Conservationists in Wrexham fear that more than 1,000 toads have perished 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 helping amphibians 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 stated the work was essential for safety improvements, but volunteers contend the timing was disastrous, as the toads were weeks short of finishing their spawning period 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 reservoir drainage has been particularly damaging for the toad population, as the spawning period was nearing its end. Volunteers had anticipated that the toads would leave the area in 4-6 weeks, allowing them to lay their spawn and allowing the young to grow into juvenile toads before departing. Had the water company postponed the necessary maintenance by this brief timeframe, the amphibians would have finished breeding and left the reservoir naturally, avoiding 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 migrated over four to six weeks
- Spawn would have matured into toadlets ahead of water removal
- Reservoir usually fills with male toad sounds in the breeding season
- Volunteers had supported around 1,500 toads getting to the site
Volunteer Efforts and Environmental Effects
Years of Consistent Effort
The volunteers of Wrexham Toad Patrols have devoted substantial time and effort into protecting the amphibian population for many years, working tirelessly 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, multiplying four times the numbers from the year before as volunteer numbers swelled. The dramatic increase reflected growing community engagement with conservation efforts in the region.
The sudden drainage of the Nant-y-Ffrith reservoir has substantially reversed extensive careful efforts by the volunteers. Ella Thistleton, one of the members of the conservation group, expressed the wider consequences of the loss, underlining that the reservoir maintains an whole ecological system outside of the toads themselves. The volunteers’ work were not just focused on transporting individual toads; they embodied a complete protection plan intended to safeguard a fragile natural system. The shock of the reservoir’s abrupt loss across the Easter period has deeply affected the volunteers, particularly given that their work had been proceeding smoothly and without difficulty.
Conservation charity Froglife has identified alarming declines in common toad populations across the United Kingdom, with research indicating a 41 per cent decrease over the last 40 years. Much of this decline results from the loss of garden ponds in residential 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 significant blow to broader conservation efforts. With suitable spawning grounds becoming ever scarcer, the loss of this essential area threatens to accelerate population declines further, damaging years of conservation work across the region.

- Increased fourfold toad numbers supported this year compared to 2025
- Ecosystem extends beyond toads to newts and frogs
Extended Sustainability Challenges
The drainage of Nant-y-Ffrith reservoir exposes a critical vulnerability in Britain’s conservation of amphibians strategy. With common toad populations having declined by 41 per cent over 40 years, according to research by wildlife charity Froglife, the disappearance of breeding grounds risks accelerate this alarming decline. The research identified the widespread disappearance of garden ponds as a leading factor of population collapse, indicating that natural reservoirs have grown increasingly vital for the survival of species. The Wrexham site constituted one of the handful of reliable breeding grounds in the area, making its unexpected drainage particularly damaging to conservation initiatives that required considerable time to set up and sustain.
The incident brings to light serious questions about coordination between water companies and conservation groups during vital breeding times. Volunteers pointed out that a postponement of just four to six weeks would have allowed toads to conclude their reproduction, allowing the water company to undertake necessary safety measures without severe repercussions. The failure to provide notice or discussion with local wildlife bodies indicates widespread failures in conservation planning procedures. As Britain encounters increasing demands to protect declining wildlife populations, incidents like this emphasise the need for enhanced dialogue and cooperative planning between infrastructure providers and conservation stakeholders to prevent further irreversible damage 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 Supplier’s Response and Forward Strategy
Hafren Dyfrdwy, the water company responsible for the drainage, has justified its choice by highlighting the essential nature of the safety operations undertaken at the Nant-y-Ffrith reservoir. A company spokesperson recognised the concerns raised by the local community and conservation volunteers, noting that the maintenance work was essential to guarantee the reservoir stayed safe for operational needs both both currently and going forward. The company described the reservoir as a crucial water supply serving the surrounding region, suggesting that safety of the infrastructure took precedence over other considerations throughout the Easter weekend works.
Despite recognising the ecological importance of the situation, Hafren Dyfrdwy has still not announced concrete plans 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 short comments defending the necessity of the work, without providing information about whether similar operations might be scheduled differently in coming years or whether engagement processes with conservation bodies might be established. This absence of thorough consultation has made conservation volunteers uncertain and concerned about how to prevent comparable problems from occurring during subsequent breeding seasons.
Safety Versus Conservation
The incident highlights a fundamental tension between facility upkeep and ecological conservation in Britain’s aquatic resource management. Whilst reservoir safety work is undoubtedly necessary to protect public health and water supplies, the timing and lack of advance notice created a avoidable tension through more careful scheduling. Conservation experts argue that necessary upkeep can be scheduled to minimise ecological damage, notably when mating periods follow patterns and brief in duration, needing merely minor postponements to prevent catastrophic ecological consequences.
- System protection requires routine upkeep to protect public water supplies
- Breeding seasons are foreseeable and relatively short, running between four and six weeks
- Better collaboration could allow safety initiatives and conservation goals to succeed
