Abstract
Landslide inventory (1953-1996), Andrews Experimental Forest and Blue River Basin. This layer is a combination of data from four landslide inventory efforts that have been conducted in the area beginning in the late 1960's. Data represent landslide occurrences between 1953 and 1996. Data are in the UTM coordinate system; zone 10, NAD27. The data table that describes the characteristics of the landslides inventoried in the following: Individual layers tied to inventories by Ted Dyrness, Fred Swanson, Dan Marion, and Matt Wallenstein were appended and linked to the shape file. This file is associated with the slideinv layer, which is a combination of data from four landslide inventory efforts that have been conducted in the area beginning in the late 1960's. Points have been screen digitized from field maps using streams, roads, contour lines, and harvest units as reference layers.
Coverage
Temporal coverage: 1953-01-01 to 1996-12-31
Geographic coverage: Blue River Basin and Andrews Experimental Forest within the Willamette National Forest, western Cascades, Oregon, USA.
Spatial coverage:
Bounds: W -122.31051300, E -122.13123600, N 44.32256900, S 44.18873500
Purpose
- These data collection efforts represent a variety of research objectives. Primarily data were collected to document landslide occurence in managed forest lands of the western Cascade Range and to assess the impact of road-building and timber harvest on landslide magnitude and frequency.

Abstract
- The H.J. Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics.
- Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition.
- The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources.

Study Area Description
-
Long-Term Ecological Research The Andrews Forest is situated in the western Cascade Range of Oregon, and covers the entire 15,800-acre (6400-ha) drainage basin of Lookout Creek. Elevation ranges from 1350 to 5340 feet (410 to 1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. These forests are among the tallest and most productive in the world, with tree heights of often greater than 250 ft (75 m). Streams are steep, cold and clean, providing habitat for numerous aquatic organisms.

Methods
Method Steps
Processing Procedures - GE012
- GE01201:Landslides represented in this data set aret shallow rapid slope failures - debris flows. Large slow-moving features, such as earthflows, are not included. Points have been screen digitized from field maps using streams, roads, contour lines, and harvest units as reference layers. Indvidual layers tied to inventories by Ted Dyrness, Fred Swanson, Dan Marion, and Matt Wallenstein were appended and linked to an info attribute file (slideinv.dat).
Instrumentation:
- Positional accuracy varies by component data set. The Dyrness and Swanson surveys were mapped onto 1:15840 Forest Service base maps. The accuracy of these base maps is unknown. The Marion and Wallenstein surveys utilized 1:24000 Forest Service Primary Base series maps, which to comply with National Map Accuracy Standards.

Indvidual layers tied to inventories by Ted Dyrness, Fred Swanson, Dan Marion, and Matt Wallenstein were appended and linked to an info attribute file (slideinv.dat). This file was exported to a database format.

Processing Procedures - GE012 (2)
- Data were converted from an Arc/GIS coverage to an esri shapefile and projected to NAD83. The attribute table was joined to the shapefile and created a new shapefile with slideinv_table.dbf info. Cleaned up fields that contained no records.
