The Call 2013 Roads and Wildlife Manual CEDR Contractor Report 2018-3 Call 2013: Roads and Wildlife The Roads and Wildlife Manual CEDR Contractor Report 2018-3 Call 2013: Roads and Wildlife The Roads and Wildlife Manual by Eugene OBrien (ROD-IS) Edgar van der Grift (ALTERRA) Morten Elmeros (AU-BIOS) Ryan Wilson-Parr (ROD-IS) Ciarán Carey (ROD-IS) CEDR Contractor Report 2018-3 is an output from the CEDR Transnational Road Research Programme Call 2013: Roads and Wildlife. The research was funded by the CEDR members of Austria, Denmark, Germany, Ireland, Netherlands, Norway, Sweden and the United Kingdom. The aim of the CEDR Transnational Road Research Programme is to promote cooperation between the various European road administrations in relation to road research activities. The topics covered by this Call were developed by TG Research to fulfil the common interests of the CEDR members. The Project Executive Board for this programme consisted of: Lars Nilsson/ANDERS SJOLUND, STA, Sweden (Chair) VINCENT O’MALLEY, TII, Ireland OLA-MATTIS DRAGESET, NPRA, Norway ELKE HAHN, BMVIT, Austria HANS BEKKER/ADAM HOFLAND, Rijkswaterstaat, Netherlands TONY SANGWINE, Highways England, United Kingdom UDO TEGETHOF, BAST, Germany MARGUERITE TROCME, FEDRO, Switzerland MARIANNE LUND UJVÁRI, Danish Road Directorate, Denmark CONTRACTORS: ISBN: 979-10-93321-42-4 DISCLAIMER The report was produced under contract to CEDR. The views expressed are those of the authors and not necessarily those of CEDR or any of the CEDR member countries. Foreword Roads are a crucial part of modern society, allowing people and freight to move to where they are needed. However, the effect of roads is not wholly positive as they do result in habitat fragmentation which has a detrimental effect on these habitats and the species therein. The COST 341 action recognised the need to mitigate against the effects of habitat fragmentation. A key output of that action was the COST 341 Handbook, “WILDLIFE AND TRAFFIC, A European Handbook for Identifying Conflicts and Designing Solutions”. Ten years after the 2003 publication of the COST 341 Handbook, the Conference of European Directors of Roads (CEDR) released their transnational research call 2013: Roads and Wildlife. The call, which funded the projects “SAFEROAD”, “SafeBatPaths” and “Harmony”, aimed to address the conflict between roads and wildlife and to identify more cost-efficient methods for building and maintaining roads, and structures for reducing the impact on wildlife such as fauna passages. CEDR has now commissioned the ECOROAD project partners to produce this CEDR Roads and Wildlife Manual. This manual complements the work of COST 341 and is the result of an integration of the outputs of the “Harmony”, “SAFEROAD” and “SafeBatPaths” projects, along with further input from European road ecology experts. The aim of the manual is to update the information in COST 341 to reflect changes such as those in European Union legislation and policy. This CEDR manual also identifies best practice in areas such as procurement, maintenance and monitoring which received less emphasis in the COST 341 handbook. We envisage this manual acting as a companion to the COST 341 Handbook, providing a basis to consider the effects on wildlife throughout the various stages of the life of a roadway. We hope that the guidance provided herein goes some way to solving the conflict between roads and wildlife.

  • Road Ecology Studies for Mexico: a Review
    Oecologia Australis 17(1): 175-190, Março 2013 http://dx.doi.org/10.4257/oeco.2013.1701.14 ROAD ECOLOGY STUDIES FOR MEXICO: A REVIEW Alberto González Gallina1,* & Griselda Benítez Badillo1 1Instituto de Ecología, AC, Carretera Antigua a Coatepec, No. 351, El Haya, Xalapa 91070, Veracruz, México. E-mail: [email protected], [email protected] ABSTRACT The main goal of this study is to perform review of road ecology issue in Mexico. More specifically we addressed: 1) a general overview of road construction from pre-Colonial times to the present; 2) a description of the historical background context for understanding modern Mexico´s highway system; 3) a review of the main results of the road ecology studies in Mexico and 4) the Mexican policy on mitigation actions. Finally, we discuss the key points of future research and road policies. There is already some research, mainly in road mortality, which gives us a glimpse of the impact of roads on Mexican wildlife. Mexico has wide diversity of habitats and ecosystems. So, to gain knowledge on the impact of roads on wildlife so that efficient corrective and preventive actions can be planned much more study is required. Unfortunately, most of the studies carried out in Latin America, and specifically in Mexico, were done only over Environmental Impact studies for large scale infrastructure projects. There is still a long way to go in Mexico for roadways to become environmentally friendly, but little by little the issue is gaining importance and hopefully more and more academics, policy makers and people in general will become interested and get involved, so that this goal can be achieved.

  • Roadside Ecology
    Michael Brereton NRS 534 Final White Paper Roadside Ecology There are very few species in the recent history of our planet Earth that have made such a lasting impact on the surface of the world as us. Human activity has left the landscape of our planet forever changed as we continue to expand our territory to fit our exponentially growing population. One of the signs of a rapidly growing civilization is the road. Whether paved or dirt, roads are used by humans to transport ourselves great distances at the cost of our natural surroundings. Roads are a major driver of habitat fragmentation, a term used in ecology to describe the fracturing or dividing of a natural landscape type by an impassible barrier. The creation of roads clears large areas of land and reduces forest cover, furthering an ever-growing loss of habitat for arboreal species to human growth. The constant mowing of roadsides allow invasive exotic species to colonize. Roads can reduce the range for foraging and hunting animals, and those who dare to cross risk death by vehicle. Roads can also change the physical aspect of an environment, causing greater risk to pollution and flooding. In order to continue living in harmony with the flora and fauna of our natural surroundings, we must employ new ideas and technologies to our roads. The study of road ecology will provide the answers we need to have safer roads for both ourselves and our natural world. Road ecology sits at the crossroads between many different scientific fields, including invasion ecology, hydrology, stream ecology, soil science, and many more.

  • The Influence of Economics, Politics and Environment on Road Ecology in South America Alex Bager1, Carlos E
    Chapter 50 THE INFLUENCE OF ECONOMICS, POLITICS AND ENVIRONMENT ON ROAD ECOLOGY IN SOUTH AMERICA Alex Bager1, Carlos E. Borghi2 and Helio Secco1 1Brazilian Center for Road Ecology Research, Department of Biology, Federal University of Lavras, Lavras, Brazil 2CIGEOBIO (UNSJ‐CONICET), CUIM, Facultad de Ciencias Exactas, Físicas y Naturales, San Juan, Argentina SUMMARY Rapid economic growth in several South American countries combined with high species diversity in tropical regions has raised great concern among ecologists on the future of wildlife in those areas. One of the con- sequences and drivers of economic growth is widespread infrastructure development. The economic and social development of most countries in South America is a higher priority than biodiversity conservation, especially when compared with transport infrastructure. Over the past decade, several research groups have focussed on the impacts of roads on wildlife in South America. 50.1 The economic development of some countries in South America has strongly influenced the expan- sion of road networks. 50.2 Although there are numerous organisations involved in planning, development and administration of highways, only few of them evaluate the impacts on biodiversity. 50.3 Numerous protected areas in South America are directly and indirectly affected by roads. 50.4 Road ecology is an emerging discipline in South America, and Brazil and Argentina are leading the field. There are enormous challenges to effectively incorporate ecological considerations into the planning, design, construction and operation of roads in South America. While much of the current practise has been adapted from international experience, the time has come to invest in local experts and improve the quality of the scientific knowledge generated from within South America.

  • Economic, Socio-Political and Environmental Risks of Road Development in the Tropics
    Current Biology Review Economic, Socio-Political and Environmental Risks of Road Development in the Tropics Mohammed Alamgir, Mason J. Campbell, Sean Sloan, Miriam Goosem, Gopalasamy Reuben Clements, Mahmoud I. Mahmoud, and William F. Laurance* Centre for Tropical Environmental and Sustainability Science, and College of Science and Engineering, James Cook University, Cairns, Queensland, 4878, Australia *Correspondence: [email protected] https://doi.org/10.1016/j.cub.2017.08.067 It is projected that 25 million km of new paved roads will be developed globally by 2050 — enough to encircle the planet more than 600 times. Roughly 90% of new roads will be built in developing nations, frequently in tropical and subtropical regions with high biodiversity and environmental values. Many developing nations are borrowing from international lenders or negotiating access to their natural resources in order to expand their transportation infrastructure. Given the unprecedented pace and extent of these initiatives, it is vital to thoroughly assess the potential consequences of large-scale road and highway projects. In appropriate contexts and locales, new roads can promote sizeable economic and social benefits. If poorly planned or implemented, however, new roads can provoke serious cost overruns, corruption and environmental impacts, while generating sparse economic benefits and intense social and political conflict. Using examples from developing nations, we identify risks that can hinder road projects in wet and dry tropical environments. Such risks, we assert, are often inadequately considered by project proponents, evaluators and the general public, creating a systematic tendency to overestimate project benefits while understating project risks. A more precautionary approach is needed to reduce risks while maximizing benefits of new road projects in the tropics.

The research papers are published in the period 1977-2017 and cover a wide range of topics. The systematic growth in the number of scientific publications on wild boar is an indication of growing environ- mental and social concerns about the species, which is in turn a reflection of their increasing presence across Europe. The research shows that wild boar populations are increasing in most areas of Europe. For some, a growing wild boar population is a positive development, indicating better habitat conditions and the presence of an additional huntable species. Others are strongly opposed to an expanding population and cite the increasing negative impacts such as agricultural damage and road accidents. The growing populations can be explained by a multitude of variables including climate change, agricultural practices, and increasing human pressures in rural areas (leisure activities, agriculture, …).
