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 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 said the work was essential for safety improvements, 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 led around 1,500 toads to the reservoir this year—quadruple the number from 2025.
The Mating Period Interference
The scheduling of the water drawdown has proven especially devastating for the toads, as the spawning period was approaching its natural conclusion. 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 juvenile toads before leaving. Had the water company delayed the essential maintenance work by this relatively short period, the amphibians would have finished breeding and left the reservoir of their own accord, preventing the massive death toll 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 left in four to six weeks
- Spawn would have developed into toadlets ahead of water removal
- Reservoir usually fills with male toad calls during breeding
- Volunteers had helped nearly 1,500 toads getting to the site
Volunteer Efforts and Ecological Impact
Many years of Consistent Effort
The volunteers of Wrexham Toad Patrols have invested considerable resources and commitment into protecting the amphibian population for years, operating consistently during the breeding season 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 achievement of assisting nearly 1,500 toads demonstrated impressive results, multiplying four times the numbers from the year before as volunteer numbers swelled. The significant growth reflected increased public involvement with conservation efforts in the region.
The sudden drainage of the Nant-y-Ffrith reservoir has effectively negated prolonged meticulous labour by the volunteers. Ella Thistleton, a fellow member of the conservation group, highlighted the broader implications of the loss, emphasising that the reservoir maintains an complete biological community beyond the toads themselves. The volunteers’ activities were not merely about transporting individual toads; they embodied a complete protection plan designed to protect a sensitive ecological network. The distress caused by the reservoir’s unexpected emptying over the Easter weekend has deeply affected the volunteers, notably since that their work had been proceeding smoothly and effectively.
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 previous four decades. Much of this decline results 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 localised issue but a significant blow to broader conservation efforts. With suitable reproductive sites becoming ever scarcer, the loss of this vital location threatens to intensify population reductions further, compromising years of conservation work across the region.

- Quadrupled toad numbers supported this year versus 2025
- Ecosystem goes further than toads to frogs and newts
Extended Conservation Concerns
The emptying of Nant-y-Ffrith reservoir exposes a significant flaw in Britain’s amphibian conservation framework. With common toad populations having plummeted by 41 per cent over four decades, according to research by wildlife charity Froglife, the disappearance of established breeding sites risks accelerate this alarming decline. The research identified the common vanishing of garden ponds as a primary driver of population decline, suggesting that reservoir systems have grown increasingly vital for the survival of species. The Wrexham site constituted one of the handful of dependable breeding sites in the area, meaning its sudden emptying was especially harmful to conservation work that required years to establish and develop.
The incident highlights serious questions about coordination between water companies and conservation groups during critical breeding seasons. Volunteers stressed that a postponement of just four to six weeks would have allowed toads to complete their reproductive cycle, allowing the water company to undertake essential safety work without catastrophic consequences. The absence of prior notification or consultation with local environmental organisations points to widespread failures in environmental planning protocols. As Britain confronts growing pressure to safeguard diminishing species numbers, incidents like this emphasise the requirement for better communication and collaborative planning between infrastructure providers and conservation stakeholders to stop further irreversible 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 defended its decision by emphasising the critical nature of the safety operations carried out at the Nant-y-Ffrith reservoir. A company spokesperson recognised the worries raised by the local residents and conservation volunteers, noting that the maintenance operations was vital to guarantee the reservoir remained safe for operational needs both now and in the future. The company described the reservoir as a vital water supply supplying the surrounding region, suggesting that infrastructure safety took precedence over other factors during the Easter weekend works.
Despite acknowledging the ecological importance of the situation, Hafren Dyfrdwy has still not announced specific measures to mitigate the impact on frog and toad numbers or to align future maintenance work with conservation organisations. The company’s approach has been limited to brief statements defending the necessity of the work, without providing information about whether comparable work might be timed differently in future or whether engagement processes 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 subsequent breeding seasons.
Safety Versus Conservation
The incident highlights a fundamental tension between facility upkeep and ecological conservation in Britain’s water management sector. Whilst reservoir safety work is patently vital to protect public health and water supplies, the timing and lack of advance notice created a preventable dispute through better planning. Environmental specialists argue that critical work can be scheduled to minimise harm to fauna, especially if mating periods follow patterns and brief in duration, needing merely minor postponements to avert major ecological harm.
- Infrastructure safety requires regular maintenance to protect public water supplies
- Breeding seasons are foreseeable and comparatively brief, running between four and six weeks
- Improved coordination could allow safety initiatives and conservation goals to be achieved
