H9: Limestone Heath

Limestone heath is a rare habitat type and occurs where sand deposits have accumulated on a limestone substrate. Limestone heath usually forms at high level on hills and escarpment slopes the sand having come from further north blown by the wind. The mix of acidic sands and underlying calcareous rocks can produce a strange cocktail of heather and gorse mixed with chalk grassland flora like common milkwort, dropwort and salad burnet.  Limestone heath is not separately classified and often gives the appearance of acid grassland so the appearance of chalk loving plants in amongst the heath species produces a strange effect!
