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.
