Orchids are a very diverse group, including quite dainty species. Join Naturalist Carol Ralph to learn about five species of orchids that live in the Lanphere Dunes Unit of the Humboldt Bay National Wildlife Refuge, four of which should be blooming. The walk will be 1 to 2 miles, partly on soft sand. Meet at Pacific Union School, 3001 Janes Rd. in Arcata to carpool to the protected site. R.S.V.P. by contacting Friends of the Dunes at (707) 444-1397 or [email protected]. This walk is co-sponsored by the California Native Plant Society and Friends of the Dunes.
