It is Friday night at half past seven, but instead of going out or relaxing at home, I've caught a train to a market town in Wiltshire to join volunteers from a amphibian rescue group. These committed people sacrifice their nights to protect the native amphibian community.

A Worrying Decline in Population

The Bufo bufo is becoming increasingly uncommon. A recent study conducted by an amphibian and reptile charity showed that the British common toad numbers have almost halved since 1985. Observing a creature that has been a fixture of the UK landscape in decline is described as "worrying" by experts. Toads "don't need very particular environments" and "should be able to live quite well in the majority of areas in Britain," so if even they are struggling to persist, "it kind of suggests that the ecosystem is unbalanced."

Since 1985, Britain's toad numbers have nearly been cut in half

The Threat from Traffic

Though the research didn't examine the reasons for the drop, traffic certainly plays a part. Calculations indicate that 20 tons of toads are killed on British roads annually – in other words, hundreds of thousands. In contrast to frogs, which would probably be content to mate "with just a small container," toads favor big bodies of water. Their capacity to remain away from water for more time than frogs allows they can travel further to reach them – often long distances. They usually follow their ancestral migration routes – it's typical for mature amphibians to go back to their natal pond to mate.

Migration Habits

Fittingly, the initial amphibians start their journey for a partner around Valentine's day, but some move as late as April, waiting until it gets night and travelling through the night. During that time, toads start moving from where they have been overwintering "almost simultaneously."

A local helper, who grew up in the region and has been working to save its amphibians since he was a child, notes that "Their sole purpose: to go and mate." If their path crosses a street, they could be killed by traffic, and that breeding season would be lost – preventing a next generation of toads from being produced.

Toad Patrols Across the UK

Finding many of dead toads on nearby streets "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 groups pick up toads and transport them across roads in buckets, as well as counting the number of toads they encounter and lobbying for other protection measures, such as blocked roads and underground wildlife tunnels.

Volunteers usually work during the migration season, when toad crossings are more regular. However, this implies they can overlook groups of toadlets, which, having existed as spawn and then tadpoles, exit their water habitats over an unpredictable schedule 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 more difficult to get data on them. At least when mature amphibians are killed, their remains can be counted.

Year-Round Efforts

In contrast to many groups, a specific volunteer group, who are in their eighth year of operating, 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 admit it is "not ideal conditions" – toad hibernation season has started and it's been a dry day – but several of the helpers willingly accept to patrol their route with me and see what we can find. "Should anyone can find any toads tonight, those two will find one," says the patrol manager, pointing to her teenage child and the longtime volunteer. After for 120 minutes without a single toad sighting, and now they have scaled a wire barrier to check under some logs.

Community Participation

The family duo joined the group a while back. The teenager adores all things wildlife and has an goal to become a conservationist, so his parent started to look for activities they could do together to help native animals. Now she enjoys it as much as he does, the 41-year-old entrepreneur tells me – so when the team was looking for a fresh coordinator lately, she volunteered for the role.

The youth, too, has been instrumental in the group. A video he created, urging the local council to close a street through a protected area during breeding time, swung the decision the team's way. After a year of campaigning, the authority agreed to an "restricted access" rule between 5pm and 5am from late winter through to spring. The majority of motorists duly avoided the route.

Additional Species and Difficulties

Several cars go by when I'm out on patrol and we find some victims as a result – no amphibians, but several crushed salamanders. We spot one living newt as well, and the youngster is particularly pleased to see a harvestman, which moves in his palms. Yet in spite of the group's hardest attempts to show me a toad, the local population has clearly gone dormant for the colder months. It appears that I wouldn't have had any better success anywhere else in the country – all the patrol groups I reach out to explain that it's very difficult at this season.

One email I get from a different helper, who has kindly taken the trouble 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 February and March, he tells me, the group expects to help approximately ten thousand mature amphibians across the road.

Effectiveness and Limitations

How much of a difference can these organizations truly achieve? "The reality that people are performing this consistently on cold, damp and unpleasant evenings is remarkable," 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 – partly since vehicles is not the only threat.

Additional Threats

The climate crisis has resulted in extended spells of drought, which create the wrong conditions for some of the creatures that toads eat, such as worms and slugs, while higher water temperatures have led to an increase of blue-green algae, which can be harmful to toads. Warmer cold seasons also cause toads to wake up from their dormancy more frequently, interfering with the resource preservation crucial to their life cycle. Loss of environment – especially the loss of big water bodies – is another menace.

Researchers are "often concerned about overemphasizing practical benefits on wildlife," however "It's important in just having these animals around." But toads play an significant part in the food chain, eating 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 wildlife. Improving situations for toads – ie creating more ponds, protecting forests and installing toad tunnels – "benefits for a wide range of additional wildlife."

Cultural Importance

Another reason to try to keep toads present is their "important cultural value," notes an specialist. Legends and tales around toads date back {centuries|hundred
