This authoritative volume brings together some of the world's leading researchers, academics, practitioners and transportation agency personnel to present the current status of the ecological sustainability of the linear infrastructure – primarily road, rail and utility easements – that dissect and fragment landscapes globally. It outlines the potential impacts, demonstrates how this infrastructure is being improved, and how broad ecological principles are applied to mitigate the impact of road networks on wildlife.
Research and monitoring is an important aspect of road ecology, encompassing all phases of a transportation project. Handbook of Road Ecology covers research and monitoring to span the entire project continuum – starting with planning and design, through construction and into maintenance and management. It focuses on impacts and solutions for species groups and specific regions, with particular emphasis on the unique challenges facing Asia, South America and Africa.
Handbook of Road Ecology offers a comprehensive summary of approximately 30 years of global efforts to quantify the impacts of roads and traffic and implement effective mitigation. As such, it is essential reading for those involved in the planning, design, assessment and construction of new roads; the management and maintenance of existing roads; and the modifying or retrofitting of existing roads and problem locations. Handbook of Road Ecology is an accessible resource for both developed and developing countries, including government transportation agencies, Government environmental/conservation agencies, NGOs, and road funding and donor organisations.
Please note: this book was previously announced with the title Ecology of Roads: A Practitioner's Guide to Impacts and Mitigation

Associate Professor Rodney van der Ree has studied the impacts of human activities on biodiversity since the mid 1990s. His current focus includes urban ecology and road ecology, with a strong emphasis on improving research and monitoring and ensuring evidence-based information contributes to the design and management of infrastructure. Rodney is currently the Deputy Director of the Australian Research Centre for Urban Ecology at the Royal Botanic Gardens Melbourne and The University of Melbourne. He was awarded the Graeme Caughley Travelling fellowship in 2014 to promote and enhance road ecology in developing countries.
Daniel Smith is a research associate and member of the graduate faculty in the Department of Biology at the University of Central Florida and a member of the National Academies Transportation Research Board Subcommittee on Ecology and Transportation. Dr. Smith has 20+ years of experience in the fields of ecology and environmental planning. His primary focus is studying movement patterns and habitat use of terrestrial vertebrates and integrating conservation, transportation and land-use planning. He received the 2014 land conservation and planning award from the Florida Wildlife Federation for his outstanding contributions to sound use and management of Florida's natural resources.
Clara Grilo obtained her doctorate in Conservation Biology from the University of Lisbon (Portugal). Her primary interest is applied ecological research in support of active conservation projects. Over the last years, much of her research has focused on the impact of anthropogenic changes to the landscape and effects on wildlife. Currently, she is coordinating research projects on road ecology, namely the effects of roads on the abundance, spatial behavior, population genetic structure and risk of mortality on owls and mammals and the effectiveness of measures to reduce the negative effects of roads on wildlife.

"[...] A proper Handbook that deserves to be on a shelf within reach of anyone with day to day involvement in planning, maintaining and improving the environmental impact of our roads."

"In conclusion, the book provides a very important contribution to the understanding of the effects of linear infrastructures on wildlife. It is 'reader friendly' and practice driven, and I'm sure it will generate both further research and collaboration in the field, so that the highest beneficiary will be the natural vegetation and fauna."
– Bulletin of the Eurasian Dry Grassland Group, 1 November 2015
"Authors focused and wrote concisely, which means the contents are readily digestible and consequently easy to use for students in both academic and more technical and practical disciplines [...] Another major strength of the Handbook of Road Ecology is its comprehensive international coverage. Each of the three editors is from a different continent, and the other contributors cover an impressively diverse range of countries, developed and developing, and cultures. This means that in addition to providing a comprehensive compendium for people seeking information on ecologically sustainable road construction and planning, the volume is also valuable for learning from approaches and solutions applied in different regions [...] The cross-referencing of chapters is helpful and enables readers to find other chapters relevant to a particular topic with ease. The editors have clearly put considerable effort into ensuring the book is concise and easy to use for all those who are interested in the challenges of ecologically sustainable construction and planning of roads. Each chapter begins with a succinct summary and bullet points and ends with suggestions for further reading, which makes it easy to use as a reference work from which relevant information can be located easily and quickly. The book is richly illustrated with colored photographs and figures."
