Conservationists in Wrexham fear that over 1,000 toads have perished after a reservoir was suddenly emptied by a water supplier over the Easter weekend. Members of Wrexham Toad Patrols, a voluntary organisation that has devoted months helping amphibians safely cross a busy road to access their spawning site 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 upgrades, but volunteers argue the timing was catastrophic, as the toads were weeks short of 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—four times the number from 2025.
The Mating Period Disruption
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 within 4-6 weeks, enabling them to deposit eggs and allowing the tadpoles to develop into toadlets before departing. Had the water company postponed the necessary maintenance by this relatively short period, the creatures would have completed their reproductive cycle and departed naturally, preventing the catastrophic loss of life 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 migrated in four to six weeks
- Spawn would have developed into toadlets ahead of water removal
- Reservoir typically fills with male toad calls during breeding
- Volunteers had assisted approximately 1,500 toads arriving at the site
Volunteering Initiatives and Environmental Effects
Years of Dedicated Work
The volunteers of Wrexham Toad Patrols have invested considerable time and effort into protecting the amphibian population for years, operating consistently during the mating period between February and May. Operating at two sites—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 approximately 1,500 toads demonstrated impressive results, multiplying four times the numbers from the year before as volunteer numbers increased. The significant growth reflected growing community engagement with conservation efforts in the region.
The sudden drainage of the Nant-y-Ffrith reservoir has effectively negated extensive careful efforts by the volunteers. Ella Thistleton, a fellow member of the monitoring team, outlined the wider consequences of the loss, emphasising that the reservoir maintains an entire ecosystem separate from the toads themselves. The volunteers’ work were not just focused on moving individual animals; they embodied a thorough ecological approach intended to safeguard a delicate biological community. The shock of the reservoir’s abrupt loss across the Easter period has deeply affected the volunteers, particularly given that their work was progressing well and without difficulty.
Conservation charity Froglife has identified troubling decreases in common toad populations across the United Kingdom, with research indicating a 41 per cent decrease over the past four decades. Much of this decline originates in the loss of garden ponds in domestic settings, 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 spawning grounds becoming ever scarcer, the loss of this vital location threatens to accelerate population declines further, compromising years of conservation work across the region.

- Increased fourfold toad numbers supported this year versus 2025
- Ecosystem goes further than toads to newts and frogs
Extended Sustainability Challenges
The emptying of Nant-y-Ffrith reservoir uncovers a significant flaw in Britain’s amphibian conservation strategy. With toad numbers having declined by 41 per cent over 40 years, according to research by conservation charity Froglife, the loss of established breeding sites risks accelerate this troubling descent. The study found the extensive loss of domestic ponds as a leading factor of population collapse, suggesting that reservoir systems have assumed greater significance for species survival. The Wrexham site was one of the limited number of dependable breeding sites in the region, making its unexpected drainage especially harmful to conservation efforts that required years to establish and sustain.
The incident brings to light serious questions about cooperation between water companies and wildlife bodies during vital breeding times. Volunteers stressed that a postponement of just four to six weeks would have enabled toads to conclude their reproduction, allowing the water company to carry out essential safety work without severe repercussions. The lack of advance notice or discussion with local conservation groups suggests systemic failures in ecological planning frameworks. As Britain faces mounting pressure to protect declining wildlife populations, incidents like this underscore the requirement for improved communication and joint planning between infrastructure operators and wildlife organisations to prevent further irreversible damage to endangered 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 essential nature of the safety operations undertaken at the Nant-y-Ffrith reservoir. A company representative recognised the worries raised by the local residents and conservation volunteers, noting that the maintenance work was vital to ensure the reservoir remained safe for operational purposes both both currently and going forward. The company described the reservoir as a vital drinking water supply serving the surrounding region, suggesting that infrastructure safety took precedence over other factors during the Easter weekend works.
Despite recognising the ecological importance of the situation, Hafren Dyfrdwy has still not announced specific measures to reduce the effects on amphibian populations or to coordinate upcoming maintenance activities with conservation organisations. The company’s response has been limited to brief statements defending the necessity of the work, without offering details about whether comparable work might be timed differently in future or whether engagement processes with conservation bodies might be established. This absence of thorough consultation has made conservation volunteers frustrated and uncertain about how to prevent similar incidents from occurring during subsequent breeding seasons.
Safety Versus Conservation
The incident highlights a core conflict between facility upkeep and ecological conservation in Britain’s aquatic resource management. Whilst dam safety operations is undoubtedly necessary to safeguard community wellbeing and water supplies, the scheduling and insufficient warning created a conflict that could have been avoided through improved coordination. Conservation experts argue that critical work can be scheduled to minimise ecological damage, notably when breeding seasons are predictable and limited in length, demanding just slight deferrals to prevent catastrophic ecological consequences.
- Infrastructure safety requires routine upkeep to protect public water supplies
- Reproductive periods are foreseeable and relatively short, running between four and six weeks
- Better collaboration could allow safety initiatives and conservation goals to succeed
