It is a Friday night at half past seven, but instead of going out or watching a film, I've taken a train to a market town in the countryside to meet up with volunteers from a amphibian rescue group. These dedicated individuals sacrifice their nights to protect the local toad population.

A Worrying Drop in Numbers

The Bufo bufo is growing more rare. A latest research conducted by an wildlife conservation group showed that the British common toad numbers have dropped by half since 1985. Seeing a creature that has been a stalwart of the British countryside in decline is described as "worrying" by researchers. Toads "don't require very particular environments" and "ought to live quite well in most of habitats in the UK," meaning if even they are struggling to persist, "it kind of suggests that things are not as they should be."

The UK toad population has almost halved since 1985

The Threat from Roads

Though the study didn't cover the reasons for the drop, traffic certainly plays a part. Calculations suggest that 20 tonnes of toads are crushed on UK roads every year – in other words, several hundred thousand. Unlike frogs, which would probably be happy to mate "if you left out a small container," toads prefer large ponds. Their capacity to stay out of water for more time than frogs means they can journey farther to reach them – sometimes long distances. They tend to stick to their traditional paths – it's typical for mature amphibians to return to their birth pond to mate.

Breeding Habits

Appropriately enough, the initial amphibians start their journey for a partner around Valentine's day, but some move as far as spring, waiting until it gets night and moving through the night. During that period, toads start moving from where they have been hibernating "almost simultaneously."

One volunteer, who was raised in the region and has been trying to protect its toad population since he was a boy, notes that "They've got just one focus: to go and mate." If their path crosses a road, they could be killed by traffic, and that mating period would be lost – stopping a next generation of toads from being produced.

Rescue Groups Across the United Kingdom

Finding hundreds of dead toads on local roads "inherently strikes a chord with people," and has resulted in the formation of toad patrols throughout the UK – 274 groups are officially listed with a countrywide program. These teams pick up toads and transport them across roads in containers, as well as recording the quantity of toads they find and advocating for other safety solutions, such as blocked roads and underground wildlife tunnels.

Volunteers tend to operate during the breeding period, when toad crossings are more regular. However, this means they can overlook numbers of toadlets, which, having existed as spawn and then tadpoles, exit their ponds over an irregular timetable in late summer. Because of their small stature – just a couple of cm wide – "they are destroyed by vehicles." And as being hit "essentially crushes them," it's harder to get data on them. At least when mature amphibians are killed, their carcasses can be counted.

Year-Round Work

In contrast to many groups, one local team, who are in their eighth season of functioning, go out year-round – not nightly, but when weather are damp, or if someone has posted about a amphibian spotting in their group chat. When I request to accompany them on patrol, they concede it is "not a toady night" – winter dormancy has started and it's been a arid period – but several of the volunteers willingly accept to patrol their route with me and search for any toads. "Should anyone can locate any toads tonight, those two will spot one," says the patrol manager, indicating her teenage child and the longtime volunteer. We've been out for 120 minutes without a glimpse of any amphibians, and now they have climbed over a wire barrier to inspect beneath some wood.

Community Involvement

The family duo became part of the group a while back. The youngster adores all things nature-related and has an goal to become a conservationist, so his mother started to search for things they could do jointly to protect local wildlife. Now she enjoys it as much as he does, the 41-year-old small business owner tells me – so when the team was looking for a fresh coordinator recently, she decided to step up.

The youth, too, has played an important role in the organization. A video he created, urging the municipal authority to block a street through a nature reserve during breeding time, swung the decision the group's way. After a twelve months of campaigning, the authority approved an "access-only" restriction between evening and morning from late winter through to April. Most drivers duly avoided the route.

Other Wildlife and Challenges

Several vehicles go past when I'm out on patrol and we discover some victims as a result – no toads, but several crushed salamanders. We see one living newt as well, and the teenager is particularly pleased to see a harvestman, which dances in his hands. Yet despite the team's hardest attempts to show me a toad, the native community has obviously gone dormant for the colder months. It seems that I couldn't have found any better success elsewhere in the nation – all the rescue teams I reach out to explain that it's near-impossible 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 kindly taken the trouble to look for toads in a noted location, thought to be the largest accurately monitored toad population in the UK, arrives in my inbox with the title: "No toads." However, in February and March, he tells me, the group plans to assist around ten thousand mature amphibians across the road.

Effectiveness and Limitations

What level of impact can these groups truly achieve? "The fact that people are doing this consistently on chilly, wet and miserable late nights is remarkable," says an researcher. "That's something that very much deserves recognition." However, while toad patrols are able to reduce the drop, they can't stop it completely – partly since vehicles is not the only threat.

Additional Threats

The global warming has meant longer periods of dry weather, which create the wrong conditions for some of the animals that toads consume, such as invertebrates, while higher water temperatures have caused an rise of blue-green algae, which can be harmful to toads. Milder winters also cause toads to emerge from their dormancy more often, disrupting the resource preservation vital to their existence. Loss of environment – especially the loss of big water bodies – is another menace.

Researchers are "often concerned about putting too much of a utilitarian spin on wildlife," however "There is a big value in just having these animals around." But toads do have an significant part in the food chain, consuming almost any invertebrates or tiny organisms they can swallow and in turn sustaining a number of birds and mammals, such as hedgehogs and otters. Improving conditions for toads – such as creating more ponds, conserving woodland and constructing amphibian passages – "benefits for a whole bunch of other species."

Cultural Significance

An additional motive to work to preserve toads present is their "important cultural value," notes an expert. Myths and folklore around toads date back {centuries|hundred
