Field Trips & Plant Walks

Piperia elegans

August 3, Saturday. 10 a.m.-1 p.m. Orchids in the Dunes. Orchids are a very diverse group, including quite dainty species. Join Carol Ralph to learn about five species of orchid that live in the Lanphere Dunes. Four might be blooming.  Walk 1-2 miles, partly on soft sand. Meet at Pacific Union School (3001 Janes Rd., Arcata) to carpool to the protected site.  Co-sponsored by CNPS and Friends of the Dunes. Attendance limited. Call 707-444-1397 to RSVP.

August 4, Sunday.  Lost Man Creek Day Hike.  The lower part of the Lost Man Creek Trail in Redwood National Park is through lush, old growth redwoods.  The upper part of the trail was clearcut immediately before the park acquired the land in the 1970s.  With the book “The Last Redwoods and the Parkland of Redwood Creek” (1969, a Sierra Club-Ballantine book) in hand, we will compare some dramatic photos of the past devastation with what is there now, 50 years later. The first 1.5 mile is almost level; beyond that it goes uphill steeply.  We will walk until we are half-tired and return the same way. Meet at 9:00 a.m. at Pacific Union School (3001 Janes Rd., Arcata).  Dress for being outside all day in a shady forest.  Bring lunch and water.  Return late afternoon.   Contact: Carol, 707-822-2015.

September 15, Sunday.  Exploring Stone Lagoon’s North End.  On this day-hike from the parking area at the north end of Stone Lagoon we will poke along the water’s edge finding wetland plants, walk along the spit finding sand dune plants, and walk along the base of the bluff finding coastal bluff plants.  Meet at 9:00 a.m. at Pacific Union School (3001 Janes Rd., Arcata).  Dress for the weather, including wind.  Bring lunch and water.  Return late afternoon.  Contact: Carol, 707-822-2015.

September  11, Wednesday. 7:30 p.m. “Astounding Astragalus in Humboldt County and Beyond.”  Astragalus (the milkvetches) is a large and particularly diverse genus within the western United States, with a large number of rare and endemic taxa.  HSU Professor Kerry Byrne will provide an overview of the genus Astragalus in California and beyond, highlight some of the interesting species found in Humboldt Co., and describe some of the ongoing conservation research with a federally endangered Astragalus species in southern Oregon.

Used Botanical Book Sale:  We will be selling used botanical books at the September 11 evening program! Everything priced to sell, to benefit the chapter!  If you have books to contribute, or if you can help organize the books, contact Carol at or 707-822-2015.
