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.
February 25, Saturday. Freshwater Lagoon Day Hike. In the string of lagoons along the coast north of Humboldt Bay Freshwater Lagoon is the one where Highway 101 is right on the spit between the lagoon and the ocean, a dramatic, straight stretch. The road was not always there. Old State Highway still traverses the slope east (inland) of the lagoon for roughly 3 miles, accessing a few weekend houses. We will do a car shuttle and walk this very lightly traveled road, through Red Alder forest, watching for Red-flowering Currant blooming, and hoping for the red-flowered trillium that likes this habitat, Giant Purple Wakerobin (Trillium kurabayashii). We might have time to walk along the lagoon, looking at wetland plants, or the beach, looking at sand plants. Meet at 9:00 a.m. at Pacific Union School (3001 Janes Rd., Arcata) or arrange another place. Dress for the weather; bring lunch and water. Return late afternoon. It helps to know you are coming: Carol 822-2015.
March 8, Wednesday. 7:30 p.m. “Tall Tree Physiology: Downsides to Being Tall and How Trees Compensate” with Dr. Lucy Kerhoulas of the Forestry Department at Humboldt State University. North Coast residents are personally aware that trees can grow to be really tall. They might be less aware of the complications involved with being a tall tree. Lucy will explain some basics of tall tree physiology and explore some of the adaptations local trees use to take advantage of water sources in their crowns. A number of tree species in the redwood forest produce aboveground roots and support a variety of epiphytes (plants growing on other plants without extracting nutrients from them). Examples include Bigleaf Maple, Vine Maple, Red Alder, Black Cottonwood, Sitka Spruce, and Redwood. As epiphyte mats are one potential local water source in tall tree crowns, this talk will introduce you to the rich community of liverworts, mosses, lichens, and ferns that live on tree branches high above the forest floor.
March 26, Sunday. Redwood Creek Day Hike. Masses of Giant Purple Wakerobin (Trillium kurabayashii) should be waiting for us about `1.5 miles up the Redwood Creek Trail in Redwood National Park. (Trailhead at the bottom of Bald Hills Rd. just north of Orick) The yellow variant of this deep red trillium occurs here, providing fodder for speculation on trillium taxonomy. The riparian and forest edge vegetation will provide early spring fun: Hazelnut in full bloom, several gooseberries, Skunk Cabbage, and possibly early clues of the rare Cardamine angulata. Meet at 8:30 a.m. at Pacific Union School (3001 Janes Rd., Arcata) or arrange another place. Dress for the weather; bring lunch and water. Return late afternoon.

April 12, Wednesday. 7:30 p.m. “All in the Family—Ericaceae” with Bruce Palmer.
April 15, Saturday. Field trip. Destination to be decided.
April 22, Saturday. 12:30-3:30 p.m. Native Plants in Gardens and Forest. Join Carol Ralph, Pete Haggard, and Anna Bernard for a walk from the Arcata Community Center to Arcata Community Forest and back to see native plants in public and private landscapes and in a redwood forest. We will identify a range of native plants and invasive plants, see wildlife in a native plant garden, and think about how to mimic wild habitats in the confines of gardens. Hopefully, trillium will be blooming in the forest. The walk is about 3 miles on sidewalks and good paths, with about 250 ft. elevation gain. Call 826-7050 to register for this free trip sponsored by California Native Plant Society at Godwit Days, or register for Godwit Days at www.godwitdays.org
May 6-7, Saturday-Sunday. Spring Wildflower Show and Native Plant Sale - at the Jefferson Community Center, 100 B St., Eureka. NOTE NEW LOCATION!! Show is also open Friday, May 5, 1-4 p.m. Note special Art Workshop (aka Art Night) Friday, May 5, 7-9 p.m.
May 10, Wednesday. 7:30 p.m. Evening program-- Rob Fernau
September 13, Wednesday. 7:30 p.m. “The Future of Plant Diversity in a Warmer, Drier West” with Dr. Susan Harrison, Professor in the Department of Environmental Science and Policy at University of California, Davis. Years of research on plots in Lake County, California (at the McLaughlin Natural Reserve) and in southern Oregon have provided clear snapshots of how decreases in winter moisture and increased periods of warmer temperatures are affecting native plant communities. Even within the adaptive plant communities in serpentinite environments, long thought to be less susceptible, climate change is impacting germination and growth patterns. Hear about the findings of UC Davis research teams and what we can expect in plant diversity trends within our bioregion.
