Therfield Heath seemed like the ideal location for a walk on Easter Monday afternoon. It lies looking northwards across the flatlands of Cambridgeshire, the ancient market town of Royston sitting to its north-east and is a good birdwatching spot, hosting a large numbers of grassland birds and accompanying raptors . However it is the chalk geology and steep sided grassland escarpments that provide a rather special treat around Easter time.
Tucked away, where the Hertfordshire Way touches the golf course on Church Hill, delicate Pasque Flowers bloom from the short cropped grass in their hundreds and in some years thousands, interspersed with yolk yellow cowslips. That they grow in such numbers here points to the rarity and complexity of the habitat, making it one of less than twenty known locations for the plant in the whole of the UK, as Fred Rumsey, Botanist at the Natural History Museum explains in this short film.
