It is a Friday evening at 7:30, but instead of going out or watching a film, I've taken a train to a market town in Wiltshire to join volunteers from a amphibian rescue group. These dedicated individuals sacrifice their evenings to safeguard the local toad population.

A Worrying Decline in Population

The common toad is becoming increasingly uncommon. A recent study conducted by an amphibian and reptile charity revealed that the UK toad population have dropped by half since the mid-1980s. Observing a creature that has been a stalwart of the UK landscape in decrease is described as "worrying" by experts. Toads "don't need very particular environments" and "should be able to live quite well in most of areas in the UK," meaning if even they are not managing to survive, "it kind of suggests that the ecosystem is unbalanced."

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 drop, cars is a major factor. Estimates suggest that 20 tons of toads are killed on UK roads annually – in other words, several hundred thousand. Unlike frogs, which might be content to mate "with just a bucket of water," toads prefer large ponds. Their capacity to remain away from water for longer than frogs allows they can journey farther to reach them – often long distances. They tend to follow their traditional paths – it's typical for mature amphibians to return to their natal pond to mate.

Breeding Patterns

Appropriately enough, the initial amphibians start their journey for a partner around Valentine's day, but others travel as far as April, waiting until it gets night and travelling after sunset. During that period, toads begin migrating from where they have been hibernating "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, explains that "Their sole purpose: to go and mate." If their path crosses a road, they could be killed by traffic, and that mating period would never happen – stopping a next generation of toads from being born.

Toad Patrols Throughout the UK

Finding hundreds of toad carcasses on nearby streets "resonates deeply with people," and has resulted in the formation of rescue teams throughout the UK – 274 groups are currently registered with a national initiative. These groups collect toads and transport them across roads in containers, as well as counting the quantity of toads they find and lobbying for other protection measures, such as blocked roads and amphibian passages.

Patrols tend to operate during the migration season, when amphibian movements are frequent. However, this means they can miss numbers of young toads, which, having existed as spawn and then juveniles, leave their water habitats over an unpredictable schedule in the end of summer. Because of their small stature – just one or two centimetres wide – "they can get obliterated by car traffic." And as being hit "essentially crushes them," it's harder to get data on them. At least when adult toads are killed, their carcasses can be tallied.

Year-Round Efforts

Unlike most patrols, one local team, who are in their eighth year of operating, go out throughout the year – not nightly, but when conditions are damp, or if someone has posted about a amphibian spotting in their messaging app. When I ask to join them on patrol, they concede it is "not a toady night" – toad hibernation season has begun and it's been a arid period – but several of the volunteers gamely agree to patrol their route with me and search for any toads. "Should anyone can find any toads tonight, those two will spot one," says the group coordinator, indicating her 14-year-old son and the experienced member. After for 120 minutes without a glimpse of any amphibians, and now they have climbed over a wire barrier to check under some wood.

Community Participation

The mother and son became part of the group a while back. The youngster adores all things nature-related and has an ambition to become a conservationist, so his parent started to look for things they could do together to protect local wildlife. Now she loves it as much as he does, the middle-aged entrepreneur tells me – so when the team was looking for a fresh coordinator recently, she decided to step up.

The teenager, too, has been instrumental in the organization. A clip he made, imploring the local council to block a street through a nature reserve during migration season, influenced the outcome the group's way. After a twelve months of campaigning, 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

Several vehicles go by when I'm out on duty and we discover some casualties as a consequence – no amphibians, but several crushed salamanders. We spot one living newt as well, and the teenager is especially excited to see a harvestman, which dances in his palms. Yet in spite of the team's best efforts to let me see a toad, the local population has clearly settled down for the winter. It seems that I wouldn't have had any more luck elsewhere in the country – all the patrol groups I contact explain that it's very difficult at this season.

The group expects to help approximately 10,000 adult toads across the road

One email I receive from another volunteer, who has kindly made the effort to check for toads in a famous site, considered the largest accurately monitored toad population in the UK, reaches me with the subject line: "None found." However, in February and March, he informs me, the group plans to assist around 10,000 adult toads over the street.

Effectiveness and Limitations

What level of impact can these organizations actually make? "The fact that volunteers are performing this consistently on chilly, wet and miserable late nights is quite extraordinary," says an researcher. "That's something that very much should be celebrated." However, while rescue teams are able to slow the decline, they cannot prevent it entirely – partly since vehicles is not the only threat.

Additional Threats

The global warming has resulted in longer periods 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 toxic plants, which can be toxic to toads. Milder winters also lead toads to emerge from their hibernation more frequently, disrupting the resource preservation crucial to their existence. Habitat destruction – especially the disappearance of big water bodies – is an additional threat.

Experts are "often concerned about overemphasizing practical benefits 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, eating pretty much any small creatures or tiny organisms they can fit in their mouths and in turn feeding a number of predators, such as wildlife. Improving situations for toads – ie building water habitats, protecting forests and constructing toad tunnels – "we'll improve them for a whole bunch of other species."

Historical Importance

An additional motive to work to preserve toads around is their "historical significance," adds an specialist. Myths and folklore around toads date back {centuries|hundred
