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

A Worrying Drop in Numbers

The common toad is growing more rare. A recent research led by an amphibian and reptile charity showed that the UK toad population have dropped by half 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 need very particular environments" and "should be able to live quite well in the majority of areas in Britain," meaning if even they are not managing to survive, "it indicates that the ecosystem is unbalanced."

Since 1985, Britain's toad numbers have nearly been cut in half

The Threat from Traffic

Though the study didn't cover the causes for the decline, traffic certainly plays a part. Estimates suggest that 20 tons of toads are crushed on UK roads annually – in other words, several hundred thousand. Unlike frogs, which might be content 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 find them – sometimes hundreds of metres. They tend to stick to their traditional paths – it's typical for mature amphibians to return to their natal pond to mate.

Migration Habits

Fittingly, the initial amphibians begin their quest for a partner around February 14th, but some move as late as spring, waiting until it gets night and moving through the night. During that time, toads begin migrating from wherever they have been overwintering "all pretty much at the same time."

A local helper, who was raised in the area and has been working to save its amphibians since he was a boy, explains that "They've got just one focus: to go and mate." If their path happens to a road, they could all get run over, and that breeding season would never happen – stopping a next generation of toads from being produced.

Rescue Groups Across the UK

Finding hundreds of dead toads on local roads "inherently strikes a chord with people," and has resulted in the creation of toad patrols across the UK – 274 groups are currently registered with a national initiative. These teams collect toads and carry them over streets in containers, as well as recording the number of toads they find and lobbying for other safety solutions, such as road closures and underground wildlife tunnels.

Volunteers tend to operate during the migration season, when amphibian movements are frequent. However, this means they can overlook numbers of toadlets, which, having been eggs and then tadpoles, exit their ponds over an irregular timetable 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 "essentially crushes them," it's harder to collect information on them. At least when mature amphibians are killed, their remains can be tallied.

Annual Work

Unlike many groups, one local team, who are in their eighth year of operating, go out throughout the year – not every night, but when conditions are damp, or if a member has reported about a toad sighting in their messaging app. 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 arid period – but a few of the helpers gamely agree to patrol their route with me and see what we can find. "If anyone can locate any toads tonight, those two will spot one," says the patrol manager, pointing to her teenage child and the longtime volunteer. After for two hours without a single toad sighting, and now they have climbed over a wire barrier to check under some logs.

Community Involvement

The mother and son became part of the group a year and a half ago. The youngster adores all things nature-related and has an goal to become a environmentalist, so his mother started to look for things they could do jointly to protect native animals. Now she enjoys it as much as he does, the middle-aged entrepreneur tells me – so when the team was seeking a fresh coordinator lately, she volunteered for the role.

The teenager, too, has been instrumental in the group. A video he made, urging 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 council approved an "access-only" restriction between 5pm and 5am from February through to April. Most drivers duly avoided the route.

Additional Species and Challenges

Several vehicles go past when I'm out on patrol and we discover some casualties as a consequence – no toads, but several crushed salamanders. We spot one live amphibian as well, and the youngster is especially excited to see a daddy longlegs, which dances in his hands. Yet despite the group's best efforts to show me a toad, the native community has obviously settled down for the colder months. It appears that I wouldn't have had any more luck anywhere else in the country – all the patrol groups I reach out to clarify that it's near-impossible at this season.

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

One email I get from another volunteer, who has kindly made the effort to check for toads in a famous site, considered the biggest tracked toad population in the UK, reaches me with the title: "No toads." However, in late winter, he tells me, the group plans to assist approximately 10,000 mature amphibians over the street.

Effectiveness and Limitations

How much of a difference can these organizations truly achieve? "The reality that people are performing this regularly on chilly, wet and miserable late nights is quite extraordinary," says an expert. "That's something that very much should be celebrated." However, while toad patrols are able to reduce the drop, they can't stop it completely – partly since traffic is just one danger.

Additional Threats

The global warming has resulted in longer periods of dry weather, which cause the wrong conditions for some of the creatures that toads consume, such as invertebrates, while warmer ponds have caused an increase of toxic plants, which can be harmful to toads. Warmer cold seasons also cause toads to emerge from their hibernation more often, interfering with the resource preservation crucial to their existence. Loss of environment – particularly the disappearance of big water bodies – is another menace.

Experts are "always a bit worried 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, eating pretty much any invertebrates or small animals they can swallow and in turn feeding a variety of birds and mammals, such as wildlife. Improving conditions for toads – ie building water habitats, protecting forests and installing amphibian passages – "we'll improve them for a wide range of additional wildlife."

Cultural Significance

An additional motive to work to preserve toads present is their "historical significance," adds an specialist. Legends and tales around toads go back {centuries|hundred
