Conservationists in Wrexham fear 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 devoted 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 said the work was necessary for safety improvements, 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 devastated the group, which had successfully led nearly 1,500 toads to the reservoir this year—quadruple the number from 2025.
The Mating Period Disruption
The scheduling of the reservoir drainage has proven especially devastating for the toad population, as the spawning period was approaching its natural conclusion. Volunteers had expected that the toads would vacate the site within 4-6 weeks, allowing them to deposit eggs and allowing the tadpoles to develop into toadlets before leaving. Had the utility provider postponed the necessary maintenance by this brief timeframe, the creatures would have finished breeding and left the reservoir of their own accord, preventing the catastrophic loss of life 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 departed within four to six weeks
- Spawn would have transformed into toadlets prior to water removal
- Reservoir usually fills with male toad vocalisation throughout breeding
- Volunteers had supported approximately 1,500 toads arriving at the site
Volunteering Initiatives and Ecological Impact
Many years of Professional Commitment
The volunteers of Wrexham Toad Patrols have invested considerable resources and commitment into safeguarding the amphibian population for years, working tirelessly during the mating period between February and May. Operating at two sites—Ruthin Road and Brymbo—the dedicated group 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, quadrupling the numbers from the previous year as volunteer numbers increased. The significant growth reflected increased public involvement with environmental protection work in the region.
The abrupt loss of the Nant-y-Ffrith reservoir has essentially undermined prolonged meticulous labour by the volunteers. Ella Thistleton, another member of the patrol group, outlined the wider consequences of the loss, stressing that the reservoir maintains an whole ecological system beyond the toads themselves. The volunteers’ efforts were not simply concerned with transporting individual toads; they embodied a thorough ecological approach designed to protect a sensitive ecological network. The shock of the reservoir’s sudden drainage over the Easter weekend has left the group devastated, particularly given that their work had been proceeding smoothly and effectively.
Conservation charity Froglife has recorded troubling decreases 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 critically important for species survival. The drainage therefore represents not merely a regional problem but a major threat to broader conservation efforts. With suitable breeding habitats becoming ever scarcer, the loss of this essential area threatens to accelerate population declines further, compromising years of conservation work across the region.

- Quadrupled toad numbers assisted this year compared to 2025
- Ecosystem encompasses more than toads to newts and frogs
Extended Conservation Concerns
The emptying of Nant-y-Ffrith reservoir reveals a serious weakness in Britain’s conservation of amphibians framework. With toad numbers having plummeted by 41 per cent over 40 years, according to research by conservation charity Froglife, the removal of established breeding sites threatens to accelerate this troubling descent. The investigation revealed the common vanishing of garden ponds as a main cause of population collapse, indicating that natural reservoirs have become disproportionately important for species survival. The Wrexham site was one of the limited number of dependable breeding sites in the region, so its unplanned depletion proved especially harmful to conservation initiatives that required years to establish and develop.
The incident highlights significant concerns about cooperation between water companies and environmental organisations during vital breeding times. Volunteers emphasised that a brief delay of four to six weeks would have enabled toads to finish their breeding cycle, allowing the water company to carry out necessary safety measures without severe repercussions. The absence of prior notification or discussion with local environmental organisations points to widespread failures in environmental planning protocols. As Britain confronts growing pressure to protect declining wildlife populations, incidents like this emphasise the need for improved communication and cooperative planning between infrastructure operators and environmental partners 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 Upcoming Initiatives
Hafren Dyfrdwy, the water utility managing the drainage, has defended its choice by highlighting the essential nature of the safety work carried out at the Nant-y-Ffrith reservoir. A company representative acknowledged the concerns expressed by the local residents and conservation volunteers, stating that the maintenance work was vital to guarantee the reservoir stayed safe for operational purposes both now and in the future. The company described the reservoir as a vital water supply serving the local area, indicating that safety of the infrastructure took precedence over other factors during the Easter weekend works.
Despite acknowledging the ecological importance of the situation, Hafren Dyfrdwy has not yet announced specific measures to mitigate the impact on frog and toad numbers or to align future maintenance work with environmental groups. 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 timed differently in coming years or whether consultation mechanisms with conservation bodies might be put in place. This absence of thorough consultation has left conservation volunteers frustrated and uncertain about how to avoid similar incidents from occurring during future breeding periods.
Safety Versus Conservation
The incident highlights a core conflict between infrastructure maintenance and ecological conservation in Britain’s water supply industry. Whilst reservoir safety work is clearly essential to protect public health and water provision, the timing and lack of advance notice created a preventable dispute through more careful scheduling. Environmental specialists argue that critical work can be arranged to limit wildlife impact, especially if reproduction cycles are foreseeable and relatively short-lived, requiring only modest delays to avoid severe environmental damage.
- System protection requires routine upkeep to safeguard community water systems
- Reproductive periods are predictable and comparatively brief, lasting four to six weeks
- Improved coordination could enable safety initiatives and conservation goals to succeed
