This guidebook describes the High Peak/Moon Creek Research Natural Area, a 617.5-ha (1,526-ac) tract of coniferous forest containing stands dominated by 100- to 150-year-old Douglas-fir, a small old-growth (500+ years) Douglas-fir stand, and riparian vegetation within the western hemlock zone of the Coast Range in western Oregon.

Roger Lake Research Natural Area (RNA), a 174.7-ha reserve in north-central Washington, contains a rich diversity of landforms, plant communities, and wildlife habitats. Spreading outward from the lake itself, sedge and sphagnum fens give way to upland coniferous forest, granitic cliffs, and a relictual, high-altitude big sagebrush-whitebark pine (Artemisia tridentata-Pinus albicaulis) meadow. Five sensitive plant species and several vertebrate species that are rare in the region occur in the RNA. Dynamic ecological processes in action in the RNA are revealed in the paludification of the forest edge; aging, broken beaver dams; and widespread bark beetle-induced conifer mortality.

Estimates of national forest recreation use are available at the national, regional, and forest levels via the USDA Forest Service National Visitor Use Monitoring (NVUM) program. In some resource planning and management applications, analysts desire recreation use estimates for subforest areas within an individual national forest or for subforest areas that combine portions of several national forests. In this research note we have detailed two approaches whereby the NVUM sampling data may be used to estimate recreation use for a subforest area within a single national forest or for a subforest area combining portions of more than one national forest. The approaches differ in their data requirements, complexity, and assumptions. In the "new forest" approach, recreation use is estimated by using NVUM data obtained only from NVUM interview sites within the area of interest. In the "all-forest information" approach, recreation use is estimated by using sample data gathered on all portions of the national forest(s) that contain the area of interest.

This guidebook describes the Forest Peak Research Natural Area (RNA), a 62.8-ha (153.3-ac) tract containing a mature Douglas-fir (Pseudotsuga menziesii) forest and a grass bald within the Willamette Valley Foothill Ecoregion. Forest Peak RNA also contains an undisturbed third-order stream reach.

This guidebook describes the Saddle Bag Mountain Research Natural Area, a 121-ha (300-ac) tract established to represent an old-growth remnant of Pacific silver fir (Abies amabilis) and western hemlock (Tsuga heterophylla) forest in the Oregon Coast Range.

This guidebook describes the Grass Mountain Research Natural Area, a 377-ha (931-ac) tract in the Oregon Coast Range. The area supports a grass bald complex surrounded by stands dominated by noble fir (Abies procera) and/or Douglas-fir (Pseudotsuga menziesii) in the overstory, and western hemlock (Tsuga heterophylla) in the understory. The area also contains a small rock garden plant community along high-elevation ridges, and young Douglas-fir forest that originated from a wildfire. Headwaters of high-elevation, Oregon Coast Range streams are surrounded by noble fir forest and add to the site diversity.

This guidebook describes Benjamin Research Natural Area, a 258-ha (637-ac) tract originally established to represent an example of the western juniper/Idaho fescue (Juniperus occidentalis/Festuca idahoensis) plant association. Subsequent field surveys indicate the predominant vegetation is best characterized as the western juniper/low sagebrush/Idaho fescue plant association. Current vegetation is dominated by western juniper woodland with an understory vegetation mosaic that varies with soil depth. Low sagebrush (Artemisia arbuscula Nutt.) occurs as the major shrub in shallow or rocky soils, and Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis Beetle and Young) predominates in areas with deeper or more finely textured soil.

Example embodiments relate to a bad area managing method of a nonvolatile memory device. The nonvolatile memory device may include a plurality of memory blocks and each block may contain memory layers stacked on a substrate. According to example embodiments, a method includes accessing one of the memory blocks, judging whether the accessed memory block includes at least one memory layer containing a bad memory cell. If a bad memory cell is detected, the method may further include configuring the memory device to treat the at least one memory layer of the accessed memory block as a bad area.

A processor determines whether a first program is under execution when a second program is executed, and changes a setting of a memory management unit based on access prohibition information so that a fault occurs when the second program makes an access to a memory when the first program is under execution. Then, the processor determines whether an access from the second program to a memory area used by the first program is permitted based on memory restriction information when the fault occurs while the first program and the second program are under execution, and changes the setting of the memory management unit so that the fault does not occur when the access to the memory area is permitted.
