May 7th Program Meeting

Lichens: More Than Meets the Eye

with Richard Droker, naturalist andphotographer,  and Dr. Katherine Glew, UW Herbarium, Associate Curator of Lichens

Often overlooked, lichens are diverse, fascinating, beautiful, and also more important than you might think. Individual lichens include representatives of two and sometimes three of life's kingdoms. As dual and treble "organisms" they resort to curious methods of reproduction. Disparate substrates as granites and limestones, hardwoods and conifers, biotic soil crusts and abandoned cars play host to unique lichen communities. They occur in such diverse habitats as rainforest, desert, isolated mountain summits and the intertidal zone. The presentation will be an illustrated overview of the biology of lichens as well as their relationships with plants and wildlife and people.

Richard Droker is a Seattle based naturalist, specializing in geology, ornithology and more recently lichenology. Photography is a key element of his diverse pursuits.  Katherine Glew is a lichenologist with a PhD in botany. She has studied lichens for over 40 years in forest, alpine and island ecosystems.

Plant Identification Workshop

The Central Puget Sound Chapter offers regular plant identification workshops to help members improve plant ID skills.  While the Workshop is oriented primarily toward beginners, anyone who wants to work on improving keying skills or their familiarity with the northwest flora is welcome.  Our main objectives are practice with technical identification keys, familiarity with plant families, and recognition of common northwest species.  No prior experience is necessary; the only requirements are interest in the topic, patience with beginners if you are an old hand, and patience with old hands if you are a beginner.  If you have them, bring a hand lens and a copy of Hitchcock or another favorite plant book.  You are encouraged to bring unknown plants for identification. We will have plenty of material and tools if you come empty handed.  CPS botanists will be the instructors.
