Abstract
This guidebook describes Woodcock Bog Research Natural Area (RNA), a 114-ha (281-ac) area located within the Klamath-Siskiyou ecoregion in southwestern Oregon. The RNA includes a hanging fen and stream segment on ultramafic rock and derived soils. Numerous plant species occur within the fens that are endemic to the Klamath-Siskiyou Mountains of southwestern Oregon and northwestern California. Cobra lily (
Darlingtonia californica), and sedges (
Carex spp.) characterize the area. The site also supports very dry, open serpentine forest stands of Jeffrey pine (
Pinus jeffreyi), along with denser stands of Port-Orfordcedar (
Chamaecyparis lawsoniana), Douglas-fir (
Pseudotsuga menziesii), and other conifers typical of the region.
