1976 (and other hot summers) …

How times have changed …


The prolonged spell of extremely hot weather in 1976, from mid June to the end of August, including fifteen consecutive days where a maximum temperature of 32°C or more was recorded somewhere in the UK, was one of the most protracted heatwaves within living memory. Below average rainfall was notable from May 1975 through to August 1976 resulting in one of the most significant droughts on record.

Apart from the unbearable temperature, the one thing I will always remember from the summer of 1976, in addition to sitting my final exams at school, was the abundance of Silver-washed Fritillary (Argynnis paphia) in Worth Forest, my local Sussex woodland. Pearl-bordered Fritillary (Boloria euphrosyne) and Small Pearl-bordered Fritillary (B. selene) were also abundant to the point where we took them for granted; after all they would always be there - or so we thought. A. paphia is fortunately still present in many Sussex woodlands but our smaller woodland fritillaries are sadly now absent from most of their former haunts. B. selene, which became extinct in Sussex in 2013, is now the subject of a reintroduction programme to its former stronghold.

A warning to value what we have and not take things for granted.
