Hertfordshire Natural History Society’s volunteers have been monitoring local wildlife since 1875.

The valuable information they collect on birds, mammals, insects, plants and other species groups helps track how the natural world is changing around us.

Wild About Hertfordshire – Our 150th anniversary at St Albans Museum (21 March - 6 July 2025) –  looks back at 150 years of sharing and extending that knowledge. It celebrates our county’s wildlife and habitats and shows how the work of dedicated volunteers is helping protect them for the future in uncertain times.
