Fears are growing that more than 1,000 toads may have died after a reservoir in north Wales was drained during peak breeding season, prompting concern among conservation groups over the impact on local wildlife.
The site at Nant-y-Ffrith near Wrexham, a key breeding ground for amphibians, was emptied over the Easter weekend by water company Hafren Dyfrdwy just weeks before toads were expected to leave the area.
