It's Friday night at 7:30, but instead of heading to the pub or relaxing at home, I've caught a train to a market town in the countryside to join volunteers from a amphibian rescue group. These committed people give up their evenings to safeguard the local toad population.

A Worrying Decline in Numbers

The Bufo bufo is becoming increasingly rare. A recent study conducted by an amphibian and reptile charity revealed that the British common toad numbers have almost halved since 1985. Seeing a species that has been a stalwart of the British countryside in decline is labeled "worrying" by researchers. Toads "don't require very specific conditions" and "ought to live quite well in the majority of areas in the UK," meaning if even they are struggling to persist, "it indicates that things are not as they should be."

The Danger from Roads

Though the study didn't examine the causes for the drop, cars is a major factor. Calculations suggest that 20 tonnes of toads are killed on British roads every year – that is, several hundred thousand. In contrast to frogs, which would probably be content to mate "if you left out a bucket of water," toads prefer big bodies of water. Their capacity to remain away from water for longer than frogs allows they can journey farther to reach them – sometimes hundreds of metres. They usually stick to their traditional paths – it's typical for mature amphibians to go back to their birth pond to mate.

Breeding Habits

Fittingly, the initial amphibians start their journey for a partner around Valentine's day, but some move as far as April, until it gets night and travelling through the night. During that time, toads begin migrating from where they have been overwintering "all pretty much at the same time."

One volunteer, who was raised in the area and has been trying to protect its toad population since he was a child, explains that "Their sole purpose: to go and mate." If their route crosses a road, they could be killed by traffic, and that breeding season would be lost – preventing a next generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding many of dead toads on local roads "inherently strikes a chord with people," and has resulted in the creation of toad patrols throughout the UK – hundreds of organizations are currently registered with a national initiative. These teams collect toads and transport them across roads in buckets, as well as recording the number of toads they find and advocating for other protection measures, such as blocked roads and amphibian passages.

Patrols usually work during the migration season, when toad crossings are more regular. However, this means they can overlook groups of young toads, which, having been spawn and then juveniles, leave their ponds over an irregular timetable in late summer. Because of their small stature – just a couple of cm wide – "they can get obliterated by vehicles." And as being hit "basically turns them into mush," it's harder to collect information on them. At least when mature amphibians are lost, their carcasses can be tallied.

Year-Round Work

In contrast to many groups, a specific volunteer group, who are in their eighth year of functioning, go out year-round – not nightly, but when weather are damp, or if someone has reported about a amphibian spotting in their messaging app. When I ask to join them on duty, they concede it is "not a toady night" – toad hibernation season has started and it's been a dry day – but several of the volunteers willingly accept to patrol their route with me and see what we can find. "Should 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 single toad sighting, and now they have climbed over a barbed wire fence to check under some wood.

Family Participation

The mother and son became part of the patrol a while back. The teenager loves all things nature-related and has an goal to become a conservationist, so his mother started to look for things they could do together to help local wildlife. Now she loves it as much as he does, the middle-aged entrepreneur tells me – so when the team was seeking a new manager recently, she volunteered for the role.

The teenager, too, has been instrumental in the organization. A clip he created, imploring the municipal authority to close a street through a protected area during migration season, influenced the outcome the group's way. After a twelve months of campaigning, the authority agreed to an "restricted access" restriction between evening and morning from late winter through to April. Most drivers respected and avoided the route.

Additional Species and Difficulties

Several vehicles go by when I'm out on duty and we discover some victims as a result – no toads, but three squashed newts. We spot one live amphibian as well, and the teenager is particularly pleased to see a harvestman, which dances in his hands. Yet despite the group's best efforts to let me see a toad, the native community has clearly gone dormant for the colder months. It seems that I wouldn't have had any better success anywhere else in the country – all the rescue teams I contact explain that it's near-impossible at this season.

A message I get from a different helper, who has generously taken the trouble to look for toads in a noted location, considered the biggest tracked toad population in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he informs me, the team plans to assist approximately ten thousand mature amphibians over the street.

Effectiveness and Challenges

How much of a difference can these organizations actually make? "The reality that volunteers are doing this regularly on chilly, wet and miserable evenings is quite extraordinary," notes an expert. "That's something that very much deserves recognition." However, while toad patrols are able to slow the decline, they can't stop it completely – not least because traffic is not the only threat.

Other Dangers

The global warming has meant extended spells of drought, which create the poor environment for some of the creatures that toads consume, such as invertebrates, while higher water temperatures have caused an increase of toxic plants, which can be toxic to toads. Milder winters also cause toads to wake up from their dormancy more often, disrupting the resource preservation crucial to their existence. Habitat destruction – particularly the loss of large ponds – is another menace.

Experts are "often concerned about overemphasizing practical benefits on biodiversity," however "It's important in just their presence." But toads play an important role in the food chain, eating pretty much any invertebrates or small animals they can swallow and in turn feeding a number of predators, such as wildlife. Enhancing situations for toads – such as building water habitats, protecting forests and installing toad tunnels – "we'll improve them for a wide range of additional wildlife."

Historical Significance

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