It's Friday night at 7:30, but rather than heading to the pub or watching a film, I've caught a train to a 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.

A Worrying Drop in Numbers

The common toad is becoming increasingly rare. A recent research conducted by an amphibian and reptile charity showed that the British common toad numbers have dropped by half since the mid-1980s. Seeing a species that has been a stalwart of the UK landscape in decrease is described as "concerning" by researchers. Toads "don't require very specific conditions" and "should be able to live successfully in most of areas in the UK," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."

Toad populations across the UK have declined by almost 50% since the 1980s

The Threat from Roads

Though the research didn't cover the causes for the drop, traffic is a major factor. Calculations indicate that 20 tonnes of toads are crushed on UK roads every year – that is, several hundred thousand. Unlike frogs, which would probably be happy to mate "if you left out a small container," toads prefer big bodies of water. Their ability to stay out of water for longer than frogs means they can journey farther to find them – sometimes hundreds of metres. They usually stick to their traditional paths – it's typical for mature amphibians to go back to their natal pond to mate.

Migration Patterns

Fittingly, the first toads start their journey for a mate around February 14th, but some move as far as spring, until it gets night and moving after sunset. During that period, toads begin migrating from wherever they have been hibernating "almost simultaneously."

One volunteer, who grew up in the area and has been working to save its amphibians since he was a child, notes that "Their sole purpose: to go and have an orgy." If their path happens to a road, they could all get run over, and that breeding season would be lost – stopping a new generation of toads from being born.

Rescue Groups Across the United Kingdom

Finding hundreds of dead toads on nearby streets "inherently strikes a chord with people," and has led to the formation of toad patrols across the UK – 274 groups are officially listed with a countrywide program. These groups pick up toads and carry them over streets in buckets, as well as recording the quantity of toads they encounter and lobbying for other safety solutions, such as blocked roads and amphibian passages.

Patrols tend to operate during the breeding period, when toad crossings are more regular. However, this means they can overlook numbers of young toads, which, having existed as spawn and then juveniles, leave their ponds over an unpredictable schedule in late summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." 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.

Annual Work

Unlike many groups, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not nightly, but when weather are damp, or if someone has posted about a toad sighting in their group chat. When I request to accompany them on patrol, they admit it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but several of the helpers willingly accept to walk up and down their area with me and see what we can find. "If anyone can find any toads tonight, those two will find one," says the patrol manager, pointing to her 14-year-old son and the experienced member. After for two hours without a glimpse of any amphibians, and now they have climbed over a wire barrier to check under some logs.

Family Participation

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

The youth, too, has been instrumental in the group. A clip he made, imploring the municipal authority to block a road through a protected area during migration season, swung the decision the group's way. After a year of campaigning, the authority approved an "restricted access" rule between 5pm and 5am from February through to April. Most drivers duly avoided the road.

Additional Species and Challenges

Several cars go past when I'm out on duty and we find some victims as a consequence – no toads, but several crushed salamanders. We see one live amphibian as well, and the youngster is particularly pleased to see a harvestman, which moves in his hands. Yet in spite of the group's hardest attempts to let me see a toad, the local population has clearly gone dormant for the colder months. It appears that I wouldn't have had any more luck anywhere else in the nation – 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

A message I get from a different helper, who has generously made the effort to look for toads in a famous site, thought to be the biggest tracked toad group 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 around 10,000 mature amphibians over the street.

Impact and Challenges

How much of a difference can these organizations truly achieve? "The fact that volunteers are doing this regularly on chilly, wet and miserable evenings is remarkable," notes an expert. "That's something that very much deserves recognition." However, while rescue teams are able to reduce the drop, they cannot prevent it entirely – not least because traffic is just one danger.

Other Dangers

The global warming has resulted in extended spells of dry weather, which cause the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have caused an increase of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to wake up from their hibernation more frequently, disrupting the resource preservation crucial to their existence. Habitat destruction – especially the disappearance of large ponds – is an additional threat.

Researchers are "often concerned 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 food chain, eating pretty much any small creatures or tiny organisms they can swallow and in turn feeding a variety of predators, such as hedgehogs and otters. Enhancing conditions for toads – such as building water habitats, protecting forests and constructing 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," adds an specialist. Legends and tales around toads date back {centuries|hundred
