Hill End Pit
A small chalk pit, noted for its fossils, surrounded by chalk grassland and scrub.
Hill End Pit is nationally renowned for its fine fossils which make this one of the Trust's most important geological reserves. It is also of interest for its small area of chalk grassland and scrub. Species to be found include vipers bugloss, cowslip, mullein and marjoram.
The reserve contains the biggest colony of the snail 'Azeca goodalli' known in the county. Frequent butterflies include the common blue, orange-tip and gatekeeper. Many species of birds and mammals flourish on the site. Tits are numerous so too are many finches. Regular warblers include chiffchaff, willow warbler, whitethroat, lesser whitethroat, garden warbler and blackcap. All three species of British woodpecker frequent the area.
The Trust has a legal agreement with North Hertfordshire District Council and Hertfordshire County Council to manage the site.
