Shallow, rapid landslides are common events in steep terrain of the Pacific Northwest. The effect of landslides on timber growth potential of forest land was estimated by examining a 30-yr history of clearcutting and landsliding in the western Oregon

I he distribution of native vegetation and the rate of forest growth in relation to soils were studied on two transects. One of the transects extended for about 4 miles in Iowa and Sauk Counties; it crossed the Wisconsin River in a southnorth directi

The fertility of pumice soils is difficult to assess by laboratory analysis. A biological assay of growth responses yields more meaningful information. Four pumice soils common in central Oregon were assayed in the greenhouse using ponderosa pine as

The majority of the land in the low-lying hills adjacent to the Willamette Valley is not suited for agriculture due to the nature of the soils and topography, and supports a cover of Douglas fir, mixed Douglas-fir-Oregon white oak, and oak stands. Sc

Water use in a pumice soil in central Oregon increased significantly with increased density of a sapling ponderosa pine (Pinus ponderosa Laws.) stand. Study plots were thinned to 62, 125, 250, 500, and 1,000 trees/acre and replicated six times. Soil
