Can the UK's Toads Be Saved from Traffic and Population Collapse?

It is a Friday evening at 7:30, but instead of heading to the pub or watching a film, I've taken a train to a market town in Wiltshire to meet up with volunteers from a amphibian rescue group. These committed people give up their evenings to protect the local toad population.

An Alarming Drop in Numbers

The common toad is becoming increasingly uncommon. A latest study conducted by an wildlife conservation group showed that the UK toad population have almost halved since 1985. Seeing a species that has been a stalwart of the British countryside in decline is labeled "concerning" by researchers. Toads "don't need very specific conditions" and "ought to live quite well in the majority of areas in Britain," so if even they are not managing to survive, "it indicates that things are not as they should be."

The Threat from Roads

Though the study didn't examine the reasons for the drop, traffic certainly plays a part. Calculations suggest that 20 tons of toads are killed on UK roads every year – that is, several hundred thousand. Unlike frogs, which might be happy to mate "with just a bucket of water," toads prefer big bodies of water. Their capacity to stay out of water for more time than frogs allows they can travel further to reach them – often hundreds of metres. They usually follow their traditional paths – it's typical for adult toads to return to their natal pond to mate.

Migration Habits

Appropriately enough, the initial amphibians begin their quest for a mate around Valentine's day, but some move as far as April, until it gets dark and moving after sunset. During that period, toads start moving from where they have been hibernating "almost simultaneously."

A local helper, who was raised in the region and has been working to save 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 next generation of toads from being born.

Rescue Groups Throughout the United Kingdom

Finding hundreds of dead toads on local roads "resonates deeply with people," and has led to the formation of toad patrols across the UK – 274 groups are currently registered with a countrywide program. These teams collect toads and transport them across roads in containers, as well as recording the number of toads they find and lobbying for other safety solutions, such as road closures and underground wildlife tunnels.

Patrols usually work during the breeding period, when amphibian movements are frequent. However, this implies they can miss numbers of young toads, which, having been spawn and then tadpoles, leave their water habitats over an unpredictable schedule in late summer. Because of their size – just one or two centimetres wide – "they can get obliterated by car traffic." And as being run over "basically turns them into mush," it's more difficult to get data on them. At least when adult toads are lost, their remains can be counted.

Year-Round Efforts

Unlike many groups, a specific volunteer group, who are in their eighth season of operating, go out throughout the year – not every night, but whenever weather are warm and wet, or if a member has reported about a toad sighting 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 volunteers gamely agree to patrol their route with me and search for any toads. "Should anyone can locate any toads tonight, those two will find 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 climbed over a wire barrier to inspect beneath some wood.

Community Participation

The mother and son joined the group a year and a half ago. The youngster adores all things wildlife and has an ambition to become a conservationist, so his mother started to search for activities they could do together to help local wildlife. Now she loves it as much as he does, the middle-aged small business owner explains – so when the team was seeking a fresh coordinator recently, she volunteered for the role.

The youth, too, has played an important role in the group. A video he made, imploring the municipal authority to block a street through a nature reserve during migration season, swung the decision the team's way. After a twelve months of lobbying, the council approved an "access-only" restriction between 5pm and 5am from February through to April. Most drivers respected and avoided the route.

Other Wildlife and Difficulties

A few cars go by when I'm out on patrol and we discover some victims as a consequence – no amphibians, but three squashed newts. We spot one live amphibian as well, and the youngster is especially excited to see a daddy longlegs, which dances in his palms. Yet in spite of the group's hardest attempts to show me a toad, the local population has obviously settled down for the winter. It appears that I wouldn't have had any more luck elsewhere in the nation – all the patrol groups I reach out to clarify that it's near-impossible at this season.

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

A message I receive from a different helper, who has generously taken the trouble to check for toads in a noted location, considered the biggest tracked toad population in the UK, reaches me with the title: "No toads." However, in late winter, he tells me, the group expects to help approximately 10,000 mature amphibians over the street.

Impact and Challenges

What level of impact can these organizations actually make? "The reality that people are doing this consistently on chilly, wet and miserable late nights is remarkable," 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 just one danger.

Additional Threats

The global warming has meant longer periods of drought, which create the poor environment for some of the animals that toads consume, such as invertebrates, while warmer ponds have led to an rise of toxic plants, 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 existence. Habitat destruction – particularly the disappearance 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 significant part in the ecosystem, 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 hedgehogs and otters. Improving conditions for toads – such as building water habitats, conserving woodland and installing toad tunnels – "benefits for a wide range of additional wildlife."

Historical Significance

An additional motive to work to preserve toads around is their "important cultural value," adds an expert. Legends and tales around toads go back {centuries|hundred
