Sustainable Landscaping


Book Description

Sustainable landscaping involves a set of practices implemented by landscape practitioners to help solve environmental concerns. Continuing in the tradition of its predecessor, the second edition of Sustainable Landscaping: Principles and Practices examines underlying landscaping issues that adversely affect the environment and illustrates alternative methods that result in positive outcomes. This textbook examines all phases of landscaping in both residential and commercial environments, from design to construction and implementation to maintenance. Firmly anchoring landscaping practices in the context of sustainability, this book explores topics including choosing appropriate plants and using plants for specific effects, such as shading, water quality and quantity, soil health and optimal preservation techniques, pesticide usage and its inherent dangers, energy consumption, and resource management and waste reduction. Sustainable Landscaping also provides a thorough grounding in pertinent issues and terminology for each topic, followed by practical solutions applied by landscape professionals. Each chapter includes learning objectives and case studies of actual sustainable landscape activities. Contains updated government statistics and data, graphs, tables, and color photographs throughout. Provides background information and sustainable solutions for students, homeowners, and landscaping professionals to effectively design and manage landscapes. Author Dr. Marietta Loehrlein is a Professor Emeritus of Horticulture and Landscaping at Western Illinois University in Macomb, IL, USA. While there, she developed a new course, "Sustainable Landscaping," and wrote the first edition of this textbook, which was also the first of its kind to address the subject.




Assessing and Managing the Ecological Impacts of Paved Roads


Book Description

All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.




Reversibility of Chronic Disease and Hypersensitivity, Volume 5


Book Description

The clinical approaches to the chronic degenerative diseases that drain our resources, and compromise our well-being, have become almost exclusively symptom-focused. The common wisdom is that they are idiopathic with final outcomes to be managed rather than prevented or cured. That they are potentially reversible rarely enters any discussion between doctor and patient. Reversibility of Chronic Disease and Hypersensitivity, Volume 5: Treatment Options of Chemical Sensitivity, the final volume of this set, offers a much different perspective on chronic degenerative disease; one that disputes the idiopathic label attached to most, as well as the usual fatalistic prognosis.
