Assessing and Managing the Ecological Impacts of Paved Roads

Title:Assessing and Managing the Ecological Impacts of Paved Roads Committee on Ecological Impacts of Road Density, National Research Council Reg:$60.00 Web:$54.00 Description All phases of road development from construction and use by vehicles to maintenance 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.

Title:The Geological Record of Ecological Dynamics: Understanding the Biotic Effects of Future Environmental Change Committee on the Geologic Record of Biosphere Dynamics, National Research Council Reg:$42.00 Web:$37.80 Description In order to answer important questions about ecosystems and biodiversity, scientists can look to the past geological record which includes fossils, sediment and ice cores, and tree rings. Because of recent advances in earth scientists ability to analyze biological and environmental information from geological data, the National Science Foundation and the U.S. Geological Survey asked a National Research Council (NRC) committee to assess the scientific opportunities provided by the geologic record and recommend how scientists can take advantage of these opportunities for the nation s benefit. The committee identified three initiatives for future research to be developed over the next decade: (1) use the geological record as a natural laboratory to explore changes in living things under a range of past conditions, (2) use the record to better predict the response of biological systems to climate change, and (3) use geologic information to evaluate the effects of human and non-human factors on ecosystems. The committee also offered suggestions for improving the field through better training, improved databases, and additional funding.
