Hertfordshire County Recorders

We have a network of volunteer recorders, who are experts on specific groups of species and collate and co-ordinate records and are willing to assist with identification of the more unusual species. Their contact details are below.

Unfortunately we do not currently have volunteers to cover the following groups: bugs (terrestrial), cockroaches, earwigs, grasshoppers and crickets, molluscs, mosses and liverworts.
If you are interested and willing to help please get in touch with Ronni Edmonds-Brown
