Instructor: Gary Perlmutter Scheduling Details: July 18, 20, 22, 25, & 27 Description: This seminar will introduce participants to the learning about lichens growing in the treetops, where habitats and growing conditions are very different than at or near ground level. This seminar will focus on the identification, biology, ecology of the flora of canopy lichens by studying newly fallen trees and fallen branches and twigs. Participants will learn terminology that describes characters of lichens and their lifestyles and how these characters are used to identify lichens. Participants will learn how to collect and prepare specimens so they can build a starter collection of their own. Identification techniques of chemical spot testing and microscopy will also be covered. Ecological topics such as lichen community succession and pollution sensitivity will also be discussed. Required materials: A hand lens or similar magnifier with 10X magnification or higher (these can be purchased online or at a local hobby store for as little as $6.99).
