Central Puget Sound Chapter

   Chapter Information         


to the Central Puget Sound Chapter (CPS) of the Washington Native Plant Society! 
We serve King County and the southern half of Snohomish County, encompassing native forests, alpine areas, wetlands, coastal areas, streams and a booming population.  For numerous ways to discover and protect native plants and their habitats close to home, see below.
Whether your interest is in learning all you can about native plants and botany, taking care of native plant habitats at home and beyond, or meeting others who are equally passionate about native plants, the CPS chapter has many ways for you to meet your goals.  Please explore our website, and do not hesitate to contact any of our board members if you would like to jump in or have questions.


Spring Native Plant Sale and Environmental Fair--
Make Your Yard Habitat-Friendly with Native Plants

Date: Saturday, April 28, 2018
Time: 10am - 4pm
Place: Mercerdale Park, 77th Ave. and 32nd St., Mercer Island, WA   98040

It’s the perfect time of year to add to your native garden, with plants that will invite birds, butterflies and bees to your home environment.

You'll find the largest local selection of beautiful native trees, shrubs, perennials, and ground covers for sale all in one place. These plants, brought together for this one day from regional nurseries and our own nursery's propagation efforts, are ideal for Western Washington gardens and vitally important for our birds and pollinators. Choose as many plants as you like – our little red wagons will help you transport them to your car.

Native plant experts will dispense gardening advice and answer your questions about native plants.  And be sure to visit the Environmental Fair. Our past environmental fair participants have included organizations such as the National Wildlife Federation, Bats Northwest, King County Noxious Weeds, Audubon and more. We have also had Flora and Fauna Books selling native plant and nature books. 

There is plenty of free parking and Mercerdale Park has open picnic areas and a children’s play area. 

Proceeds from this event benefit WNPS-CPS and its education programs. For more information, please contact Yen Flanagin at yen.flanagin@yahoo.comor the Washington Native Plant Society at 206-527-321 or visit our website at





A Four Dimensional Mountain:
Plant Associations in our Shrub-Steppe
Mike Marsh
Thursday, March 1
The Mountaineers Program Center Goodman Room, Seattle
7:00 pm

In eastern Washington, the Washington Department of Fish and Wildlife manages shrub-steppe lands (Wildlife Areas) that, under lease agreements with private ranchers, are grazed by livestock in late spring. Some of these lands are winter habitat for elk herds. We wondered how different the vegetation is on those lands without livestock grazing from those with livestock grazing. Two wildlife areas in eastern Kittitas County, the Quilomene and Whiskey Dick, seemed to offer an opportunity to find out. Dr. Marsh will share his findings from this study which was supported in part by the Washington Native Plant Society.

Mike Marsh and his wife, Jane, have been members of the Central Puget Sound Chapter of the WNPS since 1996. During that time, he has made numerous and wide ranging contributions to our organization, from serving as conservation chair to conducting research studies. Two enduring themes of his life have been a passion for the natural world and his geographic mobility. He was born in Pt. Limon, Costa Rica and  has lived in Panama, Honduras, Nicaragua, and Australia.  In the United States, he has lived in the states of Arizona, California, Michigan, and Kentucky.  Since 1985, he has resided in Washington. He completed his PhD in Zoology at U.C. Berkeley in 1961. Since that time, he has held multiple research and teaching positions.  He retired from his position at the Environmental Protection Agency in 1999, where he had been conducting research and developing educational materials.

Program produced by Sharon Baker and Shelley Evans
