Hooven Bog, Past, Present, and Future"

 A rare but important win for rare habitat conservation

by Dr. Sarah Spear Cooke, wetland scientist and restoration ecologist

Sitting in the rapidly urbanizing landscape of south-central Snohomish County sits Hooven Bog. A 30+-acre sphagnum bog/fen/emergent wetland complex that is surrounded by mature forest for at least half its periphery. Atypical of most uniform bogs, this wonderful bog/wetland complex displays at least five distinct bog/fen vegetation communities with many bog endemic species.


Hooven remained relatively untouched until about 40 years ago when the first houses were built along the northern shore and a narrow gravel road was constructed along the western third of the emergent habitat. The last few years have been the most damaging to Hooven because the developer who owned it, and the mature forest along the southern shore, began expanding the old gravel road. This caused huge issues with the water chemistry and disturbed much of the understory of the mature forest.


In this program Dr. Cooke will take us on a tour of the bog’s varied habitat types with photos from this summer’s plant inventory. Along the way she will introduce the diverse flora of each habitat type, including the rare and bog-endemic species. She will also discuss weed removal activities to-date and plans for the future.


Dr. Cooke is a long time member of WNPS. She has particular interest in the wetland flora of the Pacific Northwest, which includes working with WNPS and Seattle Audubon in publishing The Field Guide to the Wetland Plants of Western Washington and Northwestern Oregon. She is currently preparing the 2nd edition of this guide.

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.
