To keep everyone safe, and to help to prevent the spread of Coronavirus, the Cambrian’s 2021 Programme will be conducted via the internet by ZOOM, at least for the beginning of the year. This is regrettable, and we apologise to those of you who cannot access the internet, but is the best we can arrange in the present circumstances. An Autumn Programme will be published later, when hopefully we can meet as normal.

Maryann Williams, our Chairman, will send out the link for each Zoom meeting to all members a few days before the date. Non-members should contact Maryann if they also wish to join a meeting – please do not pass the link on directly to others. For this or any queries the contact is:

All evening will meetings start at 7:30pm. Please disable your microphone while the talk is in progress, and re-enable it at question-time.

Field Trips will be publicised via the Bulletin, and Facebook For field visits you must register with the leader beforehand. Social distancing rules will apply.
