Welcome to the website of the Hertfordshire Natural History Society

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 coordinating 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.

​Clytiomya continua, a rare parasitic fly, was photographed by Simon Knott at Kings Meads on 21 June 2016. Simon says this is only the second record for UK, it has previously been found in an old sand pit in north Essex (Plant & Smith 1997). It is a phasiine parasitoid of Heteroptera, such as the shieldbug Eurydema oleracea (the brassica bug).

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).  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.
