Conservationists in Wrexham worry that more than 1,000 toads have died after a reservoir was suddenly emptied by a water supplier over the Easter weekend. Members of Wrexham Toad Patrols, a volunteer group that has spent months helping amphibians 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 essential 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 led nearly 1,500 toads to the reservoir this year—quadruple the number from 2025.
The Breeding Season Interference
The timing of the reservoir drainage has proven particularly damaging for the toad population, as the breeding season was approaching its natural conclusion. Volunteers had expected that the toads would leave the area in 4-6 weeks, enabling them to lay their spawn and enabling the young to grow into juvenile toads before leaving. Had the utility provider delayed the essential maintenance work by this brief timeframe, the amphibians would have completed their reproductive cycle and departed of their own accord, preventing the massive death toll that volunteers now fear 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 in four to six weeks
- Spawn would have matured into toadlets before water removal
- Reservoir usually fills with male toad vocalisation throughout breeding
- Volunteers had helped nearly 1,500 toads reaching the site
Volunteering Initiatives and Ecological Impact
Many years of Dedicated Work
The volunteers of Wrexham Toad Patrols have devoted substantial resources and commitment 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 committed team frequently sacrifices their evenings to gather and safely relocate toads, frogs and newts across the busy A525 road. This year’s success in helping approximately 1,500 toads represented a remarkable success, multiplying four times the numbers from the year before as volunteer numbers swelled. The dramatic increase reflected increased public involvement with conservation efforts in the region.
The rapid emptying of the Nant-y-Ffrith reservoir has essentially undermined extensive careful efforts by the volunteers. Ella Thistleton, another member of the patrol group, highlighted the broader implications of the loss, emphasising that the reservoir sustains an whole ecological system separate from the toads themselves. The volunteers’ activities were not simply concerned with moving individual animals; they embodied a comprehensive conservation strategy intended to safeguard a sensitive ecological network. The distress caused by the reservoir’s sudden drainage during the Easter break has left the group devastated, notably since that their work was progressing well and effectively.
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 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 major threat to broader conservation efforts. With suitable spawning grounds becoming ever scarcer, the loss of this essential area threatens to intensify population reductions further, damaging years of conservation work across the region.

- Quadrupled toad numbers supported this year compared to 2025
- Ecosystem goes further than toads to newts and frogs
Wider Conservation Concerns
The emptying of Nant-y-Ffrith reservoir reveals a significant flaw in Britain’s conservation of amphibians framework. With common toad populations having plummeted by 41 per cent over four decades, based on findings by wildlife charity Froglife, the loss of breeding grounds threatens to accelerate this troubling descent. The study found the common vanishing of garden ponds as a primary driver of population decline, suggesting that reservoir systems have become disproportionately important for the survival of species. The Wrexham site constituted one of the limited number of reliable breeding grounds in the area, so its unplanned depletion proved especially harmful to conservation efforts that required years to establish and sustain.
The incident brings to light important issues about liaison among water companies and environmental organisations during critical breeding seasons. Volunteers pointed out that a postponement of just four to six weeks would have enabled toads to finish their breeding cycle, allowing the water company to carry out necessary safety measures without catastrophic consequences. The absence of prior notification or discussion with local conservation groups points to systemic failures in conservation planning procedures. As Britain encounters increasing demands to safeguard diminishing species numbers, incidents like this highlight the necessity for improved communication and collaborative planning between utility companies 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 Company Response and Future Plans
Hafren Dyfrdwy, the water company responsible for the drainage, has justified its decision by highlighting the critical nature of the safety work undertaken at the Nant-y-Ffrith reservoir. A company representative recognised the worries raised by the local community and conservation volunteers, stating that the maintenance operations was essential to ensure the reservoir stayed safe for operational needs both now and in the future. The company characterised the reservoir as a crucial drinking water supply serving the local area, indicating that safety of the infrastructure was prioritised above other factors during the Easter weekend works.
Despite acknowledging the environmental sensitivity of the situation, Hafren Dyfrdwy has not yet announced concrete plans to mitigate the impact on frog and toad numbers or to coordinate future maintenance work with environmental groups. The company’s approach has been limited to short comments defending the necessity of the work, without offering details about whether similar operations might be timed differently in future or whether engagement processes with environmental groups might be established. This lack of detailed engagement has left conservation volunteers frustrated and uncertain about how to avoid similar incidents from occurring during future breeding periods.
Safety Versus Conservation
The incident underscores a underlying disagreement between infrastructure maintenance and nature preservation in Britain’s aquatic resource management. Whilst reservoir safety work is patently vital to safeguard community wellbeing and water supplies, the coordination and poor communication created a avoidable tension through improved coordination. Ecological authorities argue that essential maintenance can be arranged to limit harm to fauna, particularly when reproduction cycles are foreseeable and relatively short-lived, demanding just slight deferrals to avert major ecological harm.
- Infrastructure safety requires routine upkeep to protect public water supplies
- Reproductive periods are predictable and comparatively brief, lasting four to six weeks
- Better collaboration could allow both safety work and conservation objectives to succeed
