It is Friday night at half past seven, but rather than going out or watching a film, I've caught a train to a market town in Wiltshire to meet up with volunteers from a toad patrol. These committed people sacrifice their nights to safeguard the native amphibian community.

An Alarming Decline in Population

The common toad is becoming increasingly uncommon. A latest research led by an wildlife conservation group revealed that the UK toad population have dropped by half since the mid-1980s. Seeing a creature that has been a fixture of the British countryside in decline is described as "worrying" by experts. Toads "don't require very specific conditions" and "ought to live successfully in most of areas in Britain," so if even they are struggling to persist, "it indicates that things are not as they should be."

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

The Danger from Roads

Though the study didn't cover the causes for the decline, cars certainly plays a part. Calculations suggest that 20 tons of toads are killed on British roads every year – that is, several hundred thousand. Unlike frogs, which would probably be content to mate "if you left out a small container," toads prefer big bodies of water. Their capacity to stay out of water for longer than frogs allows they can travel further to find them – sometimes long distances. They tend to stick to their ancestral migration routes – it's typical for mature amphibians to return to their birth pond to mate.

Migration Patterns

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

A local helper, who was raised in the region and has been trying to protect its toad population since he was a boy, explains that "They've got just one focus: to go and mate." If their path happens to a street, they could be killed by traffic, and that breeding season would be lost – preventing a new generation of toads from being produced.

Toad Patrols Across the United Kingdom

Seeing hundreds of dead toads on nearby streets "resonates deeply with people," and has resulted in the creation of rescue teams throughout the UK – hundreds of organizations are officially listed with a countrywide program. These groups collect toads and carry them over streets in buckets, as well as counting the number of toads they find and advocating for other protection measures, such as road closures and underground wildlife tunnels.

Patrols tend to operate during the breeding period, when toad crossings are frequent. However, this implies they can overlook numbers of young toads, which, having been eggs and then tadpoles, exit their water habitats over an unpredictable schedule in late summer. Because of their small stature – just one or two centimetres 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 adult toads are killed, their carcasses can be counted.

Year-Round Efforts

Unlike many groups, a specific volunteer group, who are in their eighth year of operating, go out throughout the year – not every night, but when conditions are warm and wet, or if a member has posted about a toad sighting in their messaging app. When I ask to join them on patrol, they admit it is "not ideal conditions" – winter dormancy has begun and it's been a dry day – but several of the helpers gamely agree to walk up and down their area with me and see what we can find. "If anyone can locate any toads tonight, those two will find one," says the group coordinator, indicating her teenage child and the experienced member. After for two hours without a single toad sighting, and now they have scaled a barbed wire fence to inspect beneath some wood.

Family Participation

The mother and son joined the patrol a while back. The teenager loves all things wildlife and has an ambition to become a environmentalist, so his parent started to look for activities they could do together to protect native animals. Now she loves 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 youth, too, has played an important role in the group. A clip he created, urging the municipal authority to block a road through a nature reserve during migration season, swung the decision the team's way. After a twelve months of lobbying, the authority agreed to an "access-only" restriction between evening and morning from February through to April. 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 find some casualties as a result – no amphibians, but several crushed salamanders. We spot one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which dances in his palms. Yet in spite of the team's best efforts to show me a toad, the local population has obviously gone dormant for the winter. It appears that I wouldn't have had any more luck anywhere else in the nation – all the rescue teams I contact clarify that it's very difficult at this season.

A message I receive from a different helper, who has generously made the effort to look for toads in a noted location, thought to be the largest accurately monitored toad group in the UK, arrives in my inbox with the title: "None found." However, in late winter, he informs me, the team expects to help around ten thousand mature amphibians across the road.

Impact and Challenges

How much of a difference can these groups truly achieve? "The reality that people are performing this regularly on chilly, wet and miserable evenings is quite extraordinary," says an expert. "This effort that very much deserves recognition." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – partly since vehicles is just one danger.

Additional Threats

The global warming has meant longer periods of dry weather, which cause the poor environment for some of the animals that toads consume, such as invertebrates, while higher water temperatures have caused an increase of blue-green algae, which can be toxic to toads. Warmer cold seasons also cause toads to emerge from their dormancy more frequently, interfering with the resource preservation vital to their life cycle. 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 "There is a big value in just having these animals around." But toads do have an important role in the food chain, eating pretty much any small creatures or small animals they can swallow and in turn feeding a number of birds and mammals, such as wildlife. Improving conditions for toads – such as creating more ponds, conserving woodland and installing toad tunnels – "we'll improve them for a wide range of additional wildlife."

Cultural Importance

Another reason to work to preserve toads present is their "important cultural value," notes an specialist. Myths and folklore around toads go back {centuries|hundred
