Hewitt's Chalk Bank

A chalk downland site with a good plant community.

A chalk downland site, there is a large chalk mound on this reserve, formed after the excavation of a railway tunnel. The mound supports a good plant community, including wild thyme, pyramidal and bee orchid as well as soapwort, wild parsnip and common milkwort. The southern part of the site is covered by grassland with scrub and is very popular with birds. Species seen include whitethroat, linnet, greenfinch and chaffinch.

The site was once a refuse tip and the clay that has been used to cap it has led to a variety of plants growing in pathces within the grassland area. Grass vetchling and dark mullein are amongst the more unusual flora.
