It's Friday night at half past seven, but rather than heading to the pub or relaxing at home, I've taken a train to a market town in Wiltshire to meet up with local helpers from a toad patrol. These committed people give up their nights to protect the native amphibian community.

A Worrying Decline in Numbers

The Bufo bufo is becoming increasingly rare. A latest research conducted by an amphibian and reptile charity showed that the UK toad population have dropped by half since the mid-1980s. Observing a species that has been a stalwart of the UK landscape in decline is labeled "concerning" by researchers. Toads "don't require very specific conditions" and "ought to live quite well in most of areas in Britain," meaning if even they are struggling to persist, "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 reasons for the decline, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are killed on British roads every year – in other words, hundreds of thousands. Unlike frogs, which might be happy to mate "with just a small container," toads favor big bodies of water. Their ability to stay out of water for longer than frogs allows they can travel further to reach them – often hundreds of metres. They usually stick to their traditional paths – 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 some move as late as spring, waiting until it gets night and moving after sunset. During that time, toads begin migrating from wherever they have been hibernating "almost simultaneously."

A local helper, who grew up in the area and has been working to save its amphibians since he was a boy, notes that "They've got just one focus: to go and have an orgy." If their path happens to a street, they could be killed by traffic, and that mating period would be lost – stopping a next generation of toads from being produced.

Toad Patrols Throughout the United Kingdom

Seeing many of toad carcasses on local roads "resonates deeply with people," and has led to the creation of toad patrols throughout the UK – 274 groups are currently registered with a countrywide program. These teams pick up toads and transport them over streets in containers, as well as counting the quantity of toads they encounter and lobbying for other safety solutions, such as blocked roads and underground wildlife tunnels.

Patrols tend to operate during the breeding period, when amphibian movements are frequent. However, this implies they can overlook groups of toadlets, which, having existed as eggs and then tadpoles, exit their ponds over an irregular timetable in the end of summer. Because of their size – just a couple of cm wide – "they are destroyed by car traffic." And as being hit "essentially crushes them," it's harder to get data on them. At least when adult toads are lost, their remains can be counted.

Year-Round Work

In contrast to many groups, one local team, who are in their eighth season of operating, go out year-round – not every night, but when conditions are damp, or if a member has reported about a toad sighting in their group chat. When I request to accompany them on patrol, they concede it is "not a toady night" – toad hibernation season has begun and it's been a dry day – but several of the volunteers willingly accept to walk up and down their route with me and search for any toads. "Should anyone can find any toads tonight, that pair will spot one," says the patrol manager, pointing to her 14-year-old son and the longtime volunteer. We've been out for two hours without a single toad sighting, and now they have climbed over a barbed wire fence to check under some wood.

Community Participation

The mother and son joined the group a year and a half ago. The teenager loves all things wildlife and has an ambition to become a environmentalist, so his parent started to look for things they could do jointly to protect local wildlife. Now she loves it as much as he does, the middle-aged small business owner tells me – so when the team was seeking a fresh coordinator recently, she decided to step up.

The teenager, too, has played an important role in the organization. A video he made, urging the local council to close a road through a nature reserve during migration season, swung the decision the team's way. After a year of lobbying, the council agreed to an "access-only" rule between evening and morning from late winter through to April. Most drivers respected and avoided the route.

Other Wildlife and Challenges

Several vehicles go by when I'm out on patrol and we discover some victims as a result – no amphibians, but three squashed newts. We see one living newt as well, and the teenager is particularly pleased to see a harvestman, which dances in his palms. Yet despite the team's best efforts to let me see a toad, the local population has obviously settled down for the colder months. It seems that I couldn't have found any more luck elsewhere in the country – all the patrol groups I contact clarify that it's very difficult at this season.

This team anticipates assisting around ten thousand mature toads over the street

One email I get from a different helper, who has generously made the effort to look for toads in a noted location, thought to be the biggest tracked toad group in the UK, reaches me with the title: "None found." However, in late winter, he tells me, the team expects to help approximately ten thousand mature amphibians across the road.

Effectiveness and Limitations

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

Additional Threats

The climate crisis has meant extended spells of dry weather, which create the wrong conditions for some of the animals that toads eat, such as invertebrates, while higher water temperatures have caused an increase of blue-green algae, which can be toxic to toads. Milder winters also cause toads to emerge from their dormancy more frequently, interfering with the resource preservation crucial to their life cycle. Loss of environment – particularly the loss of large ponds – is an additional threat.

Researchers are "always a bit worried about putting too much of a utilitarian spin on biodiversity," however "There is a big value in just their presence." But toads do have an important role in the food chain, eating pretty much any invertebrates or tiny organisms they can swallow and in turn sustaining a number of birds and mammals, such as wildlife. Enhancing situations for toads – ie building water habitats, conserving woodland and installing toad tunnels – "benefits for a whole bunch of other species."

Historical Significance

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