We have been studying and documenting the natural history of our county for 145 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). Learn more about our objectives.
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 Report. 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.
The HNHS 1875 Awards for outstanding Hertfordshire naturalists and individuals making outstanding contributions to natural history in Hertfordshire are presented at the autumn meeting each year.
The Society depends on voluntary donations and annual subscriptions from members all of which are devoted entirely to carrying out our work, as all officers are honorary.
Safeguarding: We offer family membership and welcome children under 16 to our activities provided they are supervised by a parent or responsible adult at all times. We encourage members to read our policy on safeguarding children, young people under 18 and vulnerable adults, which is reviewed annually.
