Tadpoles In Cornwall - In November (Though Early Record Still Stands At October, 2005)
Frogspawn has been found in Cornwall four months before it is supposed to appear, according to a report. The discovery – the earliest sighting for nearly 10 years – was made by a National Trust ranger, Rachel Holder, on the North Predannack Downs nature reserve on the Lizard.
She told The Guardian: “This year I first saw frogspawn on 21 November, which is early, but not unheard of in a Cornish context. “The gamble of getting ahead in the breeding game must be worth taking, and the risk of a severe cold snap which could freeze the spawn is worth braving.”
Frogspawn was seen on 26 October in 2005 – the earliest recorded date – but usually appears in March.
Dr Kate Lewthwaite, who organises the Woodland Trust’s Nature’s Calendar survey, told the paper: “Although spring is generally arriving earlier, to receive a frogspawn sighting before winter has properly begun is highly unusual.
