botany, ecology, field studies, and natural history.

The Pacific Northwest supports one of the greatest diversities of bryophytes- mosses, hornworts and liverworts - in the world. These terrestrial, epiphytic, and rock-dwelling taxa perform critical ecological roles in our forests, prairies, and urban areas. They intercept and retain nutrients and moisture from rainwater and mist, provide habitat and nesting material for invertebrates and vertebrates, and are important bioindicators of ecosystem health and global climate change.

This program focuses on bryophyte taxonomy, ecology and biology. Field trips will emphasize the recognition of ecological life forms and morphological growth forms of bryophytes as well as proper collection methods. Lab activities will involve identifying collected specimens using dichotomous keys and developing proficiency in techniques for the identification of mosses such as dissection, slide-making techniques and use of compound and dissecting microscopes. Lectures will focus on readings from a bryophyte ecology textbook as well as current topics in bryophyte biology and taxonomy. Seminar readings will include a variety of essays, books and scientific papers on the economic, medicinal and aesthetic value of bryophytes. Students will conduct quarter-long group research, which may include herbaria-based taxonomic studies, moss propagation experiments, field-based floristic studies or installation of moss rooftop teaching garden on campus. Students will also contribute to the ongoing curation and databasing of the Evergreen Herbarium Bryophyte Collection.
