "not a toady night" – winter dormancy has started and it's been a dry day – but several of the volunteers gamely agree to walk up and down their area with me and search for any toads. "If anyone can find any toads tonight, those two will spot one," says the patrol manager, pointing to her teenage child and the experienced member. We've been out for two hours without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some logs.

Family Participation

The mother and son became part of the group 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 local wildlife. Now she loves it as much as he does, the middle-aged entrepreneur explains – so when the team was seeking a fresh coordinator lately, she decided to step up.

The youth, too, has been instrumental in the organization. A video he created, urging the municipal authority to block a street through a protected area during breeding time, swung the decision the team's way. After a twelve months of campaigning, the authority agreed to an "access-only" rule between 5pm and 5am from February through to spring. Most drivers respected and avoided the route.

Additional Species and Challenges

A few cars go by when I'm out on patrol and we discover some casualties as a result – no amphibians, but several crushed salamanders. We see one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which moves in his palms. Yet despite the team's best efforts to let me see a toad, the native community has obviously gone dormant for the winter. It seems that I couldn't have found any better success elsewhere in the country – all the patrol groups I reach out to explain that it's very difficult at this season.

The group expects to help approximately 10,000 adult toads across the road

One email I get from a different helper, who has generously made the effort to check for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, reaches me with the title: "None found." However, in February and March, he tells me, the team expects to help approximately 10,000 mature amphibians across the road.

Effectiveness and Limitations

What level of impact can these organizations truly achieve? "The fact that people are performing this consistently on cold, damp and unpleasant late nights is quite extraordinary," says an expert. "That's something 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 vehicles is just one danger.

Additional Threats

The global warming has meant extended spells of drought, which cause the poor environment for some of the animals that toads eat, such as worms and slugs, while warmer ponds 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 energy conservation vital to their life cycle. Loss of environment – especially the loss of big water bodies – is an additional threat.

Researchers are "often concerned about overemphasizing practical benefits on wildlife," however "There is a big value in just their presence." But toads do have an significant part in the food chain, consuming pretty much any small creatures or small animals they can swallow and in turn sustaining a number of predators, such as hedgehogs and otters. Enhancing situations for toads – such as creating more ponds, protecting forests and constructing toad tunnels – "benefits for a whole bunch of other species."

Historical Significance

An additional motive to work to preserve toads present is their "important cultural value," notes an expert. Myths and folklore around toads go back {centuries|hundred
