Conservationists in Wrexham worry that more than 1,000 toads have perished after a reservoir was suddenly emptied by a water supplier over the Easter weekend. Members of Wrexham Toad Patrols, a volunteer group that has devoted months assisting toads safely cross a busy road to access their spawning site at Nant-y-Ffrith reservoir on the Llandegla moors, voiced alarm at the sudden drainage. The Hafren Dyfrdwy water company stated the work was necessary for safety improvements, but volunteers contend the timing was catastrophic, as the toads were weeks away from finishing their spawning period and naturally leaving the site. The incident has deeply affected the group, which had successfully guided nearly 1,500 toads to the reservoir this year—four times the number from 2025.
The Breeding Season Disruption
The scheduling of the reservoir drainage has proven particularly devastating for the toads, as the spawning period was approaching its end. Volunteers had expected that the toads would leave the area in four to six weeks, enabling them to lay their spawn and allowing the tadpoles to develop into toadlets before leaving. Had the water company postponed the essential maintenance work by this relatively short period, the creatures would have finished breeding and left the reservoir of their own accord, avoiding the catastrophic loss of life that volunteers currently believe has occurred.
Becky Wiseman, a dedicated volunteer with Wrexham Toad Patrols, described the eerie silence that greeted them upon visiting the drained reservoir. “The males are very vocal so you can usually hear them. It was silent,” she said, noting that the group saw no signs of life when they approached as close as possible to the site. The absence of the characteristic croaking sounds that typically fill the reservoir during breeding season served as a grim indicator of the likely outcome. Fellow volunteer Teri Davies expressed the group’s anguish, saying: “All of us are totally gutted, all that hard work and it’s just gone.”
- Toads would have naturally migrated within four to six weeks
- Spawn would have developed into toadlets ahead of water removal
- Reservoir usually fills with male toad vocalisation during breeding
- Volunteers had assisted around 1,500 toads getting to the site
Volunteer Efforts and Environmental Effects
Years of Professional Commitment
The volunteers of Wrexham Toad Patrols have invested considerable time and effort into protecting the amphibian population for many years, working tirelessly during the breeding season between February and May. Operating at two sites—Ruthin Road and Brymbo—the dedicated group regularly gives up their evenings to gather and safely relocate toads, frogs and newts across the busy A525 road. This year’s achievement of assisting nearly 1,500 toads demonstrated impressive results, multiplying four times the numbers from the previous year as volunteer numbers swelled. The dramatic increase reflected increased public involvement with environmental protection work in the region.
The sudden drainage of the Nant-y-Ffrith reservoir has effectively negated extensive careful efforts by the volunteers. Ella Thistleton, one of the members of the conservation group, expressed the broader implications of the loss, emphasising that the reservoir sustains an entire ecosystem beyond the toads themselves. The volunteers’ work were not just focused on moving individual animals; they embodied a complete protection plan designed to protect a fragile natural system. The shock of the reservoir’s sudden drainage during the Easter break has deeply affected the volunteers, notably since that their work had been proceeding smoothly and effectively.
Conservation charity Froglife has documented concerning population drops in common toad populations across the United Kingdom, with research indicating a 41 per cent decrease over the last 40 years. Much of this decline results from the loss of garden ponds in housing areas, making natural sites like the Nant-y-Ffrith reservoir increasingly vital for species survival. The drainage therefore represents not merely a localised issue but a significant blow to broader conservation efforts. With suitable spawning grounds becoming ever scarcer, the loss of this vital location threatens to speed up population losses further, undermining years of conservation work across the region.

- Increased fourfold toad numbers supported this year versus 2025
- Ecosystem extends beyond toads to frogs and newts
Extended Sustainability Challenges
The emptying of Nant-y-Ffrith reservoir reveals a critical vulnerability in Britain’s conservation of amphibians strategy. With common toad populations having fallen by 41 per cent over 40 years, based on findings by wildlife charity Froglife, the removal of established breeding sites risks accelerate this troubling descent. The investigation revealed the widespread disappearance of domestic ponds as a leading factor of population collapse, meaning natural reservoirs have become disproportionately important for species survival. The location in Wrexham represented one of the few remaining reliable breeding grounds in the area, so its unplanned depletion proved especially detrimental to conservation efforts that have taken years to establish and nurture.
The incident raises important issues about coordination between water companies and conservation groups during critical breeding seasons. Volunteers emphasised that a postponement of just four to six weeks would have permitted toads to conclude their reproduction, allowing the water company to undertake necessary safety measures without devastating impacts. The lack of advance notice or discussion with local conservation groups indicates systemic failures in ecological planning frameworks. As Britain encounters increasing demands to preserve dwindling wildlife, incidents like this underscore the requirement for better communication and joint planning between infrastructure operators and environmental partners to prevent further irreversible damage to vulnerable species.
| Species Affected | Habitat Impact |
|---|---|
| Common Toads | Loss of ancestral breeding ground; population decline accelerated |
| Frogs | Destruction of breeding habitat supporting entire amphibian community |
| Newts | Elimination of critical spawning site; ecosystem disruption |
| Aquatic Invertebrates | Collapse of food chain supporting amphibian populations |
Water Supplier’s Response and Upcoming Initiatives
Hafren Dyfrdwy, the water company responsible for the drainage, has justified its choice by highlighting the essential nature of the safety work carried out at the Nant-y-Ffrith reservoir. A company spokesperson acknowledged the concerns expressed by the local residents and conservation volunteers, noting that the maintenance work was vital to guarantee the reservoir stayed safe for operational needs both now and in the future. The company characterised the reservoir as a crucial water supply supplying the surrounding region, indicating that infrastructure safety was prioritised above other considerations throughout the Easter weekend works.
Despite recognising the ecological importance of the situation, Hafren Dyfrdwy has not yet announced concrete plans to mitigate the impact on frog and toad numbers or to align future maintenance work with conservation organisations. The company’s approach has been restricted to brief statements defending the necessity of the work, without offering details about whether similar operations might be scheduled differently in future or whether engagement processes with environmental groups might be established. This lack of detailed engagement has made conservation volunteers uncertain and concerned about how to avoid comparable problems from occurring during subsequent breeding seasons.
Safety Versus Conservation
The incident highlights a core conflict between facility upkeep and environmental protection in Britain’s water supply industry. Whilst water storage facility maintenance is clearly essential to ensure public safety and water supplies, the coordination and poor communication created a preventable dispute through more careful scheduling. Ecological authorities argue that necessary upkeep can be timed to reduce wildlife impact, particularly when reproduction cycles are foreseeable and relatively short-lived, requiring only modest delays to avert major ecological harm.
- System protection requires regular maintenance to safeguard public water supplies
- Breeding seasons are foreseeable and relatively short, running four to six weeks
- Improved coordination could allow both safety work and conservation objectives to succeed
