Cambridge Natural History Society CNHS is open to everyone interested in all aspects of the natural world. We organise talks, field visits and other natural history events. Join at any meeting.

The Society is open to everyone interested in Natural History - including zoology, botany, ecology, entomology, palaeontology, mycology, conservation, the environment and more. Talks cover a variety of topics and there are exhibitions, excursions, field studies - an opportunity to learn identification skills, and an annual dinner. Joining the Society gives you opportunities to meet people with shared interests and access to local experts. Members receive a programme card and newsletter three times a year and a copy of the annual excursion report. See www.cnhs.org.uk for more info & links to other organisations.
