Membership runs from January 1st through December 31st. |
Your membership contribution supports our regular programs, including monthly presentations, field trips, and educational outreach.
If you would like to make an additional contribution in direct support of our general programs, please visit the Donate page as we currently cannot add a donation to the membership renewals. If you would like to combine the two you can send a check to
ASCO at PO Box 8146 Bend, Oregon 97708-8146.
