Talks and other activities covering all aspects of natural history, including botany, conservation, ecology, entomology, geology, palaeontology, zoology etc. See web page https://www.cnhs.org.uk/ for full details, and additional activities not listed here (we have excursions, field-trips, etc. in summer instead of talks).

All talks this Spring (2026) are in-person starting at 6.45pm prompt, free to all, and will be relayed live via Zoom.

Talks may be recorded and if so, CNHS members who cannot join the event (or who wish to watch it again) will be sent a link to allow them to view it at their leisure.

To receive the login for Zoom events, email cnhs_mailings-join@cnhs.org.uk and follow the instructions you are sent to be added to the list.

Your video and audio will be off when you join in order to give maximum bandwidth to the speaker. At the end of the talk chat will be enabled to ask questions, or you can raise your virtual hand.
