It's a Friday night at half past seven, but instead of 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 protect the native amphibian community.

A Worrying Decline in Population

The Bufo bufo is becoming increasingly uncommon. A recent study led by an amphibian and reptile charity showed that the UK toad population have almost halved since 1985. Seeing a creature that has been a stalwart of the UK landscape in decrease is described as "worrying" by researchers. Toads "don't need very specific conditions" and "should be able to live quite well in most of areas in the UK," meaning if even they are struggling to persist, "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 research didn't examine the reasons for the decline, traffic is a major factor. Estimates suggest that 20 tons of toads are crushed 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 large ponds. Their ability to stay out of water for longer than frogs allows they can travel further to find them – often hundreds of metres. They usually stick to their traditional paths – it's typical for mature amphibians to return to their birth pond to mate.

Migration Habits

Appropriately enough, the initial amphibians start their journey for a partner around February 14th, but others travel as far as April, waiting until it gets night and moving through the night. During that period, toads start moving from wherever they have been hibernating "almost simultaneously."

One volunteer, who was raised in the area and has been trying to protect its toad population since he was a boy, explains that "Their sole purpose: to go and mate." If their route crosses a street, they could be killed by traffic, 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 "resonates deeply with people," and has resulted in the creation of toad patrols across the UK – 274 groups are currently registered with a countrywide program. These groups pick up toads and transport them over streets in buckets, as well as counting the number of toads they find and advocating for other safety solutions, such as blocked roads and amphibian passages.

Volunteers usually work during the migration season, when amphibian movements are frequent. However, this means they can overlook groups of young toads, which, having existed as spawn and then tadpoles, leave their ponds over an unpredictable schedule 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 hit "essentially crushes them," it's more difficult to get data on them. At least when adult toads are lost, their carcasses can be counted.

Year-Round Efforts

Unlike many groups, one local team, who are in their eighth season of operating, go out throughout the year – not nightly, but whenever weather are warm and wet, 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 begun and it's been a dry day – but a few of the helpers gamely agree to walk up and down their area with me and see what we can find. "Should anyone can locate any toads tonight, those two will spot 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 barbed wire fence to inspect beneath some wood.

Community Participation

The mother and son joined the patrol a year and a half ago. The youngster adores 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 help local wildlife. Now she loves it as much as he does, the middle-aged small business owner explains – so when the team was seeking a fresh coordinator recently, she decided to step up.

The youth, too, has played an important role in the group. A video he made, imploring the municipal authority to block a road through a nature reserve during breeding time, influenced the outcome the team's way. After a twelve months of lobbying, the council agreed to an "access-only" restriction between 5pm and 5am from February through to spring. The majority of motorists respected and avoided the route.

Additional Species and Challenges

Several cars go by when I'm out on duty and we discover some victims as a consequence – no toads, but several crushed salamanders. We spot one live amphibian as well, and the teenager is especially excited to see a harvestman, which dances in his palms. Yet despite the group's best efforts to show me a toad, the native community has clearly settled down for the winter. It appears that I wouldn't have had any more luck anywhere else in the nation – all the rescue teams I reach out to explain that it's near-impossible at this time of year.

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

One email I get from a different helper, who has kindly taken the trouble to check for toads in a famous site, thought to be the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "No toads." However, in late winter, he tells me, the team plans to assist approximately 10,000 adult toads across the road.

Effectiveness and Challenges

How much of a difference can these organizations truly achieve? "The fact that volunteers are performing this consistently on chilly, wet and miserable late nights is remarkable," says an researcher. "This effort that very much deserves recognition." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because traffic is just one danger.

Additional Threats

The climate crisis has resulted in longer periods of dry weather, which cause the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while warmer ponds have led to an rise of blue-green algae, which can be toxic to toads. Milder winters also cause toads to emerge from their dormancy more often, disrupting the energy conservation crucial to their existence. Habitat destruction – especially the loss of large ponds – is an additional threat.

Experts are "always a bit worried about overemphasizing practical benefits on wildlife," but "It's important in just their presence." But toads do have an significant part in the food chain, eating pretty much any small creatures or small animals they can fit in their mouths and in turn feeding a variety of predators, such as hedgehogs and otters. Improving conditions for toads – ie creating more ponds, conserving woodland and constructing toad tunnels – "benefits for a wide range of other species."

Historical Significance

Another reason to try to keep toads present is their "historical significance," adds an specialist. Legends and tales around toads go back {centuries|hundred
