Conservationists in Wrexham worry that more than 1,000 toads have died after a reservoir was suddenly emptied by a water company over the Easter weekend. Members of Wrexham Toad Patrols, a voluntary organisation that has spent months assisting toads securely traverse a busy road to reach their breeding ground at Nant-y-Ffrith reservoir on the Llandegla moors, voiced alarm at the sudden drainage. The Hafren Dyfrdwy water company said the work was essential for safety upgrades, but volunteers argue the timing was catastrophic, as the toads were weeks away from completing their breeding season and naturally leaving 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 Interference
The scheduling of the water drawdown has been especially devastating for the toads, as the spawning period was nearing its natural conclusion. Volunteers had anticipated that the toads would vacate the site in four to six weeks, allowing them to lay their spawn and allowing the young to grow into toadlets before leaving. Had the utility provider postponed the necessary maintenance by this relatively short period, the amphibians would have completed their reproductive cycle and left the reservoir of their own accord, avoiding the catastrophic loss of life 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 departed over four to six weeks
- Spawn would have transformed into toadlets ahead of water removal
- Reservoir usually fills with male toad sounds during breeding
- Volunteers had assisted approximately 1,500 toads getting to the site
Volunteer Efforts and Environmental Effects
Many years of Dedicated Work
The volunteers of Wrexham Toad Patrols have invested considerable resources and commitment into safeguarding the amphibian population for years, operating consistently 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, quadrupling the numbers from the year before as volunteer numbers increased. The dramatic increase demonstrated growing community engagement with conservation efforts in the region.
The rapid emptying of the Nant-y-Ffrith reservoir has effectively negated extensive careful efforts by the volunteers. Ella Thistleton, a fellow member of the monitoring team, expressed the wider consequences of the loss, stressing that the reservoir sustains an whole ecological system separate from the toads themselves. The volunteers’ work were not simply concerned with relocating single creatures; they constituted a comprehensive conservation strategy designed to protect a sensitive ecological network. The shock of the reservoir’s sudden drainage across the Easter period has deeply affected the volunteers, particularly given that their work was progressing well and effectively.
Conservation charity Froglife has documented concerning population drops in common toad populations across the United Kingdom, with research showing a 41 per cent decrease over the previous four decades. Much of this decline originates in the loss of garden ponds in housing 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 serious impact to broader conservation efforts. With suitable spawning grounds becoming ever scarcer, the loss of this vital location 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
Extended Conservation Concerns
The emptying of Nant-y-Ffrith reservoir reveals a significant flaw in Britain’s conservation of amphibians strategy. With toad numbers having plummeted by 41 per cent over four decades, according to research by wildlife charity Froglife, the removal of established breeding sites threatens to accelerate this alarming decline. The investigation revealed the common vanishing of domestic ponds as a primary driver of population decline, suggesting that natural reservoirs have grown increasingly vital for the survival of species. The location in Wrexham constituted one of the handful of reliable breeding grounds in the area, so its unplanned depletion proved particularly damaging to conservation work that have taken years to establish and sustain.
The incident raises important issues about cooperation between water companies and environmental organisations during key reproductive periods. Volunteers emphasised that a delay of merely four to six weeks would have allowed toads to conclude their reproduction, allowing the water company to proceed with essential safety work without severe repercussions. The failure to provide notice or consultation with local conservation groups points to widespread failures in ecological planning frameworks. As Britain encounters increasing demands to safeguard diminishing species numbers, incidents like this emphasise the requirement for improved communication and cooperative planning between infrastructure providers and environmental partners 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 Provider’s Response and Upcoming Initiatives
Hafren Dyfrdwy, the water company responsible for the drainage, has defended its choice by emphasising the essential nature of the safety work carried out at the Nant-y-Ffrith reservoir. A company representative recognised the concerns expressed by the local community and conservation volunteers, noting that the maintenance operations was essential to ensure the reservoir stayed safe for operational purposes both both currently and going forward. The company characterised the reservoir as a crucial water supply supplying the local area, suggesting that infrastructure safety took precedence over other considerations throughout the Easter weekend works.
Despite recognising the ecological importance of the situation, Hafren Dyfrdwy has not yet announced specific measures to reduce the effects on amphibian populations or to align future maintenance work with conservation organisations. The company’s approach has been restricted to short comments justifying the need of the work, without providing information about whether comparable work might be scheduled differently in coming years or whether consultation mechanisms with conservation bodies might be established. This absence of thorough consultation has left conservation volunteers uncertain and concerned about how to prevent comparable problems from occurring during future breeding periods.
Safety Versus Conservation
The incident reveals a fundamental tension between structural preservation and environmental protection in Britain’s aquatic resource management. Whilst reservoir safety work is undoubtedly necessary to safeguard community wellbeing and water supplies, the timing and lack of advance notice created a avoidable tension through better planning. Ecological authorities argue that critical work can be timed to reduce ecological damage, especially if mating periods follow patterns and relatively short-lived, demanding just slight deferrals to avoid severe environmental damage.
- Infrastructure safety requires routine upkeep to safeguard public water supplies
- Breeding seasons are foreseeable and comparatively brief, lasting four to six weeks
- Better collaboration could enable safety initiatives and conservation goals to succeed
