Conservationists in Wrexham fear that over 1,000 toads have died after a reservoir was unexpectedly drained by a water supplier over the Easter weekend. Members of Wrexham Toad Patrols, a voluntary organisation 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, expressed shock at the sudden drainage. The Hafren Dyfrdwy water company said the work was necessary for safety upgrades, but volunteers argue the timing was disastrous, 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—quadruple the number from 2025.
The Breeding Season Interference
The timing of the water drawdown has been particularly damaging for the toads, as the breeding season was approaching its end. Volunteers had anticipated that the toads would leave the area within four to six weeks, allowing them to lay their spawn and enabling the tadpoles to develop into juvenile toads before departing. Had the water company postponed the necessary maintenance by this brief timeframe, the creatures 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 matured into toadlets ahead of water removal
- Reservoir usually fills with male toad sounds during breeding
- Volunteers had assisted nearly 1,500 toads getting to the site
Volunteer Efforts and Ecological Impact
Years of Consistent Effort
The volunteers of Wrexham Toad Patrols have devoted substantial time and effort into protecting the amphibian population for many years, operating consistently during the mating period 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 achievement of assisting approximately 1,500 toads represented a remarkable success, quadrupling the numbers from the previous year as volunteer numbers swelled. The dramatic increase reflected increased public involvement with environmental protection work in the region.
The abrupt loss of the Nant-y-Ffrith reservoir has effectively negated months of painstaking work by the volunteers. Ella Thistleton, a fellow member of the patrol group, highlighted the wider consequences of the loss, underlining that the reservoir supports an whole ecological system separate from the toads themselves. The volunteers’ activities were not merely about moving individual animals; they constituted a comprehensive conservation strategy intended to safeguard a fragile natural system. The impact of the reservoir’s sudden drainage during the Easter break has profoundly impacted the team, especially considering that their work had been proceeding smoothly and without difficulty.
Conservation charity Froglife has identified troubling decreases in common toad populations across the United Kingdom, with research revealing a 41 per cent decrease over the last 40 years. Much of this decline stems from 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 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 intensify population reductions further, compromising 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
Broader Sustainability Challenges
The depletion of Nant-y-Ffrith reservoir exposes a critical vulnerability in Britain’s conservation of amphibians approach. With common toad populations having declined by 41 per cent over four decades, based on findings by conservation charity Froglife, the disappearance of established breeding sites could accelerate this troubling descent. The study found the common vanishing of garden ponds as a leading factor of population decline, suggesting that reservoir systems have grown increasingly vital for the survival of species. The location in Wrexham constituted one of the limited number of dependable breeding sites in the region, making its unexpected drainage especially harmful to conservation initiatives that required years to establish and develop.
The incident raises serious questions about cooperation between water companies and environmental organisations during key reproductive periods. Volunteers stressed that a delay of merely four to six weeks would have enabled toads to complete their reproductive cycle, permitting the water company to carry out essential safety work without catastrophic consequences. The absence of prior notification or discussion with local conservation groups suggests widespread failures in conservation planning procedures. As Britain confronts growing pressure to preserve dwindling wildlife, incidents like this highlight the need for enhanced dialogue and cooperative planning between infrastructure providers and wildlife organisations to prevent further irreversible damage to vulnerable 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 company managing the drainage, has defended its decision by emphasising the essential nature of the safety operations undertaken at the Nant-y-Ffrith reservoir. A company spokesperson recognised the concerns expressed by the local residents and conservation volunteers, stating that the maintenance work was vital to guarantee the reservoir remained safe for operational purposes both both currently and going forward. The company described the reservoir as a vital drinking water supply supplying the local area, indicating that safety of the infrastructure was prioritised above other considerations during the Easter weekend works.
Despite acknowledging the environmental sensitivity of the situation, Hafren Dyfrdwy has not yet announced specific measures to reduce the effects on frog and toad numbers or to coordinate upcoming maintenance activities with environmental groups. The company’s approach has been limited to brief statements defending the necessity of the work, without providing information about whether similar operations might be timed differently in coming years or whether engagement processes with environmental groups might be put in place. This lack of detailed engagement has left conservation volunteers uncertain and concerned about how to prevent similar incidents from occurring during subsequent breeding seasons.
Safety Versus Conservation
The incident highlights a underlying disagreement between facility upkeep and nature preservation in Britain’s water supply industry. Whilst reservoir safety work is clearly essential to ensure public safety and water resources, the scheduling and insufficient warning created a preventable dispute through better planning. Conservation experts argue that critical work can be scheduled to minimise ecological damage, particularly when reproduction cycles are foreseeable and relatively short-lived, requiring only modest delays to avoid severe environmental damage.
- Infrastructure safety demands routine upkeep to protect public water supplies
- Breeding seasons are foreseeable and comparatively brief, running between four and six weeks
- Better collaboration could enable both safety work and conservation objectives to succeed
