Over 1,000 Toads Feared Dead After Welsh Reservoir Drained in Breeding Season
Conservationists in north Wales have raised alarms that more than 1,000 toads may have perished after a water company drained a reservoir crucial to the local ecosystem during the peak breeding period. The incident at Nant-y-Ffrith reservoir on the Llandegla moors has left volunteers from Wrexham Toad Patrols feeling shocked, angry, and heartbroken, as they discovered the site emptied over the Easter weekend.
Timing Criticised by Wildlife Advocates
Teri Davies, a representative of the patrol group, highlighted the poor timing of the drainage in a social media post. She questioned why Hafren Dyfrdwy chose to undertake the work at the height of spring, when wildlife heavily depends on these waters for breeding, feeding, and nesting. Davies emphasised that while the need for safety improvements is understood, delaying the project by just a few weeks could have made a significant difference in protecting the declining species.
Wrexham Toad Patrols assist toads returning to the reservoir each breeding season, this year helping 1,500 amphibians cross busy roads to safeguard their populations. Toads are known to return to the same breeding sites annually and do not relocate, making the loss of the reservoir potentially devastating for their survival.
Broader Ecological Impact Beyond Toads
The draining of Nant-y-Ffrith reservoir near Wrexham affects more than just toads. The site is home to various bird species, including the great crested grebe and coot, as well as sedge warblers, reed buntings, lapwings, and curlews that inhabit adjacent streams, fields, and a wooded valley. Davies warned that birds like curlews and lapwings have lost vital breeding and feeding grounds, and the impact will ripple through the entire ecosystem, affecting frogs, newts, insects, and even reported otters.
Water Company Responds to Concerns
Hafren Dyfrdwy, which operates in north-east and mid Wales, stated that the reservoir was drained to carry out essential safety improvements. A spokesperson acknowledged the situation as concerning for the local community and expressed a desire to identify ways to rectify the issue for the future. The company is currently reviewing the events alongside ecologists on site to assess the full extent of the damage.
Long-Term Decline of Common Toad Populations
This incident highlights the broader challenges facing wildlife conservation in the UK. According to the wildlife charity Froglife, common toad populations have declined by 41% over the past 40 years, underscoring the urgency of protecting their habitats. The loss of breeding sites like Nant-y-Ffrith reservoir could exacerbate this trend, making timely and ecologically sensitive management practices critical for preserving biodiversity.
