Squaw Flat Research Natural Area (RNA) was established to represent an undisturbed, mixed conifer forest. The RNA runs along Jackson Creek, a tributary of the South Umpqua River. Douglas fir (Pseudotsuga menziesii) and ponderosa pine (Pinus ponderosa) dominate the flat, dry area in the eastern portion of the RNA. Sugar pine (Pinus lambertiana), incense cedar (Calocedrus decurrens) and white fir (Abies concolor) are also present. The understory includes Oregon grape (Berberis spp.), oceanspray (Holodiscus discolor), and poison oak (Toxicodendron diversilobum). The western portion of the area is dominated by white fir and western hemlock (Tsuga heterophylla). Understories on the slopes consist of swordfern (Macrothelypteris torresiana), salal (Gaultheria shallon), Oregon grape and moss. White oak (Quercus alba) is present around the edges of several deep soiled meadows. At least ten species of grass, as well and many forbs, rushes, and sedges grow in these meadows.
