Paperback. Condizione: New. Print on Demand. This book documents a survey of mass soil movements in the H. J. Andrews Experimental Forest, Oregon, conducted after a severe storm in 1964. The author describes 47 events, ranging from earthflows and slumps to debris avalanches, with volumes varying from 100 to 75,000 cubic yards. The study examines the relationship between these movements and factors such as disturbance caused by road construction, logging, geological conditions, soil types, elevation, and slope. The author concludes that man-caused disturbance is a significant factor in the occurrence of mass soil movements, especially in areas with steep slopes and unstable soils. The book provides insights into the complex interactions between human activities and natural processes in shaping the landscape, highlighting the importance of considering these factors in land management practices.

Paperback. Condizione: New. Print on Demand. This book presents a fascinating exploration of roadside soil stabilization in the Pacific Northwest. The author examines various grass-legume mixtures and legume species to determine their effectiveness in controlling erosion on slopes. The book highlights the importance of selecting suitable plant materials based on site-specific conditions, emphasizing the significance of factors such as moisture levels, slope steepness, and soil fertility. The author provides a comprehensive evaluation of eight legume species, revealing their strengths and limitations in different environments. Through meticulously conducted field experiments, the book demonstrates the effectiveness of straw mulch in enhancing seed establishment and reducing soil movement. The author discusses the benefits of including fast-growing grasses like Italian ryegrass that provide rapid cover, as well as the need for deep-rooted species like shrubs and trees for mass movement prevention. Overall, this book offers valuable insights into the science of roadside soil stabilization, examining both the challenges and successes of various approaches. It underscores the importance of considering site-specific factors and employing appropriate plant materials to achieve effective erosion control, contributing to a better understanding of sustainable roadside management practices.

Paperback. Condizione: New. Print on Demand. This book posits that logging and slash burning in municipal watersheds ought to be considered with far greater scrutiny in light of their capacity to negatively impact physical soil properties. The author presents a revelatory case study of three distinct soil types in the Oregon Coast Range following logging and slash burning. The author finds that while overall effects on soil properties were negligible, severely burned areas did exhibit statistically significant alterations in texture, organic matter, and moisture retention, all of which heighten a soil's susceptibility to erosion. Though severely burned areas were uncommon, comprising merely 8% of the total area studied, the author emphasizes that their increased risk of erosion warrants the implementation of judicious slash-burning practices and thorough post-burn erosion control strategies.

Paperback. Condizione: New. Print on Demand. This book examines how removing forest floor cover affects soil temperatures and the depth of permafrost in black spruce and feathermoss communities in Alaska's interior. The author investigates the impact of fire and mechanical removal of forest floor layers, concluding that mechanical removal has the most significant effect on soil temperature and permafrost depth. Revegetation patterns after treatment are also discussed. Ground vegetation and tall shrub recovery was most successful on burned plots, while mosses were slowest to recover on heavily disturbed plots. This book contributes to our understanding of the crucial role of the forest floor in maintaining permafrost and regulating soil temperatures in this critical ecosystem, providing valuable insights for managing taiga ecosystems in a changing climate.

Paperback. Condizione: New. Print on Demand. This insightful volume explores the hydrological properties of three small watersheds in the Western Cascades of Oregon, providing a comprehensive analysis of soil characteristics and their impact on water storage and movement. The author meticulously classifies and maps eight soil series, uncovering significant variations in water movement and storage capacity. This detailed examination reveals the influence of stone content on soil properties, leading to the redefinition of four soil series based on particle size and stone volume. The study highlights the need for accurate soil classification and mapping techniques, emphasizing the crucial role of stone content in understanding soil hydrology. The author's findings offer valuable insights for land managers and researchers seeking to optimize water management and conservation strategies in forested upland areas, underscoring the significance of soil properties in shaping the hydrological dynamics of watersheds.

Paperback. Condizione: New. Print on Demand. This book offers an illuminating study of forest floors and soils in old-growth true fir-hemlock stands, examining their characteristics and nutrient content. The author's comprehensive analysis provides insights into the significance of these layers and their potential impact on tree regeneration and nutrient cycling. By presenting data from 46 undisturbed plots across the Cascade Range, the book deepens our understanding of forest ecosystem dynamics and highlights the need for further exploration to fully grasp the complexities of these ecosystems.
