Conservationists in Wrexham worry that over 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 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, expressed shock at the sudden drainage. The Hafren Dyfrdwy water company stated the work was necessary for safety upgrades, but volunteers argue the timing was disastrous, as the toads were weeks short of finishing their spawning period and naturally leaving the site. The incident has devastated the group, which had successfully guided 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 been especially damaging for the toads, as the breeding season was nearing its natural conclusion. Volunteers had anticipated that the toads would leave the area within four to six weeks, allowing them to deposit eggs and allowing the young to grow into toadlets before departing. Had the utility provider postponed the essential maintenance work by this brief timeframe, the amphibians would have finished breeding and left the reservoir of their own accord, avoiding 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 departed in four to six weeks
- Spawn would have matured into toadlets ahead of water removal
- Reservoir typically fills with male toad calls throughout breeding
- Volunteers had assisted nearly 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 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 success in helping approximately 1,500 toads represented a remarkable success, multiplying four times the numbers from the year before as volunteer numbers increased. The significant growth demonstrated increased public involvement with conservation efforts in the region.
The abrupt loss of the Nant-y-Ffrith reservoir has substantially reversed extensive careful efforts by the volunteers. Ella Thistleton, one of the members of the monitoring team, expressed the larger impact of the loss, underlining that the reservoir maintains an complete biological community outside of the toads themselves. The volunteers’ activities were not just focused on transporting individual toads; they constituted a comprehensive conservation strategy intended to safeguard a delicate biological community. The shock of the reservoir’s sudden drainage during the Easter break has deeply affected the volunteers, particularly given that their work had been advancing successfully and without difficulty.
Conservation charity Froglife has recorded alarming declines 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 localised issue but a significant blow to broader conservation efforts. With suitable reproductive sites becoming ever scarcer, the loss of this crucial site threatens to intensify population reductions further, undermining years of conservation work across the region.

- Quadrupled toad numbers supported this year compared to 2025
- Ecosystem encompasses more than toads to frogs and newts
Broader Conservation Concerns
The depletion of Nant-y-Ffrith reservoir reveals a critical vulnerability in Britain’s conservation of amphibians framework. With common toad populations having declined by 41 per cent over four decades, based on findings by conservation charity Froglife, the removal of established breeding sites risks accelerate this alarming decline. The investigation revealed the extensive loss of garden ponds as a main cause of population decline, suggesting that reservoir systems have assumed greater significance for the survival of species. The Wrexham site represented one of the limited number of reliable breeding grounds in the region, making its unexpected drainage especially detrimental to conservation work that required considerable time to set up and develop.
The incident raises important issues about coordination between water companies and conservation groups during critical breeding seasons. Volunteers pointed out that a postponement of just four to six weeks would have enabled toads to conclude their reproduction, enabling the water company to undertake necessary safety measures without catastrophic consequences. The absence of prior notification or discussion with local wildlife bodies points to systemic failures in ecological planning frameworks. As Britain confronts growing pressure to preserve dwindling wildlife, incidents like this highlight the need for enhanced dialogue and cooperative planning between utility companies and environmental partners 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 Company Response and Future Plans
Hafren Dyfrdwy, the water company managing the drainage, has defended 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 residents and conservation volunteers, noting that the maintenance work was vital to ensure the reservoir stayed safe for operational needs both now and in the future. The company characterised the reservoir as a crucial drinking water supply supplying the surrounding region, suggesting that safety of the infrastructure was prioritised above other considerations 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 align future maintenance work with environmental groups. The company’s approach has been limited to brief statements justifying the need of the work, without providing information about whether comparable work might be scheduled differently in future or whether consultation mechanisms with environmental groups might be put in place. This absence of thorough consultation has made conservation volunteers frustrated and uncertain about how to prevent comparable problems from occurring during future breeding periods.
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 clearly essential to ensure public safety and water provision, the scheduling and insufficient warning created a preventable dispute through better planning. Environmental specialists argue that essential maintenance can be scheduled to minimise wildlife impact, particularly when reproduction cycles are foreseeable and relatively short-lived, requiring only modest delays to avoid severe environmental damage.
- System protection requires regular maintenance to protect community water systems
- Breeding seasons are predictable and comparatively brief, running between four and six weeks
- Better collaboration could allow safety initiatives and conservation goals to be achieved
