From email announcement:

Richmond Tree Steward classes will begin again in January with a 10 week course that is packed with information and delivered by excellent speakers. Our hope is that the room is filled with citizens who want to join our efforts to help care for the urban forest and be a community resource. Since class size is limited preference will be given to those who wish to become Certified Tree Stewards and volunteer with our organization.

According to the site, the deadline to apply is November 22.
