Outings are open to everyone, not just members. All levels of expertise, from beginners to experienced botanizers, are welcome. Address questions about physical requirements to the leader. It is wise to contact the leader before the trip, in case plans change.


November 13, Wednesday. "Treasure Hunts and Databases Help Rare Plants."  How many rare plant species do we have in the North Coast?  How are they doing?  Is anyone keeping track of them?  How does the CNPS Rare Plant Treasure Hunt Program relate to the California Natural Diversity Database (CNDDB)?  Greg O'Connell, our chapter's co-Rare Plant Chair and an Environmental Scientist with California Department of Fish and Wildlife, will answer these questions and more.  The answers will highlight CNDDB data from the North Coast region.  The goal of CNDDB is to provide the most current information available on the state's most imperiled elements of natural diversity and to provide tools to analyze these data.  Data in CNDDB help drive conservation decisions, aid in the environmental review of projects and land use changes, and provide baseline data helpful in recovering endangered species and for research projects. 

December 11, Wednesday.  7:30-9:00.  Native Plant Show and Tell: North Coast Scholarship Research.  Gabe Goff and Len Mazur will share the results of their 2019 research, funded in part by the North Coast Chapter.  Gabe is a graduate student in the Humboldt State Forestry, Watershed, and Wildland Sciences Program.  His research investigates the effects of conifer encroachment and removal on ecosystem physiology and biodiversity in native Oregon White Oak woodlands.  Len is currently the lead Vegetation Management Technician for Sonoma County Regional Parks, where he is working to establish an early detection network for invasive weeds, monitor post-fire landscapes, and restore rare plant habitats throughout the county.  He received his degree from Humboldt State University in the spring of 2019.  Here he will share the methods and results of his senior capstone project, in which he assessed the health and degree of woody plant encroachment of two Darlingtonia fens in the Mill Creek Addition of Del Norte Coast Redwoods State Park

January 8, 2020.  Wednesday.  7:30 p.m.  "Butterflies of Coastal Humboldt County."  Butterflies decorate the native plants of Humboldt County, and in some cases have relationships with specific hosts. Join us for a three-part presentation celebrating the butterfly diversity in the county.  Local naturalist Bill Rodstrom will present a summary of the new North Coast Chapter's guide to butterflies and host plants, many of which are available in our nursery.  This will be followed by retired Eureka High School science teacher Robert Child's quick guide to butterfly ID using his watercolor art, highlighted in a new poster celebrating the butterflies of coastal Humboldt.  Posters will be available at the talk. Gary Falxa will wrap up the talk with a short discussion on Monarch Butterfly conservation and ecology. Come and get inspired for spring planting to enhance your garden's wildlife!

February 12, Wednesday.  7:30 p.m.  Updated research into gall wasps (Cynipidae) in Northern California.  Tiny, gentle wasps of the family Cynipidae collectively produce galls on roses, thimbleberry, oaks, tan oak, and chinquapin.  During a presentation given six years ago, only cynipids occurring on oaks (Quercus spp.) were covered.  This updated presentation will discuss new findings on the life histories of cynipids on oaks, tan oak (Notholithocarpus), chinquapin (Chrysolepis sp.), roses (Rosa spp.), and thimbleberry (Rubus parviflorus).  Join Dr. John DeMartini, a Humboldt State University Professor emeritus with a passion for regional natural history, for this interesting talk.

May13, Wednesday. 7:30 p.m.  "Botanizing the BLM Lands of the North Coast."  Jennifer Wheeler, botanist for the Bureau of Land Management (BLM) in Arcata, will take us on a virtual journey across BLM lands on the North Coast.  The BLM manages a diverse collection of habitats across Humboldt, Trinity, and Mendocino Counties, including Red Mountain, South Fork Eel, and King Range.  Jennifer will introduce us to a variety of wonderful plants including the newly described Wailaki Lomatium (Lomatium kogholiini) from the Red Mountain Area of Critical Environmental Concern.  We will also visit the Douglas-fir forests of Butte Creek Management Area and the oak woodlands of Lacks Creek and Travis Ranch.
