Introduction to Tree Identification  FULL - REGISTER FOR WAITLIST ONLINE
Friday, October 10 (9 am-3 pm)
Leader  Cris Fleming
Members $30; nonmembers $42
Fall is a great time to learn to identify our local trees and shrubs. With brilliant leaves highlighting the twigs, new buds already formed, and many fruits hanging on, there are lots of distinguishing features that help sort out the various species. This all-day program at our Woodend Sanctuary will begin indoors with a look at some techniques of tree identification. coupled with  practice using a simple key. We’ll then move outdoors to use our new skills to identify many of the trees growing on the grounds. Both beginners and those who want to brush up on their ID skills are welcome. Register online.

Window into the World of Fungi
Thursday, October 16 (7:30-9:30 pm)
Saturday, October 18 (9 am-1 pm)
Leader  Tovi Lehmann
Members $42; nonmembers $58
Lecture only $20/$28
Rooted, yet not plants, heterotrophs, but not animals (growing in fairy rings, yet not even fairies), fungi are members of another kingdom. Mostly hidden under the surface, fungi have evolved their own solutions to life’s persistent problems. Gaining the recognition for their pivotal role in shaping the living world, they now reshape fundamental perceptions of biologists. In this workshop, we will explore the natural history and ecology of our local fungal neighbors, rather than focus on the edibility of particular species of mushrooms. Our field trip will visit a close-in natural area chosen by the leader, based on his scouting closer to the program. Register online.
