The Chalk Grasslands Of Martin Down NNR

Apr 29, 2025

Rolling hills, birds, insects and rare plants

Martin Down NNR, on the Hampshire/Dorset border, comprises 350 hectares of unspoilt calcareous grassland and scrub. This type of landscape was once common in the south, but over the years much of it has been lost to building and unsympathetic farming methods.

Martin Down is home to many beautiful plants such as knapweed, scabious, rare pasqueflowers, and orchids: fragrant, very rare burnt-tip, frog, green-winged, and greater butterfly, as well as a variety of insects, birds, reptiles and mammals.

A selection of photos I’ve taken over the years can be seen below.

Martin Down’s rare pasqueflowers

For the last few years I’ve been photographing the tiny pasqueflowers (Pulsatilla vulgaris) that live at Martin Down, on the Hampshire/Dorset border. In comparison to other sites in the UK, the pasqueflower population at Martin Down is tiny. According to BSBI, these particular pasqueflowers were originally thought to be non-native, but it has been discovered that they are genetically similar to other populations in southern England, so they are likely to be indigenous.

Since Martin Down NNR comprises 350 hectares of chalk grassland, unless you know where to look, it is nigh on impossible to find the handful of pasqueflowers that thrive there. And those who are ‘in the know’ usually keep the location a secret to prevent the theft of a plant that is already struggling to survive in the wild.

Pasqueflowers are getting harder to find because many of the chalk grasslands in southern England have been turned into farms or built on. The plant needs light grazing and open, calcareous grassland like Martin Down to thrive, albeit only a few pasqueflowers grow here.

There are only 17 isolated pasqueflower colonies in the UK, and only three have more than 10,000 individual plants: Therfield Heath, Hertfordshire; Barnsley Warren, Gloucestershire; and Barnack Hills and Holes, Northamptonshire. Once widespread, pasqueflowers are now classed as ‘Vulnerable’ on the Vascular Plant Red Data List for Great Britain.

I always feel privileged to see the Martin Down pasqueflowers; so happy to know they have made it through to another year.
