It is Friday night at 7:30, but rather than going out or relaxing at home, I've taken a train to a market town in Wiltshire to join volunteers from a amphibian rescue group. These dedicated individuals give up their evenings to safeguard the local toad population.

A Worrying Drop in Numbers

The common toad is growing more uncommon. A latest study conducted by an amphibian and reptile charity revealed that the UK toad population have almost halved since 1985. Observing a species that has been a stalwart of the UK landscape in decrease is described as "worrying" by researchers. Toads "don't require very particular environments" and "should be able to live successfully in most of areas in the UK," so if even they are struggling to persist, "it indicates that the ecosystem is unbalanced."

The Danger from Roads

Though the research didn't examine the causes for the drop, traffic certainly plays a part. Estimates indicate that 20 tonnes of toads are killed on UK roads every year – that is, hundreds of thousands. In contrast to frogs, which might be happy to mate "with just a bucket of water," toads favor large ponds. Their capacity to remain away from water for longer than frogs means they can journey farther to reach them – sometimes hundreds of metres. They usually follow their ancestral migration routes – it's typical for adult toads to go back to their natal pond to mate.

Migration Patterns

Appropriately enough, the first toads start their journey for a mate around February 14th, but others travel as late as April, waiting 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 trying to protect its amphibians 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 all get run over, and that breeding season would be lost – preventing a new generation of toads from being born.

Rescue Groups Across the UK

Finding many of dead toads on nearby streets "inherently strikes a chord with people," and has led to the formation of rescue teams throughout the UK – hundreds of organizations are officially listed with a countrywide program. These groups pick up toads and transport 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 usually work during the migration season, when toad crossings are more regular. However, this implies they can miss numbers of toadlets, which, having existed as eggs and then tadpoles, leave 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 vehicles." And as being run over "basically turns them into mush," it's more difficult to collect information on them. At least when adult toads are lost, their remains can be counted.

Annual Efforts

In contrast to most patrols, one local team, who are in their eighth season of operating, go out throughout the year – not every night, but when conditions are damp, or if someone has reported about a toad sighting in their messaging app. When I ask to join them on patrol, they admit it is "not a toady night" – winter dormancy has started and it's been a arid period – but a few of the volunteers gamely agree to patrol their area with me and search for any toads. "If anyone can locate any toads tonight, that pair will find one," says the group coordinator, pointing to her teenage child and the experienced member. We've been out for 120 minutes without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to inspect beneath some logs.

Family Involvement

The mother and son joined the patrol a while back. The teenager loves all things wildlife and has an goal to become a environmentalist, so his mother started to search for activities they could do together 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 volunteered for the role.

The youth, too, has played an important role in the organization. A video he created, urging the municipal authority to block a road through a protected area during breeding time, swung the decision the team's way. After a twelve months of lobbying, the council approved an "access-only" rule between 5pm and 5am from February through to April. The majority of motorists respected and avoided the road.

Other Wildlife and Challenges

Several cars go past when I'm out on duty and we find some casualties as a consequence – no amphibians, but several crushed salamanders. We spot one living newt as well, and the youngster is particularly pleased to see a daddy longlegs, which moves in his palms. Yet despite the group's best efforts to show me a toad, the local population has obviously settled down for the winter. It appears that I couldn't have found any more luck elsewhere in the nation – all the patrol groups I contact explain that it's very difficult at this time of year.

One email I get from another volunteer, who has generously taken the trouble to look for toads in a famous site, thought to be the largest accurately monitored toad group in the UK, reaches me with the subject line: "No toads." However, in late winter, he tells me, the group plans to assist around ten thousand mature amphibians over the street.

Impact and Limitations

How much of a difference can these organizations truly achieve? "The reality that volunteers are performing this regularly on cold, damp and unpleasant late nights is quite extraordinary," notes an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – not least because vehicles is just one danger.

Additional Threats

The climate crisis has meant longer periods of drought, which cause the poor environment for some of the creatures that toads eat, such as invertebrates, while higher water temperatures have led to an rise of toxic plants, which can be toxic to toads. Milder winters also lead toads to wake up from their dormancy more frequently, disrupting the energy conservation crucial to their existence. Loss of environment – especially the loss of big water bodies – is another menace.

Experts are "often concerned about overemphasizing practical benefits on wildlife," but "It's important in just having these animals around." But toads play an important role in the food chain, consuming almost any invertebrates or tiny organisms they can swallow and in turn feeding a variety of birds and mammals, such as wildlife. Enhancing situations for toads – such as creating more ponds, conserving woodland and installing amphibian passages – "we'll improve them for a wide range of other species."

Cultural Significance

Another reason to try to keep toads present is their "important cultural value," notes an specialist. Legends and tales around toads go back {centuries|hundred
