Conservationists in Wrexham worry that over 1,000 toads have perished after a reservoir was unexpectedly drained by a water supplier over the Easter weekend. Members of Wrexham Toad Patrols, a volunteer group that has spent months helping amphibians securely traverse a busy road to reach their breeding ground at Nant-y-Ffrith reservoir on the Llandegla moors, expressed shock at the abrupt emptying. The Hafren Dyfrdwy water company said the work was essential for safety upgrades, but volunteers argue the timing was disastrous, as the toads were weeks away from completing their breeding season and naturally departing 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 Interference
The timing of the water drawdown has proven especially devastating for the toads, as the spawning period was nearing its end. Volunteers had anticipated that the toads would leave the area within four to six weeks, enabling them to deposit eggs and enabling the tadpoles to develop into juvenile toads before departing. Had the utility provider postponed the essential maintenance work by this brief timeframe, the creatures would have finished breeding and departed of their own accord, preventing the massive death toll that volunteers currently believe has taken place.
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 left within four to six weeks
- Spawn would have transformed into toadlets ahead of water removal
- Reservoir usually fills with male toad calls throughout breeding
- Volunteers had helped nearly 1,500 toads arriving at the site
Volunteer Efforts and Environmental Effects
Years of Dedicated Work
The volunteers of Wrexham Toad Patrols have invested considerable resources and commitment into protecting the amphibian population for many years, operating consistently during the mating period between February and May. Operating at a pair of locations—Ruthin Road and Brymbo—the committed team 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 represented a remarkable success, multiplying four times the numbers from the previous year as volunteer numbers swelled. The significant growth demonstrated growing community engagement with environmental protection work in the region.
The abrupt loss of the Nant-y-Ffrith reservoir has substantially reversed extensive careful efforts by the volunteers. Ella Thistleton, another member of the conservation group, outlined the larger impact of the loss, underlining that the reservoir sustains an complete biological community beyond the toads themselves. The volunteers’ activities were not merely about relocating single creatures; they constituted a thorough ecological approach intended to safeguard a sensitive ecological network. The shock of the reservoir’s abrupt loss during the Easter break has deeply affected the volunteers, particularly given that their work had been proceeding smoothly and successfully.
Conservation charity Froglife has documented alarming declines 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 originates in the loss of garden ponds in residential areas, making natural sites like the Nant-y-Ffrith reservoir ever more essential for species survival. The drainage therefore represents not merely a local setback but a significant blow to broader conservation efforts. With suitable reproductive sites becoming ever scarcer, the loss of this essential area threatens to intensify population reductions further, damaging years of conservation work across the region.

- Increased fourfold toad numbers supported this year compared to 2025
- Ecosystem encompasses more than toads to newts and frogs
Wider Conservation Concerns
The emptying of Nant-y-Ffrith reservoir uncovers a critical vulnerability in Britain’s conservation of amphibians approach. With common toad populations having plummeted by 41 per cent over four decades, according to research by wildlife charity Froglife, the loss of breeding grounds could accelerate this alarming decline. The investigation revealed the widespread disappearance of domestic ponds as a main cause of population collapse, indicating that natural reservoirs have assumed greater significance for the survival of species. The Wrexham site constituted one of the handful of reliable breeding grounds in the area, meaning its sudden emptying was especially detrimental to conservation initiatives that required considerable time to set up and nurture.
The incident raises serious questions about cooperation between water companies and wildlife bodies during critical breeding seasons. Volunteers pointed out that a brief delay of four to six weeks would have permitted toads to finish their breeding cycle, enabling the water company to carry out critical safety operations without devastating impacts. The absence of prior notification or consultation with local conservation groups points to systemic failures in environmental planning protocols. As Britain confronts growing pressure to preserve dwindling wildlife, incidents like this highlight the need for enhanced dialogue and joint planning between infrastructure operators and conservation stakeholders 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 Forward Strategy
Hafren Dyfrdwy, the water company responsible for the drainage, has justified its choice by emphasising the critical nature of the safety operations carried out at the Nant-y-Ffrith reservoir. A company spokesperson acknowledged the worries raised by the local community and conservation volunteers, stating that the maintenance work was essential to guarantee the reservoir remained safe for operational purposes both both currently and going forward. The company characterised the reservoir as a crucial water supply supplying the surrounding region, indicating that safety of the infrastructure was prioritised above other factors during the Easter weekend works.
Despite acknowledging the ecological importance of the situation, Hafren Dyfrdwy has not yet announced specific measures to reduce the effects on frog and toad numbers or to align upcoming maintenance activities with environmental groups. The company’s approach has been restricted to brief statements justifying the need of the work, without offering details about whether comparable work might be timed differently in coming years or whether consultation mechanisms with conservation bodies might be put in place. This lack of detailed engagement has made conservation volunteers uncertain and concerned about how to prevent comparable problems from occurring during future breeding periods.
Safety Versus Conservation
The incident highlights a underlying disagreement between facility upkeep and nature preservation in Britain’s water management sector. Whilst dam safety operations is clearly essential to ensure public safety and water provision, the timing and lack of advance notice created a avoidable tension through improved coordination. Conservation experts argue that essential maintenance can be scheduled to minimise wildlife impact, especially if breeding seasons are predictable and brief in duration, demanding just slight deferrals to prevent catastrophic ecological consequences.
- Infrastructure safety requires regular maintenance to protect community water systems
- Breeding seasons are foreseeable and relatively short, lasting four to six weeks
- Better collaboration could enable both safety work and conservation objectives to be achieved
