This guidebook describes major biological and physical attributes of the 433-ha (1,070-ac) Grayback Glades Research Natural Area. The area supports high- elevation examples of white fir–Shasta red fir (Abies concolor[Gord. + Glend]–Abies magnifica var. shastensis) forest along the crest of the Siskiyou Mountains in southwestern Oregon. High-elevation Sitka alder (Alnus viridis ssp. sinuata) glades are also represented on the site. Drainages support large individuals of Port Orford cedar (Chamaecyparis lawsoniana[A. Murray bis]). © 2016, USDA Forest Service. All rights reserved.

Lost Lake Research Natural Area: guidebook supplement 48. Gen. Tech. Rep. PNW-GTR-947. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 28 p. This guidebook describes major biological and physical attributes of the 155-ha (384-ac) Lost Lake Research Natural Area (RNA), in Jackson County, Oregon. The RNA has been designated because it contains examples of a landslide-dammed lake; and a low-elevation lake with aquatic beds and fringing marsh, surrounded by mixed-conifer forest (ONHAC 2010). © 2016, USDA Forest Service.

This guidebook describes Upper Elk Meadows Research Natural Area (RNA), a 90-ha (223-ac) area that supports a mixture of coniferous forest and open, shruband herb-dominated wetlands. The major forest plant association present within Upper Elk Meadows RNA is Pacific silver fir/vine maple/coolwort foamflower (Abies amabilis/Acer circinatum-Tiarella trifoliata).

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 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.

This guidebook describes major biological and physical attributes of the 119-ha (293-ac) Mohawk Research Natural Area. The area supports old-growth Douglas-fir (Pseudotsuga menziesii) forest characterized by plant associations representative of the western Cascade foothills. These include the western hemlock/Oregon grape-salal (Tsuga heterophylla/Berberis nervosa-Gaultheria shallon); western hemlock/Oregon grape/swordfern (Tsuga heterophylla/Berberis nervosa/Polystichum munitum); and western hemlock/Oregon oxalis (Tsuga heterophylla/Oxalis oregana) forest plant associations.

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 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 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.
