From Wildlife Extra:
Rare and iconic snake’s-head fritillary blooming in Oxfordshire
April 2007. A little known site in the heart of Oxford is home to a massive population of a rare but iconic wild flower which used to be abundant in Britain – the snake’s-head fritillary.
This petite, purple and white flower carpets the Berks, Bucks & Oxon Wildlife Trust’s nature reserve at Iffley Meadows during April and the beginning of May.
To check the status of the flowers, every year Trust staff and volunteers count the plants on site.
Looking like a scene from a crime scene drama, they slowly inch along in line, counting every flower they see. The results are now in for this year’s survey and we can now confirm the good news that there are over 42,000 plants on site this year!
April 2011: Oxfordshire’s iconic wild flower, the snake’s-head fritillary, is more abundant than ever before in the county’s meadows. More than 76,400 plants were counted in this year’s survey on Iffley Meadows nature reserve – the highest total recorded since records began in 1981: here.
