Conservationists in Wrexham fear that over 1,000 toads have died after a reservoir was unexpectedly drained 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 reach their breeding ground at Nant-y-Ffrith reservoir on the Llandegla moors, voiced alarm at the abrupt emptying. The Hafren Dyfrdwy water company stated the work was necessary for safety upgrades, but volunteers argue the timing was disastrous, as the toads were weeks away from finishing their spawning period and naturally departing the site. The incident has deeply affected the group, which had successfully led around 1,500 toads to the reservoir this year—four times the number from 2025.
The Breeding Season Interference
The scheduling of the water drawdown has been especially devastating for the toads, as the breeding season was approaching its end. Volunteers had anticipated that the toads would vacate the site in four to six weeks, enabling them to deposit eggs and allowing the tadpoles to develop into toadlets before leaving. Had the utility provider delayed the essential maintenance work by this brief timeframe, the creatures would have finished breeding and departed of their own accord, avoiding the catastrophic loss of life that volunteers now fear 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 departed over four to six weeks
- Spawn would have developed into toadlets ahead of water removal
- Reservoir commonly fills with male toad calls during breeding
- Volunteers had helped nearly 1,500 toads reaching the site
Volunteer Efforts and Ecological Impact
Many years of Professional Commitment
The volunteers of Wrexham Toad Patrols have devoted substantial resources and commitment into protecting the amphibian population for many years, working tirelessly during the mating period between February and May. Operating at a pair of locations—Ruthin Road and Brymbo—the dedicated group regularly gives up their evenings to collect and carefully move toads, frogs and newts across the busy A525 road. This year’s success in helping nearly 1,500 toads represented a remarkable success, quadrupling the numbers from the previous year as volunteer numbers swelled. The significant growth reflected growing community engagement 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, another member of the conservation group, outlined the wider consequences of the loss, emphasising that the reservoir sustains an entire ecosystem beyond the toads themselves. The volunteers’ efforts were not just focused on transporting individual toads; they constituted a thorough ecological approach designed to protect a sensitive ecological network. The distress caused by the reservoir’s sudden drainage during the Easter break has profoundly impacted the team, notably since that their work had been proceeding smoothly and without difficulty.
Conservation charity Froglife has recorded alarming declines in common toad populations across the United Kingdom, with research revealing a 41 per cent decrease over the past four decades. Much of this decline stems 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 major threat to broader conservation efforts. With suitable reproductive sites becoming ever scarcer, the loss of this crucial site threatens to speed up population losses further, undermining years of conservation work across the region.

- Quadrupled toad numbers supported this year compared to 2025
- Ecosystem goes further than toads to frogs and newts
Broader Conservation Concerns
The emptying of Nant-y-Ffrith reservoir uncovers a significant flaw in Britain’s amphibian conservation framework. With toad numbers having fallen by 41 per cent over 40 years, based on findings by conservation charity Froglife, the loss of breeding grounds threatens to accelerate this concerning fall. The research identified the widespread disappearance of domestic ponds as a main cause of population decline, meaning natural reservoirs have assumed greater significance for species survival. The Wrexham site was one of the handful of reliable breeding grounds in the region, making its unexpected drainage particularly damaging to conservation efforts that have taken years to establish and nurture.
The incident highlights important issues about cooperation between water companies and conservation groups during critical breeding seasons. Volunteers emphasised that a brief delay of four to six weeks would have enabled toads to finish their breeding cycle, enabling the water company to carry out essential safety work without devastating impacts. The absence of prior notification or engagement with local conservation groups indicates systemic failures in conservation planning procedures. As Britain encounters increasing demands to safeguard diminishing species numbers, incidents like this highlight the need for better communication and cooperative planning between infrastructure providers and wildlife organisations to avoid additional permanent harm to at-risk 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 Provider’s Response and Future Plans
Hafren Dyfrdwy, the water utility managing the drainage, has defended its decision by highlighting the essential nature of the safety work carried out at the Nant-y-Ffrith reservoir. A company spokesperson acknowledged the worries expressed by the local community and conservation volunteers, noting that the maintenance work was essential to ensure the reservoir remained safe for operational purposes both both currently and going forward. The company described the reservoir as a vital water supply serving the local area, indicating that safety of the infrastructure was prioritised above other factors during the Easter weekend works.
Despite recognising the ecological importance of the situation, Hafren Dyfrdwy has not yet announced concrete plans to reduce the effects on amphibian populations or to coordinate upcoming maintenance activities with conservation organisations. The company’s response has been limited to brief statements justifying the need of the work, without offering details about whether comparable work 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 frustrated and uncertain about how to prevent comparable problems from occurring during future breeding periods.
Safety Versus Conservation
The incident underscores a fundamental tension between structural preservation and ecological conservation in Britain’s water management sector. Whilst reservoir safety work is patently vital to safeguard community wellbeing and water provision, the coordination and poor communication created a avoidable tension through improved coordination. Ecological authorities argue that essential maintenance can be timed to reduce harm to fauna, particularly when reproduction cycles are foreseeable and relatively short-lived, demanding just slight deferrals to prevent catastrophic ecological consequences.
- Infrastructure safety requires regular maintenance to protect community water systems
- Breeding seasons are predictable and comparatively brief, running between four and six weeks
- Better collaboration could allow safety initiatives and conservation goals to succeed
