It is Friday evening at half past seven, but rather than heading to the pub or watching a film, I've caught a train to a town in Wiltshire to meet up with volunteers from a toad patrol. These dedicated individuals give up their nights to safeguard the native amphibian community.

A Worrying Drop in Population

The common toad is becoming increasingly uncommon. A latest study conducted by an wildlife conservation group showed that the British common toad numbers have dropped by half since 1985. Observing a creature that has been a stalwart of the UK landscape in decrease is labeled "worrying" by researchers. Toads "don't need very specific conditions" and "should be able to live quite well in the majority of habitats in the UK," so 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 Danger from Roads

Though the study didn't examine the causes for the decline, cars certainly plays a part. Calculations indicate that 20 tonnes of toads are crushed on British roads every year – in other words, several hundred thousand. Unlike frogs, which might be happy to mate "with just a bucket of water," toads favor big bodies of water. Their ability to stay out of water for more time than frogs means they can travel further to reach them – often long distances. They usually stick to 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 far as April, waiting until it gets night and travelling through the night. During that period, toads begin migrating from where they have been hibernating "all pretty much at the same time."

A local helper, who was raised in the region and has been trying to protect its amphibians since he was a child, explains that "Their sole purpose: to go and mate." If their route happens to a street, they could be killed by traffic, and that breeding season would never happen – stopping a new generation of toads from being produced.

Rescue Groups Throughout the UK

Finding many of dead toads on nearby streets "inherently strikes a chord with people," and has resulted in the creation of rescue teams throughout the UK – hundreds of organizations are officially listed with a national initiative. These teams pick up toads and carry them over streets in containers, as well as counting the quantity of toads they encounter and advocating for other protection measures, such as blocked roads and underground wildlife tunnels.

Patrols tend to operate during the migration season, when amphibian movements are frequent. However, this implies they can miss groups of young toads, which, having been eggs and then tadpoles, leave their water habitats over an irregular timetable in late summer. Because of their size – just a couple of cm wide – "they can get obliterated by vehicles." And as being run over "essentially crushes them," it's harder to collect information on them. At least when mature amphibians are lost, their remains can be counted.

Annual Efforts

In contrast to most patrols, a specific volunteer group, who are in their eighth year of functioning, go out throughout the year – not every night, but whenever conditions are warm and wet, or if someone has reported about a amphibian spotting in their messaging app. When I request to accompany them on patrol, they concede it is "not ideal conditions" – toad hibernation season has started and it's been a dry day – but several of the volunteers willingly accept to walk up and down their route with me and see what we can find. "Should anyone can locate any toads tonight, that pair will find one," says the patrol manager, indicating her teenage child and the longtime volunteer. After for two hours without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to inspect beneath some logs.

Community Participation

The mother and son joined the patrol a while back. The youngster adores all things nature-related and has an goal to become a environmentalist, so his parent started to search for things they could do together to protect local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner explains – so when the group was looking for a new manager recently, she decided to step up.

The youth, too, has been instrumental in the organization. A clip he made, imploring the local council to block a road through a protected area during breeding time, influenced the outcome the group's way. After a year of lobbying, the council approved an "restricted access" rule between 5pm and 5am from late winter through to spring. The majority of motorists respected and avoided the road.

Other Wildlife and Challenges

A few vehicles go by when I'm out on duty and we discover some casualties as a result – no amphibians, but several crushed salamanders. We spot one living newt as well, and the teenager is particularly pleased to see a daddy longlegs, which dances in his hands. Yet despite the group's best efforts to let me see a toad, the native community has obviously gone dormant for the colder months. It appears that I wouldn't have had any more luck elsewhere in the nation – all the rescue teams I reach out to explain that it's near-impossible at this season.

A message I get from another volunteer, who has kindly taken the trouble to check for toads in a famous site, considered the largest accurately monitored toad population in the UK, reaches me with the title: "None found." However, in late winter, he informs me, the group expects to help around ten thousand adult toads over the street.

Effectiveness and Limitations

How much of a difference can these groups actually make? "The fact that volunteers are doing this regularly on chilly, wet and miserable late nights is remarkable," says an expert. "That's something that very much deserves recognition." However, while rescue teams are able to slow the decline, they can't stop it completely – not least because vehicles is not the only threat.

Additional Threats

The global warming has meant longer periods of dry weather, which create the poor environment for some of the creatures that toads consume, such as worms and slugs, while warmer ponds have led to an increase of blue-green algae, which can be toxic to toads. Milder winters also cause toads to wake up from their hibernation more frequently, disrupting the energy conservation crucial to their life cycle. Loss of environment – particularly the disappearance of large ponds – is an additional threat.

Researchers are "always a bit worried about putting too much of a utilitarian spin on wildlife," however "There is a big value in just having these animals around." 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 sustaining a number of birds and mammals, such as wildlife. Enhancing situations for toads – such as building water habitats, protecting forests and constructing amphibian passages – "benefits for a wide range of other species."

Historical Importance

Another reason to try to keep toads present is their "historical significance," notes an expert. Myths and folklore around toads date back {centuries|hundred
