Will the UK's Toads Survive from Traffic and Population Collapse?

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

A Worrying Decline in Population

The common toad is becoming increasingly rare. A latest research conducted by an wildlife conservation group showed that the British common toad numbers have almost halved since the mid-1980s. Observing a species that has been a stalwart of the British countryside in decline is described as "concerning" by experts. Toads "don't need very particular environments" and "should be able to live successfully in most of areas in the UK," meaning if even they are not managing to survive, "it indicates that things are not as they should be."

The Threat from Traffic

Though the study didn't cover the causes for the decline, cars certainly plays a part. Calculations suggest that 20 tonnes of toads are killed on UK roads annually – that is, hundreds of thousands. Unlike frogs, which might be content to mate "if you left out a bucket of water," toads prefer large ponds. Their capacity to remain away from water for more time than frogs means they can travel further to reach them – often hundreds of metres. They tend to stick to their traditional paths – it's typical for mature amphibians to go back to their birth pond to mate.

Breeding Habits

Appropriately enough, the first toads start their journey for a mate around February 14th, but some move as late as spring, waiting until it gets night and travelling through the night. During that period, toads begin migrating from where they have been hibernating "almost simultaneously."

A local helper, who grew up in the region and has been trying to protect its amphibians since he was a boy, explains that "They've got just one focus: to go and mate." If their path crosses a street, they could be killed by traffic, and that breeding season would never happen – preventing a new generation of toads from being born.

Toad Patrols Across the UK

Finding hundreds of toad carcasses on nearby streets "resonates deeply with people," and has led to the creation of rescue teams across the UK – hundreds of organizations are officially listed with a countrywide program. These groups collect toads and transport them over streets in containers, as well as recording the number of toads they find and lobbying for other safety solutions, such as road closures and amphibian passages.

Volunteers usually work during the migration season, when amphibian movements are more regular. However, this implies they can overlook groups of young toads, which, having existed as eggs and then tadpoles, leave their ponds over an unpredictable schedule in the end of summer. Because of their small stature – 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 killed, their carcasses can be counted.

Year-Round Efforts

Unlike most patrols, a specific volunteer group, who are in their eighth year of functioning, go out throughout the year – not nightly, but whenever weather are warm and wet, or if a member has posted about a toad sighting in their messaging app. When I ask to join them on duty, they concede it is "not a toady night" – winter dormancy has begun and it's been a arid period – but a few of the helpers willingly accept to patrol their route with me and search for any toads. "Should anyone can find any toads tonight, that pair will spot one," says the group coordinator, pointing to her 14-year-old son and the experienced member. After for 120 minutes without a glimpse of any amphibians, and now they have scaled a wire barrier to check under some wood.

Community Participation

The family duo became part of the group a while back. The youngster loves all things wildlife and has an goal to become a environmentalist, so his parent started to search for things they could do together to help local wildlife. Now she enjoys it as much as he does, the middle-aged small business owner tells me – so when the team was seeking a fresh coordinator lately, she volunteered for the role.

The youth, too, has been instrumental in the organization. A video he created, imploring the municipal authority to close a road through a nature reserve during migration season, influenced the outcome the group's way. After a year of lobbying, the authority agreed to an "restricted access" rule between evening and morning from late winter through to April. Most drivers duly avoided the road.

Additional Species and Challenges

Several vehicles go past when I'm out on patrol and we discover some casualties as a consequence – no amphibians, but several crushed salamanders. We see one live amphibian as well, and the teenager is especially excited to see a daddy longlegs, which dances in his hands. Yet in spite of the team's hardest attempts to let me see a toad, the local population has obviously gone dormant for the colder months. It appears that I wouldn't have had any better success anywhere else in the country – all the rescue teams I reach out to clarify that it's very difficult at this time of year.

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

A message I receive from another volunteer, who has generously made the effort to look for toads in a noted location, considered the largest accurately monitored toad population in the UK, arrives in my inbox with the subject line: "None found." However, in February and March, he informs me, the group expects to help approximately 10,000 adult toads over the street.

Effectiveness and Limitations

How much of a difference can these groups actually make? "The reality that people are doing this regularly on chilly, wet and miserable late nights is quite extraordinary," says an expert. "This effort that very much should be celebrated." However, while toad patrols are able to slow the decline, they cannot prevent it entirely – not least because vehicles is just one danger.

Other Dangers

The climate crisis has meant longer periods of drought, which create the wrong conditions for some of the animals that toads eat, such as worms and slugs, while higher water temperatures have caused an rise of toxic plants, which can be toxic to toads. Warmer cold seasons also lead toads to emerge from their dormancy more frequently, interfering with the energy conservation crucial to their life cycle. Loss of environment – particularly the loss of large ponds – is an additional threat.

Experts are "always a bit worried about overemphasizing practical benefits on biodiversity," however "There is a big value in just their presence." But toads do have an important role in the ecosystem, consuming pretty much any invertebrates or tiny organisms they can fit in their mouths and in turn feeding a number of birds and mammals, such as wildlife. Enhancing situations for toads – ie creating more ponds, protecting forests and constructing toad tunnels – "benefits for a wide range of other species."

Cultural Importance

Another reason to try to keep toads around is their "historical significance," notes an specialist. Myths and folklore around toads go back {centuries|hundred
