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. It helps to know you are coming: Carol 822-2015.

April 12, Wednesday. 7:30 p.m. “All in the Family—Ericaceae”. From a world view to our local species, biologist, natural historian, professor, rhododendron student and gardener Bruce Palmer will give a sweeping, fascinating, and well-illustrated view of the heath family. Besides showy rhododendrons, azaleas, and heathers, this family includes delicious berries, like huckleberries, the diverse manzanitas, and some curious, non-green herbaceous species, like Indian Pipe. Bruce will also detail what we mean by plant families, what it means to be a member of the family Ericaceae, why some members of the family evolved where they are, and how their ancestors got there. At the Six Rivers Masonic Lodge, 251 Bayside Rd., Arcata. Refreshments at 7:00 p.m.; program at 7:30 p.m.

April 15, Saturday. Humboldt Redwoods Day Hike. Slinkpods will be past but other forest floor treats will be beginning to bloom: Western Trillium, Redwood Violets, Candyflowers, California Milkmaids, Pacific Starflower. We will hike two (or maybe three) short trails along the Avenue of the Giants: the Dry Creek Trail (2 miles if we do a shuttle), the Hidden Springs Beach Trail (1.1 miles), and some other if there's time. These trails feature plant diversity, not the biggest redwoods. We should see two species of inside-out-flower, two of fairy bells, three of violet, and at least eight of ferns. Dress for the weather; bring lunch and water. Meet at 9 a.m. at Pacific Union School (3001 Janes Rd., Arcata), or 9:30 a.m. at the McDonald's end of the Bayshore Mall parking lot. Return late afternoon. It helps to know you're coming; phone Carol 707-822-2015.

April 21, Friday, Earth Day. 10 a.m. Hippo Rock for Broom and Wildflowers. Tanya Chapple of Mid-Klamath Watershed Council will lead a broom pull at 10 a.m., followed by a plant walk at 1 p.m. at this easy trail near Orleans.

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

April 29, Saturday. 10:00 a.m.-12 noon. Ferns by the Dunes, a plant walk. In two hours, in a quarter-acre of the Lanphere Dunes Unit of the Humboldt Bay National Wildlife Refuge, naturalist Carol Ralph will introduce eight species of our common ferns and talk about some of the amazing aspects of fern life. Bring a hand lens if you have one, and be prepared for mosquitoes. Meet at 10 a.m. at Pacific Union School, 3001 Janes Rd, Arcata, and carpool to the protected site. Co-sponsored by Friends of the Dunes. Please reserve your space by contacting Friends of the Dunes at 707-444-1397 or This e-mail address is being protected from spambots.

May 10, Wednesday. 7:30 p.m. "The Marble Mountains: Butterflies and Botany." Situated in the heart of the Klamath Bioregion, the Marble Mountain Wilderness has captured the imagination of ecologists for years. Dr. Rob Fernau has been conducting ecological research in the Marbles for 32 years. His work includes sampling butterflies and the plant communities with which they are associated, including ongoing research on climate change and geoecology. In this photo-filled presentation he will share his knowledge and enthusiasm for his favorite place in the world. He looks forward to involving botanists and photographers in field work this spring and summer.

May 20, Saturday. South Fork Trinity River Day Hike with optional overnight. The South Fork Trinity Trail in Six Rivers National Forest is a long-time favorite of botanizers. Diverse habitats mean diverse plants. The trail is well graded but sometimes weakly maintained, 4 miles each way to the river, but all of us won't go all the way. Bring lunch and 2 quarts of water; dress for the weather. The trailhead is 2 hours from Arcata. Carol plans to spend the night after the hike someplace closer to there, so as not to have to hurry back. Meet at 8:00 a.m. at Pacific Union School (3001 Janes Rd., Arcata).

Bring a hand lens if you have one. Contact Carol Ralph 822-2015 for more information.

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.

September 23, Saturday. Fall Native Plant Sale
