About us
This is a group for anyone interested in supporting the Washington Native Plant Society (WNPS). Our mission is to promote the appreciation and conservation of Washington's native plants and their habitats through study, education and advocacy.
The Central Puget Sound Chapter (CPS) hosts regular monthly membership meetings 7 times a year in Seattle and 4 times a year in Bellevue. Following a brief business discussion and announcements, each meeting features a guest speaker who is an expert on a native plant topic such as native plants found on WA hikes, the impact of climate change and wildfires on native plants, and landscaping with native plants. The Seattle meetings also have a plant identification workshop prior to the start of the meeting.
The CPS Chapter also sponsors a Native Plant Steward training program, which provides 100 hours of free instruction on native plants and environmental stewardship in exchange for a commitment of 100 hours of volunteer work. The organization also has 2 native plant sales a year, where you can find both common and rare species of plants.

Native Bees and Why They Disappear In September
The Mountaineers, 7700 Sand Point Way Northeast, Seattle, WA, USWhere are Our Bees from October to March? Washington is home to MANY species of bees. But we don't see them after September--where are they? In this talk, biology professor Steven Clark will share the very different (from humans) and very interesting life of our native bees. In addition to talking about where bees are, this talk will address bee stings, why most bees don't live in hives and many other fascinating traits of native bees.
Steven Clark is a professor emeritus of biology at Clark College and currently manages Clark’s Bee Campus. Throughout his career, he shared his passion for teaching to students from kindergarten through college. He has degrees in psychology, religion, Deaf education and environmental science. Steven researched the endangered western pond turtle in the Columbia Gorge. Since 2010, he has participated in research led by preeminent pika scientist, Dr. Erik Beever, and helps lead Oregon Zoo’s Cascade Pika Watch. Steven is Vice President of the Washington Native Plant Society and he loves his volunteer work with University of Washington Rare Plant Care. For Oregon Fish and Wildlife, he and his wife, Cherie Kearney, survey sage grouse leks each spring. Left with free time he can be found running on a steep, wooded trail with his dog, Phoebe.
This program is in person in the Cascade Room at the Mountaineers (7700 Sand Point Way NE, Seattle) & also will be live streamed via Zoom at 7:00 PM. It will be recorded for later viewing.
