This guidebook describes Fox Hollow Research Natural Area (RNA), a 66-ha (163-ac) area that supports dry-site Douglas-fir (Pseudotsuga menziesii)-ponderosa pine (Pinus ponderosa) forest within the Oregon Coast Range ecoregion. Major forest plant associations represented at Fox Hollow RNA include Douglas-fir/ salal/western swordfern (Pseudotsuga menziesii/Gaultheria shallon/Polystichum munitum) forest and Douglas-fir/Oregongrape (Pseudotsuga menziesii/Berberis nervosa) forest. Other forested communities are represented within the RNA in minor amounts including: Douglas-fir/poison oak (Pseudotsuga menziesii/ Toxicodendron diversilobum) forest, ponderosa pine-Douglas-fir/California fescue (Pinus ponderosa-Pseudotsuga menziesii/Festuca californica) woodland, and ponderosa pine-Douglas-fir-California black oak (Pinus ponderosa-Pseudotsuga menziesii-Quercus kelloggii) woodland.

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.

This guidebook describes Forest Creeks Research Natural Area, a 164-ha (405-ac) area comprising two geographically distinct canyons and associated drainages. The two units have been established as examples of first- to third-order streams originating within a ponderosa pine (Pinus ponderosa) zone. The two riparian areas also represent examples of the mountain alder-redosier dogwood (Alnus incana-Cornus sericea ssp. sericea), and the redosier dogwood-mockorange (Cornus sericea ssp. sericea-Philadelphus lewisii) plant associations.

This guidebook describes Cherry Creek Research Natural Area, a 239-ha (590-ac) area that supports old-growth Douglas-fir-western hemlock (Pseudotsuga menziesii-Tsuga heterophylla) forest occurring on sedimentary materials in the southern Oregon Coast Range. Major plant associations present within the area include the western hemlock/Oregon oxalis (Oxalis oregana) plant association, the western hemlock/evergreen huckleberry (Vaccinium ovatum) plant association, and the western hemlock/rhododendron-Oregon grape (Rhododendron macrophyllum-Berberis nervosa) plant association. A northern spotted owl population (Strix occidentalis caurina) also uses the area.

This guidebook describes major biological and physical attributes of the 243-ha (600-ac) Round Top Butte Research Natural Area. The area supports high-quality examples of valley upland grasslands and savanna of the Cascade foothills. Plant communities include Oregon white oak (Quercus garryana) savanna and open woodland with forbs and grasses; ponderosa pine (Pinus ponderosa)-Oregon white oak woodland; bluebunch wheatgrass-California oatgrass-Lemmon's needlegrass (Pseudoroegneria spicata-Danthonia californica-Achnatherum lemmonii) grasslands; and tufted hairgrass (Deschampsia cespitosa)-California oatgrass vernally flooded prairie.
