2.3.1.1 Native populations<br />

Since its discovery near to Oxford in 1551 (Druce, 1886) <strong>Pulsatilla</strong> <strong>vulgaris</strong> has been recorded<br />

from around 130 sites in 19 English vice-counties (Table 2) but is now confined to 18 sites in<br />

just ten vice-counties (Table 3). Former strongholds include the Cretaceous chalk downland<br />

and ancient earthworks of Bedfordshire, Berkshire, Buckinghamshire, Cambridgeshire,<br />

Hertfordshire and Oxfordshire and the Jurassic limestone grasslands of Gloucestershire,<br />

Northamptonshire and Lincolnshire (Fig. 3). It was also formerly widespread in Magnesian<br />

limestone grasslands in northern England, extending as far north as Piercebridge in County<br />

Durham (Baker, 1906) but it is now restricted to a single site near to Wakefield (Abbott,<br />

2005). Small clusters of populations also occurred in North Essex, Leicestershire, West Norfolk<br />

and West Suffolk but it has not been seen in any of these counties since 1888, 1992, 1914 and<br />

1978 respectively (Table 4).<br />
