Conservationists in Wrexham worry that more than 1,000 toads have died after a reservoir was suddenly emptied by a water supplier over the Easter weekend. Members of Wrexham Toad Patrols, a voluntary organisation that has spent months helping amphibians securely traverse a busy road to access their spawning site 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 contend the timing was catastrophic, as the toads were weeks short of completing their breeding season and naturally departing the site. The incident has devastated the group, which had successfully guided nearly 1,500 toads to the reservoir this year—four times the number from 2025.
The Breeding Season Interference
The timing of the reservoir drainage has been especially devastating for the toads, as the spawning period was nearing its end. Volunteers had expected that the toads would leave the area in 4-6 weeks, allowing them to deposit eggs and allowing the tadpoles to develop into juvenile toads before departing. Had the water company delayed the necessary maintenance by this brief timeframe, the amphibians would have finished breeding and departed naturally, avoiding the massive death toll that volunteers now fear 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 typically fills with male toad vocalisation throughout breeding
- Volunteers had assisted approximately 1,500 toads arriving at the site
Volunteering Initiatives and Ecological Impact
Many years of Consistent Effort
The volunteers of Wrexham Toad Patrols have invested considerable resources and commitment into protecting the amphibian population for years, working tirelessly during the breeding season between February and May. Operating at a pair of locations—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 nearly 1,500 toads represented a remarkable success, quadrupling the numbers from the previous year 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 substantially reversed extensive careful efforts by the volunteers. Ella Thistleton, another member of the conservation group, outlined the wider consequences of the loss, underlining that the reservoir supports an complete biological community outside of the toads themselves. The volunteers’ efforts were not simply concerned with moving individual animals; they constituted a thorough ecological approach intended to safeguard a delicate biological community. The distress caused by the reservoir’s abrupt loss over the Easter weekend has profoundly impacted the team, particularly given that their work had been advancing successfully and successfully.
Conservation charity Froglife has recorded 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 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 serious impact to broader conservation efforts. With suitable reproductive sites becoming ever scarcer, the loss of this vital location threatens to accelerate population declines further, damaging years of conservation work across the region.

- Quadrupled toad numbers assisted this year versus 2025
- Ecosystem goes further than toads to frogs and newts
Wider Sustainability Challenges
The drainage of Nant-y-Ffrith reservoir uncovers a significant flaw in Britain’s conservation of amphibians framework. With common toad populations 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 alarming decline. The research identified the common vanishing of garden ponds as a main cause of population collapse, suggesting that reservoir systems have assumed greater significance for species survival. The Wrexham site was one of the handful of dependable breeding sites in the area, meaning its sudden emptying was especially detrimental to conservation initiatives that have taken considerable time to set up and nurture.
The incident highlights important issues about coordination between water companies and wildlife bodies during vital breeding times. Volunteers emphasised that a brief delay of four to six weeks would have permitted toads to complete their reproductive cycle, allowing the water company to proceed with critical safety operations without devastating impacts. The lack of advance notice or discussion with local environmental organisations indicates structural deficiencies in environmental planning protocols. As Britain confronts growing pressure to safeguard diminishing species numbers, incidents like this underscore the requirement for improved communication and cooperative planning between infrastructure operators and environmental partners to avoid additional permanent 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 Company Response and Future Plans
Hafren Dyfrdwy, the water company managing the drainage, has defended its decision by highlighting the essential nature of the safety operations carried out at the Nant-y-Ffrith reservoir. A company representative acknowledged the worries expressed by the local residents and conservation volunteers, stating that the maintenance operations was vital to ensure the reservoir remained safe for operational purposes both both currently and going forward. The company characterised the reservoir as a vital drinking water supply supplying the surrounding region, indicating that infrastructure safety took precedence over other factors during the Easter weekend works.
Despite acknowledging the environmental sensitivity of the situation, Hafren Dyfrdwy has not yet announced concrete plans to reduce the effects on frog and toad numbers or to align future maintenance work with conservation organisations. The company’s approach has been restricted to short comments defending the necessity of the work, without providing information about whether comparable work might be scheduled differently in coming years or whether engagement processes with environmental groups might be established. This lack of detailed engagement has made conservation volunteers frustrated and uncertain about how to prevent comparable problems from occurring during future breeding periods.
Safety Versus Conservation
The incident underscores a fundamental tension between structural preservation and nature preservation in Britain’s water supply industry. Whilst reservoir safety work is patently vital to safeguard community wellbeing and water resources, the coordination and poor communication created a avoidable tension through more careful scheduling. Conservation experts argue that necessary upkeep can be scheduled to minimise harm to fauna, particularly when mating periods follow patterns and limited in length, requiring only modest delays to avert major ecological harm.
- System protection demands routine upkeep to protect community water systems
- Reproductive periods are predictable and comparatively brief, running four to six weeks
- Improved coordination could allow both safety work and conservation objectives to be achieved
