We promote the study and recording of wildlife in Hertfordshire and encourage a wider interest in natural history including the conservation of wildlife, habitats and geological features.

Our members share an interest in nature and observing and studying wildlife. We get real value from your observations by co-ordinating and compiling everyone’s records to build up a comprehensive picture of the state of wildlife in the county. This helps us understand how it is changing over time in response to the pressures of modern life and climate change.

Photos of Hertfordshire wildlife can be found in the photo galleries here and in the Flora group and Bird Club websites.

We have been studying and documenting the natural history of our county for over 130 years. We endeavour to cover all branches of natural history relevant to Hertfordshire.

We encourage wildlife recording. You can submit your records on line for birds, for mammals, amphibians, reptiles and dragonflies and for plants, view the latest sightings and sightings archive (from 2010).

We have a network of 26 county wildlife recorders who are experts in their field and collate the records for specific groups, such as birds, mammals, insects and flowers. Their reports are published in our annual journals, The Hertfordshire Naturalist and The Hertfordshire Bird ReportLearn more…
We also publish books on specific subjects,

We have specialist groups that focus on birds, moths and flora and close links with other local groups such as Butterfly Conservation.

Membership is open to anyone, whether or not you live in the county.
