Red Data List

Red Data Lists or Books are registers of species whose continued existence is threatened in the wild. They exist at international, national and local levels.

The Essex Red Data List was compiled for English Nature (now Natural England) by P.R. Harvey on behalf of the Essex Field Club, with the input of County Recorders and other county specialists and with an extensive period of consultation. It list is an important compilation of Essex information, helping to inform and better enable biodiversity and planning decisions throughout the county. As an internet resource, it is intended to keep the list up-to-date.

The full list and criteria for inclusion is available on the Essex Field Club's website .
