It is a Friday evening at half past seven, but rather than going out or watching a film, I've taken a train to a market town in the countryside to meet up with local helpers from a amphibian rescue group. These dedicated individuals give up their evenings to protect the native amphibian community.

A Worrying Drop in Population

The Bufo bufo is becoming increasingly uncommon. A latest study led by an amphibian and reptile charity revealed that the UK toad population have dropped by half since the mid-1980s. Seeing a species that has been a stalwart of the British countryside in decrease is labeled "worrying" by experts. Toads "don't need very particular environments" and "should be able to live quite well in most of habitats in the UK," so if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

The Threat from Roads

Though the study didn't cover the causes for the drop, traffic certainly plays a part. Estimates suggest that 20 tons of toads are killed on UK roads annually – that is, hundreds of thousands. Unlike frogs, which would probably be happy to mate "if you left out a small container," toads favor large ponds. Their ability to remain away from water for longer than frogs means they can travel further to reach them – sometimes hundreds of metres. They tend to follow their ancestral migration routes – it's typical for adult toads to go back to their natal pond to mate.

Breeding Habits

Appropriately enough, the initial amphibians start their journey for a partner around Valentine's day, but others travel as far as spring, until it gets dark and moving after sunset. During that time, toads start moving from wherever they have been overwintering "almost simultaneously."

A local helper, who was raised in the area and has been working to save its toad population since he was a child, notes that "They've got just one focus: to go and have an orgy." If their route happens to a street, they could all get run over, and that breeding season would be lost – preventing a next generation of toads from being produced.

Rescue Groups Throughout the UK

Seeing many of toad carcasses on local roads "inherently strikes a chord with people," and has resulted in the creation of toad patrols throughout the UK – 274 groups are officially listed with a national initiative. These teams pick up toads and carry them over streets in containers, as well as recording the number of toads they encounter and lobbying for other safety solutions, such as road closures and amphibian passages.

Volunteers usually work during the migration season, when amphibian movements are frequent. However, this means they can overlook numbers of young toads, which, having been eggs and then tadpoles, leave their ponds over an irregular timetable in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "essentially crushes them," it's more difficult to collect information on them. At least when mature amphibians are lost, their remains can be tallied.

Annual Efforts

In contrast to most patrols, one local team, who are in their eighth year of functioning, go out year-round – not nightly, but when conditions are damp, or if someone has posted about a amphibian spotting in their group chat. 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 several of the helpers gamely agree to walk up and down their route with me and see what we can find. "If anyone can find any toads tonight, those two will spot one," says the group coordinator, indicating her teenage child and the experienced member. After for two hours without a glimpse of any amphibians, and now they have climbed over a barbed wire fence to inspect beneath some wood.

Community Involvement

The mother and son joined the group a year and a half ago. The youngster adores all things nature-related and has an ambition 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 explains – so when the team was seeking a fresh coordinator recently, she decided to step up.

The youth, too, has been instrumental in the group. A clip he made, imploring the municipal authority to close a road through a nature reserve during migration season, influenced the outcome the team's way. After a twelve months of lobbying, the authority approved an "restricted access" rule between evening and morning from late winter through to April. The majority of motorists duly avoided the route.

Additional Species and Challenges

A few cars go past when I'm out on patrol and we find some casualties as a consequence – no amphibians, but three squashed newts. We see one living newt as well, and the teenager is especially excited to see a harvestman, which dances in his hands. Yet despite the group's hardest attempts to let me see a toad, the native community has obviously gone dormant for the colder months. It seems that I wouldn't have had any better success elsewhere in the nation – all the patrol groups I reach out to clarify that it's near-impossible at this season.

A message I receive from a different helper, who has generously made the effort to check 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: "No toads." However, in February and March, he tells me, the group expects to help approximately ten thousand adult toads over the street.

Effectiveness and Limitations

How much of a difference can these groups truly achieve? "The fact that volunteers are doing this regularly on cold, damp and unpleasant late nights is remarkable," notes an researcher. "This effort that very much should be celebrated." However, while toad patrols are able to reduce the drop, they cannot prevent it entirely – not least because vehicles is just one danger.

Additional Threats

The global warming has resulted in extended spells of drought, which create the poor environment for some of the animals that toads consume, such as worms and slugs, while warmer ponds have caused an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also lead toads to wake up from their dormancy more frequently, interfering with the energy conservation crucial to their existence. Loss of environment – particularly the disappearance of big water bodies – is another menace.

Researchers are "always a bit worried about overemphasizing practical benefits on biodiversity," but "There is a big value in just their presence." But toads do have an significant part in the food chain, consuming almost any small creatures or small animals they can fit in their mouths and in turn feeding a variety of birds and mammals, such as hedgehogs and otters. Enhancing conditions for toads – ie creating more ponds, protecting forests and installing toad tunnels – "benefits for a whole bunch of other species."

Historical Importance

Another reason to work to preserve toads around is their "historical significance," adds an specialist. Myths and folklore around toads go back {centuries|hundred
